Description

  The present invention relates to a merchandise display device in which display shelves for displaying merchandise are stacked in the upper and lower stages, and a joint structure that connects the display shelves.

  In stores such as convenience stores, various products are displayed on a product display device called a so-called fixture.

  Of the various products, tobacco products, in particular, are qualified for purchasers, and since many types of brands are offered, they are displayed in an orderly manner, such as around electronic cash registers, where sales staff can reach them. It is demanded. Specifically, there is a product display device (hereinafter sometimes referred to as a “cigarette fixture”) for displaying tobacco products on the cashier counter (so-called cash register) or on the salesperson's work space (so-called cash register back). It is common to be installed. “Tobacco products” here are not cigarettes that are smoked by consumers, but are generally rectangular parallelepiped packages that contain multiple cigarettes (individual items) and a plurality of cigarettes. Means a carton or parcel that contains the package.

  The space (area and height) in which a product display device can be installed in a store such as a convenience store is subject to various restrictions depending on the installation environment such as store area, seasonal product cycle and interference with other facilities. For this reason, it is desired that a product display device represented by a cigarette ware can be changed in various dimensions according to the space in which it can be installed.

  With regard to this type of technology, Patent Document 1 proposes a product display device (cigarette display system case) in which the opposing distance between the side plates changes by sliding the left and right tray halves each having a side plate and a bottom plate along the guide rail. Has been. In this product display device, the protrusions (joint protrusions) formed on the upper end of the side plate are inserted into the insertion holes formed on the lower end surface of the other side plate located on the upper side and bolted, thereby Display shelves are linked together.

  Patent Document 2 proposes a product display device (product display fixture) in which a pair of opposing side plates are connected by a connecting member. In this merchandise display device, the facing distance between the side plates can be changed by adding connecting members, which are fastened with bolts to the side plates, in the length direction. In addition, the upper and lower display shelves are connected by inserting a hook-shaped projection formed on the upper end of the side plate into an insertion hole (through hole) provided in another side plate located on the upper side. .

  From the standpoint of reducing the installation space of a product display device, it is required to make the side plate as thin as possible to increase the display efficiency of the product. Generally, a connection structure (hereinafter referred to as a joint structure) of upper and lower stages provided on the side plate is also required. Miniaturization is achieved. For this reason, the size of the joint structure is very small compared to the width of the entire apparatus, and the operation of connecting the upper and lower display shelves to each other requires caution.

  Since the product display device of Patent Document 1 is a method of connecting the upper and lower side plates by individually bolting the protrusions, the operation of changing the number of display shelves is extremely complicated. However, on the other hand, when bolting is not performed, there is a risk that the upper and lower stages are disconnected when the commodity display device is moved or during an earthquake.

  Moreover, in the product display device of Patent Document 2, it is necessary to insert the protrusions straight in the vertical direction with respect to the insertion hole from the state where the upper and lower side plates are accurately aligned in the width direction and the depth direction. This is because the product display device is a system in which the upper and lower stages are connected by frictionally inserting a bowl-shaped protrusion into the insertion hole, and thus the protrusion and the insertion hole are formed with a fitting size. Because. However, as described above, the side plates are made thin, and it is difficult to align the upper and lower side plates.

  In particular, in the product display devices of Patent Document 1 and Patent Document 2, the interval between the side plates is variable, the sliding length of the guide rail (Patent Document 1), and the tightening strength of the connecting member with respect to the side plate (Patent Document) By changing 2), the facing distance between the side plates varies slightly. For this reason, it is difficult in the first place to accurately align the opposing intervals of the side plates in the upper and lower stages. In addition, since it is necessary to align the upper and lower projections and the insertion holes, the display shelf connection operation is not easy.

  The present invention has been made in view of the above-described problems, and provides a joint structure capable of easily and reliably connecting upper and lower display shelves, and a product display device using the joint structure.

The product display device of the present invention is a product display device comprising a plurality of display shelves for displaying products respectively, and a joint structure that connects the display shelves arranged in the upper and lower stages, and the display shelves Are engaged with each other in the vertical direction, and the display shelves are movable in at least one intersecting direction with respect to the vertical direction, and the display shelves are closer to the vertical direction from the first state.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same reference numerals are given to the same components, and the description will be omitted as appropriate.
In the present embodiment, there are cases where the front-rear, left-right, up-down and up-down directions are defined and illustrated as shown. However, this is defined for convenience in order to simply explain the relative relationship of the components, and does not necessarily limit the direction of the product in which the present invention is manufactured or used.

<First embodiment>
FIG. 1 is a perspective view showing a product display device 10 of the present embodiment. FIG. 2 is an exploded perspective view of the joint structure 100, which is an enlarged view of a partial region indicated by a circle II in FIG. FIG. 3A is an explanatory view showing a first state of the joint structure 100, and FIG. 3B is an explanatory view showing a second state thereof.

