Description

The present invention relates to an article holder capable of detecting the load of an article and a fixture equipped with the article holder.

In stores such as supermarkets and convenience stores, fixtures are used to display items on shelves or on tables. In addition, in such stores, inventory is taken at regular intervals for inventory management, but to reduce the labor required, technology has been developed that installs various sensors on the fixtures and uses the sensors to detect when items are taken in and out of the fixtures, allowing inventory management to be completed in a short period of time. In recent years, the introduction of unmanned stores has been considered to reduce labor costs, and the above technology is also being applied in such cases.

One example of such technology is that described in Patent Document 1. The fixture in Patent Document 1 is capable of displaying items on a shelf. The shelf is equipped with a base member, a top plate on which a plurality of items can be placed in the width direction of the base member, and a load detection sensor disposed between each top plate and the base member, and each load detection sensor is connected to a computer. Each top plate is used by placing one type of item on it. The computer is also configured to have the identification number of each load detection sensor, the type of product placed on each top plate, the weight of each product, etc. input in advance, and the number of items in stock placed on each top plate can be easily managed based on the load detected by each load detection sensor.

In such fixtures, it is important to improve the visibility of the items and display them attractively by changing the size and position of the area on the shelf where the items are placed depending on the size and type of item, sales status, sales time period, campaign, etc., in order to increase the desire to purchase the items. However, in the fixture of Patent Document 1, the load detection sensor is fixedly installed on the base member, so there are limitations to changing the layout of the items while still allowing load detection.

The present invention was developed to address these problems, and aims to provide an item placement device and fixture that allows load detection while also allowing the layout of items to be freely changed.

In order to solve the above problems, the article holder of the present invention comprises:
An article placement device comprising: a base member; a plurality of top plates arranged in a width direction on the base member; and a load detection sensor arranged between each of the top plates and each of the base members for detecting a load applied to each of the top plates,

A partition member is attached to the base member to partition the space above the adjacent top plates, and the partition member and the top plates are each supported separately by the base member and spaced apart from each other .
According to this feature, the support member can be moved in the width direction of the base member to change the installation positions of the load detection sensor and the top plate, so that top plates with different width dimensions can be combined and arranged on the base member, allowing the layout of items to be freely changed while still enabling load detection.

The table has a tabletop with a minimum width and a tabletop with the same depth dimension as the minimum width tabletop and a width dimension that is a natural number multiple of the minimum width tabletop, and the base member has a width dimension that is a natural number multiple of the minimum width tabletop.
According to this feature, a wide article placement area can be secured on the base member by combining a top plate with a minimum width with a top plate with a width dimension that is a natural number multiple of the minimum width.

The base member is characterized in that it has a box shape that opens upward.
According to this feature, the top plate, the load detection sensor, and the support member can be handled in a state where they are assembled to the box-shaped base member.

The base member has engaged portions that are engageable with engaging portions provided on the support member and that are arranged at equal intervals in the width direction.
According to this feature, the support member can be reliably positioned at any desired position in the width direction of the base member.

The tabletop is characterized in that downwardly extending ribs are provided on both sides of the tabletop.
According to this feature, it is possible to prevent objects from being pinched vertically between adjacent top plates by the downwardly extending ribs.

The article holder of the present invention comprises:
An article placement device comprising: a base member; a plurality of top plates arranged side by side in a width direction on the base member; and a load detection sensor arranged between each of the top plates and each of the base members for detecting a load applied to each of the top plates,
The item placement area on the top plate is configured with different width dimensions by the top plate and a partition member whose widthwise mounting position can be changed relative to the top plate, and the load detection sensor is attached to a support member whose widthwise position can be changed relative to the base member.
According to this feature, the support member can be moved in the width direction of the base member to change the installation positions of the load detection sensor and the top plate, so that load detection units with different width dimensions of the item loading area formed by the top plate and partition member can be combined and arranged on the base member, allowing the layout of the items to be freely changed while still enabling load detection.

The article placement area is characterized in that the width dimension can be adjusted by changing the attachment position of the partition member in the width direction relative to the top plate.
According to this feature, the width dimension of the article placement area can be changed using the same top plate and partition members, so that the layout of articles can be freely changed using a small number of parts.

The fixture of the present invention is
This shelf is characterized by comprising a pair of left and right pillars extending from the floor surface, and a pair of brackets removably attached to each of the pillars, with the item placement device being placed across the pair of brackets.

As shown in FIG. 2, the display shelf section 3 comprises a base member 10 supported by being spanned by a pair of left and right brackets 7, 7, a plurality of load detection units 11, 11, ... arranged side by side in the left-right direction on the base member 10, a stopper member 12 attached to the front end of the base member 10, partition fixing plates 14, 15 arranged in front of and behind the load detection units 11, 11, ... and fixed to the base member 10, and a plurality of partition members 16, 16, ... supported across the front and rear partition fixing plates 14, 15. Different types of items are placed on each of the load detection units 11, 11, ....

The display shelf section 3 of this embodiment also includes a plurality of load detection units 110 that are different in size from the load detection units 11, and the load detection units 11 and the load detection units 110 can be selectively combined and freely arranged on the base member 10 (see Figures 10 to 12). First, the display shelf section 3 using the load detection units 11 will be described.

As shown in Figures 3 and 4, the base member 10 is composed of a bottom plate portion 10a having a rectangular shape when viewed from above, a front plate portion 10b rising from the front end of the bottom plate portion 10a, side plate portions 10c and 10d rising from both left and right ends of the bottom plate portion 10a, and a back plate portion 10e rising from the rear end of the bottom plate portion 10a. In other words, the base member 10 is box-shaped and opens upward. The side plate portions 10c and 10d of this base member 10 are separated left and right by a width dimension L of 30.

