Description

  The present invention relates to a joining structure for joining two or more members.

  Various handles are provided on a front plate of a drawer or a door storage, and among them, there is a line handle (also referred to as a handle) extending linearly along an edge of the front plate. The line handle is preferred because it does not protrude to the front of the storage, and a line is formed in the width direction of the storage to provide an accent in design. As a line handle, for example, a long member that is folded back so that a finger can be put thereon as in Patent Document 1 is widely known.

JP 2008-104554 A

  The front plate (front plate for storage) arranged on the front surface in the storage is the member most observed by the user, and thus has the greatest influence on the aesthetic appearance of the storage. In particular, if the handle is more conspicuous than necessary on the front panel, or if there is no sense of unity with the front panel, the aesthetic appearance of the entire storage is impaired, and the user feels uncomfortable. For this reason, not only the functionality but also the design of the handle provided on the front plate for storage, such as the line handle, are regarded as important.

  As a method of improving the design of the line handle, it is conceivable to color the line handle according to the front plate. However, if the entire line handle is made the same color as the front plate, the visibility of the line handle is reduced. Then, there is a possibility that the position of the line handle is difficult to understand at the time of use, or the accent on the design is lost.

  Next, it is conceivable to color a part of the line handle, particularly a part covering the end surface of the front plate, in the same color as the front plate. However, the line handle is generally manufactured by extruding an aluminum alloy. Aluminum is colored by alumite treatment. However, since alumite treatment is a treatment immersed in a strong acid, it is difficult to partially apply alumite treatment.

  Further, it is conceivable to make a part of the line handle, particularly a part covering the end face of the front plate, match the color and the material with the front plate. However, when combining a plurality of members, high coupling strength is required so that the plurality of members do not come off when the storage is pulled out. From these facts, at present, as in Patent Document 1, the line handle is generally constituted by a single member and generally has a metallic color as a whole.

  The present invention has been made in view of the above problems, and has as its object to provide a member connecting structure capable of firmly connecting two or more members.

  In order to solve the above-mentioned problem, a typical configuration of a connecting structure of members according to the present invention is a connecting structure of two or more members, a base member having a hole, and an insertion portion inserted into the hole. The additional member and the base member are integrated by deforming the edge of the hole of the base member and caulking the insertion portion of the additional member.

  According to such a configuration, two or more members made of the same or different materials to be joined can be firmly joined. At this time, with the bonding structure of the present invention, a higher bonding strength can be obtained than when an adhesive is used, and since no adhesive is used, a decrease in the bonding strength due to aging can be prevented.

  In the connection structure of the present invention, two or more members can be connected without using components such as screws and bolts. Therefore, since the heads of the screws and bolts do not protrude, the appearance after the connection can be improved. Since there is no need to form a hole for inserting a screw or a bolt, it is not necessary to secure a thickness for forming such a hole in a member that is symmetrically coupled. For this reason, it is possible to satisfactorily join even if the joining target is a thin member.

  Further, as compared with a rivet (a caulking using a pin), there is no need to secure a thickness for piercing the pin, so that even a thin member can be satisfactorily joined as described above. And since it is not necessary to grind the remaining margin of the pin after caulking, the working process can be simplified.

  The hole is preferably in the form of a pocket that does not penetrate. According to this configuration, in the base member, the coupling structure is not exposed on the side opposite to the side to which the additional member is coupled. Therefore, it is possible to improve the appearance after the connection.

  It is preferable that one of the opposing surfaces of the hole and the insertion portion has a convex shape and the other has a concave shape. Thereby, it is possible to prevent the hole portion after caulking from being displaced from the insertion portion, and to increase the bonding strength.

  In the insertion portion, an inclined surface that is longer toward the inner side of the hole may be formed at a position corresponding to an edge of the hole that is deformed. Thus, when the insertion portion is swaged in the hole, the edge of the hole abuts on the inclined surface. Therefore, it is possible to further increase the bonding strength between the base member and the additional member.