First, the outline | summary of the goods display apparatus 10 of this embodiment is demonstrated.
The product display device 10 connects a plurality of display shelves 20 (first shelf 20a, second shelf 20b, and third shelf 20c) for displaying products, and these display shelves 20 arranged on the upper and lower stages to each other. A joint structure 100.
The joint structure 100 includes a first portion 110 and a second portion 120 that are respectively provided on an upper display shelf (for example, the third shelf 20c) and a lower display shelf (for example, the second shelf 20b). By making transition from one state to the second state, the vertical coupling force between the first portion 110 and the second portion 120 is increased.
In the first state shown in FIG. 3A, display shelves (for example, the third shelf 20c and the second shelf 20b) are engaged with each other in the vertical direction, and at least one intersecting direction with respect to the vertical direction (for example, These display shelves are movable in the depth direction).
The second state shown in FIG. 3B is a state in which these display shelves (for example, the third shelf 20c and the second shelf 20b) are connected to each other closer to each other in the vertical direction from the first state.
And the merchandise display apparatus 10 of this embodiment can change to said 1st state and 2nd state freely.

  Here, the transition from the first state to the second state increases the coupling force in the vertical direction between the first portion 110 and the second portion 120 of the joint structure 100. In the second state, the first portion 110 and the second portion 120 are engaged at least in the vertical direction with a predetermined coupling force, and the vertical coupling force is greater in the second state than in the first state. Means big. When transitioning from the first state to the second state, it is optional whether the binding force increases continuously or stepwise, and may include a state where it may increase monotonously or temporarily decrease. Good. Further, in the present embodiment, the engagement between the first portion 110 and the second portion 120 refers to a state in which both are connected directly or indirectly and exert a mechanical or magnetic coupling force.

  Here, since the product display device of Patent Document 1 is a system in which the side plates are bolted together with the upper display shelf placed on the lower stage, the first state and the second state do not exist. In the product display device of Patent Document 2, the first state does not exist because the relative position between the display shelves can no longer be finely adjusted in the connected state in which the protrusion is inserted into the insertion hole and the coupling force is expressed. . On the other hand, according to the product display device 10 of the present embodiment, the relative position between the upper and lower display shelves 20 can be finely adjusted in the first state in the initial stage of engagement, so that the upper display shelves can be adjusted with a predetermined coupling force. The upper and lower stages can be accurately aligned in a state where 20 (third shelf 20c) is temporarily fastened to prevent the dropout. From this state, the coupling force can be increased to a second state in which the display shelves 20 are connected in the vertical direction, so that a reliable connection operation is possible.

  Hereinafter, in the present embodiment, a case where the binding force to one member or part (specifically, the protrusion 116) is increased by transitioning from the first state to the second state is exemplified. Not limited. As in a third embodiment to be described later, the coupling force may be obtained at a plurality of locations in the set of joint structures 100.

  The product display device 10 and the joint structure 100 of this embodiment will be described in detail.

  The product display device 10 of the present embodiment is a tobacco fixture. A merchandise display apparatus 10 shown in FIG. 1 is formed by connecting a plurality of stages of display shelves 20 in a vertically stacked manner. The display shelves 20 may be stacked and connected vertically upward, or may be stacked and connected obliquely upward by retreating each stage by a predetermined pitch in the depth direction. In addition, in FIG. 1, the state which isolate | separated the uppermost display shelf 20 (3rd shelf 20c) upward from the lower stage (2nd shelf 20b) for illustration is shown.

  One or a plurality of magazines MG are supported on the display shelves 20 of each stage. The magazine MG is a case for displaying a plurality (about 15 at the maximum) of tobacco products CP arranged in the front-rear direction (depth direction). The display shelf 20 of this embodiment supports a plurality of magazines MG arranged in the width direction. The magazine MG may include a forward feed mechanism (not shown) that urges the tobacco product CP from the rear in the depth direction toward the front. Thus, the tobacco product CP can be taken out from the foremost position of the magazine MG, which is the front surface of the product display device 10, regardless of the remaining number of tobacco products CP in the magazine MG.

  Hereinafter, in all the embodiments, the number of magazines MG supported on the display shelves 20 of each stage is not particularly limited. Although FIG. 1 shows a display shelf 20 that can support three magazines MG arranged in the width direction, this number is arbitrary. Further, the number of display shelves 20 connected in multiple stages is not particularly limited. In FIG. 1, a three-stage display shelf 20 is shown as an example, but it may be, for example, five or six stages.

  The display shelf 20 of the present embodiment includes a support member 30 that supports the magazine MG, and a pair of side plates (a left side plate 21 and a right side plate 22) provided to face both sides of the support member 30. The facing distance between the side plates (the left side plate 21 and the right side plate 22) is variable. As a result, the number of magazines MG supported side by side on the display shelves 20 of each stage can be changed from four to six.