As shown in FIG. 3, a plurality of through holes 10f, 10f, ... are formed at a position slightly rearward of the front-rear center of the bottom plate portion 10a, spaced apart by width dimension L1 in the left-right direction. In addition, a slit 10g for wiring that penetrates vertically is formed in the center of the back side of the bottom plate portion 10a. In addition, a control unit 13 is fixed by a mounting member 13a to the center of the lower surface of the bottom plate portion 10a, and the load detection units 11, 11, ... are connected to the control unit 13. Specifically, a plurality of wirings 30 (the same number as the through holes 10f, 10f, ...) extending from the control unit 13 are arranged on the upper surface side of the bottom plate portion 10a through the slit 10g, and the connectors (not shown) at the ends of the wirings of the strain gauges described later that extend from each load detection unit 11 can be connected to the end connectors of each wiring 30. In addition, reinforcing members 17, 18 are fixed to the upper surface of the bottom plate portion 10a at a distance in the front-rear direction. In addition, it is not limited to providing one control unit 13 for one display shelf unit 3, but two or more control units 13 may be provided for one display shelf unit 3, or one control unit 13 may be provided for multiple display shelf units 3. In addition, the number of through holes 10f and slits 10g provided for one display shelf unit 3 can be freely changed.

The front reinforcing member 17 is composed of a first portion 17a that is U-shaped and extends in the left-right direction in a downward cross-sectional view, a second portion 17b that extends forward from the lower end of a front wall portion 17d of the first portion 17a, and a third portion 17c that extends rearward from the lower end of a rear wall portion 17e of the first portion 17a, and the lower surfaces of the second portion 17b and the third portion 17c are fixed to the upper surface of the bottom plate portion 10a by welding. In other words, the reinforcing member 17 is hat-shaped in a cross-sectional view. The reinforcing member 17 may be fixed to the bottom plate portion 10a by bolts and nuts, etc.

In addition, slits 17f, 17f, ... are formed at the lower end of the wall portion 17e as engaging portions that penetrate from front to back and overlap with the through holes 10f, 10f, ... in the front to back direction in front view. That is, the line segment connecting the slits 17f and the through holes 10f is parallel to a line extending in the front to back direction. The slits 17f have a left-right width dimension L2, and the width dimension from the left-right center of the slits 17f to the left-right center of the adjacent slits 17f is width dimension L3. The width dimension L3 between the adjacent slits 17f, 17f is the same as the width dimension L1 between the through holes 10f, 10f (L1 = L3). That is, the through holes 10f overlap with the left-right center of the slits 17f in the front to back direction in front view.

The rear reinforcement member 18 is composed of a first portion 18a that is U-shaped in a downward direction in a side cross section and extends in the left-right direction, a second portion 18b that extends forward from the lower end of the front wall of the first portion 18a, and a third portion 18c that extends rearward from the lower end of the rear wall of the first portion 18a, and the lower surfaces of the second portion 18b and the third portion 18c are fixed to the upper surface of the bottom plate portion 10a by welding. That is, the reinforcement member 18 has a hat shape in a side cross section. In addition, the second portion 18b has a plurality of through holes 18d, 18d, ... formed in the left-right direction corresponding to the through holes 10f, 10f, .... The reinforcement member 18 may be fixed to the bottom plate portion 10a by bolts and nuts, etc.

In addition, a plurality of L-shaped members 19, 19, ... are arranged at a distance in the left-right direction between the front plate portion 10b and the reinforcing member 17 on the bottom plate portion 10a, and between the back plate portion 10e and the reinforcing member 18. The L-shaped members 19 include a fixed plate portion 19a fixed to the bottom plate portion 10a, and an erected piece portion 19b erected upward from the fixed plate portion 19a.

Referring to FIG. 4, the stopper member 12 is made of a translucent synthetic resin and has a first piece 12a extending upward from the front plate portion 10b, a second piece 12b folded back in a front-down direction from the upper end of the first piece 12a, and a third piece 12c folded back in a rear-upward direction from the lower end of the second piece 12b. This stopper member 12 prevents items placed on the load detection units 11, 11, ... from falling forward. In addition, an elastic return force acts on the third piece 12c in a direction pressing against the second piece 12b, so that price tags, POPs, etc. can be held between the second piece 12b and the third piece 12c.

2 and 4, the partition fixing plates 14, 15 are plate-shaped extending in the left-right direction, and the upper ends of the partition fixing plates 14, 15 have a plurality of equally spaced cutout grooves 14a and 15a that open upward and penetrate from front to back. Also, at both left and right ends of the partition fixing plate 14, step portions 14b, 14b that are approximately L-shaped in front view and open upward and outward and penetrate from front to back are formed, and at both left and right ends of the partition fixing plate 15, step portions 15b, 15b that are approximately L-shaped in front view and open upward and outward and penetrate from front to back are formed. Specifically, as shown in FIG. 2, the width dimension L20 between adjacent notched grooves 14a (the width dimension L20 between adjacent notched grooves 14a and step portions 14b) and the width dimension L21 between adjacent notched grooves 15a (the width dimension L21 between adjacent notched grooves 15a and step portions 15b) are the same dimension (L20=L21).

