Description

本発明は、回転可能な電気及び電子筐体の回転を拘束したり拘束を解除したりすることができるロック機構に関するものであり、筐体の大きさにかかわらず、回転の拘束及び拘束の解除が安全且つスムーズにでき、しかも少スペースで確実に作動するロック機構が要求される。また、モータやエアなどの動力を持たない筐体では、機構構造だけでロック機構を達成したり、ロックの解除を手動で簡単に行うことができたりする必要がある。   The present invention relates to a lock mechanism capable of restraining or releasing the rotation of a rotatable electric and electronic casing, and regardless of the size of the casing, the restraint of the rotation and the release of the restraint. Therefore, there is a demand for a lock mechanism that can be operated safely and smoothly and that operates reliably in a small space. In addition, in a housing that does not have power such as a motor or air, it is necessary to achieve a lock mechanism only with a mechanism structure or to easily release the lock manually.

図3(a)及び(b)に基づいて、従来の筐体の回転ロック機構を説明する。
回転可能な筐体10と固定部材12とが蝶番14で連結されており、筐体10側の蝶番14の取付面14aには、これと直交する方向に突出する突出部材50が取付けられている。突出部材50の先端には、ロックピン52が上方に突出しており、固定部材12にはロックステー54の一端が揺動自在に吊り下げられている。ロックステー54の他端には、ロックピン52を嵌合可能な穴54aが形成されており、突出部材50、ロックピン52及びロックステー54によりロック機構56が構成される。
Based on FIGS. 3A and 3B, a conventional rotation lock mechanism of the housing will be described.
The rotatable housing 10 and the fixing member 12 are connected by a hinge 14, and a projecting member 50 projecting in a direction orthogonal to the mounting surface 14 a of the hinge 14 on the housing 10 side is attached. . A lock pin 52 protrudes upward from the tip of the protruding member 50, and one end of a lock stay 54 is swingably suspended from the fixed member 12. A hole 54 a into which the lock pin 52 can be fitted is formed at the other end of the lock stay 54, and the lock member 56 is configured by the protruding member 50, the lock pin 52, and the lock stay 54.

従来のロック機構56の動作について説明する。
ロック機構56がロックされている状態は、図3(a)に示すように、ロックピン52がロックステー54の穴54aに嵌合され、これにより、筐体10の回転が拘束される。
The operation of the conventional lock mechanism 56 will be described.
In a state where the lock mechanism 56 is locked, as shown in FIG. 3A, the lock pin 52 is fitted into the hole 54a of the lock stay 54, and thereby the rotation of the housing 10 is restricted.

ロックを解除する場合、ロックステー54を手で上方に持上げ、図3(b)に示すように、穴54aからロックピン52を取外すことにより行われる。これにより、筐体10は回転可能な状態になる。   To release the lock, the lock stay 54 is lifted upward by hand, and the lock pin 52 is removed from the hole 54a as shown in FIG. Thereby, the housing | casing 10 will be in the state which can rotate.

次に、ロックする場合、ロックステー54を手で上方に持上げ、図3(a)に示すように、穴54aにロックピン52を嵌合することにより行われ、これにより、筐体10の回転が拘束される。   Next, when locking, the lock stay 54 is lifted upward by hand, and the lock pin 52 is fitted into the hole 54a as shown in FIG. Is restrained.

このように、従来のロック機構56の場合、ロックするときに人の手に頼らなければならないため、万が一ロックを忘れた場合、筐体が簡単に回転してしまい、人や物が筐体にぶつかっただけでも回転してしまうことになる。このため、筐体に挟まれるという人身事故や、筐体が構造物にぶつかるという事故に繋がる可能性がある。   As described above, in the case of the conventional lock mechanism 56, since it is necessary to rely on a person's hand when locking, in the unlikely event that the lock is forgotten, the case is easily rotated, and people and objects are placed in the case. Just hitting it will rotate. For this reason, there is a possibility that it may lead to an accident that a person is caught in the case or an accident that the case hits a structure.

解決しようとする課題は、回転可能な筐体の回転を拘束する際に、自動でロック機構のロックがかからず、また、簡単に手動でロックを解除することができないという点である。   The problem to be solved is that when the rotation of the rotatable housing is constrained, the lock mechanism is not automatically locked, and the lock cannot be easily released manually.