  The structure in which the facing distance between the left side plate 21 and the right side plate 22 is variable is not particularly limited. In the display shelf 20 of the present embodiment, the support member 30 is composed of a double pipe of slidable pipes 31 and 32, and the length of the overlap of the pipes 31 and 32 is changed to change the length of the support member 30. The total length can be changed from long to short. Both ends of the support member 30 are fixed to the left side plate 21 and the right side plate 22, respectively. The left side plate 21 and the right side plate 22 are connected by a plurality of support members 30 arranged at the same height in the depth direction. By similarly changing the overall length of the plurality of support members 30, the facing interval changes to a large or small size while the left side plate 21 and the right side plate 22 face each other in parallel. Then, by setting the facing interval to an integral multiple of the width dimension of the magazine MG, the integer number of magazines MG can be supported between the left side plate 21 and the right side plate 22.

  In the commodity display device 10 of the present embodiment, the number and shape of the side plates and the shape, structure and quantity of the support member 30 are arbitrary. As shown in FIG. 1, only one side plate may be disposed at each end of the display shelf 20 in the width direction, or a third or fourth side plate (intermediate plate) is interposed between the left side plate 21 and the right side plate 22. ) May be erected.

  The joint structure 100 is a structure for connecting the display shelves 20 in multiple stages in the vertical direction. A first portion 110 is provided on one of the display shelves 20 to be connected, and a second portion 120 is provided on the other to be connected to each other. Either the first part 110 or the second part 120 may be the upper side. In FIG. 1, the first portion 110 protrudes downward from the left side plate 21 and the right side plate 22 of the upper display shelf 20, and the second portion 120 that receives the first portion 110 is formed on the left side plate 21 and the right side plate 22 of the lower display shelf 20. A state in which an opening is formed on the upper surface is illustrated. However, this aspect is an example. Instead of the present embodiment, the first portion 110 is formed so as to protrude from the upper surface of the side plates (the left side plate 21 and the right side plate 22) of the lower display shelf 20, and the second portion 120 is formed on the lower surface of the side plate of the upper display shelf 20. May be formed.

  In FIG. 1, as an example of the embodiment, a protrusion 116 is integrated as a first portion 110 on the lower end surfaces 24 b and 24 c of the side plates (21 b, 21 c and 22 b, 22 c) of the display shelf 20 excluding the lowermost first shelf 20 a. The formed embodiment is illustrated. Moreover, in the same figure, the case where the concave hole 126 is formed as the 2nd part 120 in the upper end surface (23b and 23c is shown in figure) of the side plates (21a-21c and 22a-22c) of all the display shelves 20 is shown. . Hereinafter, the case where the right side plate 22c of the third shelf 20c and the right side plate 22b of the second shelf 20b are connected will be described as an example. The connection between the other side plates is the same.

  As shown in FIG. 2, one of the first portion 110 and the second portion 120 (the first portion 110 in this embodiment) has a tapered protrusion 116 that becomes narrower toward the tip (lower end). . The protrusion 116 has a narrow width in the crossing direction (the depth direction in the present embodiment) with respect to the vertical insertion direction. The other of the first portion 110 and the second portion 120 (the second portion 120 in this embodiment) has a tapered concave hole 126 that becomes narrower in the intersecting direction (depth direction) toward the depth direction. doing. For convenience of explanation, in FIG. 2, the protrusion 116 is shown by a solid line, and the third shelf 20c is shown by a broken line.

  The protrusion 116 constituting the first portion 110 has a front end surface 111, a main surface 112, and a side end surface 113. As will be described later, a concave groove 115 is formed in the side end surface 113. The main surface 112 is a surface that expands in the depth direction, and the side end surface 113 is an end surface in the thickness direction of the protrusion 116. The base end 114 of the protrusion 116 is located on the lower end surface 24c of the third shelf 20c, and the front end surface 111 is located directly below the base end 114.

  The concave hole 126 constituting the second portion 120 is a concave portion surrounded by the bottom surface 121, the opening 124 and the peripheral wall surface (the main wall surface 122 and the side wall surface 123). As will be described later, a protrusion 125 is formed on the side wall surface 123. The opening 124 is formed in the upper end surface 23b of the second shelf 20b. The bottom surface 121 is located immediately below the opening 124.

The protrusion 116 and the recessed hole 126 have the same shape. The main surface 112 of the protrusion 116 has a tapered shape (trapezoidal shape) whose depth dimension decreases toward the distal end (lower end), that is, the depth dimension L2 of the base end (upper end) is larger than the depth dimension L1 of the distal end (lower end). Is also big. The thickness dimension W1 of the distal end surface 111 of the protrusion 116 and the thickness dimension W2 of the base end 114 are equal.
On the other hand, the main wall surface 122 of the recessed hole 126 has a tapered shape in which the depth dimension decreases from the opening 124 toward the bottom surface 121. That is, the depth dimension L4 of the opening 124 is larger than the depth dimension L3 of the bottom surface 121. The thickness dimension W4 of the opening 124 is equal to the thickness dimension W3 of the bottom surface 121.