As shown in FIG. 4, the partition fixing plate 14 is press-fitted between the L-shaped member 19 located at the front and the front plate portion 10b, and is attached to the base member 10. The partition fixing plate 15 is press-fitted between the L-shaped member 19 located at the rear and the back plate portion 10e, and is attached to the base member 10. As shown in the enlarged portion of FIG. 4, the bottom of the notch groove 15a is located above the upper surface 11a of the load detection unit 11 (the upper surface of the top plate 20 described later). Although not shown, the bottom of the notch groove 14a is also located above the upper surfaces of the load detection units 11, 11, .... For convenience of explanation, the enlarged portion of FIG. 4 shows a side cross-sectional view in which the center of the notch groove 15a is cut vertically.

The partition member 16 is a plate material made of translucent synthetic resin, and is removably attached by being inserted into the notched grooves 14a, 15a of the corresponding front and rear partition fixing plates 14, 15. In other words, the partition member 16 is supported by being stretched across the front and rear partition fixing plates 14, 15. As described above, the bottoms of the notched grooves 14a and 15a are located above the top surface 11a of the load detection unit 11, so the partition member 16 is attached at a distance of L4 above the top surface 11a of the load detection unit 11.

Next, the load detection unit 11 will be described. As shown in Figures 4 and 5, the load detection unit 11 is mainly composed of a top plate 20 on which an object can be placed, a load detection sensor 21 connected to the underside of the top plate 20, and a rectangular plate-shaped support member 22 that is fixed to the bottom plate portion 10a of the base member 10 and supports the load detection sensor 21. The height dimension L22 of the load detection unit 11 is smaller than the height dimension L23 of the base member 10, so that the load detection unit 11 can be stored within the base member 10.

As shown in Figs. 4 to 6, the top plate 20 includes a top plate portion 20a having a rectangular shape when viewed from above, and ribs 20b, 20b extending vertically downward from both the left and right ends of the top plate portion 20a. The width dimension L5 of the top plate 20 is smaller than the depth dimension L6 of the top plate 20 (L5<L6), and the width dimension L5 of the top plate 20 is the same as the width dimensions L20, L21 between the adjacent notched grooves 14a, 15a (L5=L20, L21. See Fig. 2). In other words, when the display shelf section 3 is assembled, the space Z1 (item placement area) on the top plate 20 of each load detection unit 11 is partitioned in the left-right direction by the partition member 16. The manner in which the partition member 16 is attached will be described in detail later.

The top plate 20 has a simple structure, with the top plate portion 20a and ribs 20b, 20b formed by bending a single metal plate. A rectangular reinforcing plate 20c is fixed to the underside of the top plate portion 20a, and the reinforcing plate 20c has connection portions 20d, 20d spaced apart in the front and rear for connecting the load detection sensor 21. The connection portion 20d is a cylinder with a female thread formed on the inside, and is located in the front-to-back center of the underside of the top plate 20.

The load detection sensor 21 measures the load acting on the top plate 20 and includes a metal piece 21a having a rectangular shape in plan view, a connection member 24 that connects the metal piece 21a to the top plate 20, a connection member 25 that connects the metal piece 21a to the support member 22, screws 21b, 21b that fix the front end of the metal piece 21a to the connection member 24, and screws 21c, 21c that fix the rear end of the metal piece 21a to the connection member 25. The above-mentioned strain gauge (not shown) is attached to the approximate center of the front-rear direction of the metal piece 21a. In addition, through-holes 21e, 21e that penetrate vertically are formed in the front part of the metal piece 21a, and screw holes 21f, 21f that penetrate vertically and have female threads formed on the inner circumferential surface are formed in the rear part of the metal piece 21a.

The connecting member 24 is crank-shaped and includes a first plate portion 24a extending horizontally, a second plate portion 24b rising from the rear end edge of the first plate portion 24a, and a third plate portion 24c extending horizontally rearward from the upper end edge of the second plate portion 24b. Through holes 24d, 24d that penetrate vertically are formed in the first plate portion 24a, and through holes 24e, 24e that penetrate vertically are formed in the third plate portion 24c. In addition, nuts 26, 26 having screw holes that communicate with the through holes 24e, 24e are fixed to the upper surface of the first plate portion 24a.

The connecting member 25 is formed in a crank shape and includes a first plate portion 25a extending horizontally, a second plate portion 25b rising from the rear end edge of the first plate portion 25a, and a third plate portion 25c extending horizontally rearward from the upper end edge of the second plate portion 25b. Through holes 25d, 25d are formed in the first plate portion 25a, and through holes 25e, 25e are formed in the third plate portion 25c, which also penetrate vertically.

The metal piece 21a is connected to the top plate 20 by aligning the through holes 24d, 24d of the first plate portion 24a with the through holes 21e, 21e, and threading the screws 21b, 21b loosely inserted from below into the nuts 26, 26, and aligning the through holes 24e, 24e of the third plate portion 24c with the connection portions 20d, 20d and threading the screw N2 from below. The metal piece 21a is also connected to the support member 22 by aligning the through holes 25e, 25e of the first plate portion 25a with the screw holes 21f, 21f, and threading the screw N3 from below with the through holes 25d, 25d of the first plate portion 25a aligned with the through holes 22c, 22c of the support member 22. As shown in FIG. 4 in particular, when the load detection unit 11 is assembled, the front-rear center of the tabletop 20 is connected to the front end of the metal piece 21a by a connecting member 24, and the front-rear center of the support member 22 is connected to the rear end of the metal piece 21a by a connecting member 25. That is, the tabletop 20 is connected to the metal piece 21a at a position forward of a center line C1 that passes through the front-rear center of the tabletop 20, and the support member 22 is connected to the metal piece 21a at a position rearward of the center line C1. The metal piece 21a, which extends long in the front-rear direction, is disposed along the longitudinal direction of the tabletop 20, which extends long in the front-rear direction, in the left-right direction and in the front-rear center.

