Description

  The present invention relates to a column member that is installed in a store such as a department store, a supermarket, a convenience store, etc., and is suitable for constituting a product display fixture for displaying and selling a product, and a product display fixture. ) In relation to a strut member (strut structure) that effectively reduces the amount of material used.

  The column members constituting the conventional product display fixtures are usually formed into a rectangular cross section by cold roll forming (roll forming) in which a continuous bending process is applied to a metal plate (flat plate) such as a single steel plate. It is generally manufactured by welding the butt joints at both ends, and then finishing the butt welds (cutting extra work, flat finishing) and then painting. is there. For example, the support described in Patent Document 1 proposed by the present applicant is also manufactured by cold roll forming, and this cold roll forming method is capable of mass-producing square tubular support members at low cost. It is widely known as a suitable processing method.

  In addition, the strut member is a load of a product placed on a shelf board supported by a bracket engaged with a locking hole formed in the front surface portion and the rear surface portion (either the front surface portion or the rear surface portion of the strut member). In order to have a structure capable of withstanding a load of, for example, about 400 to 800 kgf, the load applied to one shelf attached to one side of the plate is usually set to 2 as the thickness of the metal plate constituting the column member. It was necessary to be about 3 mm.

  Furthermore, when manufacturing a support | pillar member from one metal plate by cold roll shaping | molding, at the time of shaping | molding to a rectangular cross section, the butt | matching edge parts of the shape | molded metal plate are predetermined according to generation | occurrence | production of the distortion by a springback. In some cases, molding cannot be performed so that the butt position is reached. In such a case, there is a problem that work is inferior because it takes time to finish the butt weld portion formed by welding performed thereafter. In addition, since the spring back tends to be prominently generated by increasing the bending rigidity of the metal plate as the thickness of the metal plate increases, the plate of the metal plate is used from the viewpoint of manufacturing the column member by cold roll forming. It is considered desirable to make the thickness as thin as possible.

  Furthermore, in recent years, with the increase in cost of materials (for example, steel materials) of members constituting commodity display fixtures (products), it has been required to reduce the amount of materials used. It has become necessary to reduce. In addition, it is desirable to reduce the weight of the commodity display fixture from the viewpoint of movement due to layout changes, assembly, and disassembly work.

Next, embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows the appearance of a typical commodity display fixture according to the present invention, FIG. 2 shows a first embodiment of a column member according to the present invention, and FIG. 2 is an exploded view of the column member shown in FIG.

  A product display fixture 1 shown in FIG. 1 is a double-sided display type product display fixture that is installed in a store such as a department store, a supermarket, a convenience store, etc., and can display products on both front and rear surfaces. 1, three support members 10 in FIG. 1, a plurality of brackets connected to the front and rear surfaces of each support member 10, four brackets 12 per one side in FIG. 1, and two adjacent members The shelf plate 14 placed and fixed over the pair of brackets 12 respectively connected to the same height position of the column members 10 and the central position of the opposing side surface portions of the two adjacent column members 10. It mainly comprises a backboard 16 arranged. In FIG. 1, in order to show the arrangement state of the bracket 12, the fourth shelf board 14 on the left side of the front surface of the fixture 1 is shown before being placed and fixed.

  A support member 10 shown in FIG. 2 has a structure suitable for use in the commodity display fixture shown in FIG. 1, and is a bracket that supports the shelf board 14 when viewed in a state of being incorporated in the commodity display fixture 1 shown in FIG. 12 for connecting and engaging the front and rear surfaces 20 and 22 with a plurality of locking holes 18 formed at intervals in the vertical direction to enable engagement and fixation of the front and rear portions 20 and 22 respectively. The pair of side surface portions 24 and 26 is formed in a substantially square tubular shape.

  Here, the column member 10 has a shape of “substantially rectangular tube” in which the cross section is not only a rectangular tube shape such as a rectangle, but an elliptical shape with four vertices rounded. This is to include an oval shape such as a curved surface shape as well as a flat side surface portion. In addition, since the front surface part and the rear surface part of the support | pillar member 10 are parts which engage and fix the bracket 12, it is preferable to set it as a planar shape.

