Description

DESCRIPTION FOLDING DISPLAY SHELF

Technical Field [0001]

The present invention relates to a flexible material display shelf which can be in a space-saving folded state when not in use.

Background Art [0002]

Conventionally, as means of securing a display space of manufactured goods at trade shows or increasing a display space of products at retail stores, assembly type display stands or display shelves are used in some cases.

[0003]

Regarding such assembly type display stands or display shelves, there are cases where dedicated display shelves are used to appeal features and design of products particularly when new products are displayed or arranged. Therefore, it is demanded that assembly type display stands or the display shelves are capable of displaying as many products as possible relative to a limited installation area and can be easily folded and carried (moreover, easily to reassemble) in the case of moving to another display place, sold-out of the product, etc.

[0004]

As an assembly type display stand or a display shelf, for example, Patent Literature 1 discloses a display stand having a plurality of product display surfaces and capable of displaying products in various forms in accordance with various installation situations. Patent Literature 2 also discloses a display stand which can be relatively easily assembled and folded and is capable of displaying a large number of products.

Summary of Invention Technical Problem [0006]

However, in the display stand according to Patent Literature 1, it is necessary to bond and fix (or to engage and fix) respective members at the time of assembly, and thus it was not easy to assemble and to fold. Moreover, in the display stand according to Patent Literature 2, it is necessary to fix a display surface by an engagement recessed part. Therefore, a display stand that can be assembled and folded more easily (quickly) is desired. Furthermore, in order to further improve the ease of arrangement or removal of articles and to improve design of the display shelf itself, it is desirable to reduce the proportion of members as much as possible, such as widening a takeout opening of the display shelf. In that case, however, in conventional display shelves, there are cases where resistance to a load applied to the display shelves or installation stability may be insufficient {For example, not only a load in the vertical direction (load generated by placing articles) but also a load from a side surface direction (impact load when colliding with another object) or the force in a twisting direction}.

[0007]

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a display shelf which can be easily assembled and folded and has high durability against a load and shock.

Description of Embodiments [0013]

Hereinafter, a display shelf according to the present embodiment and display shelves according to other embodiments will be described in detail with reference to the drawings.

[0014]

Here, in the present invention, in a display shelf capable of transitioning between a folded state and a deployed state, a columnar part is included as an auxiliary member, and at least a part of the columnar part is in a collapsed state in a cross section in the height direction of the display shelf when the display shelf is in the folded state, and is in an annular state or an expanded state in a cross section in the height direction of the display shelf when the display shelf is in the deployed state (installed state).

That is, a form of the columnar part can be changed as appropriate depending on the folded state or the deployed state of the display shelf (capable of transitioning between the collapsed state and the annular state or the expanded state). Hereinafter, specific structures of such a columnar part and a display shelf having the columnar part will be described. Note that the embodiments below are merely examples, and materials, bonding methods, an order of superposition, and the like of each member are not limited to the following embodiments. Moreover, the respective embodiments should not be understood in a limiting manner as being applied in a specific form but may be combined in any combination. For example, it should be understood that descriptions of an embodiment also apply to another embodiment. Moreover, even when a description and another description are described separately, it should be understood that a combination of the description and the other description is also described. Furthermore, information such as numerical values {for example, the number of display surfaces, the number of parts forming a display shelf, and the like} as specific examples illustrated in the following embodiments or modifications is merely an example, and thus it should be understood that they may be changed as appropriate as long as they do not greatly depart from the principles of the following embodiments or the modifications.

[0015] «First Embodiment»

First, referring to Figs. 1 to 3, an overall structure of a display shelf 1 according to a first embodiment will be described. Note that, in the present embodiment, the display shelf 1 has a structure symmetrical in the depth direction (front and rear) with a plate-shaped part 210 (described later) as a boundary (for example, shapes of a front upper stage display surface part 311 and a rear upper stage display surface part 312 are substantially the same), and therefore, in the case where an explanation is made on a front side of the display shelf 1 (for example, the front upper stage display surface part 311), it should be understood that the explanation of a rear side of the display shelf 1 (for example, the rear upper stage display surface part 312) is also made at the same time. On the other hand, as long as the display shelf 1 can be structured, it is not necessary to make shapes of the front side and the rear side of the display shelf 1 (for example, the front upper stage display surface part 311 and the rear upper stage display surface part 312) the same, and they may be different from each other. Similarly, in the present embodiment, the display shelf 1 has a symmetrical structure in the width direction (right and left) thereof; however, a structure of each part of the display shelf 1 can be appropriately changed as long as transition to a deployed state and a folded state can be performed by a mechanism similar to that of the display shelf 1 of the embodiment. Similarly, the height, the width, the depth, the shape of each part, the thickness of a member, and the like of the display shelf 1 can be appropriately changed.

[0016]

Fig. 1 is an overall view (perspective view) of the display shelf 1 according to the embodiment in a deployed state, and Fig. 2 is a top view of the display shelf 1.

[0017]

As illustrated in Fig. 1, the display shelf 1 according to the present embodiment includes the frame part 100 (the front frame part 110 and the rear frame part 120) structured to have a hexagonal tubular shape {tubular shape structured to have a substantially hexagonal shape in a planar view (or a horizontal cross section)} including takeout windows as appropriate. Inside the frame part 100, the display surface part 300 (the upper stage display surface part 310, the middle stage display surface part 320, and the lower stage display surface part 330) is provided in such a manner as to be connected to the frame part 100. Inside the frame part 100, a support part 200 is further provided in such a manner as to be connected to the display surface part 300 (upper stage display surface part 310, middle stage display surface part 320, and lower stage display surface part 330). The frame part 100 serves as a side wall of the display shelf 1, the display surface part 300 serves as a sub-floor for displaying articles, and the support part 200 serves as a support plate for supporting a load when articles are placed on the display surface part 300. In addition, the display surface part 300 forms a predetermined angle with respect to the plate-shaped part 210 {about 90 0 with respect to the height direction of the plate-shaped part in the present embodiment (an angle that becomes horizontal with respect to an installation surface)}; however, the angle is not particularly limited thereto.

[0018]

Next, more detailed structures of the frame part 100, the support part 200, and the display surface part 300 in the display shelf 1 according to the present embodiment will be described.

[0019]

As illustrated in Fig. 1 and Fig. 2, the frame part 100 according to the present embodiment has the front frame part 110 and the rear frame part 120. Furthermore, the front frame part 110 is bent along the left fold 114L and the right fold 114R included penetrating the front frame part 110 in the vertical direction, whereby the left front frame part 111, the middle front frame part 112, and the right front frame part 113 are formed. The rear frame part 120 is also bent like the front frame part 110 is, whereby a left rear frame part 121, a middle rear frame part 122, and a right rear frame part 123 are formed. Furthermore, the frame part 100 is formed by connecting the left front frame part 111 to the left rear frame part 121 and the right front frame part 113 to the right rear frame part 123. The front frame part 110 includes a middle stage takeout window 118 and a lower stage takeout window 119 which are windows for taking out articles for the display surface part 300 and an upper stage display frame part 115, a middle stage display frame part 116, and a lower stage display frame part 117 which form frame parts of the takeout windows (the rear frame part 120 also includes similar takeout windows and frame parts).