As shown in Figures 4, 5, and 7, the support member 22 is formed from a metal plate and includes a base 22a that is generally rectangular when viewed from above, and a protrusion 22b that serves as an engagement portion that protrudes forward from the left-right center of the front end of the base 22a. At the left-right center of the rear end side of the base 22a, through holes 22c, 22c that are aligned in the front-rear direction and penetrate in the up-down direction, and a connection hole 22d provided on the rear side of the through holes 22c, 22c, are formed. A female screw portion is formed on the inner peripheral surface of this connection hole 22d.

Specifically, the support member 22 has a protrusion 22b, through holes 22c, 22c, and a connection hole 22d arranged on a center line C2 that extends forward and backward so as to pass through the center of the left and right of the base 22a. The support member 22 also has a width L7 that is smaller than the width L5 of the top plate 20 (L2>L7). The width L8 of the protrusion 22b is formed slightly smaller than the width L2 of the slit 17f of the reinforcing member 17, so that the protrusion 22b can be inserted into the slit 17f (L2>L8).

As shown in FIG. 4, the support member 22 is fixed to the base member 10 by inserting the protrusion 22b into the slit 17f and threading the screw N1 from below into the through hole 10f, the through hole 18d, and the connection hole 22d, which are stacked vertically.

When the load detection unit 11 is attached to the base member 10, the load of the items placed on the top plate 20 causes strain in the metal piece 21a of the load detection sensor 21. The value of the strain (change in resistance value) detected by the strain gauge is sent to the control unit 13. The control unit 13 pre-stores item information such as the type of item placed on the top plate 20 of each load detection unit 11, the weight per item, and the price per item, and is able to calculate the quantity of items on the top plate 20 of each load detection unit 11 based on the item information and the strain value.

Next, the load detection unit 110 shown in FIG. 11 will be described. The load detection unit 110 is different in size from the load detection unit 11. Specifically, the load detection unit 110 has a top plate 200 that is different in size from the top plate 20 of the load detection unit 11, and a support member 220 that is different in size and shape from the support member 22 of the load detection unit 11. Note that the load detection sensor 21 used in the load detection unit 110 is the same as that used in the load detection unit 11, so a description thereof will be omitted.

As shown in FIG. 8, the top plate 200 includes a top plate portion 200a having a rectangular shape when viewed from above, and ribs 200b, 200b extending vertically downward from both the left and right ends of the top plate portion 200a. The width dimension L9 of the top plate 200 is smaller than the depth dimension L10 of the top plate 200 (L9<L10). The width dimension L9 of the top plate 200 is approximately twice (a natural number multiple) the width dimension L5 of the top plate 20 (L5<L9). Strictly speaking, the width dimension L9 is the sum of twice the width dimension L5 of the top plate 20 and the width dimension L14 of the gap described below, and is slightly larger than twice the width dimension L5. The depth dimension L10 of the top plate 200 is the same as the depth dimension L6 of the top plate 20 (L6=L9).

A rectangular reinforcing plate 200c is fixed to the underside of the tabletop 200, and the reinforcing plate 20c has connection parts 200d, 200d spaced apart in the front and rear for connecting the load detection sensor 21. These connection parts 200d, 200d are located in the front-to-rear center of the underside of the tabletop 200.

As shown in FIG. 9, the support member 220 is formed from a metal plate and includes a base 220a that is generally rectangular when viewed from above, and protrusions 220b, 220b that protrude forward from both left and right ends of the front end of the base 220a as engagement parts. Through holes 220c, 220c are arranged side by side in the front and rear directions on a center line C3 that extends forward and backward so as to pass through the left-right center of the base 220a. In addition, connection holes 220d, 220d are formed on center lines C4, C4 that extend forward and backward so as to pass through the left-right center of the protrusions 220b, 220b.

The width dimension L11 of the support member 220 is smaller than the width dimension L9 of the top plate 200 (L9>L11). The width dimension L12 between the center lines C4, C4, i.e., the distance L12 between the connection holes 220d, 220d, is the same as the width dimension L1 between the through holes 10f, 10f (L1=L12). The width dimension L13 of the protrusion 220b is the same as the width dimension L8 of the protrusion 22b, so that it can be inserted into the slit 17f of the reinforcing member 17 (L8=L13).

Next, a display shelf section 3A actually constructed using only the load detection unit 11 will be described with reference to Figure 10. Note that Figures 10 to 12 show each display shelf section in schematic form, and for ease of explanation, in particular Figures 10(c), 11(c), and 12(c), the thickness of the partition fixing plates 14 and 15 is shown to be thicker than in reality.

10(a), the display shelf section 3A constructed using only the load detection units 11 is designed to allow six load detection units 11, 11, ... to be evenly arranged in the width direction of the base member 10. A gap of width L14 is formed between adjacent load detection units 11, 11, and a gap of width L14 is formed between the load detection units 11, 11 at both the left and right ends and the side plate portions 10c, 10d of the base member 10. In other words, the width dimension L30 between the side plate portions 10c and 10d of the base member 10 is approximately six times the width dimension L5 of the top plate 20. Strictly speaking, the width dimension L30 of the base member 10 is equal to the total length of the width of six tabletops 20, the gap between adjacent load detection units 11, 11, the gap between the right-most load detection unit 11 and the side plate portion 10c of the base member 10, and the gap between the left-most load detection unit 11 and the side plate portion 10d of the base member 10.

