Description

本発明は、板材を平板状に連結し又は角度を成す状態で連結するための板材連結機構に関する。   The present invention relates to a plate connecting mechanism for connecting plate members in a plate shape or in an angled state.

従来、このような板材連結機構として、各板材の連結される側の端面に固定され、該端面に沿って延びた連結機構が固定されたものが知られている（例えば、特許文献１参照）。この特許文献１の連結機構は、上記端面に沿って延び、該端面に平行な２つの当接面を有する。これらの当接面は、相互に段差面を介して接続され、段差を形成している。   Conventionally, as such a plate member connecting mechanism, a plate member is known which is fixed to an end face on a side to be connected of each plate member and is fixed to a connecting mechanism extending along the end face (for example, see Patent Document 1). . The connecting mechanism disclosed in Patent Document 1 has two contact surfaces extending along the end surface and parallel to the end surface. These contact surfaces are connected to each other via a step surface to form a step.

各板材同士を平板状に連結する場合には、両板材の連結機構の当接面及び段差面が当接され、結合される。この結合は、当接する当接面の一方及び他方に設けられた凹条と凸条を嵌合させるとともに、両段差面の凹条により形成される挿入孔に棒状の部材を挿入することにより行われる。   When connecting the plate members to each other in a flat plate shape, the contact surface and the step surface of the connecting mechanism of the two plate members are brought into contact with each other and connected. This connection is performed by fitting the concave and convex ridges provided on one and the other of the abutting surfaces, and inserting a rod-shaped member into an insertion hole formed by the concave ridges on both stepped surfaces. Will be

また、各板材同士を直角を成すように連結する場合には、両板材の連結機構の一方の当接面が他方の段差面に当接するように両連結機構を組み合わせ、同様に凹条と凸条とを嵌合させ、及び挿入孔へ棒状部材を挿入することにより連結が行われる。   Further, when connecting the respective plate members so as to form a right angle, the two connecting mechanisms are combined such that one contact surface of the connecting mechanism of the two plate members abuts on the other step surface, and similarly, the concave and convex portions are formed. The connection is performed by fitting the strip and inserting the rod-shaped member into the insertion hole.

しかしながら、上記特許文献１の板材連結機構によれば、連結する板材の大きさや数、用途などによっては、平板状に連結される板材の連結部分の強度を高めることや、直角に連結する場合の角部の強度を高めることが望ましい場合がある。   However, according to the plate connecting mechanism of Patent Document 1, depending on the size and the number of the connecting plate, the use, and the like, the strength of the connecting portion of the plate connected in a flat plate shape is increased, or the connecting is performed at a right angle. It may be desirable to increase the strength of the corners.

The two second contact surfaces of the second connecting portion are adjacent to each other, and the second surfaces of the first and second plate material fixing portions are connected to the first and second plate materials by the second connecting portion. The fixing portions are configured to be adjacent to each other when they are combined .

本発明において、板材連結機構により第１、第２板材を平板状に連結する場合には、まず、第１、第２板材に第１、第２板材固定部が固定される。そして、第１、第２板材固定部が第１連結部に結合される。   In the present invention, when connecting the first and second plate members in a plate shape by the plate member connection mechanism, first, the first and second plate member fixing portions are fixed to the first and second plate members. Then, the first and second plate material fixing portions are coupled to the first connecting portion.

この結合に際しては、まず、第１、第２板材固定部の第１〜第３面が、第１、第２連結部の第１〜第３接面に当接される。このとき、第３面と第３接面の凹条により挿入孔が形成される。また、第１、第２面、第１、第２接面において凸条が凹条に嵌合する。次に、形成された挿入孔に挿入部材が挿入される。これにより、第１、第２板材の連結が完了する。   In this connection, first, the first to third surfaces of the first and second plate material fixing portions are brought into contact with the first to third contact surfaces of the first and second connecting portions. At this time, an insertion hole is formed by the concave stripe between the third surface and the third contact surface. Also, the ridges fit into the ridges on the first and second surfaces, and the first and second contact surfaces. Next, the insertion member is inserted into the formed insertion hole. Thus, the connection of the first and second plate members is completed.

板材連結機構により第１、第２板材を角度を成す状態で連結する場合には、まず、第１、第２板材に第１、第２板材固定部が固定される。そして、第１、第２板材固定部が第２連結部に結合される。この結合は、上述の第１連結部の場合と同様にして行われ、これにより第１、第２板材の連結が完了する。   When connecting the first and second plate members at an angle by the plate member connection mechanism, first, the first and second plate member fixing portions are fixed to the first and second plate members. Then, the first and second plate fixing portions are coupled to the second connecting portion. This connection is performed in the same manner as in the case of the above-described first connection portion, whereby the connection between the first and second plate members is completed.

これによれば、第１、第２板材の連結部分に、それぞれ第１、第２連結部が介在し、これらが支柱としての役割を果たす。すなわち、第１連結部は、その両側の第１板材及び第２板材を強固に支持することができる。また、第２連結部は、両側の第１部材及び第２部材のコーナー部に位置してこれを強固に支持して保護することができる。   According to this, the first and second connecting portions are interposed at the connecting portions of the first and second plate members, respectively, and these serve as pillars. That is, the first connecting portion can firmly support the first and second plate members on both sides thereof. In addition, the second connecting portion is located at the corners of the first member and the second member on both sides, and can firmly support and protect it.

また、その際に、第１、第２板材固定部と第１、第２連結部とは、段差状に噛み合って結合するので、その結合は強固に行われる。また、第１、第２板材固定部は、第１、第２連結機構で共用されるので、これらを連結する第１連結部又は第２連結部を選択するだけで、第１、第２板材を平板状又は角度を成す状態のいずれの態様においても連結することができる。   Also, at this time, the first and second plate material fixing portions and the first and second connecting portions are engaged with each other in a step-like manner, so that the connection is firmly performed. Further, since the first and second plate fixing portions are shared by the first and second connection mechanisms, the first and second plate members can be selected simply by selecting the first connection portion or the second connection portion for connecting these. Can be connected in any form of a flat plate or an angle.

また、第１板材と第２板材とが成す狭角側から見て、第２連結部が、第１、第２板材固定部により隠された状態となるので、該狭角側から見た第１、第２板材の連結部の見た目を良好なものにすることができる。 Further , since the second connecting portion is hidden by the first and second plate material fixing portions when viewed from the narrow angle side formed by the first plate material and the second plate material, the second connecting portion is hidden by the narrow angle side. (1) The appearance of the connecting portion of the second plate can be improved.

また、前記第２連結部の２つの前記第２接面は相互に隣接しており、前記第１、第２板材固定部の各第２面は、該第２連結部に該第１、第２板材固定部が結合したときに相互に隣接するように構成されているので、第１板材と第２板材とが成す狭角側から見て、第２連結部を、第１、第２板材固定部により確実に隠された状態とすることができる。 Also, two of the second contact surface of the second connecting portion are adjacent to each other, the first, the second face of the second plate fixing unit, the first to the second connecting portion, the Since the two plate material fixing portions are configured to be adjacent to each other when they are combined , the second connecting portion is formed by the first and second plate materials when viewed from the narrow angle side formed by the first plate material and the second plate material. The state can be reliably hidden by the fixing portion.