  At least one of the first portion 110 or the second portion 120 is made of a flexible material. In the present embodiment, the first portion 110 (protruding portion 116) and the second portion 120 (concave hole 126), and the side plate (the right side plates 22c and 22b) formed integrally with these are ABS (Acrylonitrile-Butadiene-Styrene). Made of hard engineering plastic such as resin. Therefore, the protruding portion 116 and the peripheral wall surface of the recessed hole 126 are brought into frictional contact with each other by pressing the flexible protruding portion 116 against the peripheral wall surface of the recessed hole 126.

  The protrusion length H1 of the protrusion 116 is equal to the depth H2 of the concave hole 126 or slightly smaller than the depth H2. As a result, in the second state, the base end 114 of the projection 116 can be completely inserted into the concave hole 126. By completely inserting the protruding portion 116 into the recessed hole 126, the lower end surface 24c of the third shelf 20c and the upper end surface 23b of the second shelf 20b are in contact with each other. For this reason, the weight of the third shelf 20c and the mass of the tobacco product CP and the magazine MG can be supported not only on the joint structure 100 but also on the entire surface of the left side plate 21 and the right side plate 22.

  In the first state, a part of the protrusion 116 including the distal end surface 111 is inserted into the opening 124 of the recessed hole 126 (see FIG. 3A). The depth dimension L1 of the distal end surface 111 is sufficiently smaller than the depth dimension L4 of the opening 124. And the thickness dimension W1 of the front end surface 111 is the same as the thickness dimension W4 of the opening 124, or slightly larger. For this reason, by inserting the front end surface 111 into the opening 124, the main surface 112 of the protrusion 116 is brought into sliding contact or pressure contact with the main wall surface 122 of the opening 124 and receives a frictional force. Therefore, in the first state, a vertical coupling force is generated between the first portion 110 and the second portion 120.

  In the first state, the first portion 110 and the second portion 120 are loosely fitted to each other with a gap in the intersecting direction, and in the second state, the first portion 110 and the second portion 120 are press-fitted to each other. That is, in the first state, the main surface 112 of the protrusion 116 receives frictional force from the main wall surface 122 of the recessed hole 126, but at least one of the pair of side end surfaces 113 and the side wall surfaces 123 (FIG. 3A). Then, the right side end face 113 and the side wall face 123) are not in contact with each other. For this reason, relative movement in the depth direction is allowed between the third shelf 20c and the second shelf 20b. Thereby, as shown in FIG. 3A, the position in the depth direction of the third shelf 20c and the second shelf 20b frictionally engaged by the protrusion 116 in the first state is a predetermined length ΔD (however, Even if ΔD is shifted from each other by (L4-L1) or less), this positional shift can be removed by relatively moving the two. Since the main surface 112 and the main wall surface 122 of the present embodiment have the same tapered shape, only the protrusion 116 is inserted deeply into the concave hole 126 as shown by an arrow in FIG. The first portion 110 and the second portion 120 are automatically aligned (see FIG. 3B). As described above, in the product display device 10 of the present embodiment, the upper display shelf 20 (third shelf 20c) is replaced by the lower display shelf 20 (first display) without strictly aligning the display shelves 20 in the depth direction. The two are aligned at an appropriate relative position (hereinafter referred to as alignment adjustment) simply by pressing against the two shelves 20b).

  In the joint structure 100, the coupling force in the vertical direction between the first portion 110 and the second portion 120 increases by transitioning from the first state to the second state. In the case of this embodiment, the depth dimension L1 of the distal end surface 111 of the protrusion 116 is slightly larger than the depth dimension L3 of the bottom surface 121 of the recessed hole 126, and the depth dimension L2 of the base end 114 is larger than the depth dimension L4 of the opening 124. Slightly larger. Therefore, by setting the protrusion 116 to a predetermined depth or more, the pair of side end surfaces 113 of the protrusion 116 are pressed against the side wall surface 123 of the recessed hole 126 and closely contact each other in the depth direction. .

  That is, in the first state where the insertion depth of the protrusion 116 is shallow, a frictional force acts only on the main surface 112 of the protrusion 116, and the side end surface 113 in addition to the main surface 112 is increased by increasing the insertion depth of the protrusion 116. A frictional force is also generated. The frictional force applied to the side end face 113 is an internal force acting in the crossing direction between the first portion 110 and the second portion 120, and the alignment adjustment is performed between the third shelf 20c and the second shelf 20b by this internal force. . In the second state in which the protrusion 116 is completely inserted, the side end surface 113 is further pressed against the side wall surface 123. For this reason, the connecting force in the vertical direction applied to the first portion 110 (projection 116) continuously increases from the first state to the second state.

  That is, in the commodity display device 10 of the present embodiment, the internal force in the cross direction acting on the first portion 110 and the second portion 120 gradually increases as the display shelves 20 transition from the first state to the second state. And the shift | offset | difference of the position of the cross direction of the display shelves 20 in a 1st state reduces gradually.

  Hereinafter, the concave groove 115 formed in the side end face 113 will be described. 4A is a side view of the protruding portion 116 corresponding to the first portion 110, and FIG. 4B is a front view thereof. FIG. 4C is a plan view of the recessed hole 126 corresponding to the second portion 120.