[0020]

The support part 200 provided inside the tube of the frame part 100 has the plate-shaped part 210 which is a plate-shaped member and secondary support columns 220 (left secondary support column 221 and right secondary support column 222) which are members of a tubular shape (in the present embodiment, a pentagonal tubular shape having an adhesive part with the plate-shaped part 210 at a part thereof) provided on both end parts of the plate-shaped part 210. In the present embodiment, the plate-shaped part 210 and the secondary support column 220 have substantially the same height and has a height from the installation surface of the display shelf 1 to the uppermost stage display surface (upper stage display surface part 310 which will be described later) of the display surface part 300.

[0021]

The display surface part 300 has the upper stage display surface part 310, the middle stage display surface part 320, and the lower stage display surface part 330 which are sub-floors for three stages. In addition, the upper stage display surface part 310 (middle stage display surface part 320 or lower stage display surface part 330) is divided into the front upper stage display surface part 311 (front middle stage display surface part 321 or front lower stage display surface part 331) and the rear upper stage display surface part 312 (rear middle stage display surface part 322 or rear lower stage display surface part 332) while interposing the plate-shaped part 210. The front upper stage display surface part 311 (the front middle stage display surface part 321 or the front lower stage display surface part 331) is connected to the upper stage display frame part 115 (the middle stage display frame part 116 or the lower stage display frame part 117) of the front frame part 110 at a front edge thereof and is connected to a front surface of the plate-shaped part 210 at a rear edge thereof. Similarly, the rear upper stage display surface part 312 (the rear middle stage display surface part 322 or the rear lower stage display surface part 332) is connected to a rear surface of the plate-shaped part 210 at a front edge thereof and is connected to the rear frame part 120 at a rear edge thereof. In this manner, the upper stage display surface part 310 (middle stage display surface part 320 or lower stage display surface part 330), which is a display surface on which articles can be displayed, is divided into the front and the rear into the front upper stage display surface part 311 and the rear upper stage display surface part 312 (the front middle stage display surface part 321 and the rear middle stage display surface part 322, or the front lower stage display surface part 331 and the rear lower stage display surface part 332). Upon folding and deploying, which will be described later, the display surface part 300 is folded with a connecting part with the plate-shaped part 210 as a starting point.

[0022]

As illustrated in Fig. 3, the plate-shaped part 210 has a middle stage support opening 211 and a lower stage support opening 212 which are openings corresponding to the middle stage takeout window 118 and the lower stage takeout window 119, respectively, included in the front frame part 110. As illustrated in Fig. 1, by forming the openings in the plate-shaped part 210, the aforementioned front middle stage display surface part 321 (the rear middle stage display surface part 322) and the front lower stage display surface part 331 (the rear lower stage display surface part 332) are connected (as a result, a larger article can be placed on the display surfaces; however, the plate-shaped part 210 may not include the openings). Note that, in the display shelf 1 according to the present embodiment, since the secondary support column 220 connected to the plate-shaped part 210 is included in the support part 200, a load applied to the plate-shaped part 210 is reduced, and as a result, the opening can be wider than that in the prior art (an area of the plate-shaped part 210 is further reduced).

[0023]

Here, with reference to Fig. 2, engagement relations between the frame part 100, the support part 200, and the display surface part 300 (upper stage display surface part 310) will be described in further detail. The front upper stage display surface part 311 (rear upper stage display surface part 312) is connected to the front frame part 110 (rear frame part 120) via a front display surface outer edge 311E (rear display surface outer edge 312E) and is connected to the plate-shaped part 210 via a front display surface inner edge 3111 (rear display surface inner edge 3121). Also, the left secondary support column 221 (right secondary support column 222) is in contact with the frame part 100 at a left support auxiliary surface 22IS (right support auxiliary surface 222S) which is a part of a surface forming the left secondary support column 221 (right secondary support column 222). Furthermore, between the upper stage display surface part 310 (the front upper stage display surface part 311 or the rear upper stage display surface part 312) and the frame part 100 (in the deployed state, between the frame part 100 and the upper stage display surface part 310), the secondary support column 220 (left secondary support column 221 and right secondary support column 222) includes openings (left display opening 315 and right display opening 316) which can penetrate in the height direction of the display shelf 1 {when the display shelf 1 is viewed from the height direction, the secondary support columns 220 (the left secondary support column 221 and the right secondary support column 222) can be seen (parts corresponding to hatched parts in Fig. 2). By providing such openings (the left display opening 315 and the right display opening 316), when the display shelf 1 transitions from the deployed state to the folded state (folding and deploying of the display shelf 1 will be described later), movement of the secondary support column 220 in the height direction becomes unlikely to be inhibited by the upper stage display surface part 310 {the upper stage display surface part 310 and the secondary support column 220 becomes unlikely to collide when the upper stage display surface part 310 is folded (folding with the front display surface inner edge 3111 and the rear display surface inner edge 3121 serving as an axis to allow the upper stage display surface part 310 to transition into a plate shape)}. Therefore, folding and deploying of the display shelf 1 can be further smoother. Note that in principle, the front display surface inner edge 3111, the front display surface outer edge 311E, the rear display surface inner edge 3121, the rear display surface outer edge 312E, and the like represent parts forming edges (a part being a line at a tip) of the upper stage display surface part 310 {for example, in the case where the upper stage display surface part 310 is formed by bending a certain member, a line as a folding place (polygonal line)}.

[0024]

As illustrated in Figs. 4(a) and 4(b), the display shelf 1 according to the present embodiment can be overall in a substantially plate shape when in a folded state. Next, with reference to Figs. 1 to 4(a) and 4(b), the folded state of the display shelf 1 according to the present embodiment will be described.

[0025]

When bringing the display shelf 1 according to the present embodiment into the folded state, first, the frame part 100 is collapsed (crushing the display shelf 1 from the front and the rear directions thereof) such that the front frame part 110 and the rear frame part 120 (the left front frame part 111 and the left rear frame part 121, the middle front frame part 112 and the middle rear frame part 122, and the right front frame part 113 and the right rear frame part 123) approach each other. In conjunction with this, an edge (for example, the front display surface outer edge 31 IE) of the display surface part 300 connected to the frame part 100 moves toward the plate-shaped part 210 side. Further in conjunction with this, the respective display surface parts (the front upper stage display surface part 311, the rear upper stage display surface part 312, the front middle stage display surface part 321, the rear middle stage display surface part 322, the front lower stage display surface part 331, and the rear lower stage display surface part 332) connected to the front frame part 110 move toward the plate-shaped part 210 side. Furthermore, the plate-shaped part 210 is movable in the height direction of the display shelf 1 inside the frame part 100 and is connected to the respective display surface parts via an edge (for example, the front display surface outer edge 311E). Therefore, in conjunction with movement of the display surface part 300, the plate-shaped part 210 moves in the height direction (upward in this figure) of the display shelf 1. That is, the respective edges (for example, the front display surface outer edge 311E) of the respective display surface parts on the side of the frame part 100 move toward the plate-shaped part 210 side, and the respective edges of the respective display surface parts on the center side (for example, the front display surface inner edge 3111) are pushed out in the height direction of the display shelf 1. As a result, the front frame part 110 (for example, the middle front frame part 112 and the middle rear frame part 122), the display surface part 300 (for example, the front upper stage display surface part 311 and the rear upper stage display surface part 312) are substantially parallel to the plate-shaped part 210. At this time, the left secondary support column 221 and the right secondary support column 222 have a substantially plate shape by being collapsed by the frame part 100. Through the above steps, the display shelf 1 according to the present embodiment is folded to an extent that the display shelf 1 has substantially a plate-shape as a whole.