  The base member and the additional member are extruded long members, and the holes are formed by extrusion, and the edges of the holes may be deformed by post-processing. For example, when connecting long members by screwing as in the conventional case, the long members are connected at several places with an interval. On the other hand, in the coupling structure of the present invention, a groove-shaped hole is formed by extrusion, and the base member and the additional member are coupled over the entire width by caulking the insertion portion of the additional member in the hole. be able to. Therefore, the long member can be more firmly joined than other joining structures, and it is possible to prevent the joining strength from varying in the width direction.

  The base member may be aluminum or an aluminum alloy, and the additional member may be aluminum or an aluminum alloy colored in a different color. For example, when stainless steel is used as the base member, the hardness is high. Therefore, when a load is applied so that the edge of the hole is deformed when the base member and the additional member are joined by caulking, the entire base member may be deformed. is there. On the other hand, since aluminum is a relatively soft material, the edge of the hole of the base member can be deformed by post-processing. In addition to aluminum, brass is conceivable, but aluminum is preferred because it is less likely to corrode.

  Further, in the above configuration, even when aluminum or an aluminum alloy is used for both the base member and the additional member, they can be colored in different colors in advance because they are separate members. Therefore, it is possible to enhance the design of the articles joined by the joining structure.

  The base member may be aluminum or an aluminum alloy, and the additional member may be a resin material. By using different materials for the base member and the additional member as described above, it is possible to enhance the design of an article constituted by the members joined by using the joint structure of the present invention.

  ADVANTAGE OF THE INVENTION According to this invention, the connection structure of the member which can couple two or more members firmly can be provided.

It is a whole perspective view of a kitchen. It is a perspective view of the drawer of the cabinet of FIG. It is a figure explaining the line handle concerning this embodiment. It is sectional drawing in the AA position of FIG.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the specification and the drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted. Note that dimensions, materials, and other specific numerical values shown in the following embodiments are merely examples for facilitating understanding of the present invention, and do not limit the present invention unless otherwise specified.

  FIG. 1 is an overall perspective view of the kitchen 100. As shown in FIG. 1, the kitchen 100 is provided with a plurality of cabinets 100a such as stove cabinets and sink cabinets and a plurality of storages such as hanging cabinets 100b.

  FIG. 2 is a perspective view of the drawer 110 of the cabinet 100a of FIG. As shown in FIG. 2, the drawer 110 includes a front plate 112 forming a front surface, a side plate 114 forming a side surface, a bottom plate 116 forming a bottom surface, and a back plate 118 forming a back surface. A line handle 200 for opening and closing the cabinet 100a is provided on the upper end side of the front plate 102 among them.

  FIG. 3 is a diagram illustrating the line handle 200 according to the present embodiment, and FIGS. 3A and 3B both show a state where the vicinity of the line handle 200 of the drawer 110 in FIG. 2 is enlarged. FIG. 4 is a cross-sectional view taken along the line AA in FIG. 3A, and FIG. 4A illustrates a state before the additional member 210 and the base member 230 are integrated. (B) illustrates a state where the additional member 210 and the base member 230 are integrated.

  As shown in FIGS. 3A and 3B, the line handle 200 of the present embodiment includes two members, an additional member 210 and a base member 230. In the connection structure of the present embodiment, a case where the additional member 210 and the base member 230 of the line handle 200 are connected as two or more members is exemplified. However, the present invention is not limited to this, and the connecting structure of the present embodiment can be applied to a case where two or more members of an additional member and a base member constituting an article other than the line handle are connected.

  As shown in FIG. 4A, the additional member 210 is configured to include an end face cover portion 212, a front hanging portion 214, and a hanging portion 216 which is an insertion portion inserted into a hole 236 described later. The end face cover portion 212 is a face that covers the end face 112a (see FIGS. 2 and 3) of the front plate 112. A front hanging portion 214 extends from the front end of the end face cover portion 212 along the front side (front surface 112b) of the front plate 112. A rearward portion 216 extends from the rear end of the additional member 210 along the rear side (rear surface 112c) of the front plate. Since the end face cover portion 212, the front hanging portion 214, and the rear hanging portion 216 are continuous, the additional member 210 has a U-shape with one side opened.

  Further, a convex portion 218 that protrudes toward the opposite side to the hanging portion 216 is formed on the hanging portion 216 side of the end surface cover portion 212. The end face cover portion 212, the hanging portion 216, and the convex portion 218 have a T-shape.