  A concave groove 115 is formed in the side edge (side end surface 113) of at least one (both in the present embodiment) in the intersecting direction of the protruding portion 116 along the extending direction of the side edge. On the other hand, on the peripheral wall surface (side wall surface 123) of the recessed hole 126, a ridge 125 that engages with the recessed groove 115 is formed.

Thereby, especially in the second state, the protrusions 125 are fitted into the concave grooves 115 and are brought into close contact with each other, whereby the contact length between the protrusion 116 and the peripheral wall surface (the main wall surface 122, the side wall surface 123) of the concave hole 126 Becomes longer and the adhesion is increased. Further, by forming a V-shaped concave groove 115 instead of a ridge on the side end surface 113 of the projection 116, the vicinity of the side end surface 113 of the projection 116 (first portion 110) with respect to the second portion 120. It is connected stably. As shown in FIG. 4C, in the vicinity of the side end face 113, the thickness direction component (F _{2) of the} diagonally outward pressing force applied from the ridge 125 of the recessed hole 126 to the recessed groove 115 of the protruding portion 116. _{This is because ⊥} ) opposes the pressing force (F ₁ ) applied inward from the main wall surface 122 of the recessed hole 126 to the main surface 112 of the projection 116.

As described above, the joint structure 100 of the present embodiment is a structure for connecting a plurality of display shelves 20 each displaying products in the upper and lower stages, and the upper display shelf 20 (third shelf 20c) and A first portion 110 and a second portion 120 are provided respectively on the lower display shelf 20 (second shelf 20b).
In the first state (see FIG. 3A) in the initial connection between the upper and lower display shelves 20, the first portion 110 and the second portion 120 are close to each other and engage with each other. At this time, the first portion 110 and the second portion 120 are movable relative to each other in at least one intersecting direction with respect to the vertical direction. Further, in the second state (see FIG. 3B) corresponding to the end of connection between the upper and lower display shelves 20, the first portion 110 and the second portion 120 are closer to each other in the vertical direction from the first state. It becomes a connected state. And the joint structure 100 of this embodiment changes the coupling force of the up-down direction of the 1st part 110 and the 2nd part 120 by changing from a 1st state to a 2nd state.

  As a result, in the first state, the first portion 110 and the second portion 120 are engaged with each other with a predetermined coupling force to restrict the separation of the upper and lower display shelves 20 between the first portion 110 and the second portion 120. The alignment state can be confirmed. In the first state, the first portion 110 and the second portion 120 can be moved relative to each other in the intersecting direction (for example, the depth direction). Therefore, when the alignment accuracy is not sufficient, the relative position between the two is finely adjusted. be able to. In addition, the first portion 110 and the second portion 120 are further moved closer to each other in the vertical direction to increase the coupling force, thereby connecting the first portion 110 and the second portion 120 (second state). For this reason, when connecting the display shelves 20 in which the first part 110 and the second part 120 are arranged in the upper and lower stages to each other, the upper display shelf 20 is simply pushed down toward the lower display shelf 20. Can be accurately connected.

Various modifications are allowed for this embodiment.
5A is a side view of the protrusion 116 of the first portion 110 according to a modification of the present embodiment, FIG. 5B is a front view thereof, and FIG. 5C is a recessed hole of the second portion 120. 126 is a plan view of 126. FIG.

The projecting portion 116 of this modification example becomes narrower in the third direction (width direction) perpendicular to the vertical direction and the intersecting direction (depth direction) from the base end 114 toward the tip (tip surface 111). This is different from the first embodiment (see FIGS. 4A and 4B). In other words, the protrusions 116 of the present modification are each formed in a tapered shape in the depth direction and the width direction of the product display device 10.
In the joint structure 100 according to the present modification, the first portion 110 and the second portion 120 are loosely fitted to each other with a gap in the third direction (width direction) in the first state. In the second state, the first portion 110 and the second portion 120 are in close contact with each other in the third direction (width direction).

  With this configuration, the joint structure 100 of the present modification automatically moves not only in the intersecting direction (depth direction) but also in the third direction (width direction) by bringing the first portion 110 and the second portion 120 close to each other in the vertical direction. The alignment can be adjusted automatically.

  Further, since the front end surface 111 of the protrusion 116 can be loosely inserted in the depth direction and the width direction with respect to the opening 124 of the recessed hole 126, the upper third shelf 20c can be inserted into the lower second shelf 20b. Therefore, it is not necessary to precisely align the two directions. Only by loosely inserting the front end surface 111 of the protruding portion 116 into the opening 124, the protruding portion 116 is inserted into the concave hole 126 to a predetermined depth by its own weight of the third shelf 20c and is in a first state in which the protruding portion 116 is frictionally engaged with each other. . And also in the joint structure 100 of this modification, the protrusion part 116 is press-fitted by further inserting the protrusion part 116 deeply into the recessed hole 126 from this first state. Thereby, the connection force of both the up-and-down direction increases, it changes to the 2nd state, and it will be in the state where the 3rd shelf 20c and the 2nd shelf 20b were connected firmly.

