Description

  The present invention relates to a panel having a structure useful for thinning.

This type of panel is usually constructed by arranging a pair of face materials facing each other. At that time, for the purpose of hiding the edge of the face material and securing the strength in the thickness direction, as shown in FIG. , B is formed into a symmetrical shape, and the end surface is processed by inserting the leg portion e of the edge member d into the gap c generated between the bent portions b and b when the face materials a and a are bonded to each other. I try to do it. Patent Documents 1 and 2 can be exemplified as those having such a structure.

  However, with such a structure, since there is a limit to the bending dimension of the U-shaped bent portion b, it is difficult to manufacture a panel that is thinner than a certain level. Moreover, since the gap | interval c when the bending parts b and b face each other is located in the thickness direction center of a panel in any side and the leg part e of the edge member d is inserted here, as shown in FIG. If the corner portion is left as it is, the legs e and e interfere with each other. For this reason, it is necessary to further process the leg e from the state shown in the figure, which causes a problem of increasing costs.

  The present invention has been made paying attention to such a problem, and provides a panel having a new structure that can easily cope with the thinning and eliminates the need for special preparation for the edge member. The purpose is that.

  In order to achieve this object, the present invention takes the following measures.

  That is, the panel of the present invention is configured by arranging a pair of face materials having bent portions on required sides, and any of the face materials on the sides where the bent portions face each other. The bent portion formed by the U-shaped bending is formed so as to face the bent portion formed by hemming bending formed on any of the face materials. In the present specification, “hemming bending” refers to a process of folding an end portion, and is also commonly referred to as “shell folding”.

  According to such a structure, the edge of the face material can be concealed by the bent portion at any side where the bent portions face each other, and there is a bent portion due to the U-shaped bending, so that the panel thickness Directional strength can also be ensured. And since the folded part by hemming bending takes a relatively flat form, if this is faced to the folded part by U-shaped bending, it is compared with the case where the folded parts by U-shaped bending are faced to each other. It is possible to reduce the panel thickness dimension to near half.

  As a structure that does not cause unevenness in strength or the like between the face materials, one of the face materials has a bent portion formed by a U-shaped bend on the first side of the two sides intersecting at a predetermined corner portion. A bent portion by hemming bending is formed on the other side material, and a bent portion by hemming bending is formed on the first side of the two sides that intersect at the corner portion corresponding to the corner portion, Each of the second sides is formed with a bent portion by U-shaped bending, and when the double-sided materials are faced to each other, the bent portion by the U-shaped bending and the bent portion by Hemming bending face each other. It is desirable that the grooves formed between the bent portions are displaced in the opposite direction from the panel center along the panel thickness direction on the two sides.

  In order to effectively realize the above-described structure over the entire circumference of the panel, a bent portion by U-shaped bending is formed on the first facing two sides of one face material, and hemming bending is performed on the second facing two sides. Each of the bent portions is formed, a bent portion by hemming bending is formed on the corresponding first opposing two sides of the other face material, and a bent portion by U-shaped bending is formed on the second opposite two sides, respectively. It is effective to keep it.

  In order to eliminate the need for special preparation for the edge member, the edge member is concealed from the edge body by concealing the end face where the bent part by the U-shaped bending and the bent part by the hemming bending face each other. A pair of edge members configured so that protruding leg portions are inserted into grooves formed between the two bent portions and intersecting at the corner portions are formed along the panel thickness direction with respect to the edge body. It is preferable to set the relationship so as to be displaced in the opposite direction from the center.

  In order to effectively reduce the number of parts, a long member with an equal cross-section such as extruded material is used as the edge member, and the common long member is inverted and used for the edge members on both sides that intersect at the corner. It is suitable.

  As described above, in the present invention, when face materials are arranged to face each other, a combination of U-shaped bending and hemming bending is combined on each side, so that the conventional one is used without using special equipment. Compared with, thin panel can be easily made. In addition, the relationship between the grooves that occur in the panel edge at the adjacent sides when they are attached is such that one is offset to one side in the panel thickness direction and the other is offset to the other side in the panel thickness direction. Therefore, when the edge members are attached to the four sides, the legs of the edge members do not interfere with each other at the corner portion, and it is not necessary to perform special processing on the edge members, and the manufacturing cost can be effectively reduced.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  The panel of this embodiment is preferably used as a side panel SP of a desk D as shown in FIG. That is, since this type of side panel SP is used as a partition which is arranged on the top plate T and partitions the adjacent work space S as necessary, the side panel SP is as thin as possible so as not to make the top plate surface as narrow as possible. It is desirable to have a form.