本発明は、筐体を回転させるだけでロック機構のロックが自動で行われることを特徴とする。   The present invention is characterized in that the lock mechanism is automatically locked only by rotating the casing.

すなわち、請求項1記載の発明は、互いに回転可能に連結された2部材間の回転を拘束したり拘束を解除したりすることが可能な回転ロック機構において、
前記一方の部材面には、取付面に対して水平方向に揺動自在に可動部材の一端を連結し、他方の部材面には、可動部材の他端が水平方向及び垂直方向に移動可能に嵌合する嵌合部を設け、該嵌合部は、可動部材の他端の水平方向の揺動は規制するが垂直方向は移動可能に係止する係止部と、一方の部材が回転することによる可動部材の揺動運動を直線運動に変換し可動部材の他端の移動を案内する水平部と、を有することを特徴とする。

A fitting portion for fitting is provided, and the fitting portion restricts the swing of the other end of the movable member in the horizontal direction but is locked so as to be movable in the vertical direction, and one member rotates. And a horizontal portion that converts the swinging motion of the movable member into a linear motion and guides the movement of the other end of the movable member.

また、請求項2記載の発明は、請求項1記載の発明において、前記可動部材は、前記一方の部材面に固定される取付具に連結ピンを介して水平方向に揺動自在に連結されたロッドと、ロッド先端に水平方向には揺動自在に垂直方向には移動自在に連結されるロック部材と、ロック部材に設けられ前記嵌合部に嵌合する嵌合ピンと、により構成されることを特徴とする。   According to a second aspect of the invention, in the first aspect of the invention, the movable member is connected to a fixture fixed to the one member surface so as to be swingable in a horizontal direction via a connecting pin. The rod comprises a rod, a lock member that is swingably movable in the horizontal direction and movable in the vertical direction, and a fitting pin that is provided on the lock member and engages with the fitting portion.

また、請求項3記載の発明は、請求項1又は2記載の発明において、前記嵌合部は、前記他方の部材に取付けられた連結具に形成された開口部であり、該開口部に前記嵌合ピンが取外し不可能に嵌合されることを特徴とする。   The invention according to claim 3 is the invention according to claim 1 or 2, wherein the fitting portion is an opening formed in a connector attached to the other member. The fitting pin is fitted so as not to be removable.

本発明によれば、筐体をロックが必要とされる角度だけ回転させると、嵌合ピンが開口部を移動して係止部に係合し、自動的にロックが掛かるため、ロック忘れを防止することができる。
また、ロックの解除は、手動でロック部材を垂直方向に移動させるだけで嵌合ピンを係止部から、嵌合ピンの水平方向の移動が自由になる水平部に移動させることができるため、ロックの解除を容易に行うことができる。
According to the present invention, when the housing is rotated by an angle that requires locking, the fitting pin moves through the opening and engages with the locking portion, and the lock is automatically applied. Can be prevented.
In addition, unlocking can be performed by moving the fitting pin from the locking portion to the horizontal portion where the movement of the fitting pin in the horizontal direction is free by simply moving the lock member in the vertical direction manually. The lock can be easily released.

FIG. 2A is a detailed view showing a state in which the rotation lock mechanism is locked, and FIG. 2B is a detailed view showing a state in which the lock of the rotation lock mechanism is released.

回転可能な筐体10(一方の部材)と固定部材12(他方の部材)とが蝶番14で連結されており、筐体10側の蝶番14の取付面14a及び固定部材12側の蝶番14の取付面14bに回転ロック機構16が取付けられる。   A rotatable housing 10 (one member) and a fixing member 12 (the other member) are connected by a hinge 14, and the mounting surface 14 a of the hinge 14 on the housing 10 side and the hinge 14 on the fixing member 12 side are connected. The rotation lock mechanism 16 is attached to the attachment surface 14b.