[0026]

Note that when it is desired that the display shelf 1 according to the present embodiment is in a deployed state {a state where the respective display surface parts 300 are deployed to an extent that the frame part 100 forms a peripheral wall of the display shelf 1 and forms a predetermined angle with the plate-shaped part 210, and the left support auxiliary surface 221S (right support auxiliary surface 222S) of the left secondary support column 221 (right secondary support column 222) is in contact with an inner wall surface of the frame part 100}, a process opposite to the above may be followed.

[0027]

In the display shelf 1 according to the present embodiment, the frame part 100, the support part 200, the display surface part 300, the secondary support column 220, and the like, which are main members, are connected directly or indirectly to any one of the members. Therefore, when the display shelf 1 is folded for transitioning from the deployed state to the folded state, for example, in conjunction with folding of the frame part 100, the secondary support column 220 can be (automatically) brought into a collapsed state, and when the display shelf 1 is deployed for transitioning from the folded state to the deployed state, the secondary support column 220 can (automatically) have a tubular shape in conjunction with deploying of the frame part 100.

[0028]

Next, each member of the display shelf 1 according to the present embodiment will be described with reference to Figs. 5(a) to 5(d). Note that this figure is merely an example, and it is not limited as to whether respective members are continuously structured by the same member or different members are joined (bonded or fitted) with each other {for example, when joining an Apart and a B part, another joining member or the like extending over the A part and the B part may be used without providing glue margins as joining surfaces in the Apart and the B part (furthermore in such a case, it is not necessary to directly connect the Apart and the B part)}.

[0029]

Fig. 5(a) is a developed view of the secondary support column 220 (left secondary support column 221). In this manner, the left secondary support column 221 has six folds and seven surfaces divided by the folds. Two surfaces (joining surfaces 221ai and 2210¾) positioned at both side ends thereof serve as joining surfaces (glue margins) with the plate-shaped part 210 (by bending the respective holds, the left secondary support column 221 having a predetermined shape having joining surfaces to the plate-shaped part 210 is formed). Note that the since the right secondary support column 222 is similar to the left secondary support column 221, descriptions thereon are omitted.

[0030]

Fig. 5(b) is a developed view of the plate-shaped part 210. In this manner, the plate-shaped part 210 has a joining surface 210a and a joining surface 210β extending in the height direction at side end parts thereof as joining surfaces (glue margins) with the secondary support column 220 (left secondary support column 221 and right secondary support column 222) and has a joining surface 21 OX, a joining surface 210Y, and a joining surface 210Z extending in the width direction as joining surfaces (glue margins) with the display surface part 300 (the upper stage display surface part 310, the middle stage display surface part 320, and the lower stage display surface part 330). Here, in the plate-shaped part 210 according to the present embodiment, the joining surface 210X, the joining surface 210Y, and the joining surface 210Z serve as beam parts capable of supporting the display surface part 300 (the upper stage display surface part 310, the middle stage display surface part 320, and the lower stage display surface part 330) together with a joining surface 311X, a joining surface 321Y, and ajoining surface 331Z, which will be described later, and the joining surface 210a and the joining surface 210β are support columns supporting the beam parts (the joining surface 21 OX, the joining surface 210Y, and the joining surface 210Z) {Note that, as only by the joining surface 311X, the joining surface 321Y, the joining surface 331Z the display surface part 300 can be supported {for example by connecting the joining surface 31IX, the joining surface 321Y, and the joining surface 331Z to the secondary support column 220 (left secondary support column 221) without providing the plate-shaped part 210 which is a plate-shaped member}, the plate-shaped part 210 is not indispensable as long as the beam parts (support parts of the display surface part 300) of the display surface part 300 are included. {Furthermore, members serving as such beam parts may integrally form the plate-shaped part 210, or an appropriate member (for example, a rod-like member or the like) which does not have a thin plate shape may be used as the beam parts}}.

[0031]

Fig. 5(c) is a developed view of the frame part 100 (front frame part 110). As described above, the front frame part 110 has ajoining surface 110γ which is ajoining surface (glue margin) with the rear frame part 120. Furthermore, in the present embodiment, the front upper stage display surface part 311 and the rear upper stage display surface part 312 are provided by cutting out the front frame part 110 (as members integral with the front frame part 110). Furthermore, the joining surface 31IX (joining surface 321Y) which is ajoining surface (glue margin) with the plate-shaped part 210 is provided at a front end part of the front upper stage display surface part 311 (front middle stage display surface part 321). Note that, in the present embodiment, the front display surface outer edge 31 IE is also a fold between the front upper stage display surface part 311 and the front frame part 110, and the front display surface inner edge 31II is a fold between the front upper stage display surface part 311 and the joining surface 31IX. Note that the rear frame part 120 is similar to the front frame part 110, descriptions thereon are omitted.

[0032]

Fig. 5(d) is a developed view of the lower stage display surface part 330 (front lower stage display surface part 331). The front lower stage display surface part 331 has a joining surface 331Z which is a joining surface (glue margin) with the plate-shaped part 210 and a joining surface 331a which is a joining surface (glue margin) with the front frame part 110. As described above, in the display shelf 1 according to the present embodiment, the upper stage display surface part 310 and the middle stage display surface part 320 are integrated with the frame part 100 while the lower stage display surface part 330 is separate from the frame part 100. Note that the rear lower stage display surface part 332 is similar to the front lower stage display surface part 331, descriptions thereon are omitted.

[0033]

The display shelf 1 according to the present embodiment can be formed by bonding, with an adhesive or the like as required, respective joining surfaces of the respective members described above {For example, the joining surface 221ai and the joining surface 210a, the joining surface 221a2 and the joining surface 210a (the surface opposite to the surface to which the joining surface 221ai is bonded), the joining surface 210X and the joining surface 311X, the joining surface 210Y and the joining surface 321Y, the joining surface 210Z and the joining surface 331Z, the joining surface 331a and a part of an inner wall surface side of the front frame part 110, and the joining surface 110γ and the rear frame part 120}.

[0034]

Note that, in the display shelf 1 according to the present embodiment, the plate-shaped part 210 is formed such that the joining surface 210a and the joining surface 210β, which are joining surfaces with the secondary support column 220, have the same level of height as the height of the secondary support column 220; however, the height is not limited thereto. More specifically, the joining surface 210a and the joining surface 210β function as support columns of the plate-shaped part 210 (support columns against a load applied from the display surface part 300 to the plate-shaped part 210 in the height direction); however, the function of being such a support column is also provided by the secondary support column 220 connected to the plate-shaped part 210. Therefore, in the structure in which the secondary support column 220 is connected (bonded) as the support column of the plate-shaped part 210, the joining surface 21 OX, the joining surface 210Y, and the joining surface 210Z may be separate members (the joining surface 21 OX, the joining surface 210Y, and the joining surface 210Z are not connected to the joining surface 210a or the joining surface 210β) (The joining surface 21 OX, the joining surface 210Y, and the joining surface 210Z serve as beam parts for supporting the display surface part 300, and the secondary support column 220 serves as a support column for supporting the joining surface 21 OX, the joining surface 210Y, and the joining surface 210Z).

