Description

[Detailed Description of the Invention] The present invention is a structural unit of a panel that can efficiently display products and store various assembly parts. The present invention relates to an add-on panel unit for locking an article holder, which is integrally constructed as a whole with a thin plate-like body having interlocking connecting portions.

This type of panel unit can be assembled by adding as many panels as needed to assemble a panel with a desired area, or by assembling multiple types of panel units with different shapes of article holder locking parts, panel widths, colors, patterns, etc. It has a wide range of applicability depending on the purpose of use, as it can be used to create diversity by adding pieces together.
It has the advantage of being easy to provide at low cost based on mass production. Roll-forming is the most rational means of production, but conventional panel units have little symmetry between their interdigitated connections, which is the main reason for shrinkage during roll-forming. Distortion and elongation distortion tend to be unevenly distributed in the lateral direction with respect to the feeding direction, causing warping and abnormal unevenness in the finished product, which not only makes it difficult to connect as expected, but also makes it difficult to maintain a beautiful appearance. It was also hot.

Also, when panel units are connected to each other by interfitting type connecting parts, when the connected panel units are viewed from the front side of the panel, the connecting points are not visible, making it appear as if they were one panel. It is desirable to be able to see it. In other words, by doing so, you can make the exterior look beautiful.

Furthermore, when forming a panel by connecting panel units with each other through interfitting type connecting parts, it is sometimes desirable to have a locking part for the article holder at the connecting part, and this has been the case for some time. It is also being done in the form of As for the locking portion, one having a C-shaped cross section along the width direction of the panel is suitable for locking various types of article holders; It is desirable to have a stop part.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to avoid uneven distribution of distortion during roll forming as much as possible, and to produce high-quality, high-precision products with no or very little warping or abnormal unevenness. product, and the connecting points between panel units can be
It is possible to make it invisible when viewed from the front side of the panel, and furthermore, it is suitable for locking various types of article holders at the connection points between panel units.
The object of the present invention is to provide a refillable panel unit for locking an article holder, which can be provided with a square-shaped locking part.

The feature of the add-on type panel unit for locking an article holder according to the present invention is that the interfitting type connecting portions provided over the entire length of the panel are provided at each of the opposing ends.
a bottom wall portion that recesses toward the other connecting portion that faces the end edge of the panel surface portion located between them, and a side plate portion that continues from the bottom wall portion and extends in a direction away from the other connecting portion; The extending end of the side plate part has a bending plate part that is continuously bent toward the front side of the panel surface, and is configured so that one side fits inside the other. And the effects are as follows.

In other words, if the connecting parts consisting of the bottom wall part, the side plate part, and the bent plate part are fitted together so that one part encloses the other part, the connecting part will have a C-shaped cross-sectional shape along the panel width direction. A stop will be formed.

Then, from the front side of the panel, the edge of the connecting part on the side to be included, that is, the tip of the folded plate part, is positioned on the back side of the edge located between the two connecting parts. can be made invisible,
The edge of the outer connecting part, that is, the tip of the bent plate part, can be positioned on the back side of the connecting part on the side to be included so that it cannot be seen from the front side of the panel. As a result, the connection points between the panel units can be made invisible when viewed from the front side of the panel.

In addition, each of the two connecting parts consists of a bottom wall part, a side plate part, and a bent plate part, and since one includes the other, although there are differences in size, the panels When viewed as a cross-sectional shape along the width direction, it exhibits a symmetrical shape. For this reason, when roll forming, which is the most rational production method, is adopted, the shrinkage strain and elongation strain during roll forming will be distributed almost uniformly in the lateral direction to the feeding direction, and distortion will occur. Because the balance is almost maintained in the lateral direction (width direction) of the object, the finished product has very little or no warping or abnormal unevenness, which results in high-quality, high-precision products. It can be done.

