特開２００３−０６１８００号公報JP 2003-061800 A

しかしながら、上記従来の広告枠では、複数の枠部材をロウ付けにより接合するため、ロウ付けを行うための高い技術（熟練者によるロウ付け作業）を要するとともに、高い技術が必要な分、接合不良が生じやすく歩留まりが低下するという不都合がある。また、ロウ付けは、熟練者によるロウ付け作業が必要であるため、自動化を行いにくいという不都合がある。その結果、複数の枠部材を容易に接合させるのが困難であるとともに、歩留まりを向上させて効率よく広告枠を製造することが困難であり、接合工程の自動化も図りにくいという問題点がある。 However, in the above-described conventional advertising frame, since a plurality of frame members are joined by brazing, a high technique for brazing (brazing work by a skilled person) is required, and poor joining is required because the high technique is required. This is disadvantageous in that the yield tends to occur and the yield decreases. In addition, since brazing requires a brazing operation by a skilled person, there is an inconvenience that automation is difficult to perform. As a result, it is difficult to easily join the plurality of frame members, it is difficult to efficiently manufacture the advertising frame by improving the yield, and it is difficult to automate the joining process.

この発明は、上記のような課題を解決するためになされたものであり、この発明の１つの目的は、複数の枠部材を容易に接合させることにより、歩留まりを向上させて効率よく広告枠を製造することが可能で、かつ、自動化も図りやすい広告枠および広告枠の製造方法を提供することである。 The present invention has been made to solve the above-described problems, and one object of the present invention is to improve the yield by efficiently joining a plurality of frame members, thereby efficiently forming an advertisement frame. An object of the present invention is to provide an advertising space which can be manufactured and which can be easily automated, and a method for manufacturing the advertising space.

上記目的を達成するために、この発明の第１の局面による広告枠は、互いに接合されることにより枠状に形成された複数の枠部材を備え、枠部材の各々は、前枠部と、後枠部と、前枠部および後枠部の外周側を接続する接続部と、を含み、複数の枠部材が互いに接合される部分には、後枠部に設けられた開口と、開口を介して前枠部同士が後枠部側から溶接または固相接合により接合された第１接合部と、が設けられている。 In order to achieve the above object, an advertising frame according to a first aspect of the present invention includes a plurality of frame members formed into a frame shape by being joined to each other, and each of the frame members includes a front frame portion, A rear frame portion, a connection portion for connecting the outer peripheral side of the front frame portion and the rear frame portion, and a portion where a plurality of frame members are joined to each other, an opening provided in the rear frame portion, an opening And a first joint portion in which the front frame portions are joined to each other from the rear frame portion side by welding or solid-phase joining.

上記第１の局面による広告枠では、上記のように、開口を介して前枠部同士が後枠部側から溶接または固相接合により接合された第１接合部を設ける。これにより、ロウ付けに比べて高い技術を必要としない溶接または固相接合により複数の枠部材を互いに接合することができるので、複数の枠部材を容易に接合させることにより、歩留まりを向上させて効率よく広告枠を製造することができ、かつ、自動化も図りやすくすることができる。また、前枠部を後側から開口を介して溶接または固相接合により接合することができるので、前側から接合する場合と異なり、接合部に変色や凹凸が生じたとしても、広告枠の前面に変色や凹凸が生じるのを抑制することができる。 In the advertising frame according to the first aspect, as described above, the first joint portion in which the front frame portions are joined to each other from the rear frame portion side through the opening by welding or solid-phase joining is provided. Thereby, since a plurality of frame members can be joined to each other by welding or solid-phase joining that does not require a high technique as compared with brazing, the yield can be improved by easily joining the plurality of frame members. Advertising frames can be efficiently manufactured, and automation can be easily achieved. Also, since the front frame part can be joined by welding or solid phase joining from the rear side through the opening, unlike the case of joining from the front side, even if discoloration or unevenness occurs at the joint part, the front of the advertising frame Discoloration and unevenness can be suppressed.

上記第１の局面による広告枠において、好ましくは、後枠部の開口は、前後方向に見て、前枠部に覆われるように設けられている。このように構成すれば、後枠部に設けられた開口を前方に露出しないように前枠部により覆うことができる。 In the advertisement frame according to the first aspect, preferably, the opening of the rear frame portion is provided so as to be covered by the front frame portion when viewed in the front-rear direction. With this configuration, the opening provided in the rear frame portion can be covered by the front frame portion so as not to be exposed forward.