[0035]

Here, in the display shelf 1 according to the present embodiment, in addition to the secondary support column 220 functioning as a support part for supporting a load on the display surface part 300 or the plate-shaped part 210, various effects can be exerted such as: improvement in fixation of the respective members by being in contact with an inner wall of the frame part 100 {Tensile force (force of the secondary support column 220 pulling the frame part 100 outward) by the secondary support column 220 acts, and fixation of the respective members in the entire display shelf 1 is improved. (Compared with the case of only the plate-shaped part 210, not only a position of the secondary support column 220 itself is facilitated to be fixed due to an increase in a contact area with the frame part 100 but also looseness among members in the deployed state is decreased due to the tensile force applied to the frame part 100 by the secondary support column 220, whereby fixation of the respective members is improved.) As a result, installation stability, shock resistance, or other features of the display shelf 1 may be improved.}; and preventing external stress applied to the frame part 100 from being directly transmitted to an important member (for example, the display surface part 300 and surrounding members) (The deformable secondary support column 220 serves as a relay point for transmission of external force and the secondary support column 220 itself is deformed to relieve the force in a twisting direction of the entire display shelf 1, such as functioning as a cushion material, thereby the external stress is dispersed).

[0036]

In particular, in the display shelf 1 according to the present embodiment, by including the secondary support column 220 (the left secondary support column 221 and the right secondary support column 222), the secondary support column 220 is capable of transitioning to the collapsed state (for example, a plate-shaped state) while aforementioned various effects are obtained. Therefore, the volume can be kept at the same level as that of conventional foldable display shelves.

[0037]

Here, the secondary support column 220 may be provided only on one side part of the plate-shaped part 210 (for example, only the left secondary support column 221 is provided and the right secondary support column 222 is not provided). In this case, an end part of the support part 200 on a side where the secondary support column 220 is not provided is in a state in which the plate-shaped part 210 can contact the frame part 100.

[0038]

Furthermore, in the display shelf 1 according to the present embodiment, the display surface part 300 includes three stages (the upper stage display surface part 310, the middle stage display surface part 320, and the lower stage display surface part 330); however, without limited thereto, the display surface part 300 may be formed as a single stage or any number of stages of two or more stages.

[0039]

Note that, in the display shelf 1 according to the present embodiment, the display surface part 300 may be formed by the front upper stage display surface part 311, the front middle stage display surface part 321, and the front lower stage display surface part 331 {The front upper stage display surface part 311 (the front middle stage display surface part 321 or the front lower stage display surface part 331) is not provided on a surface opposite to a surface connected to the front upper stage display surface part 311 (the front middle display surface part 321 or the front lower stage display surface part 331) of the plate-shaped part 210}. Also in such a display shelf {the display surface part protrudes only to one side of a point (for example, the plate-shaped part 210) which is a starting point of bending}, the concept of the secondary support column 220 of the display shelf 1 according to the present embodiment can be applied.

[0040]

In addition, in the present embodiment, the height of the secondary support column 220 is set to be substantially the same as the height of the upper stage display surface part 310. With such a structure, since the secondary support column 220 is in wide contact with the plate-shaped part 210 and the frame part 100 in the height direction, force applied to the display shelf 1 is easily dispersed in the secondary support column 220 (strength of the display shelf 1 can be further enhanced). Meanwhile, without limited thereto, the height of the secondary support column 220 may be higher than that of the upper stage display surface part 310. In this case, for example, a part higher than the upper stage display surface part 310 may be used for a pop or other use. Furthermore, the height of the secondary support column 220 may be lower than the height of the upper stage display surface part 310 (the height of the plate-shaped part 210). In this case, folding and deploying of the upper stage display surface part 310 are unlikely to be disturbed by the secondary support column 220, and thus the opening 350 may not be included.

[0041]

In addition, it is preferable that the secondary support column 220 is provided so as to be able to contact the installation surface of the display shelf 1 (for example, a plane is shared with the frame part 100 or the plate-shaped part 210 at a lower end part thereof). With such a structure, a load applied to the display shelf 1 (in particular, a load of articles, which is a load from the height direction of the display shelf 1) can be dispersed to the secondary support column 220, thus further enhancing the strength of the display shelf 1. Also, the secondary support column 220 may be hindered from being in contact with or unlikely to be in contact with the installation surface of the display shelf 1 (as a structure in which the secondary support column 220 is not in contact with the frame part 100, for example, the secondary support column 220 is provided only in the vicinity of the left and right frame parts of the middle stage support opening 211 and the lower stage support opening 212 of the plate-shaped part 210). Even with such a structure, the secondary support column 220 can still function as a cushion material.

[0042]

In principle, the display shelf 1 according to the present embodiment is made of a flexible material (for example, paper, leather, some plastics, etc.); however, a material having no flexibility (for example, plastic, glass, metal, wood, etc.) may be partially used (for example, a member a shape of which is not required to be deformed in transition between the folded state and the deployed state such as a part of the plate-shaped part 210 or the display surface part 300).

[0043]

Here, in the aforementioned display shelf 1, the secondary support column 220 is formed to have a pentagonal tubular shape (a tubular shape a horizontal cross section of which is a pentagonal shape), the frame part 100 is formed to have a hexagonal tubular shape (a tube whose horizontal cross section is a pentagonal shape); however, without particularly limited thereto, various shapes (for example, any polygonal tubular shape) may be employed. Hereinafter, shapes of the secondary support column 220 and the frame part 100, which are different from the display shelf 1 illustrated in Fig. 1 and other drawings, will be specifically illustrated with reference to Figs. 6 to 10.

Note that Figs. 6 to 10 are views extracting a part of a top view of the display shelf (a part of the left side part of the display shelf 1) illustrating positional relations of the frame part 100, the support part 200 {the plate-shaped part 210 and the secondary support column 220 (left secondary support column 221)}, the front upper stage display surface part 311, and the rear upper stage display surface part 312. In addition, in Figs. 6 to 10, a hatched part corresponds to the opening 315.

[0044]

First, as illustrated in Fig. 6, the shape of the secondary support column 220 may be a triangular tubular shape. Furthermore, in this case, the left display opening 315 may also be a triangular opening corresponding to the shape of the secondary support column 220. Note that the frame part 100, the plate-shaped part 210, the front upper stage display surface part 311, and the rear upper stage display surface part 312 are similar to those in Figs. 1 to 4(a) and 4(b), and thus descriptions thereon are omitted.

[0045]

In addition, as illustrated in Fig. 7, the shape of the secondary support column 220 may be a square tubular shape. Furthermore, the shape of the left display opening 315 may be any appropriate shape as long as the secondary support column 220 can penetrate therethrough (it is not necessary to have a shape similar to the shape of the secondary support column 220). Note that the frame part 100, the plate-shaped part 210, the front upper stage display surface part 311, and the rear upper stage display surface part 312 are similar to those in Figs. 1 to 4(a) and 4(b), and thus descriptions thereon are omitted.