  As another modification of the present embodiment, the groove depth of the concave groove 115 and the convex height of the ridge 125 may be changed. As described above, in the joint structure 100 of the present embodiment, the groove depth of the concave groove 115 and the convex height of the ridge 125 are constant in the extending direction, but instead, the tip end The groove depth of the concave groove 115 in the vicinity of the surface 111 may be deeper than the groove depth in the vicinity of the base end 114. Similarly, the convex height of the ridge 125 near the bottom surface 121 may be made higher than the convex height near the opening 124. Thereby, in the first state, the low ridge 125 near the opening 124 does not come into contact with the deep groove 115 near the tip surface 111, and the groove 115 and the ridge 125 are formed in the vicinity of the second state. It will come into contact. Therefore, when aligning the display shelves 20 in the first state, the groove 115 and the ridge 125 are not in contact with each other, and the frictional force between the first portion 110 and the second portion 120 is not excessive. In the second state, the first part 110 and the second part 120 are in close pressure contact with each other.

  Moreover, although the said embodiment and the modification illustrated the case where the 1st part 110 and the 2nd part 120 which comprise the joint structure 100 were integrally formed in the side plate (the left side board 21 and the right side board 22) of the display shelf 20, The invention is not limited to this. The joint structure 100 may be manufactured as a separate member from the display shelf 20. In this case, the first portion 110 including the protruding portion 116 and the second portion 120 including the recessed hole 126 are formed in a block shape or a plate shape, respectively, and then the first portion 110 and the second portion 120 are displayed on the display shelf 20. It is good to fix to the upper part and the lower part of (for example, the left side plate 21 and the right side plate 22).

<Second embodiment>
FIG. 6 is a perspective view showing the commodity display device 10 according to the present embodiment. FIG. 7 is an exploded side view of the joint structure 100. The merchandise display device 10 of this embodiment is different from the first embodiment in that the display shelves 20 are connected to each other by using a magnetic attraction force.

  In the product display device 10 of the present embodiment, the first portion 110 and the second portion 120 are joined surfaces (lower end surfaces) between the display shelves 20 to be connected (hereinafter, the third shelf 20c and the second shelf 20b are exemplified). 24c and the upper end surface 23b), each of which includes a pair of permanent magnets that are magnetically attracted to each other, or a permanent magnet and a magnetic body. For explanation, FIG. 6 shows a state where the third shelf 20c and the second shelf 20b are separated.

  As shown in FIG. 6, brackets 130 are attached to the upper end surfaces (23b and 23c are shown) and the lower end surfaces (24c are shown) of the left side plate 21 and the right side plate 22 along the respective end surfaces. Hereinafter, the upper surface or the lower surface of the bracket 130 may be referred to as an upper end surface or a lower end surface of the side plates (the left side plate 21 and the right side plate 22). In the bracket 130 of the present embodiment, a plurality of permanent magnets or magnetic bodies are arranged at predetermined intervals along the longitudinal direction (depth direction).

  The lower end surface 24c of the upper third shelf 20c and the upper end surface 23b of the lower second shelf 20b receive an attractive force by the magnetic force between the pair of permanent magnets or the permanent magnet and the magnetic body. Hereinafter, the case where the attractive force of permanent magnets is used will be exemplified.

  As shown in FIG. 7, the joint structure 100 of the present embodiment includes a first permanent magnet 141 disposed on the bracket 130 on the lower end surface 24 c of the upper third shelf 20 c and an upper portion of the second shelf 20 b on the lower stage. And a second permanent magnet 142 disposed on the bracket 130 of the end surface 23b. The first permanent magnet 141 and the second permanent magnet 142 have opposite pole faces.

  Here, the permanent magnets (first permanent magnet 141, permanent magnet 142) are provided on the joint surfaces (lower end surface 24c, upper end surface 23b), as shown in FIG. In addition to the case where the magnetic field gradient is formed on the bonding surface, the case where the permanent magnet is included in the display shelf and the magnetic pole surface is not exposed from the bonding surface is included.

  One of the pair of permanent magnets, or one of the permanent magnet or the magnetic body is provided so as to protrude from the joining surface (lower end surface 24c or upper end surface 23b), and the other is provided on the joining surface (upper end surface 23b or lower end surface 24c). It is provided at the bottom of the formed recess 150. In this embodiment, the 2nd permanent magnet 142 protrudes from the upper end surface 23b, and the 1st permanent magnet 141 is accommodated in the bottomed inside of the recessed part 150 formed in the lower end surface 24c. The first portion 110 of the present embodiment includes a first permanent magnet 141 and a recess 150.