The portion to be joined is provided with a second joint portion in which the rear frame portions are joined to each other from behind by welding or solid-state joining at a position adjacent to the opening of the rear frame portion. With this configuration, the rear frame portion can be joined from the rear side by welding or solid-phase joining similarly to the front frame portion, so that the joining operation can be performed from the same rear direction. Thus, the joining operation can be performed easily and efficiently, and automation can be easily achieved. Further, unlike the case where the rear frame portion is joined from the front side, even if discoloration or unevenness occurs in the joint portion, it is possible to suppress the discoloration or unevenness from occurring on the front surface of the advertising frame.

上記複数の枠部材が互いに接合される部分に第２接合部が設けられている構成において、好ましくは、枠部材の各々は、前後方向に見て、枠部材が延びる方向と傾斜する傾斜辺を含み、複数の枠部材は、傾斜辺同士が互いに接合されており、第１接合部および第２接合部は、傾斜辺に沿って直線状に配列されている。このように構成すれば、傾斜辺に沿って直線状に配置された第１接合部および第２接合部の接合により、複数の枠部材を隙間なく確実に接続することができる。また、接合作業の作業効率を向上させることができる。 In the configuration in which the second joining portion is provided at a portion where the plurality of frame members are joined to each other, preferably, each of the frame members has an inclined side that is inclined with the direction in which the frame member extends, when viewed in the front-back direction. The plurality of frame members include inclined sides joined to each other, and the first joint and the second joint are arranged linearly along the inclined sides. According to this structure, the plurality of frame members can be reliably connected without gaps by joining the first joint and the second joint arranged linearly along the inclined side.

With this configuration, the opening area can be made relatively large, so that the work on the first joining portion that joins the front frame portion can be easily performed through the opening.

上記第１の局面による広告枠において、好ましくは、後枠部の開口は、互いに接続される枠部材の一方には、枠形状に沿った方向において第１長さを有するように形成され、互いに接続される枠部材の他方には、枠形状に沿った方向において第１長さよりも小さい第２長さを有するように形成されている。このように構成すれば、比較的大きい第１長さを有する開口の方向から接合作業のためのツール（たとえば、溶接を行うための溶接棒）を差し入れることができるので、接合作業を容易に行うことができる。 In the advertising frame according to the first aspect, preferably, the opening of the rear frame portion is formed on one of the frame members connected to each other so as to have a first length in a direction along the frame shape. The other of the connected frame members is formed to have a second length smaller than the first length in a direction along the frame shape. According to this structure, a joining tool (for example, a welding rod for performing welding) can be inserted from the direction of the opening having the relatively large first length, so that the joining operation can be easily performed. It can be carried out.

この場合、好ましくは、後枠部の開口は、互いに接続される枠部材の一方には、枠形状に沿った方向における長さが第１長さの長孔形状を有するように設けられ、互いに接続される枠部材の他方には、枠形状に沿った方向における長さが第２長さの略三角形状を有するように設けられている。このように構成すれば、開口の大きさを過度に大きくすることなく、接合作業を容易に行うことができる。 In this case, preferably, the opening of the rear frame portion is provided on one of the frame members connected to each other such that the length in a direction along the frame shape has a first-hole-shaped long hole shape. The other of the connected frame members is provided such that the length in a direction along the frame shape has a substantially triangular shape having a second length. With this configuration, the joining operation can be easily performed without excessively increasing the size of the opening.

上記第１の局面による広告枠において、好ましくは、複数の枠部材の少なくとも１つには、広告媒体を挿入するための挿入口が接続部に設けられており、第１接合部は、広告媒体を挿入する方向に見て、挿入口の延びる方向における挿入口の範囲内に配置されているとともに、前枠部から後枠部側方向に突出しないように形成されている。このように構成すれば、挿入口から挿入された広告媒体が第１接合部に干渉するのを抑制することができるので、広告媒体を挿入口から容易に出し入れすることができる。 In the advertisement frame according to the first aspect, preferably, at least one of the plurality of frame members is provided with an insertion port for inserting an advertisement medium in the connection portion, and the first joint portion includes an advertisement medium. When viewed in the direction in which the insertion slot is inserted, it is arranged within the range of the insertion slot in the direction in which the insertion slot extends, and is formed so as not to protrude from the front frame toward the rear frame. According to this structure, it is possible to prevent the advertisement medium inserted from the insertion slot from interfering with the first joining portion, and thus the advertisement medium can be easily taken in and out of the insertion slot.

上記第１の局面による広告枠において、好ましくは、複数の枠部材は、アルミニウム材により形成されている。このように構成すれば、接合部に変色や凹凸が生じやすいアルミニウム材により枠部材を形成したとしても、枠部材同士が後側から接合されるので、広告枠の前面に変色や凹凸が生じるのを抑制することができる。 In the advertisement frame according to the first aspect, preferably, the plurality of frame members are formed of an aluminum material. With this configuration, even when the frame member is formed of an aluminum material that is liable to cause discoloration and unevenness in the joint, the frame members are joined from the rear side, and discoloration and unevenness occur on the front surface of the advertising frame.