  The base member 230 includes a front plate attaching portion 232, a handle portion 234, and a hole 236. The front plate attachment portion 232 is a surface fixed to the rear surface 112c of the front plate 112. The handle portion 234 extends outside the front plate 112 (upward in FIG. 4) from the front plate attachment portion 232.

  The handle 234 includes an upper extension 234a, a front extension 234b, and a handle 234c. The upper extension portion 234a extends upward from an upper end of the front plate attachment portion 232, and a front extension portion 234b extends forward from the upper end. From the front end of the front extension portion 234b, a handle portion 234c that is inclined downward toward the front extends. Since the upper extension portion 234a, the front extension portion 234b, and the handle portion 234c are continuous, the handle portion 234 has an inverted-J shape. On the front plate side of the front plate attachment portion 232, a hole 236 is formed by recessing the front plate attachment portion 232 backward.

  When connecting the additional member 210 shown in FIG. 4A to the base member 230, first, the backward portion 216 and the convex portion 218 are inserted into the hole 236, and the backward portion 216 and the convex The part 218 is swaged in the hole 236. More specifically, when the wedge 240 is inserted into the edge 232a of the hole 236 and deformed, the recess 220 is formed by the wedge 240, and the edge 232a of the hole is deformed and the end face of the drooping portion 216 (an inclined surface described later) Surface 216a).

  As described above, according to the connection structure of the present embodiment, the additional member 210 and the base member 230 can be easily and firmly connected, and they can be integrated. Such a connection by caulking can provide a higher strength than a method such as bonding. Further, since no adhesive is used, it is possible to prevent a decrease in bonding strength due to aging. Therefore, the durability of the line handle 200 can be improved.

  Further, according to the above configuration, the two or more additional members 210 and the base member 230 can be combined without using screws or bolts. Therefore, when screws, bolts and the like are used, their heads do not protrude, so that the appearance of the joined members can be improved. Further, since there is no need to form holes such as screw holes, it is not necessary to secure a thickness for forming those holes in a member that is symmetrically coupled. For this reason, it is possible to satisfactorily join even if the joining target is a thin member.

  Further, in a conventional rivet (a caulking using a pin), it is necessary to grind the remaining margin of the pin after caulking. On the other hand, in the connection structure of the present embodiment, since no pins are used, a polishing operation is unnecessary. Therefore, the working process can be simplified. Further, since it is not necessary to secure a thickness for piercing the pin in the member to be joined, it is possible to satisfactorily join even a thin member as described above.

  Further, according to the coupling structure of the present embodiment, materials having different colors and materials can be used for the additional member 210 and the base member 230. Thus, by using different materials for the additional member 210 and the base member 230, or using the same material having different colors, the design of the line handle 200, that is, the article connected by the connecting structure of the present embodiment is improved. It becomes possible.

  In the present embodiment, the base member 230 and the additional member 210 are extruded long members. The hole 236 of the base member 230 is formed in a groove shape by extrusion, and the edge of the hole 236 is deformed by post-processing, that is, by forming the recess 220 by the above-described wedge.

  Here, in the case where the long members are joined by screwing as in the related art, it is necessary to carry out the joining at several places with an interval in the longitudinal direction. On the other hand, in the coupling structure of the present embodiment, the long additional member 210 and the base member 230 can be coupled over the entire width by caulking the hole 236 with the hanging portion 216 as an insertion portion. Therefore, a higher bonding strength than the conventional connection by screwing can be obtained.

  As a material of the base member 230 and the additional member 210, aluminum or an aluminum alloy can be suitably used. Since aluminum and aluminum alloys are easily extruded, they are suitable as materials for the line handle 200 manufactured by extrusion.

  If stainless steel is used as the base member 230, the hardness of the base member 230 is high, so that when the edge of the hole 236 is deformed, the entire base member 230 may be deformed. On the other hand, since aluminum is a relatively soft material, the edge of the hole 236 of the base member 230 can be deformed by post-processing. It should be noted that brass can be used in addition to aluminum, but aluminum is preferred because it is less likely to corrode.