As shown in FIG. 10(b), the support member 22 is fixed to the base member 10 by inserting the protrusion 22b into the slit 17f of the base member 10 and threading the screw N1 into the connection hole 22d and through hole 10f that are aligned vertically. At this time, the load detection sensor 21 is positioned so as to overlap the slit 17f and through hole 10f of the base member 10 in the front-rear direction when viewed from above. That is, each load detection unit 11 is attached to the base member 10 using one slit 17f and one through hole 10f.

10(c), each notch groove 14a and each step 14b of the partition fixing plate 14 and each notch groove 15a and step 15b of the partition fixing plate 15 are arranged in a position overlapping in the front-rear direction with the gap between the adjacent load detection units 11, 11, the gap between the right end load detection unit 11 and the side plate portion 10c of the base member 10, and the gap between the left end load detection unit 11 and the side plate portion 10d of the base member 10. The partition members 16, 16, ... are installed between the notch grooves 14a and 15a corresponding to the front and rear, and between the step portions 14b and 15b. That is, the space Z1 on the top plate 20 of each load detection unit 11 is partitioned in the left-right direction by the partition members 16, 16 attached to the base member 10. The partition members 16, 16 at both the left and right ends of the display shelf section 3A are inserted into the upward U-shaped recesses formed by the steps 14b, 15b and the side plates 10c, 10d of the base member 10.

Next, we will explain the display shelf section 3B that is actually configured using only the load detection unit 110 with reference to FIG. 11.

11(a), the display shelf section 3B constructed using only the load detection units 110 allows three load detection units 110, 110, ... to be evenly arranged in the width direction of the base member 10. A gap of width L14 is formed between adjacent load detection units 110, 110, and a gap of width L14 is formed between the load detection units 110, 110 at both the left and right ends and the side plate portions 10c, 10d of the base member 10. In other words, the width dimension L30 between the side plate portions 10c and 10d of the base member 10 is approximately three times the width dimension L9 of the top plate 200. Strictly speaking, the width dimension L30 of the base member 10 is equal to the combined length of the width of three tabletops 200, the gap between adjacent load detection units 110, 110, the gap between the right-most load detection unit 11 and the side plate portion 10c of the base member 10, and the gap between the left-most load detection unit 11 and the side plate portion 10d of the base member 10.

As shown in FIG. 11(b), the support member 220 is fixed to the base member 10 by inserting the convex portions 220b, 220b across the adjacent slits 17f, 17f, and by inserting the screw N1 into the connection holes 220d, 220d and the through holes 10f, 10f that are aligned vertically. At this time, the load detection sensor 21 is disposed at the center position of the adjacent slits 17f, 17f when viewed from above. In other words, each load detection unit 11 is attached to the base member 10 using two slits 17f and two through holes 10f.

The width dimension L9 of the top plate 200 of the load detection unit 110 is equal to the sum of the width dimension of two top plates 20 of the load detection unit 11 and the width dimension L14 of the gap formed between adjacent load detection units 11, 11. In other words, two types of load detection units 11 and 110 can be attached interchangeably to the base member 10.

As shown in FIG. 11(c), the partition members 16, 16, ... are installed across the notch grooves 14a and 15a that overlap in the front-rear direction with respect to the gaps between adjacent load detection units 110, 110, the gap between the right-end load detection unit 110 and the side plate portion 10c of the base member 10, and the gap between the left-end load detection unit 110 and the side plate portion 10d of the base member 10. In other words, the space Z2 above the top plate 200 of each load detection unit 110 is partitioned in the left-right direction by the partition members 16, 16 attached to the base member 10.

Next, an example of a display shelf section 3C that is actually configured using a load detection unit 11 and a load detection unit 110 will be described with reference to FIG. 12.

As shown in Figures 12(a) and (b), the display shelf section 3C of this embodiment is configured using two load detection units 11 and two load detection units 110. Specifically, from the left side to the right side of the display shelf section 3C, the load detection units 110, 11, 110, and 11 are arranged in this order. In addition, a gap of width L14 is formed between adjacent load detection units 11 and 110.

As shown in FIG. 12(c), the partition members 16, 16, ... are installed across the notch grooves 14a and 15a that overlap in the front-rear direction with respect to the gap between adjacent load detection units 11, 110, the gap between the right-end load detection unit 11 and the side plate portion 10c of the base member 10, and the gap between the left-end load detection unit 110 and the side plate portion 10d of the base member 10.

As described above, the display shelf section 3 of this embodiment has a top plate 20 having a width dimension L5 and a top plate 200 having a width dimension L9, and the load detection sensor 21 is attached to the support member 22 or the support member 220 that is installed so that the widthwise position can be changed relative to the base member 10. This allows the support member 22 or the support member 220 to be moved in the width direction of the base member 10 to change the positions of the load detection sensor 21 and the top plate 20 or the top plate 200, so that top plates 20 and 200 with different widths can be combined and arranged on the base member 10. In other words, while enabling load detection by the load detection sensor 21, the size and arrangement position of the space Z1 on the top plate 20 and the space Z2 on the top plate 200 on which the items are placed can be changed, so that the layout of the items can be freely changed according to the size and type of the items, sales situation, sales time period, campaign, etc.