（本実施形態の効果）
本実施形態では、以下のような効果を得ることができる。 (Effect of this embodiment)
In the present embodiment, the following effects can be obtained.

本実施形態では、上記のように、開口１５を介して前枠部１１同士が後枠部１２側から溶接または固相接合により接合された第１接合部２１を設ける。これにより、ロウ付けに比べて高い技術を必要としない溶接または固相接合により複数の枠部材１〜４を互いに接合することができるので、複数の枠部材１〜４を容易に接合させることにより、歩留まりを向上させて効率よく広告枠１００を製造することができ、かつ、自動化も図りやすくすることができる。また、前枠部１１を後側（Ｙ２方向側）から開口１５を介して溶接または固相接合により接合することができるので、前側（Ｙ１方向側）から接合する場合と異なり、接合部に変色や凹凸が生じたとしても、広告枠１００の前面に変色や凹凸が生じるのを抑制することができる。 In the present embodiment, as described above, the first joint portion 21 in which the front frame portions 11 are joined to each other from the rear frame portion 12 through the opening 15 by welding or solid-phase joining is provided. Thereby, since the plurality of frame members 1 to 4 can be joined to each other by welding or solid-phase joining that does not require a high technique compared to brazing, the plurality of frame members 1 to 4 can be easily joined. Thus, the advertising space 100 can be efficiently manufactured by improving the yield, and automation can be easily achieved. Further, since the front frame portion 11 can be joined by welding or solid phase joining from the rear side (Y2 direction side) through the opening 15, unlike the case of joining from the front side (Y1 direction side), discoloration occurs at the joining portion. Even if irregularities or irregularities occur, discoloration or irregularities on the front surface of the advertising frame 100 can be suppressed.

また、本実施形態では、上記のように、後枠部１２の開口１５を、前後方向（Ｙ方向）に見て、前枠部１１に覆われるように設ける。これにより、後枠部１２に設けられた開口１５を前方に露出しないように前枠部１１により覆うことができる。 Further, in the present embodiment, as described above, the opening 15 of the rear frame 12 is provided so as to be covered by the front frame 11 when viewed in the front-rear direction (Y direction). Thereby, the opening 15 provided in the rear frame portion 12 can be covered by the front frame portion 11 so as not to be exposed to the front.

また、本実施形態では、上記のように、複数の枠部材１〜４が互いに接合される部分に、後枠部１２の開口１５に隣接する位置において後枠部１２同士が後ろ側（Ｙ２方向側）から溶接または固相接合により接合された第２接合部２２を設ける。これにより、後枠部１２も前枠部１１と同様に後側から溶接または固相接合により接合することができるので、同じ後方向から接合作業を行うことができる。これにより、接合作業を容易かつ効率よく行うことができるとともに、自動化も図りやすくすることができる。また、後枠部１２を前側（Ｙ１方向側）から接合する場合と異なり、接合部に変色や凹凸が生じたとしても、広告枠の前面に変色や凹凸が生じるのを抑制することができる。 Further, in the present embodiment, as described above, the rear frame portions 12 are located on the rear side (in the Y2 direction) at a position adjacent to the opening 15 of the rear frame portion 12 at the portion where the plurality of frame members 1 to 4 are joined to each other. Side), a second joint portion 22 joined by welding or solid-phase joining is provided. Thus, the rear frame portion 12 can be joined by welding or solid-phase joining from the rear side similarly to the front frame portion 11, so that the joining operation can be performed from the same rear direction. Thus, the joining operation can be performed easily and efficiently, and automation can be easily achieved. Further, unlike the case where the rear frame portion 12 is joined from the front side (Y1 direction side), even if discoloration or unevenness occurs in the joint portion, it is possible to suppress the discoloration or unevenness from occurring on the front surface of the advertising frame.

また、本実施形態では、上記のように、第１接合部２１および第２接合部２２を、傾斜辺１６に沿って直線状に配列する。これにより、傾斜辺１６に沿って直線状に配置された第１接合部２１および第２接合部２２の接合により、複数の枠部材１〜４を隙間なく確実に接続することができる。また、接合作業の作業効率を向上させることができる。 In the present embodiment, as described above, the first joint 21 and the second joint 22 are linearly arranged along the inclined side 16. Thereby, by joining the first joint portion 21 and the second joint portion 22 linearly arranged along the inclined side 16, the plurality of frame members 1 to 4 can be reliably connected without gaps. Further, the working efficiency of the joining operation can be improved.