[0046]

Note that the frame part 100 may have a structure other than the aforementioned tubular structure. More specifically, since the frame part 100 comprehensively refers to members forming side walls (for example, side walls of the display surface part 300) of the display shelf 1, a structure thereof can be changed as appropriate as long as the frame part 100 can stand together with other members (for example, support part 200 and other parts) forming the display shelf 1. For example, in the display shelf 1 according to Fig. 1, the frame part 100 may have a structure in which the front frame part 110 and the rear frame part 120 are not connected (A structure in which the front frame part 110 and the rear frame part 120 are not in direct contact with each other and are connected via another member), or the front frame part 110 may be formed by two members, and the two members may not be connected with each other. Note that the structure in which the frame part 100 is formed by two or more members and they are not directly connected to each other will be exemplified in a third embodiment which will be described later.

[0047]

Furthermore, as illustrated in Fig. 8, the plate-shaped part 210 and the secondary support column 220 may be formed by a single continuous member (In this case, for example, a side end part of the plate-shaped part 210 may be folded or rounded by an appropriate method to form a tubular shape, thereby forming the secondary support column 220.). Note that the frame part 100, the front upper stage display surface part 311, and the rear upper stage display surface part 312 are similar to those in Figs. 1 to 4(a) and 4(b), and thus descriptions thereon are omitted.

[0048]

Next, as illustrated in Figs. 9 and 10, the shape of the frame part 100 may be a square tubular shape. Also in this case, the vicinity of the center in the depth direction (vertical direction in Figs. 9 and 10) of the frame part 100 can be folded (the frame part 100 can be in a plate shape by being folded at this portion). Also in this case, the left display opening 315 may have any appropriate shape. Note that the plate-shaped part 210, the secondary support column 220, the front upper stage display surface part 311, and the rear upper stage display surface part 312 are similar to those in Figs. 1 to 4(a) and 4(b), and thus descriptions thereon are omitted.

[0049]

Here, as described above, effects of the secondary support column 220 includes that external force applied to the frame part 100 is prevented from being directly transmitted to the plate-shaped part 210 or surrounding members (The secondary support column 220 serves as a relay point of the external force and the secondary support column 220 itself is deformed to function as a cushion material). In a case where it is desired to further enhance such an effect, when assuming a plane on which the plate-shaped part 210 exists, it is preferable that the inner wall surface part of the secondary support column 220 intersecting the plane and end parts of the plate-shaped part 210 are separated from each other in a state in which the display shelf is in a deployed state and no external force is applied to the display shelf (for example, a structure as illustrated in Fig. 8) {There is a play (not in direct contact) between the end parts of the plate-shaped part 210 and the inner wall surface of the secondary support column 220 on the side of the frame part 100}. By providing a space between the inner wall surface part of the secondary support column 220 and the end parts of the plate-shaped part 210 in this manner, a deformation area of the secondary support column 220 in the deployed state increases, and cushioning characteristics of the secondary support column 220 can be improved.

[0050]

Furthermore, in the display shelf 1 illustrated in Fig. 1 and Figs. 6 to 8, a structure is adopted in which the secondary support column 220 is in contact with the inner wall surface of the frame part 100 in a planar manner {For example, there are two or more contact surfaces between the secondary support column 220 and the frame part 100 (the secondary support column 220 and the frame part 100 are in contact with each other across a plurality of planes). In the display shelf illustrated in Figs. 9 and 10, a contacting surface between the secondary support column 220 and the frame part 100 is a single surface (The secondary support column 220 and the frame part 100 are in contact with each other in a planar manner)}. In this manner, the secondary support column 220 and the frame part 100 are in contact with each other in a planar manner, and particularly in contact with each other across a plurality of planes. This facilitates the secondary support column 220 to be easily held by the plurality of surfaces, and thus fixation of the support part 200 (plate-shaped part 210) and fixation of each of the members of the display shelf 1 are improved. It is therefore possible to further improve installation stability, shock resistance, or other characteristics of the display shelf. On the other hand, the secondary support column 220 and the inner wall surface of the frame part 100 are not necessarily required to be in contact with each other.

[0051]

Here, in the aforementioned display shelf 1, although the structure in which the secondary support column 220 is brought into a tubular shape in the deployed state has been described. However, a feature of the secondary support column 220 is that the secondary support column 220 is in the collapsed state in the folded state and change the shape thereof to improve the strength of the display shelf 1 in the deployed state. From this perspective, the shape of the secondary support column 220 is not limited to a tubular shape. An example of such a structure is illustrated in Figs. 11(a) and 11(b) to 14. Note that Figs. 11(a) and 11(b) to 14 are views extracting a part of the top view of the display shelf (a part of the left side part of the display shelf) in which the display surface part 300 is not illustrated while only the frame part 100, the plate-shaped part 210, and the secondary support column 220 are illustrated.

[0052]

As illustrated in Figs. 11(a) to 12(b), the secondary support column 220 (left secondary support column 221) may have a shape obtained by appropriately folding a plate-shaped member {expanded state of being non-annular (open shape) in a cross section in the height direction of the secondary support column 220 (left secondary support column 221)}. Also in this case, a load on the display shelf 1 can be dispersed by the secondary support column 220 (left secondary support column 221). Also with such a structure, it is possible for the secondary support column 220 (left secondary support column 221) to be in contact with the inner wall surface of the frame part 100 in a planar manner. More specifically, with the left support auxiliary surface 221S being a contacting surface with the frame part 100,effect can be exerted such as improvement in fixation of the support part 200 or improvement in strength by cushioning characteristics due to deformation of the secondary support column 220 itself {Note that, from the perspective of improving such cushioning characteristics, it is preferable that the secondary support column 220 has a tubular shape (annular shape in a cross section in the height direction thereof)}.

[0053]

Note that the as illustrated in Figs. 11(a) and 11(b), the secondary support column 220 (left secondary support column 221) and the plate-shaped part 210 may be separate bodies. Alternatively, as illustrated in Fig. 12(a) and 12(b), the secondary support column 220 (left secondary support column 221) may extend from the plate-shaped part 210. Moreover, the plate-shaped part 210 may be formed by bonding a plurality of plate-shaped members together.

[0054]

In addition, in the display shelf illustrated in Figs. 11(a) to 12(b), in order for the secondary support column 220 (left secondary support column 221) to be deployed in conjunction with deploying of the frame part 100, it is only required that stress acts in a direction in which the secondary support column 220 (left secondary support column 221) expands outward in the deployed state. {For example, an elastic member may be provided to the secondary support column 220 (left secondary support column 221) as appropriate.} [0055]

Here, in Figs. 11(a) to 12(b), the structure in which the secondary support column 220 (left secondary support column 221) has a surface that can be brought into contact with the frame part 100 in the deployed state of the display shelf 1 has been described {More specifically, the structure in which the secondary support column 220 (left secondary support column 221) has an expanded shape expanding toward the center of the display shelf}; however, a structure is not limited thereto. For example, as illustrated in Figs. 13 and 14, when the thickness of members is not considered, the secondary support column 220 (left secondary support column 221) may be in contact with the frame part 100 at a point and not in a planar manner in the deployed state {More specifically, the secondary support column 220 (left secondary support column 221) has an expanded shape expanding toward the outside of the display shelf}. (Note that the number of contacting points between the secondary support column 220 (left secondary support column 221) and the frame part 100 is two in Fig. 13 and three in Fig. 14; however, these can be changed as appropriate.

