Description

本発明は、扉におけるラッチシャフトの軸受装置に係わり、更に詳しくは扉のコーナー部と取付けて縁部の変形を防止する扉におけるラッチシャフトの軸受装置に関するものである。   The present invention relates to a bearing device for a latch shaft in a door, and more particularly to a bearing device for a latch shaft in a door which is attached to a corner portion of the door to prevent deformation of an edge portion.

従来から、キャビネット筐体の前面開口部に開閉扉を回動開閉可能に取付け、該扉の遊端側の上下部背面に筐体の上下框部の係合孔に係脱するラッチを設け、該ラッチを扉の表面側に設けた引手の回動に対して扉の背面側に回転可能に設けたシャフトで連動させる構造のキャビネットは各種提供されている。   Conventionally, an opening / closing door is attached to the front opening of the cabinet housing so as to be able to open and close, and a latch is provided on the upper and lower back surfaces of the free end side of the door to be engaged with and disengaged from the engagement holes of the upper and lower flanges of the housing. Various cabinets having a structure in which the latch is interlocked by a shaft provided rotatably on the back side of the door with respect to the rotation of a pulling handle provided on the front side of the door are provided.

ここで、前記扉の構造として、表面板の周囲を背面側に折曲して縁板を形成するとともに、縁板の後縁を直角に折曲して補強板を形成し、更に補強板の内縁を表面板に向かって折曲して折曲板を形成した構造のものが一般的である。扉の遊端側の上下端部の背面に両端に設けた軸受部材に、ラッチを回転不能に嵌挿したシャフトの両端部を回転可能に支持していた。軸受部材としては、表面板の背面に金属製の軸受金具をスポット溶接した構造のものもあるが、組み立て施工性の向上を図るために、合成樹脂製の軸受部材を前記扉の上下縁部構造を利用して嵌着するものも提供されている。   Here, as the structure of the door, the periphery of the surface plate is bent to the back side to form an edge plate, the rear edge of the edge plate is bent at a right angle to form a reinforcing plate, and the reinforcing plate Generally, the inner edge is bent toward the surface plate to form a bent plate. Both end portions of the shaft, in which the latches are non-rotatably inserted, are rotatably supported by bearing members provided at both ends on the back of the upper and lower end portions on the free end side of the door. Some bearing members have a structure in which metal bearing fittings are spot-welded to the back of the surface plate. However, in order to improve assembly workability, the synthetic resin bearing member is used for the upper and lower edge structure of the door. There is also an item that can be fitted using.

特許文献１には、合成樹脂製のラッチ軸受部材の内部にラッチ部材の基部を回動可能に保持し、該ラッチ部材の基部には角棒からなるシャフトの端部を嵌挿し、該ラッチ軸受部材を、扉の上下縁部に表面板に向けて形成した切起し片に係合させて取付ける構造が記載されている。また、特許文献２には、ラッチ受け具の内部にラッチの基部を回動可能に保持するとともに、シャフトの端部に嵌挿したカムを内部に回転可能に保持し、前記カムとラッチの基部を連動板で連動させた構造であるが、扉の上下縁部の補強板に形成した係合孔にラッチ受け具に形成した係止凸部を係止して取付ける構造が記載されている。   In Patent Document 1, a base portion of a latch member is rotatably held inside a latch bearing member made of synthetic resin, and an end portion of a shaft made of a square bar is fitted into the base portion of the latch member. A structure is described in which a member is attached to the upper and lower edges of the door by engaging with a cut and raised piece formed toward the surface plate. In Patent Document 2, the base of the latch is rotatably held inside the latch receiver, and the cam fitted to the end of the shaft is rotatably held inside. However, there is described a structure in which the locking projections formed on the latch holders are locked and attached to the engagement holes formed on the reinforcing plates at the upper and lower edges of the door.

つまり、従来は扉の上下縁部を利用して軸受部材を取付けるものであるが、前記扉の上下のラッチが筐体の上下框部の係合孔に係合した状態、つまり扉を閉じた状態で地震によって筐体が左右に変形すると、ラッチは筐体の框部の変位に追従して上下に変位するが、その変位の方向は剛性が高い扉が面内方向なので、扉の上下縁部に過大な応力が作用して該縁部が変形し、ラッチ軸受部材が外れて扉が開いてしまうといった問題があった。また、扉が開かないまでも、扉の上下縁部が変形することは、スムーズな扉の開閉に支障を来たすことを意味する。   That is, conventionally, the bearing member is attached using the upper and lower edge portions of the door, but the upper and lower latches of the door are engaged with the engagement holes of the upper and lower flange portions of the housing, that is, the door is closed. If the housing is deformed to the left or right due to an earthquake in the state, the latch will move up and down following the displacement of the buttocks of the housing, but the direction of the displacement is the in-plane direction of the door with high rigidity, so the upper and lower edges of the door Excessive stress is applied to the part, the edge part is deformed, and the latch bearing member is detached to open the door. Moreover, even if the door does not open, deformation of the upper and lower edges of the door means that the door can be smoothly opened and closed.