The width dimension L9 of the top plate 200 is approximately twice the width dimension L5 of the top plate 20. The width dimension L30 of the base member 10 is approximately six times the width dimension L5 of the top plate 20 (approximately three times the width dimension L9 of the top plate 200). In other words, the width dimension L9 of the top plate 200 and the width dimension L30 of the base member 10 are natural number multiples of the minimum width dimension L5 of the top plate 20, so that when the top plate 20 and the top plate 200 are arranged on the base member 10, it is possible to prevent the formation of a portion on the base member 10 where the top plate 20 or the top plate 200 is not arranged, i.e., a dead space, and it is possible to ensure a wide space Z1 and space Z2, which are the item placement areas.

The base member 10 is box-shaped and opens upward. Specifically, the front plate 10b, side plate 10c, 10d, and back plate 10e are erected on the periphery of the bottom plate 10a of the base member 10, and the load detection unit 11, 110 is stored inside the front plate 10b, side plate 10c, 10d, and back plate 10e. This makes it easy to install the load detection unit 11, 110 using the front plate 10b, side plate 10c, 10d, and back plate 10e as a guide, and the load detection unit 11 or the load detection unit 110 can be handled in a state where it is assembled to the base member 10 (a state where the display shelf section 3 is configured). For example, the display shelf section 3 can be easily carried and attached/detached to/from the brackets 7, 7. The display shelf section 3 can also be removed from the brackets 7, 7 to change the layout of the load detection unit 11 or the load detection unit 110 relative to the base member 10. In addition, the connectors of the multiple wiring 30 extending from the control unit 13 are arranged on the upper surface side of the bottom plate portion 10a through the slits 10g, so that wiring work when changing the layout of the load detection unit 11 or the load detection unit 110 can be easily performed on the upper surface side of the bottom plate portion 10a.

In addition, the sides of the load detection unit 11 or the load detection unit 110 are surrounded by the front plate 10b, the side plates 10c and 10d, and the back plate 10e of the base member 10, so the load detection sensor 21 is not exposed from the side, and it looks good. In addition, the strength of the bottom plate 10a that supports the load detection unit 11 or the load detection unit 110 is increased by the front plate 10b, the side plates 10c and 10d, and the back plate 10e, so the load detection units 11 and 110 can be stably supported.

In addition, the base member 10 has slits 17f, 17f, ... equally spaced in the width direction, and the support member 22 or the support member 220 can be reliably positioned in the width direction of the base member 10 by inserting the convex portion 22b of the support member 22 or the convex portion 220b, 220b of the support member 220 into any slit 17f. In addition, by inserting the convex portion 22b of the support member 22 or the convex portion 220b, 220b of the support member 220 into any slit 17f, the rotation of the support member 22 or the support member 220 about the vertical axis is restricted, and the connection hole 22d of the support member 22 or the connection hole 220d of the support member 220 can be positioned with the through hole 10f of the bottom plate portion 10a, so that the fixing work between the base member 10 and the support member 22 or the support member 220 can be easily performed.

As shown in FIG. 13(a), ribs 20b, 20b extending downward are provided on both sides of the tabletop 20. As a result, even if the right end of the left tabletop 20 is tilted downward due to the weight balance of the items, etc., as shown in FIG. 13(b), the rib 20b of the right tabletop 20 prevents items from being pinched vertically between the tabletop portion 20a of the left tabletop 20 and the tabletop portion 20a of the right tabletop 20. It is also possible to prevent items from falling between the tabletop portion 20a of the left tabletop 20 and the tabletop portion 20a of the right tabletop 20. In addition, the ribs 20b, 20b of the tabletop 20 improve the structural strength, so the tabletop 20 can be made thinner. Note that in FIG. 13(b), the inclination is shown to be greater than it actually is for the sake of convenience.

In addition, a partition member 16 is disposed between adjacent top plates 20, 20, preventing items from being placed across the adjacent top plates 20, 20.

In addition, the metal piece 21a extending in the front-rear direction in the load detection sensor 21 is arranged along the longitudinal direction of the top plate 20, which extends long in the front-rear direction, so that when an item is put in or taken out from the front side, distortion occurs efficiently in the metal piece 21a, and load detection can be performed accurately. Furthermore, as described above, the top plate 20 is connected to the metal piece 21a at a position forward of the center line C1 passing through the center of the front-rear of the top plate 20, and the support member 22 is connected to the metal piece 21a at a position rearward of the center line C1. In this way, since items are put in or taken out from the front side in the space Z1, the front end of the top plate 20 rotates up and down with a position rearward of the center line C1 as a fulcrum, and the metal piece 21a of the load detection sensor 21 can be efficiently distorted, so that the load detection sensor 21 can perform load detection with high accuracy.

In addition, the load detection sensor 21 is attached to the underside of the top plate 20 or top plate 200 via the reinforcing plate 20c or reinforcing plate 200c, and is attached to the bottom plate portion 10a of the base member 10 via the support member 22 or support member 220, so that the top plate 20, top plate 200, and bottom plate portion 10a of the base member 10 can be formed thin while maintaining their strength.

Next, the article holder and fixture of Example 2 will be described with reference to Figures 14 to 17. Note that descriptions of configurations that are the same as those of Example 1 will be omitted.

As shown in Figures 14 and 16, in the second embodiment of the present invention, the load detection unit 311 is mainly composed of a top plate 320 on which an object can be placed, a load detection sensor 21 connected to the underside of the top plate 320, a rectangular support member 322 fixed to the bottom plate portion 10a of the base member 10 and supporting the load detection sensor 21, and a pair of left and right partition members 316, 316 attached to the upper surface of the top plate 320. The partition members 316, 316 are configured symmetrically to each other.