[0056]

Note that as illustrated in the figures, the secondary support column 220 (left secondary support column 221) is in contact with the frame part 100 at a plurality of points (each of the front side and the rear side of the frame part 100 when divided by a line at the center of folding), and thus the secondary support column 220 (left secondary support column 221) also naturally expands in accordance with deployment of the frame part 100 {Stress from the front frame part of the frame part 100 and stress from the rear frame part of the frame part 100 are applied, and the secondary support column 220 (left secondary support column 221) is thereby expanded with a joined surface with the plate-shaped part 210 serving as an axis}.

[0057]

In the above, as the display shelf 1 according to the first embodiment, a structure in which the secondary support column 220 functions as a support column or a cushion material by using the secondary support column 220 as a columnar auxiliary member (columnar member), and strength of the display shelf 1 can be improved has been described above. Here, particularly in the case where the secondary support column 220 has a tubular shape, the secondary support column 220 may be used for another purpose. Such another use of such a secondary support column 220 will be described with reference to Figs. 15 and 16.

[0058]

First, as illustrated in Fig. 15, in the display shelf 1 according to the present embodiment, the secondary support column 220 of a tubular shape may be a member for receiving a rod-shaped (or tubular) auxiliary support column member 280. With such a structure, the auxiliary support column member 280 serves as a core material, and strength of the display shelf 1 can be further improved at the time of deploying without increasing the volume of the folded display shelf 1 by removing the auxiliary support column member at the time of folding.

[0059]

Next, Fig. 16 is a diagram schematically illustrating the display shelf 1 provided with tubular secondary support columns 220 (left secondary support column 221 and right secondary support column 222) on side parts thereof (left side part and right side part) (such a schematic display shelf is referred to as a display shelf X and a display shelf X'). Here, in the display shelf X (display shelf X') according to the present drawing, the secondary support column 220 (left secondary support column 221 and right secondary support column 222) opens in the height direction (upward and downward) of the display shelf and thus a different member can be inserted in the opening. Therefore, by using coupling members (left coupling member 291 and right coupling member 292) having a margin in the height direction in the state of being inserted in the opening, the two display shelves (display shelf X and display shelf X') can be connected to each other in the height direction via the secondary support column 220 (left secondary support column 221 and right secondary support column 222). At this time, the left secondary support column 221 of the display shelf X and the right secondary support column 222 of the display shelf X' may be connected by a coupling member. Note that Fig. 16 is merely an example, and the shape of the coupling member is not limited at all as long as a plurality of display shelves can be connected.

[0060]

Note that such a coupling member (left coupling member 291 and right coupling member 292) can be appropriately applied to a display shelf having a structure (for example, a tubular structure) a cross section in the height direction of which is annular.

[0061] <Modification>

As described above, in the display shelf 1 according to the present embodiment, the case where the frame part 100 and the secondary support column 220 are in a polygonal tubular shape has been describe; however, the frame part 100 and the secondary support column 220 may be tubular (tubular shape a horizontal cross section of which is a circle or an ellipse). Next, a display shelf 1 according to a modification of the present embodiment in the case where a frame part 100 has a tubular shape will be described in detail.

[0062]

As illustrated in Figs. 17 and 18, the display shelf 1 according to the present embodiment has, like the display shelf according to Fig. 1, a frame part 100 {front frame part 110 and rear frame part 120}, a support part 200 {plate-shaped part 210, secondary support column 220 (left secondary support column 221)}, a display surface part 300 {upper stage display surface part 310 (front upper stage display surface part 311 and rear upper stage display surface part 312), lower stage display surface part 330 (front lower stage display surface part 331 and rear lower stage display surface part 332}. Furthermore, while the display shelf 1 according to the present embodiment has two display surface parts (upper stage display surface part 310 and lower stage display surface part 330), in order to reinforce strength of the plate-shaped part 210, a reinforcing beam 250 extending in the horizontal direction of an opening of the plate-shaped part 210 is provided.

[0063]

As illustrated in Fig. 18, connections or contacting relations among the frame part 100, the secondary support column 220 (left secondary support column 221), and the display surface part 300 are similarly to those of the display shelf 1 according to Fig. 1 and other display shelves. That is, the front upper stage display surface part 311 (rear upper stage display surface part 312) is connected to the front frame part 110 via a front display surface outer edge 311E (rear display surface outer edge 312E) and is connected to the plate-shaped part 210 via a front display surface inner edge 3111 (rear display surface inner edge 3121). Also, the left secondary support column 221 (right secondary support column 222) is in contact with the frame part 100 via a left support auxiliary surface 22 IS (right support auxiliary surface 222S) which is a part of a surface forming the left secondary support column 221 (right secondary support column 222). Furthermore, between the upper stage display surface part 310 (the front upper stage display surface part 311 or the rear upper stage display surface part 312) and the frame part 100 (in the deployed state, between the frame part 100 and the upper stage display surface part 310), the secondary support column 220 (left secondary support column 221 and right secondary support column 222) includes openings (left display opening 315 and right display opening 316) which can penetrate in the height direction of the display shelf 1 {when the display shelf 1 is viewed from the height direction, the secondary support columns 220 (the left secondary support column 221 and the right secondary support column 222) can be seen. Note that, in the display shelf 1 according to the present embodiment, the plate-shaped part 210 is formed by bonding a front plate-shaped part 215 and a rear plate-shaped part 216, which are two plate-shaped members. Furthermore, the front upper stage display surface part 311 is continuously formed on the front plate-shaped part 215 and the rear upper stage display surface part 312 is continuously formed on the rear plate-shaped part 216 (via the front display surface inner edge 3111 and the rear display surface inner edge 3121 each serving as a fold).

[0064]

Furthermore, the display shelf 1 according to the present embodiment has the frame part 100 of a tubular shape and, unlike the display shelf 1 according to Fig. 1, does not include a middle front frame part 112 (plane-shaped frame part that forms one side of a hexagonal tube). Therefore, as illustrated in Fig. 18, the front display surface outer edge 311E and the rear display surface outer edge 312E which are connecting parts with the frame part 100 (front frame part 110 and rear frame part 120) and the upper stage display surface part 310 (front upper stage display surface part 311 and rear upper stage display surface part 312) and folding edges of the upper stage display surface part 310 (front upper stage display surface part 311 and rear upper stage display surface part 312) are provided in a foldable manner at a part near the center of the front frame part 110 and the rear frame part 120 (in the case where the frame part 100 has a tubular shape, the front display surface outer edge 311E and the rear display surface outer edge 312E are not necessarily linear; however, since this part is the folded, bending property and the length to allow folding are required considering flexibility of each of the members).

[0065] «Second Embodiment»

In the first embodiment, as a display shelf provided with a columnar member at least a part of which is in the collapsed state in a cross section in the height direction of the display shelf in the folded state and, in the deployed state, has an annular shape or in the expanded state in a cross section in the height direction of the display shelf, the display shelf 1 provided with the secondary support column 220 which is the columnar member at the side end parts of the plate-shaped part 210 has been described. Next, as a similar concept, a structure in which the secondary support column 220 and the plate-shaped part 210 are formed as separate bodies and the secondary support column 220 as the columnar member is provided (bonded) to the frame part 100 will be described as a display shelf 2 according to a second embodiment.