  Therefore, in the panel P of the present embodiment shown in FIG. 2, the panel main body pa shown in FIG. 5 is formed by bonding the pair of face materials 1 and 2 in a face-to-face state. The panel is made thin by using the bent portions 12a and 22b by the U-shaped bending and the bent portions 12b and 22a by the hemming bending in combination.

  More specifically, the face materials 1 and 2 are made of a plastically deformable material such as steel, and one face material 1 has a first opposing side of the face plate portion 11 serving as a panel surface. Bending portions 12a and 12a are formed by bending the upper and lower sides 11a and 11a which are (opposing two sides) by bending twice, and the left and right side sides 11b which are second opposing sides (opposing two sides), 11b is formed with bent portions 12b and 12b which are folded back almost flat using hemming bending. Further, in the other face material 2, similarly to the upper and lower sides 21 a which are first opposing sides (opposite two sides) corresponding to the first opposing sides 11 a and 11 a in the face plate portion 21 serving as a panel surface. Bending portions 22a and 22a are formed by hemming bending, and bending portions 22b and 22b are formed by left and right side sides 21b and 21b, which are second opposing sides (opposing two sides), respectively. . In that case, for example, as shown in an enlarged view in the vicinity of the upper left corner portion in FIG. 3, the bent portions 12b and 22a by hemming bending are formed up to positions where the corner portions P of the face plate portions 11 and 21 are formed. The ends of the bent portions 12a and 22b formed by the U-shaped bending are positioned at a position separated from the corner portion P by a distance d so as not to interfere with each other.

  Then, as shown in FIG. 4, by bonding the double-sided materials 1 and 2 at the facing position, the folded portion 12a (22b) by mutual U-shaped bending and the folded portion 22a (12b) by hemming bending are formed. They are facing each other to the extent that they meet. At this time, grooves 1a and 1b are formed between the bent portions 12a and 22a, and 12b and 22b, respectively, and these grooves 1a and 1b are hemming bent at the panel upper end surface (and the panel lower end surface). The face plate portion 11 of the one face member 1 is formed at a position close to the face plate portion 21 of the other face member 2 on which the bent portion 22a is formed, and the bent side portion 12b is formed on the panel side end face by hemming bending. It is formed at a position close to.

  On the other hand, as shown in FIG. 5, the edge member 3a mounted on the upper end surface of the panel (and the lower end surface of the panel) uses a long member 31 having an equal cross section whose cross section is substantially T-shaped by aluminum extrusion or the like. The edge main body 31a1 having a size that conceals the upper end surface of the panel formed by the bent portions 12a and 22a of the double-sided materials 1 and 2 and a leg portion 31a2 protruding from the back surface of the edge main body 31a1 are integrally provided. The position of the leg portion 31a2 is set to a position displaced (offset) toward the face plate portion 21 side of the other face member 2 along the panel thickness direction with respect to the center in the width direction of the edge body 31a1. And this edge member 3a is attached to the upper end surface of the said panel main body pa by driving this leg part 31a2 into the groove | channel 1a displaced in the same direction.

  Further, the edge member 3b mounted on the panel side end surface uses the same long member 31 as described above, and conceals the side end surface formed by the bent portions 12b and 22b of the double-sided materials 1 and 2. The edge body 31b1 and a leg 31b2 projecting from the back surface of the edge body 31b1 are integrally provided, and the position of the leg 31b2 is one surface along the panel thickness direction with respect to the center of the edge body 31b1 in the width direction. It is set at a position displaced (offset) to the face plate 11 side of the material 1. And this edge member 3b is attached to the side end surface of the said panel main body pa by driving this leg part 31b2 into the groove | channel 1b displaced in the same direction. That is, both the edge members 3a and 3b have a relationship in which the common long member 31 is cut to a required length and one is inverted with respect to the other.

  In addition, when the face materials 1 and 2 are bonded together, a core material is attached to the inner surface of one or both of the face materials 1 and 2 between the face plate portions 11 and 21 so that the inside becomes dense as necessary. You may make it stick.