The top plate 320 has through holes 320e (see FIG. 16(a)) that penetrate in the vertical direction at each of the four corners of the top plate portion 320a.

The support member 322 is made of a metal plate and is generally rectangular when viewed from above, with connection holes 322d, 322d formed in the left-right center of both the front and rear ends. A female thread is formed on the inner peripheral surface of this connection hole 322d. For ease of explanation, detailed illustrations are omitted, but the base member 10 and the front reinforcing member 17 have multiple through holes 10f, 10f, ... and through holes 17g, 17g, ... formed in the left-right direction at positions corresponding to the connection hole 322d formed in the front end of the support member 322.

As shown in FIG. 16(b), the support member 322 is fixed to the base member 10 by inserting a screw N1 from below into the through holes 10f, 10f, through holes 17g, 18d, and connection holes 322d, 322d that are overlapped in the vertical direction at both the front and rear ends.

The partition member 316 is made of a translucent synthetic resin and includes a mounting plate portion 316a that is generally rectangular when viewed from above, a partition plate portion 316b that is pentagonal when viewed from the side and rises from one side end of the mounting plate portion 316a, a front restricting plate portion 316c that is rectangular when viewed from the front and rises from the front end of the mounting plate portion 316a, and a rear restricting plate portion 316d that is rectangular when viewed from the front and rises from the rear end of the mounting plate portion 316a. The height dimension of the front restricting plate portion 316c is smaller than the height dimension of the rear restricting plate portion 316d. The depth dimension of the partition member 316 is the same as the depth dimension of the top plate 320.

Mounting holes 316e, 316f are formed at both front and rear ends of the mounting plate portion 316a, aligned in the left-right direction and penetrating in the up-down direction. In this embodiment, the one formed on the partition plate portion 316b side is referred to as mounting hole 316e, and the one formed on the left-right opposite side of the partition plate portion 316b is referred to as mounting hole 316f.

The partition member 316 is fixed to the top plate 320 by pushing nylon push rivets R from above into the vertically overlapping through holes 320e and mounting holes 316e with the side ends of the mounting plate 316a aligned with the side ends of the top plate 320a on the upper surface of the top plate 320a.

In addition, when the display shelf section 3A is assembled, the space Z311 (item placement area) on the top plate 320 of each load detection unit 311 is partitioned in the left-right direction by a pair of left and right partition members 316, 316 (see FIG. 16(c)). In detail, the space Z311 on the top plate 320 of the load detection unit 311 is composed of a space above the upper surface of the top plate portion 320a of the top plate 320 and a space above the upper surfaces of the mounting plate portions 316a, 316a of the partition members 316, 316 fixed to the left and right ends of the top plate 320. In addition, the width dimension L311 of the space Z311 is the shortest dimension between the inner surfaces of the partition plate portions 316b of the pair of partition members 316, and is the dimension obtained by subtracting the plate thickness dimension of the partition plate portion 316b of each partition member 316 from the width dimension L5 of the top plate 320 (see FIG. 16(a)).

Next, the load detection unit 411 shown in FIG. 15 and FIG. 17 will be described. The load detection unit 411 is different in size from the load detection unit 311 shown in FIG. 14 and FIG. 16. Specifically, the load detection unit 411 is fixed to the top plate 320 by pushing a push rivet R from above into the through hole 320e and the mounting hole 316f that are overlapped in the vertical direction, with the pair of left and right partition members 316, 316 protruding in the left and right directions from both ends of the top plate portion 320a on the upper surface of the top plate portion 320a. Note that the top plate 320, the load detection sensor 21, the support member 322, and the partition members 316, 316 used in the load detection unit 411 are the same as those in the load detection unit 311, so their description will be omitted.

In addition, when the display shelf section 3A is assembled, the space Z411 (item placement area) on the top plate 320 of each load detection unit 411 is partitioned in the left-right direction by a pair of left and right partition members 316, 316 (see FIG. 17(c)). In detail, the space Z411 on the top plate 320 of the load detection unit 311 is composed of the space above the upper surface of the top plate portion 320a of the top plate 320 and the space above the upper surfaces of the mounting plate portions 316a, 316a of the partition members 316, 316 fixed to the left and right ends of the top plate 320. The width dimension L411 of the space Z411 is the shortest dimension between the inner surfaces of the partition plate portions 316b of the pair of partition members 316, and is the sum of the width dimension L5 of the top plate 320 and the width dimensions of the protruding portions of the partition members 316, 316 that protrude in the left and right directions from both side ends of the top plate portion 320a, minus the plate thickness dimension of the partition plate portions 316b of each partition member 316. In other words, the width dimension L411 of the space Z411 on the top plate 320 of the load detection unit 411 is larger than the width dimension L311 of the space Z311 on the top plate 320 of the load detection unit 311 (L411>L311).

Next, we will explain the display shelf section 3A that is actually configured using only the load detection unit 311 with reference to Figure 16.

As shown in FIG. 16, the display shelf section 3A constructed using only the load detection units 311 is designed to allow six load detection units 311, 311, ... to be evenly arranged in the width direction of the base member 10. In addition, a gap of width L14 is formed between adjacent load detection units 311, 311, and a gap of width L14 is formed between the load detection units 311, 311 at both the left and right ends and the side plate sections 10c, 10d of the base member 10.