[0066]

Fig. 19 is a developed view of the display shelf 2 according to the second embodiment. As illustrated in a right diagram of Fig. 19, the display shelf 2 according to the second embodiment does not have the plate-shaped part 210 which is a member for supporting the display surface part 300 in the display shelf 1 according to the first embodiment, but has ajoining surface 311X, a joining surface 321Y, and ajoining surface 331Z extending in the width direction beyond each of the display surface parts as joining surfaces (glue margins) with the front side part and the rear side part of the display surface part 300 (upper stage display surface part 310, middle stage display surface part 320, and lower stage display surface part 330). The joining surface 31IX, the joining surface 321Y, and the joining surface 331Z have a shape longer in the width direction than the display surface part 300 (a shape having a margin), and as illustrated in a left diagram of Fig. 19, the margin protruding from the display surface part 300 is inserted into a hole (hole 221X, hole 221Y, hole 221Z, hole 222X, hole 222Y, and hole 222Z) included in another columnar member {secondary support column 220 (left secondary support column 221 and right secondary support column 222) and thereby functions as a beam capable of supporting the display surface part 300. Although not illustrated, the secondary support column 220 is a tubular structure joined to an inner wall side of the frame part 100. When the display shelf 2 is folded, in conjunction with collapsing of the frame part 100, the secondary support column 220 is also collapsed. Furthermore, when the display shelf 2 is folded, the joining surface 31IX, the joining surface 321Y, and the joining surface 331Z come off the hole (hole 22IX, hole 221Y, hole 221Z, hole 222X, hole 222Y, and hole 222Z), and is separated from the secondary support column 220. Note that, at this time, it is not required to completely separate the joining surface 311X, the joining surface 321Y, and the joining surface 331Z from the secondary support column 220, but it only required that the joining surface 311X, the joining surface 321Y, and the joining surface 331Z and the secondary support column 220 can move independently (the joining surface 31IX, the joining surface 321Y, and the joining surface 331Z and the secondary support column 220 can be separated) {For example, in a case where the hole (hole 221X, hole 221Y, hole 221Z, hole 222X, hole 222Y, and hole 222Z) has a slit shape, the joining surface 31IX, the joining surface 321Y, and the joining surface 331Z can move independently of the secondary support column 220 (the display shelf 2 can be folded) even when inserted in the hole}. Note that the shape of the margin protruding from the display surface part 300 {protruding part that can be inserted into the hole (hole 221X, hole 221Y, hole 221Z, hole 222X, hole 222Y, and hole 222Z)} may be partially in a hook shape in order to further improve fixation in the deployed state {by providing such a hook-shaped part, the hook-shaped part is caught by an edge of the hole, thereby improving fixation of the margin (protruding part)}.

[0067]

As described above, in the display shelf 2 according to the present embodiment, the beam parts that support the display surface part 300 in the deployed state are independent from each other (The frame part supporting the display surface part 300 is not included in one member like the plate-shaped part 210 according to the first embodiment, but the joining surface 311X, the joining surface 321Y, and the joining surface 331Z to form the beam parts are provided in such a manner as to extend independently from each of the display surface parts.).

[0068]

Here, in the display shelf 2 according to the present drawing, upon transition from the deployed state to the folded state, the secondary support column 220 (left secondary support column 221 and right secondary support column 222) is bonded to the frame part 100 and thus does not move in the height direction while the joining surface 311X, the joining surface 321Y, and the joining surface 331Z each bonded to the upper stage display surface part 310, the middle stage display surface part 320, and the lower stage display surface part 330, respectively, move in the height direction of the display shelf 2 in conjunction with movement of each of the display surface parts.

Here, it is suitable that the holes (hole 221Y, hole 221Z, hole 222Y, and hole 222Z) into which the joining surface 321Y and the joining surface 331Z are inserted have a slit shape (the hole extends in a direction of movement of each of the joining surfaces). In the deployed state of the display shelf 2, the joining surface 321Y and the joining surface 331Z are inserted in the secondary support column 220. In the folded state of the display shelf 2, however, the joining surface 311X, the joining surface 321Y, and the joining surface 331Z can move in the height direction of the display shelf 2. At this time, by allowing each of the holes to have a slit shape, the joining surface 321Y and the joining surface 331Z extending to the side of the secondary support column 220 (extending parts of the joining surface 321Y and the joining surface 331Z to be inserted into the secondary support column) becomes unlikely to interfere with the secondary support column 220 when moving. In this manner, shapes of the joining surface 31IX, the joining surface 321Y, and the joining surface 331Z and the connection method with the secondary support column 220 can be designed as appropriate. Note that other structures are similar to those of the display shelf 1 according to the first embodiment and thus descriptions thereon are omitted.

[0069]

Note that in this embodiment, the joining surface 31IX, the joining surface 321Y, and the joining surface 331Z are inserted into the holes included in the secondary support column 220; however, without limited thereto, a connection method among the joining surface 311X, the joining surface 321Y, and the joining surface 331Z and the secondary support column 220 in the deployed state may be any method. For example, a protruding part may be provided to the secondary support column 220, and the joining surface 311X, the joining surface 321Y, and the joining surface 331Z may be placed on or fitted to the protruding part (in this case, the joining surface 31IX, the joining surface 321Y, and the joining surface 331Z are not required to extend in the width direction beyond the display surface part 300).

[0070]

As described above, the display shelf 2 according to the second embodiment has a structure in which the secondary support column 220, which is a columnar member, is joined to the frame part 100 and in conjunction with collapsing of the frame part 100, the secondary support column 220 is also collapsed.

[0071]

Here, a structure of the secondary support column 220 is only required to have a shape which can be collapsed. Although the pentagonal tubular shape as illustrated in the display shelf 1 according to the first embodiment has been exemplified, a structure is not limited thereto. For example, the secondary support column 220 illustrated in Fig. 20 has a pentagonal tubular shape like the secondary support column 220 in the display shelf 1 according to the first embodiment, but has a different collapsing method. More specifically, in the display shelf 2 according to the present drawing, the secondary support column 220 has a closed tubular shape in the deployed state; however, the secondary support column 220 (left secondary support column 221 and right secondary support column 222) can be opened at one side thereof. Therefore, by opening one side at the time of folding, the tubular part is not collapsed while maintaining the tubular shape, but is collapsed as two plate-shaped parts and is folded together with the frame part 100. Note that a method of joining the opened annular part at the time of assembling can be freely selected as appropriate such as providing recessed and protruding parts at both sides to allow the recessed and protruding parts to be engaged, or using a hook and loop fastener.

[0072] «Third Embodiment»

In the display shelf 2 according to the second embodiment, the structure in which the secondary support column 220, which is a columnar member, is provided to the frame part 100 and the secondary support column 220 and the plate-shaped part 210 are separate bodies has been described. In addition, in the first embodiment and the second embodiment, the structure in which the secondary support column 220 is connected to a member supporting the display surface part 300 (the plate-shaped part 210, or the joining surface 31IX, the joining surface 321Y, and the joining surface 331Z that are also a beam part) has been described. Here, a structure of a display shelf having a member, which is a columnar member brought into the collapsed state in the folded state and annular in a cross section in the deployed state while not directly not supporting the display surface part 300 unlike the secondary support column 220 according to the first embodiment and the second embodiment (the columnar member is not directly connected to the display surface part 300), will be described with reference to Figs. 21 to 24 as a display shelf 3 according to a third embodiment (note that the display surface part 300 is not illustrated in Figs. 21 to 24, and further the support part 200 is not illustrated in a part of Figs. 21 to 24).