  And the main feature on the structure of the present invention is that the column member 10 constituting the commodity display fixture 1 is composed of a plurality of plate members (for example, in the column member 10 shown in FIG. The joined body 32 is formed by combining a total of four plate members 28, 28, 30, 30, each of two types of plate members 28, 30. The thickness of each part of the pair of side surface parts 24 and 26 is appropriately adjusted. More specifically, the column member 10 is a single plate member 28 among the parts constituting the side surface parts 24 and 26. The thickness t1 of the portion consisting only of the thickness is made to be less than the thickness t2 of the portion constituting the front surface portion 20 and the rear surface portion 22, and by adopting this configuration, the strength (particularly the cross-sectional performance) is obtained. Material use without maintaining or significantly reducing To effectively reduce, it is possible to reduce the material cost and weight.

That is, in the column member 10 of the present invention, the thickness t2 of the portion constituting the front surface portion 20 and the rear surface portion 22, which is the portion on which the load of the product placed on the shelf board 14 acts, is not reduced (thick). The strength (particularly the cross-sectional performance) is substantially reduced by adopting a configuration in which only the thickness t1 of the portion constituting the pair of left and right side portions 24 and 26, which is a portion where the load of the product does not act, is reduced. Thus, the present invention was completed by successfully reducing the amount of material used and reducing the material cost and weight while maintaining the target.

  Further, the relationship between the thickness t1 and the thickness t2 varies depending on the maximum load load required for the commodity display fixture 1, but for example, the maximum load load applied to one shelf board is 400 to 800 kgf. In the case of the commodity display fixture 1 which is about, the thickness t1 is preferably reduced by 30 to 80%, more preferably by 40 to 70%, and by 50 to 60% with respect to the thickness t2. However, it is preferable from the viewpoint of effectively reducing the amount of material used while maintaining the strength.

  Further, the support member 10 of the present invention has a pair of side surface portions 24 and 26 extending in the center portion along the longitudinal direction L of the support column member 10 and recessed in a direction close to each other. The strut member 10 has a contact portion 36 of a pair of side surface portions 24, 26 at a position immediately below the vertical grooves 34, 34, and the contact portion 36. It is composed of two divided tubular portions 38 and 40 located on both sides in the front-rear direction F with the backboard 16 being connected to the pair of side surface portions 24 and 26 without adding new attachment parts. It is attached between the longitudinal grooves 34, 34, and the strength of the side surfaces 24, 26 is increased by bringing the inner surfaces of the pair of side surfaces 24, 26 into contact with each other at the positions of the longitudinal grooves 34, 34. It is preferable at the point which the intensity | strength of the member 10 improves. Even if the abutting portion 36 is only in a state of being in contact with each other, the effect of improving the strength of the side surface portions 24 and 26 can be obtained. However, the contact portion 36 is linear (continuous) by pressure welding such as caulking joining or welding. ) Or dot (partial) bonding is more preferable.

  Furthermore, it is preferable that the thickness t2 of the part which comprises the front part 20 and the rear surface part 22 is the same over the whole surface. By configuring in this way, the front part 20 and the rear part 22, which are parts to which the product load is applied, have a uniform strength (rigidity) throughout, so that the front part 20 and the rear part 22 are caused by the product load. As a result, it is possible to suppress a part of the member from being locally deformed and to uniformly support the product load on the entire front surface 20 and the rear surface 22 (entire surface). ).

  In the present invention, the “thickness t1 of a portion made of only a single plate material among the portions constituting the side surface portion” refers to a portion where a plurality of plate materials 28 and 30 overlap (for example, a joint portion between plate materials or Specifically, in the case of the column member 10 shown in FIG. 2 and FIG. 3, it means a portion that constitutes the side surface portion only by the plate material 28.

  Moreover, the support | pillar member 10 shown in FIG. 2 has shown the case where it sees in the cross section, and is comprised by the back-and-front symmetry and the left-right symmetry. This is because, when the support member 10 is manufactured with a roll-formed plate material, it is likely that the back-and-forth and left-right symmetry are configured so that distortion due to the springback is less likely to occur. This is preferable because it is easy or can be omitted.

Furthermore, the plurality of plate members constituting the column member 10 of the present invention includes two first plate members 28 and 28 constituting each of the pair of side surface portions 24 and 26, and the front surface portion 20 and the rear surface portion 22. The main surface portion 42 constituting each of the main surface portions 42 and extending from both side ends of the main surface portion 42 in a direction substantially orthogonal to the main surface portion 42 are joined to the respective side end portions of the two first plate members 28, 28. It is composed of both arm portions 44 and 44 constituting the side surface portions 24 and 26, and is a total of four plate members including two second plate members 30 and 30 having a substantially U-shaped cross section as a whole. Is preferred. With this configuration, it is easy to set the thickness t2 of the front surface portion 20 and the rear surface portion 22 and the thickness t1 of the pair of side surface portions 24 and 26 to desired thicknesses, respectively. The amount used can be effectively reduced.