  As described above, in the present embodiment, when the panel P is formed by arranging the pair of face materials 1 and 2 facing each other, one face material 1 has two sides 11a and 11b intersecting at a predetermined corner portion. A bent portion 12a by U-shaped bending is formed on the first side 11a, a bent portion 12b by hemming bending is formed on the second side 11b, and the other face material 2 corresponds to the corner portion. Of the two sides 21a and 21b intersecting at the corner portion, a bent portion 22a by hemming bending is formed on the first side 21a, and a bent portion 22b by U-shaped bending is formed on the second side 21b, respectively. When the two faces each other, the bent portion 12a (22b) by U-shaped bending and the bent portion 22a (12b) by hemming bending face each other, and are formed between the bent portions 12a and 22a. Groove 1a, bent 12b, a groove 1b formed between 22b is obtained by such a state of being displaced in the opposite direction from the panel center along the panel thickness direction.

  With such a structure, in any side 11a, 21a, 11b, 21b where the bent portions 12a, 22a, 12b, 22b face each other, the face material 1 is formed by the bent portions 12a, 22a, 12b, 22b. 2 can be concealed, and the presence of the bent portions 12a and 22b by the U-shaped bending effectively ensures the strength in the panel thickness direction. Since the bent portions 12b and 22a by hemming bending have a flat shape, if they are faced to the bent portions 22b and 12a by U-shaped bending, they are folded by the U-shaped bending as shown in FIG. As compared with the case where the curved portions are faced to each other, it is possible to reduce the panel thickness dimension to approximately half.

  Further, since both of the face materials 1 and 2 are provided with bent portions 12a and 22b by U-shaped bending and bent portions 12b and 22a by hemming bending, they are biased to either of the face materials 1 and 2. Compared to the case where the panels are distributed, the face materials 1 and 2 can be made to be in an equal relationship, and the entire panel can be balanced.

  More specifically, the bent portions 12a and 12a by the U-shaped bending are formed on the first opposing two sides 11a and 11a of one face material 1, and the bending by the hemming bending is performed on the second opposing two sides 11b and 11b. Forming portions 12b and 12b, respectively, and bending portions 22a and 22a by hemming bending to corresponding first opposing two sides 21a and 21a of the other face material 2 are connected to second opposing two sides 21b and 21b. Since the bent portions 22b and 22b are formed by bending the U-shape, the folded portion 12a (22b) by the U-shape bending and the bent portion 22a (12b) by the hemming bending are faced to the four sides of the panel. The structure can be realized appropriately.

  Further, the edge member 3a (3b) is concealed by the edge member 3a (3b) shown in FIG. 3b) is configured such that the leg portion 31a2 (31b2) protruding from the edge body 31a1 (31b1) is inserted into the groove 1a (1b) formed between the bent portions 12a and 22a (between 12b and 22b). Of the pair of edge members 3a and 3b that intersect at the corner, the edge member 3a displaces the leg 31a2 from the panel center to one side along the panel thickness direction with respect to the edge body 31a1, and the edge member 3b The leg 31b2 is displaced from the center of the panel to the other along the panel thickness direction with respect to the main body 31b1. Thus, since the offset positions of the leg portions 31a2 and 31b2 in the corner portion are different, interference between the leg portions 31a2 and 31b2 is effectively avoided as shown in FIG. 6, and the edge members 3a and 3b are avoided. Therefore, it is possible to effectively avoid a cost increase by eliminating the need for special preparation.

  Further, a long member 31 having an equal cross section such as an extruded material is adopted for the edge members 3a and 3b, and the long member 31 common to both edge members 3a and 3b intersecting at the corner is reversed. Therefore, it is possible to effectively reduce the cost by reducing the number of parts.

The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the side where the bent parts face each other, it has a structure in which a bent part formed by U-shaped bending on one of the face materials and a bent part formed by hemming bending formed on any of the face materials face each other. If it is, it is not necessarily limited to the above.

  Therefore, even if the bent part by the U-shaped bending is concentrated on any one of the face materials and the bent part by the hemming bending is concentrated on the other, it is intended to reduce the thickness when facing each other. The purpose of can be achieved effectively.

  Alternatively, the bent portions do not necessarily have to be a pair. For example, in the case where the panel is supported by a support rod standing on the desk, the bent portions are at least on the upper side and the side side of the panel. It is also possible to adopt a form in which the lower side is opened and the support rod is inserted into the inside while facing each other.

  Furthermore, it is not always necessary to continuously form the bent part by the U-shaped bending and the bent part by the hemming bending at each side, and even if they are formed intermittently, the same effect can be obtained. Is possible.