  The magnetic pole surface 144 of the second permanent magnet 142 and the magnetic pole surface 143 of the first permanent magnet 141 have different polarities. The magnetic pole surface 143 of the first permanent magnet 141 is located inside the recess 150, and the magnetic pole surfaces 143 and 144 are brought into close contact with each other by inserting the second permanent magnet 142 into the recess 150. The protruding height of the second permanent magnet 142 is equal to the depth from the lower end opening of the recess 150 to the magnetic pole surface 143.

  The hole diameter and shape of the recess 150 are equal to the outer diameter and shape of the second permanent magnet 142. For this reason, the second permanent magnet 142 can be inserted into the recess 150 in a fitting manner.

  The joint structure 100 of the present embodiment has a coupling force in the vertical direction in the first state in the initial stage of engagement, but can move in the crossing direction, and moves up and down by transitioning to the second state at the end of engagement. The binding force in the direction increases. The first state is a state where the first permanent magnet 141 and the second permanent magnet 142 are attracted by a magnetic force without the second permanent magnet 142 being inserted into the recess 150 as shown in FIG. is there. In the second state of the present embodiment, as shown in FIG. 8B, the second permanent magnet 142 is inserted into the recess 150 and receives a frictional force from the peripheral surface 151 of the recess 150, and the first permanent magnet 141. It is in a state adsorbed on

  In the first state, the lower end surface 24c and the upper end surface 23b are engaged in the vertical direction by the attractive force of the first permanent magnet 141 and the second permanent magnet 142. For this reason, even if the alignment of the first portion 110 and the second portion 120 is insufficient in some joint structures 100 in the commodity display device 10, the upper and lower display shelves 20 are caused by the suction force in the other joint structures 100. Withdrawal is regulated. The second permanent magnet 142 is inserted into the recess 150 after the joining surfaces of the upper and lower display shelves 20 are aligned with each other in the temporarily fastened state. As a result, the frictional force applied to the second permanent magnet 142 increases according to the insertion depth, and the attractive force of the second permanent magnet 142 is inversely proportional to the square of the distance between the magnetic pole surface 143 and the magnetic pole surface 144. It will increase. And the 2nd permanent magnet 142 and the 1st permanent magnet 141 will be in the 2nd state which closely_contact | adhered, and the upper and lower display shelves 20 will be firmly connected.

  In the joint structure 100 of the present embodiment, the second permanent magnet 142 becomes a shear pin (shear pin) by fitting the second permanent magnet 142 (second portion 120) into the recess 150 (see FIG. 7). . Thereby, the 3rd shelf 20c and the 2nd shelf 20b are mechanically connected by the surface direction (width direction of the goods display apparatus 10) of a side plate (the left side board 21 and the right side board 22). For this reason, the product display device 10 of the present embodiment can collectively change the facing interval between the left side plate 21 and the right side plate 22 in a state where the display shelves 20 are connected in multiple stages. .

  The joint structure 100 of the present embodiment transitions from the first state to the second state, so that the attractive force and shearing force of the second permanent magnet 142, that is, the cross direction acting on the first portion 110 and the second portion 120. Internal force increases. And in a 1st state, the position shift of a display shelf (the 3rd shelf 20c, the 2nd shelf 20b) can be finely adjusted suitably using the magnetic force of the 1st permanent magnet 141,142.

  In the present embodiment, the case where the second permanent magnet 142 is projected from the joint surface (upper end surface 23b) and used as a shear pin is exemplified. However, from the viewpoint of increasing the shear strength of the joint structure 100, the second permanent magnet 142 is used. Instead, a high-strength and ferromagnetic metal material such as iron may be used.

<Third embodiment>
FIG. 9 is an exploded side view illustrating the joint structure 100 according to the present embodiment. The merchandise display device 10 of this embodiment is common to the second embodiment in that the joining surfaces of the upper and lower display shelves 20 are engaged with each other using the magnetic force of the permanent magnet in the first state in the initial stage of engagement. In the product display device 10 according to the present embodiment, the joining surfaces of the upper and lower display shelves 20 are further suitably aligned. The merchandise display device 10 according to the present embodiment is the same as that of the second embodiment except for the joint structure 100, and is not illustrated.

  The joint structure 100 of this embodiment includes a vibrator 160. The vibrator 160 is attached with a permanent magnet or a magnetic material. Further, the vibrator 160 can swing with respect to the display shelf 20 in a direction intersecting with the vertical direction (for example, a depth direction). Specifically, the vibrator 160 attached with the first permanent magnet 141 and capable of swinging in the depth direction with respect to the third shelf 20c is accommodated in the recess 26 formed in the lower end surface 24c of the third shelf 20c. ing.

  The recess 26 is provided with an elastic member 162 that elastically couples the vibrator 160 to the third shelf 20c so as to be displaceable in the vertical direction and the crossing direction thereof. A first permanent magnet 141 is disposed on the lower surface of the vibrator 160. The magnetic pole surface 143 of the first permanent magnet 141 of the present embodiment is disposed at the same height (level) as the lower surface 163 of the vibrator 160. On the other hand, a second permanent magnet 142 is embedded in the upper end surface 23b of the second shelf 20b. The magnetic pole surface 144 of the second permanent magnet 142 is the same height as the upper end surface 23b. The opposing magnetic pole surfaces of the first permanent magnet 141 and the second permanent magnet 142 are different polarities.