The column member 10 having the structure shown in FIGS. 2 and 3 is the first embodiment, and the two second plate members 30 and 30 of the support member 10 are substantially U-shaped inward. The two arm portions 44, 44 of the second plate member 30 are arranged in the direction and are joined on the outer surfaces of the side end portions 28a, 28a of the two first plate members 28, 28 facing each other. have.
Further, in FIG. 2, there is no step formed on the outer surface of the side surface portion of the column member 10 at the position where the first plate member 28 and the second plate member 30 are joined, and the appearance after welding or painting is cleaned. The side end portion 28a of the first plate member 28 on which the arm portion 44 of the second plate member 30 is overlapped is formed as a stepped portion 46 that is stepped down to the inner surface side by the thickness of the second plate member 30. However, such a configuration can be adopted as necessary.

  In addition, as a method of joining the 1st board | plate material 28 and the 2nd board | plate material 30, various welding techniques, such as TIG welding, YAG laser welding, fiber laser welding, spot welding, are mentioned, for example, but linear (continuous) A welded portion may be formed on the surface, a welded portion may be formed in a spot (partial) manner, and other joining techniques may be used. Among the welding methods listed above, fiber laser welding, in particular, can weld thin parts deeply, and the welding surface is clean and the welding speed can be increased. It is suitable for manufacturing.

  The column member 10A having the structure shown in FIG. 4 and FIG. 5 is the second embodiment, and the two second plate members 30 and 30 are arranged in a direction in which the substantially U-shape is directed outward. The both arm portions 44, 44 of the second plate member 30 have a configuration in which the arms are overlapped and joined to the inner surfaces of the side end portions 28a of the two first plate members 28, 28 facing each other. .

  In FIG. 4, the joint strength between the first plate member 28 and the second plate member 30 is increased, the aesthetics are improved, and safety is ensured (with respect to the direction of the force on which the load is applied to the shelf plate 14). The second plate member 30 has a structure that is difficult to be separated from the end portion of the joined first plate member 28.) From the viewpoint of the above, the side end portion 28a of the first plate member 28 is the second plate member 30. The case where it comprises so that it may further have the folding | turning part 48 folded back so that both surfaces of the arm part may be wrapped is shown.

  The column member 10B having the structure shown in FIG. 6 and FIG. 7 is the third embodiment, and the two third plate members 50, 50 are rotated 180 degrees with respect to each other when viewed in cross section. In this way, they are superposed and joined. With this configuration, the strut member 10B is thicker because the thickness t2 of the front surface portion 20 and the rear surface portion 22 is a portion where the two third plate members 50, 50 overlap each other, while the pair of side surface portions 24 is provided. , 26, the thickness t 1 of the portion consisting of only one third plate member 50 can be set to half the thickness of the front surface portion 20 and the rear surface portion 22.

  As described above, the column member of the present invention particularly has a product load (for example, a load applied to one shelf plate attached to one of the front surface portion and the rear surface portion of the column member is 400, for example, Since it has a structure capable of withstanding a load of about 800 kgf), it is installed in a store such as a department store, a supermarket, or a convenience store, and is suitable for configuring a commodity display fixture for displaying and selling commodities.

What has been described above is merely an example of an embodiment of the present invention, and various modifications can be made within the scope of the claims. For example, although the above-mentioned embodiment showed the case where the support | pillar members 10, 10A, and 10B were comprised combining 2 or 4 board | plate materials, the support | pillar member 10 was comprised combining 3 or 5 or more board | plate materials. You can also As an example of configuring the column member 10 by combining three plate members, the first plate member is formed into a rectangular tubular member by roll forming and butt welding, and the thickness is increased at portions corresponding to the front surface portion and the rear surface portion. For this reason, there is a method in which the second plate members are overlapped and joined. Further, the column members 10, 10A, 10B of the present invention include a plurality of vertical members so that the product placement area on the shelf plate can be expanded by arranging the shelf plates 14 of the product display fixture side by side. Although the case where two locking hole rows having the locking holes 18 are provided is shown, if such a case is not assumed, only one row may be provided. Furthermore, the column members 10, 10A, and 10B of the present invention are suitable for constituting a double-sided display type product display fixture, but it goes without saying that they can also be used when constituting a single-sided display type product display fixture.