Therefore, as a whole, it is possible to provide a C-shaped locking part suitable for locking various types of article holders, and to eliminate warpage and unevenness of the panel unit, and to improve the connection. This makes it possible to make the location invisible when viewed from the front side of the panel, and also improves manufacturing precision, allowing both connecting parts to connect properly as expected, and ensuring the connection strength itself is as expected. In addition, it is possible to perform the locking action of the article holder as expected, and thus to obtain an add-on panel unit for locking the article holder, which has great practical advantages. I've reached it.

Embodiments of the present invention will be described below based on the drawings.

The add-on type panel unit P has interfitting type connecting parts A and B extending over the entire length of the panel at each of the opposing ends, and the whole is constructed as a series of thin plate-like bodies. , both the connecting parts A and B,
In the compatible posture, both connecting parts A and B expose the locking part C of the article holder E, and the cross-sectional shape along the panel width direction passes through the panel width center line and is perpendicular to the panel surface. The basic structure is that the panel surface portion D between the connecting portions A and B is approximately symmetrical with respect to the plane F.The specific structure will be described in detail below. (i) The other connecting portion B continues to face the edge portions Da and Db of the flat panel surface portion D; , bottom plate portions A ₁ and B ₁ that are depressed toward the A side and form opposite bottom walls of the locking portion C; (ii) the other connecting portion B following the bottom plate portions A ₁ and B ₁ ; , side plate portions A ₂ and B ₂ extending parallel or substantially parallel to the flat panel surface portion D in a direction away from A and forming a back wall of the locking portion C; (iii) the side plate portion A; ₂ , a bent plate portion that is bent toward the front side of the panel surface following the extending ends of _B2 and engages with the bottom plate portions _B1 and _A1 of the other connecting portions B and A;
A ₃ , B ₃ , and one side connecting part B
are configured to fit together in a state that includes the connecting portion A on the other side. The above points apply to both Fig. 2 (Fig. 1) and Fig. 3. In the case of the one shown in FIG. 2, (a) the double bent plate portions A ₃ and B ₃ are respectively connected to the side plate portions A ₂ and
B _{2 is} bent _at an angle _{of 180} degrees or _close to _it ; Bent plate part A ₃ , B ₃
It is formed in a symmetrical or nearly symmetrical shape.

On the other hand, in the case of the one shown in FIG. 3, both bent plate portions A ₃ and B ₃ are bent at an acute angle close to 90 degrees.

In the illustrated example, the lower connecting portion B of the upper panel unit P includes the upper connecting portion A of the lower panel unit P, but the configuration may be reversed. Further, it may be used in a state where it is upside down from that shown in the drawing. Normally, the usage mode is to position the panel surface in a vertical plane with the longitudinal direction of the connecting parts A, B and the locking part C set in the horizontal direction, but depending on the structure of the article holder E, , the longitudinal direction of the connecting parts A and B may be the vertical direction, or they may be attached along the lower surface of the ceiling.

The panel unit P usually continuously unwinds a thin, flat and long metal strip (rolled on a drum), using a large number of roll groups, from the center of the strip to both outer sides. It is produced by bending (roll forming) and then roll forming a strip plate that is cut to the required size in the final process.

The panel units P and P may be connected to each other by only mutually fitting the connecting portions A and B, or by using adhesive or welding together.

Now, when comparing the one shown in FIG. 2 and the one shown in FIG. 3, the former is superior to the latter in terms of the precision of the locking part C and the load-bearing performance under load. Further, the latter is superior to the former in terms of ease of roll forming and workability. Of course, all of them are far superior in terms of ease of roll forming and workability compared to conventional ones. In addition, the quality of roll forming is determined by changing the ratio of the total occupied width of connecting parts A and B to the occupied width of flat panel surface part D for a metal strip plate of a constant width by changing the processing roll. Another advantage is that it can be easily adjusted and product diversification can be economically advantageous.

Although it may be a special case, the add-on panel unit P may be made by performing roll forming on a band-shaped plate made of synthetic resin.

Needless to say, the illustrated article holder E
This is merely an example, and the panel unit of the present invention is not limited to any type of article holder.