また、本実施形態では、上記のように、第２接合部２２は、傾斜辺１６に沿った方向において、第１接合部２１よりも大きい長さを有している。これにより、第１接合部２１よりも長い第２接合部２２により、前枠部１１よりも大きい幅を有する後枠部１２を確実に接合することができる。 Further, in the present embodiment, as described above, the second joint portion 22 has a longer length than the first joint portion 21 in the direction along the inclined side 16. Thereby, the rear frame part 12 having a larger width than the front frame part 11 can be reliably bonded by the second bonding part 22 longer than the first bonding part 21.

また、本実施形態では、上記のように、後枠部１２の開口１５は、前後方向（Ｙ方向）に見て、第２接合部２２の面積よりも大きい開口面積を有している。これにより、開口面積を比較的大きくすることができるので、前枠部１１を接合する第１接合部２１に対する作業を開口１５を介して容易に行うことができる。 Further, in the present embodiment, as described above, the opening 15 of the rear frame portion 12 has an opening area larger than the area of the second joint portion 22 when viewed in the front-rear direction (Y direction). Thereby, the opening area can be made relatively large, so that the work on the first joining portion 21 for joining the front frame portion 11 can be easily performed through the opening 15.

また、本実施形態では、上記のように、後枠部１２の開口１５は、枠部材２および３には、枠形状に沿った方向（Ｙ方向）において第１長さＬ３を有するように形成され、枠部材１および４には、枠形状に沿った方向（Ｘ方向）において第１長さＬ３よりも小さい第２長さＬ４を有するように形成されている。これにより、比較的大きい第１長さＬ３を有する開口１５の方向から接合作業のためのツールを差し入れることができるので、接合作業を容易に行うことができる。 In the present embodiment, as described above, the opening 15 of the rear frame portion 12 is formed in the frame members 2 and 3 so as to have the first length L3 in a direction (Y direction) along the frame shape. The frame members 1 and 4 are formed so as to have a second length L4 smaller than the first length L3 in a direction (X direction) along the frame shape. Thereby, a tool for the joining operation can be inserted from the direction of the opening 15 having the relatively large first length L3, so that the joining operation can be easily performed.

また、本実施形態では、上記のように、後枠部１２の開口１５は、枠部材２および３には、枠形状に沿った方向（Ｙ方向）における長さが第１長さＬ３の長孔形状を有するように設けられ、枠部材１および４には、枠形状に沿った方向（Ｘ方向）における長さが第２長さＬ４の略三角形状を有するように設けられている。これにより、開口１５の大きさを過度に大きくすることなく、接合作業を容易に行うことができる。 Further, in the present embodiment, as described above, the opening 15 of the rear frame portion 12 has a length in the direction (Y direction) along the frame shape of the frame members 2 and 3 that is equal to the first length L3. The frame members 1 and 4 are provided so as to have a substantially triangular shape having a second length L4 in a direction (X direction) along the frame shape. Accordingly, the joining operation can be easily performed without excessively increasing the size of the opening 15.

また、本実施形態では、上記のように、第１接合部２１は、広告媒体を挿入する方向（Ｚ方向）に見て、挿入口１３ａの延びる方向（Ｘ方向）における挿入口１３ａの範囲内に配置されているとともに、前枠部１１から後枠部１２側方向に突出しないように形成されている。これにより、挿入口１３ａから挿入された広告媒体が第１接合部２１に干渉するのを抑制することができるので、広告媒体を挿入口１３ａから容易に出し入れすることができる。 Further, in the present embodiment, as described above, the first joint portion 21 is within the range of the insertion slot 13a in the direction in which the insertion slot 13a extends (X direction) when viewed in the direction (Z direction) in which the advertising medium is inserted. And is formed so as not to project from the front frame 11 toward the rear frame 12. Thus, the advertisement medium inserted from the insertion slot 13a can be prevented from interfering with the first joint portion 21, so that the advertisement medium can be easily taken in and out of the insertion slot 13a.

また、本実施形態では、上記のように、複数の枠部材１〜４を、アルミニウム材により形成する。これにより、接合部に変色や凹凸が生じやすいアルミニウム材により枠部材１〜４を形成したとしても、枠部材１〜４同士が後側（Ｙ２方向側）から接合されるので、広告枠１００の前面に変色や凹凸が生じるのを抑制することができる。 In the present embodiment, as described above, the plurality of frame members 1 to 4 are formed of an aluminum material. Accordingly, even if the frame members 1 to 4 are formed of an aluminum material that is liable to cause discoloration and unevenness at the joint, the frame members 1 to 4 are joined from the rear side (Y2 direction side). Discoloration and unevenness on the front surface can be suppressed.