  The diameter of the recess 26 is increased toward the lower end opening, and at least a part of the peripheral wall surface is inclined. The vibrator 160 is slidable along the inclined peripheral wall surface. That is, the vibrator 160 and the recess 26 are aligned by pushing the vibrator 160 into the recess 26. In the present embodiment, inclined surfaces 165 are provided at both edges of the upper surface 164 of the vibrator 160 in the depth direction. By sliding the inclined surface 165 with respect to the peripheral wall surface of the recess 26, the vibrator 160 can be aligned with a predetermined position in the depth direction with respect to the recess 26.

  FIG. 10 is an explanatory diagram showing a first state of the joint structure 100 of the present embodiment. FIG. 11 is an explanatory diagram showing the second state. In the first state shown in FIG. 10, the third shelf 20c and the second shelf 20b are displaced from each other by a predetermined length in the depth direction. In the joint structure 100 of the present embodiment, this misalignment is removed, and the third shelf 20c and the second shelf 20b are aligned.

  In the first state shown in FIG. 10, the vibrator 160 is magnetically coupled to the other display shelf (second shelf 20b) connected to the one display shelf (third shelf 20c) provided with the vibrator 160. Adsorb to. That is, according to the joint structure 100 of the present embodiment, the oscillator 160 oscillates both vertically before the third shelf 20c and the second shelf 20b are aligned because the oscillating oscillator 160 has a magnetic force. Combine. Then, as shown in FIG. 11, the display shelves 20 provided with the vibrators 160 are displayed when the display shelves (second shelf 20 b and third shelf 20 c) are further moved closer to each other in the vertical direction. The (third shelf 20c) and the vibrator 160 are aligned at a predetermined position in the crossing direction. This is because, as described above, the inclined surface 165 of the vibrator 160 slides with respect to the peripheral wall surface of the concave portion 26 so that both are aligned.

  Furthermore, the joint structure 100 of the present embodiment has an engaging means (a concave portion 171 and a convex portion 172 fitted thereto) for fixing these aligned display shelves (second shelf 20b, third shelf 20c). It has.

  In the joint structure 100 of the present embodiment, the vibrator 160 and the third shelf 20 c are elastically connected by the elastic member 162. For this reason, when the oscillating vibrator 160 is attracted to the second shelf 20b, the third shelf 20c is attracted to the second shelf 20b by the elastic restoring force of the elastic member 162, and both are aligned. That is, even if the third shelf 20c and the second shelf 20b are not accurately aligned, the vibrator 160 is swung by the first permanent magnet 141 and the second permanent magnet 142 being magnetically attracted. It is connected to a predetermined position on the two shelves 20b. In this state, since the third shelf 20c is not yet fixed to the second shelf 20b, the third shelf 20c is moved to the second shelf 20b by the elastic restoring force of the elastic member 162 and the sliding of the inclined surface 165 of the vibrator 160. It will be guided directly above and will be automatically aligned.

  That is, in the product display device 10 (see FIG. 6) of the present embodiment, the first permanent magnet 141 of the vibrator 160 is simply moved to the second permanent magnet 142 just by bringing the third shelf 20c close to the second shelf 20b. To the first state. Furthermore, the vibrator 160 of the present embodiment functions as an alignment pin for the third shelf 20c. By lowering (adjacent) the third shelf 20c toward the second shelf 20b from the first state, the recess 26 (that is, the third shelf 20c) slides with respect to the vibrator 160, and the third shelf 20c. Is displaced directly above the transducer 160 and the second shelf 20b. In this state, the concave portion 171 and the convex portion 172 are aligned, so that the vertical coupling force between the first portion 110 and the second portion 120 is increased by mechanically engaging the concave portion 171 and the convex portion 172 ( Second state: see FIG. 11).

  In the second state, the convex portion 172 inserted into the concave portion 171 becomes a shear pin (shear pin), and the third shelf 20c and the second shelf 20b are brought into a direction perpendicular to the side plate (the left side plate 21 and the right side plate 22) ( Mechanically connected in the width direction). Thereby, it is possible to collectively change the facing distance between the left side plate 21 and the right side plate 22 in all stages while the display shelves 20 are connected in multiple stages.

  In the above-described embodiment, the inclined surface 165 of the vibrator 160 is formed at the edges on both sides in the depth direction, but the present invention is not limited to this. In place of both sides in the depth direction or in addition to both sides in the depth direction, an inclined surface 165 may be formed on the edge of the upper surface 164 in the thickness direction (the width direction of the product display device 10) (not shown). ). Thereby, the vibrator 160 can be aligned at a predetermined position in the width direction with respect to the recess 26. That is, when the transition is made from the first state to the second state, the third shelf 20c and the second shelf 20b can be aligned in the width direction of the product display device 10.