[0073]

With reference to Fig. 21, the structure of the display shelf 3 according to the third embodiment will be described. Note that the display shelf 3 according to the third embodiment is similar to the display shelf 1 according to the first embodiment except for that the secondary support column 220 is not provided but an auxiliary frame part 150, which will be described later, is provided. Thus, descriptions on specific structures of respective parts of a frame part 100, a support part 200 and a display surface part 300, basic mechanisms of folding and deploying, and the like are omitted.

[0074]

As illustrated in Fig. 21, the display shelf 3 according to the present embodiment is provided with auxiliary frame parts 150 each forming a V-letter-shaped tubular shape (tubular shape a cross section of which in the height direction is, as a whole, a “V” letter-shaped annulus) to the frame part in such a manner as to circumference the frame part 100 in the deployed state. By providing such an auxiliary frame part 150, the auxiliary frame part 150 functions as a cushion material for the display shelf 3 like the aforementioned secondary support column 220 and other members and supports the display shelf 3, thereby enabling improvement in strength of the display shelf 3.

[0075]

Here, in such an auxiliary frame part 150, an auxiliary frame part inner edge 151 positioned on an inner side (in this figure, the side in contact with the frame part 100) with respect to the display shelf 3 and an auxiliary frame part outer edge 152 positioned on an outer side with respect to the display shelf 3 have different lengths. More specifically, by allowing the length of the auxiliary frame part inner edge 151 to be shorter than the length of the auxiliary frame part outer edge 152, when the display shelf 3 is folded, the auxiliary frame part 150 can be also brought into the collapsed state (folded) in conjunction with collapsing of the frame part 100.

[0076]

Here, the shape of the auxiliary frame part 150 is not limited to a V-letter-shaped tubular shape, but is only required to be a column member structured to be deployed in conjunction with the frame part 100 when the display shelf 3 is deployed and, when the display shelf 3 is folded, to be collapsed in conjunction with the frame part 100 (for example, a tubular member) (for example, the shape can be freely set as appropriate in accordance with the shape and the like of the frame part 100, such as a substantial triangular tubular shape in the deployed state like the auxiliary frame part 150 according to Fig. 22).

[0077]

In addition, as illustrated in Fig. 22, as arrangement of the auxiliary frame part 150, the auxiliary frame part 150 may be provided to be inscribed in the frame part 100 (the auxiliary frame part outer edge 152 and the frame part 100 are in contact with each other). Also in this case, the effect of improving strength of the display shelf 3 can be exerted. Note that in the display shelf 3 illustrated in Fig. 22, the auxiliary frame part 150 is in contact with the plate-shaped part 210, and as a result, the auxiliary frame part 150 can also function as a member for supporting the plate-shaped part 210.

[0078]

Furthermore, as illustrated in Figs. 23 and 24, in the display shelf 3 provided with the auxiliary frame part 150, the aforementioned secondary support column 220 may be further provided {Fig. 23 (Fig. 24) has a structure in which a secondary support column 220 is further provided to be connected to the plate-shaped part 210 in the display shelf illustrated in Fig. 21 (Fig. 22)}.

[0079]

Note that the auxiliary frame part 150 and the frame part 100 are only required to be joined by an appropriate means, and the joining means is not limited at all.

[0080]

Here, in a case where the aforementioned auxiliary frame part 150 (a structure that becomes a tubular shape in the deployed state) is provided so as to be inscribed or circumscribed to the frame part 100, the auxiliary frame part 150 can exert the function as the frame part 100 (particularly, a side wall part of the display shelf). Such a structure will be described with reference to Figs. 25 and 26.

[0081]

The display shelf according to Fig. 25 (Fig. 26) has a structure in which a part of the frame part 100 illustrated in Fig. 21 (Fig. 22) is replaced by the auxiliary frame part 150. More specifically, the frame part 100 is divided into a front frame part 110 and a rear frame part 120, and on a left side of the front frame part 110, a joining surface llOAas a joining surface (glue margin) with an auxiliary frame part inner edge 151 of the auxiliary frame part 150 is included, and, on a right side of the front frame part 110, a joining surface 110B as a joining surface (glue margin) with the auxiliary frame part inner edge 151 of the auxiliary frame part 150 is included. On a left side of the rear frame part 120, a joining surface 120A as a joining surface (glue margin) with the auxiliary frame part inner edge 151 of the auxiliary frame part 150 is included, and, on a right side of the rear frame part 120, a joining surface 120B as a joining surface (glue margin) with the auxiliary frame part inner edge 151 of the auxiliary frame part 150 is included. Furthermore, each of the joining surfaces and the auxiliary frame part 150 are joined so as to be in contact with an outer side (inner side) of the front frame part 110 and the rear frame part 120. Other members (structures of the auxiliary frame part 150, the plate-shaped part 210, etc.) are similar to those in Fig. 21 (Fig. 22). Note that the in this case, the auxiliary frame part outer edge 152 of the auxiliary frame part 150, the front frame part 110, and the rear frame part 120 can together form the frame part of the display shelf.

[0082]

Here, the display shelves illustrated in Figs. 25 and 26 are display shelves illustrated in Figs. 21 and 22 in which a part of the wall surfaces where members overlaps (two sheets are bound together) is changed to a wall surface where members do not overlap (two sheets are not bound together) and thus similar functions as those of the display shelf illustrated in Figs. 21 and 22 can be exerted (note that, in the display shelf illustrated in Fig. 21, the same also applies to a structure in which a part or all of the auxiliary frame part inner edge 151 of the auxiliary frame part 150 overlapping with the frame part 100 is removed). Likewise, other methods may be used as a method of modifying the structure of wall surfaces on which members overlap. For example, the display shelf illustrated in Fig. 27 is the display shelf according to Fig. 22 in which a part of the structure around the frame part 100 (side wall surface) is modified like in Fig. 26. More specifically, as illustrated in Fig. 22, instead of the structure in which the columnar part is formed by providing the annular auxiliary frame part 150 so as to be inscribed in the frame part 100, a structure is employed in which a non-annular auxiliary frame wall part 160 in which a joining surface 160 A and a joining surface 160B as joining surfaces (glue margin) extend is included, and the joining surface 160A and the joining surface 160B are joined to the inner wall surface of the frame part 100 such that the auxiliary frame wall part 160 is installed inside the frame part 100. Also in such a structure, a space surrounded by the auxiliary frame wall part 160 and the frame part 100 can perform a similar function to that of the columnar part (auxiliary frame part 150) in the display shelf illustrated in Fig. 22 (note that in the display shelf illustrated in Fig. 27, the auxiliary frame wall part 160 and the plate-shaped part 210 are not necessarily in contact with each other). Furthermore, the display shelves illustrated in Figs. 25 to 27 may further include a secondary support column 220 (structure incorporating the structure as illustrated in Figs. 23 and 24). As described above, the one provided with the columnar part (the auxiliary frame wall part 160 and the auxiliary frame part 150) is not specifically limited as long as the deployed display shelf can be installed (structure that does not collapse as a shelf), and the display shelf can be folded. For example, the columnar part may have a structure to be in the expanded state in the deployed state (for example, a structure like that of the secondary support column 220 illustrated in Fig. 12(a) and 12(b)), and may be combined with the frame part 100 having a desired shape. The display shelf 3 according to the present embodiment may be formed by freely combining the aforementioned concepts.