  Here, coloring of aluminum is mainly performed by alumite processing, but it is difficult to partially perform alumite processing. Therefore, it is difficult to color one aluminum member with a plurality of colors. However, according to the above configuration, since the base member 230 and the additional member 210 are separate components, each can be colored in different colors. Therefore, even when aluminum or an aluminum alloy is used for both the additional member 210 and the base member 230, it is possible to enhance the design of the joined articles by coloring them in different colors in advance.

  3A and 3B exemplify the lightness and darkness of the color by the density of hatching, the hatching in FIG. 3A illustrates a dark color, and the hatching in FIG. 3B illustrates a bright color. .

  As described above, since the base member 230 and the additional member 210 can be colored in different colors, the additional member 210 is colored in a dark color according to the color of the dark front plate 112 in FIG. I have. On the other hand, in FIG. 3B, the additional member 210 is colored in a bright color according to the color of the bright front plate 112.

  As described above, when the drawer 110 has a line-up of a plurality of colors, the additional member 210 is matched with the color of the front plate 112, and the base member 230 can be set to a common color of the line-up. Thus, it is possible to give a sense of unity in design between a plurality of models.

  Further, among the base member 230 and the additional member 210, aluminum or an aluminum alloy may be used for the base member 230, and a resin material (colored resin) may be used for the additional member 210. Thus, the base member 230 made of aluminum or an aluminum alloy is colored and the additional member 210 is made of a colored resin, whereby the step of coloring the additional member 210 can be omitted. In addition, as the resin, for example, polycarbonate, ABS, and the like can be exemplified, but the resin is not limited thereto, and another resin can be used.

  Further, in the present embodiment, alumite processing has been exemplified as a method for coloring aluminum or an aluminum alloy, but the present invention is not limited to this, and other known coloring methods such as a method using a paint may be employed. . Even in such a case, for example, when a paint is used, a process such as masking is required when one member is colored in a plurality of colors, but according to the line handle 200 of the present embodiment, such a process is required. The color of the base member 230 and the color of the additional member 210 can be easily changed without requiring any special processing.

  FIG. 4 is referred to again. As shown in FIG. 4A, in the coupling structure of the present embodiment, the hole 236 has a pocket shape that does not penetrate. Accordingly, as shown in FIG. 4B, the coupling structure is not exposed on the side of the base member 230 opposite to the side to which the additional member 210 is coupled. Therefore, it is possible to improve the appearance after the connection.

  Further, in the present embodiment, the convex portion 218 having a convex shape facing upward as described above is formed in the concave portion 216 on the surface of the hole 236 and the concave portion 216 facing each other. On the other hand, in the hole 236, a concave portion 237 having a concave shape corresponding to the convex portion 218 is formed. Thereby, it is possible to prevent displacement of the hanging portion 216 after caulking the hole portion 236, and it is possible to further increase the bonding strength of the additional member 210 and the base member 230. In the above-described configuration, the configuration in which the convex portion is formed in the hanging portion 216 (insertion portion) and the concave portion is formed in the hole portion 236 is illustrated. However, the configuration is not limited thereto, and the configuration may be reversed. It is possible.

  In addition, as shown in FIGS. 4A and 4B, in the present embodiment, in the hanging portion 216, which is the insertion portion, a position corresponding to the edge of the hole 236 to be deformed is provided. An inclined surface 216a that is longer toward the inner side is formed. Thus, when the trailing portion 216 and the convex portion 218 are caulked to the hole 236 as described above, the edge of the hole 236 comes into contact with the inclined surface 216a so that the inclined surface 216a functions as a stopper. I do. Therefore, it is possible to prevent the hanging portion 216 and the protruding portion 218 from coming off from the hole portion 236, and to more firmly couple the additional member 210 and the base member 230.

  In the present embodiment, the configuration in which the line handle 200 is attached to the upper end side of the front plate 112 of the drawer 110 has been exemplified, but the present invention is not limited to this. As shown in FIG. 1, the line handle 200 of the present embodiment can be suitably used for the lower edge of the front plate of the hanging cabinet 100b. In that case, it should be noted that the upper and lower parts are reversed in the above embodiment in terms of the upper and lower expressions.

  As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings, but it goes without saying that the present invention is not limited to such examples. It is clear that those skilled in the art can conceive various changes or modifications within the scope of the claims, and these naturally belong to the technical scope of the present invention. I understand.