Next, we will explain the display shelf section 3A that is actually configured using only the load detection unit 411 with reference to Figure 17.

As shown in FIG. 17, the display shelf section 3A constructed using only the load detection units 411 is designed to allow five load detection units 411, 411, ... to be evenly arranged in the width direction of the base member 10. In addition, a gap of width L14 is formed between adjacent load detection units 411, 411, and a gap of width L14 is formed between the load detection units 411, 411 at both the left and right ends and the side plate sections 10c, 10d of the base member 10.

In this embodiment, in order to accommodate both cases where six load detection units 311, 311, ... are evenly arranged in the width direction of the base member 10 and where five load detection units 411, 411, ... are evenly arranged, the base member 10 and the front and rear reinforcing members 17, 18 are each provided with a plurality of through holes 10f, 10f, ... and through holes 18d, 18d, ... at appropriate positions in the left-right direction.

As shown in Figures 16 and 17, the load detection units are not limited to being arranged evenly across the width of the base member 10, but may be arranged in combination with load detection units 311, 411 of different sizes, and the widths of the gaps between adjacent load detection units and the gaps between the load detection units at both the left and right ends and the side plate portions 10c, 10d of the base member 10 do not have to be the same. Needless to say, the number and arrangement of the through holes 10f, 10f, ... and through holes 18d, 18d, ... formed in the base member 10 and the front and rear reinforcing members 17, 18 may be changed as appropriate to match the arrangement of the load detection units.

As described above, in the display shelf section 3 of this embodiment, the space Z311, Z411 as the article placement area on the top plate 320 is configured with different width dimensions by the top plate 320 and the partition members 316, 316 attached to the top plate 320, and the load detection sensor 21 is attached to the support member 322 that is installed so that the widthwise position can be changed relative to the base member 10. With this, the support member 322 can be moved in the width direction of the base member 10 to change the position of the load detection sensor 21 and the top plate 320, so that the load detection units 311, 411 with different width dimensions of the article placement area formed by the top plate 320 and the partition members 316, 316 can be combined and arranged on the base member 10. In other words, while enabling load detection by the load detection sensor 21, the size and placement position of the space Z311, Z411 on the top plate 320 where the article is placed can be changed, so that the layout of the articles can be freely changed according to the size and type of the article, sales situation, sales time period, campaign, etc.

The width of the spaces Z311, Z411 on the top plate 320 as the item placement area can be adjusted by changing the attachment positions of the partition members 316, 316 in the width direction relative to the top plate 320. This allows the width of the item placement area to be changed using the same top plate 320 and partition members 316, 316, so the layout of the items can be freely changed with a small number of parts.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention also includes modifications and additions that do not deviate from the gist of the present invention.

For example, in the first embodiment, the display shelf section 3 is illustrated as having two types of top plates 20 and 200 with different width dimensions, but this is not limited thereto, and the display shelf section 3 may have three or more types of top plates with different width dimensions.

In addition, in the above-mentioned Example 1, the load detection unit 11 and the load detection unit 110 are respectively provided with the support member 22 and the support member 220 having different width dimensions, but the support members may be of the same shape as long as the widthwise position can be changed relative to the base member.

In the above-mentioned first embodiment, the convex portion 22b of the support member 22 or the convex portion 220b of the support member 220 is inserted into any one of the through holes 10f, 10f, ... provided in the width direction of the base member 10 to change the width direction position of the load detection unit 11 and the load detection unit 110 relative to the base member 10, but this is not limiting. For example, the base member may be provided with a rail extending in the width direction, and the support member may be movably attached to the rail, so that the support member can be fixed at any position on the rail.

In addition, in the above-mentioned second embodiment, an embodiment was exemplified in which the width dimension of the item placement area can be changed to two types by changing the mounting positions of the partition members 316, 316 in the width direction relative to the top plate 320, but this is not limited thereto, and the width dimension of the item placement area can be changed to three or more types by increasing the number of mounting holes formed side by side in the left-right direction on the mounting plate portion of the partition member.

In addition, in the above-mentioned second embodiment, a through hole 320e is formed at each of the four corners of the top plate portion 320a of the top plate 320, and multiple mounting holes 316e, 316f are formed side by side in the left-right direction in the mounting plate portion 316a of the partition member 316. However, this is not limited to the above. By forming one mounting hole in the mounting plate portion of the partition member and forming multiple through holes side by side in the left-right direction at each of the four corners of the top plate portion of the top plate, the mounting position of the partition member in the width direction relative to the top plate can be changed to change the width dimension of the item placement area.

In the above-mentioned second embodiment, the partition member 316 is fixed to the top plate 320 by pushing the push rivet R from above into the through hole 320e and the mounting holes 316e, 316f that are superimposed in the vertical direction with the mounting plate portion 316a placed on the upper surface of the top plate portion 320a, but this is not limited thereto, and the top plate and the partition member may be fixed, for example, by bolting or engaging claws.

In addition, in the above-mentioned first and second embodiments, one load detection sensor 21 is attached to one tabletop, but this is not limited thereto, and multiple load detection sensors may be attached to one tabletop, and the load on the tabletop may be detected by the multiple load detection sensors. This is particularly useful when the tabletop is large in size, as it can be stably supported by multiple load detection sensors.

In addition, in the above-mentioned first and second embodiments, the fixture 1 is not limited to a product display shelf in which the display shelf section 3 is placed on a pair of left and right brackets 7, 7, but may be, for example, a product display stand in which the display shelf section 3 is placed on a stand.