図2に示すように、ロック機構16は、取付面14aに取付具18が固定され、取付具18に連結ピン20を介してロッド22(可動部材)が連結される。ロッド22は、連結ピン20を回転中心として回転自在、すなわち水平方向に揺動自在である。ロッド22の先端には長軸ピン24を介してロック部材26が連結され、ロック部材26は、長軸ピン24を回転中心として回転自在であるとともに、長軸ピン24とともにロッド22の上下方向に移動自在である。ロック部材26には、嵌合ピン28が設けられる。   As shown in FIG. 2, in the lock mechanism 16, a fixture 18 is fixed to the mounting surface 14 a, and a rod 22 (movable member) is connected to the fixture 18 via a connecting pin 20. The rod 22 is rotatable about the connecting pin 20 as a center of rotation, that is, swingable in the horizontal direction. A lock member 26 is connected to the tip of the rod 22 through a long axis pin 24, and the lock member 26 is rotatable about the long axis pin 24 as a center of rotation. It is movable. The lock member 26 is provided with a fitting pin 28.

取付面14bには、連結具30が固定されており、連結具30には、嵌合ピン28が取外し不可能に嵌合され、嵌合ピン28の移動を案内するガイド開口部32(嵌合部)が開口している。ガイド開口部32は、垂直方向に開口する係止部32aと係止部32aの上端から水平方向に開口する水平部32bとにより構成され、係止部32aは嵌合ピン28の水平方向の移動は拘束するが垂直方向の移動を可能とする。また、係止部32aには、嵌合ピン28が係合し、嵌合ピン28が容易に上方へ移動することを規制する引っ掛り部32cが形成されている。   A coupling tool 30 is fixed to the mounting surface 14b, and a fitting pin 28 is detachably fitted to the coupling tool 30, and a guide opening 32 (fitting) that guides the movement of the fitting pin 28. Part) is open. The guide opening 32 includes a locking portion 32a that opens in the vertical direction and a horizontal portion 32b that opens in the horizontal direction from the upper end of the locking portion 32a. The locking portion 32a moves in the horizontal direction of the fitting pin 28. Restrains but allows vertical movement. The engaging portion 32a is formed with a hook portion 32c that engages with the fitting pin 28 and restricts the fitting pin 28 from easily moving upward.

水平部32bは、嵌合ピン28の水平方向の移動を可能とするものであり、ロック部材26が長軸24を回転中心としてロッド22に対して回転自在であるため、ロッド22の揺動運動によるロッド22と水平部32bとの角度変化をロック部材26が吸収し、ロッド22の揺動運動が、嵌合ピン28の水平方向の直線運動に変換され、嵌合ピン28が水平部32bを移動する。   The horizontal portion 32b enables the fitting pin 28 to move in the horizontal direction, and the lock member 26 is rotatable with respect to the rod 22 about the long axis 24. The lock member 26 absorbs the change in the angle between the rod 22 and the horizontal portion 32b due to the movement, and the swinging motion of the rod 22 is converted into the horizontal linear motion of the fitting pin 28. The fitting pin 28 moves the horizontal portion 32b. Moving.

次に、実施例1の動作について説明する。図1(a)及び図2(a)に示すように、回転ロック機構16がロックされているときは、嵌合ピン26が係止部32aにあり、引っ掛り部32cに係合しており、不意の筐体回転時でも、引っ掛り部32cから外れて水平部32bに移動することなく、確実にロックされている。   Next, the operation of the first embodiment will be described. As shown in FIGS. 1A and 2A, when the rotation lock mechanism 16 is locked, the fitting pin 26 is in the locking portion 32a and is engaged with the catching portion 32c. Even when the casing is unexpectedly rotated, it is securely locked without moving from the hook portion 32c to the horizontal portion 32b.

次に、ロックを解除する場合は、ロック部材26を上方に押し上げる。すると、ロック部材26とともに長軸ピン24が上方に移動し、嵌合ピンと引っ掛り部32cの係合が外れて、嵌合ピン28が係止部32aを上昇し水平部32bに移動し、ロックが解除されて、筐体10は回転自在な状態となる。   Next, when releasing the lock, the lock member 26 is pushed upward. Then, the long pin 24 is moved upward together with the lock member 26, the engagement between the fitting pin and the hook portion 32c is released, and the fitting pin 28 moves up the locking portion 32a and moves to the horizontal portion 32b. Is released, and the housing 10 becomes rotatable.

次に、筐体10を固定部材12方向に回転させると、ロッド22が揺動し、嵌合ピン28が水平部32bの図2中右方向へ移動していく。筐体10が図1(b)のように固定部材12と重なった状態及び回転ロック機構16が図2(b)のように嵌合ピン28が水平部32bの右端部まで移動した状態になるまで筐体10は回転することができる。   Next, when the housing 10 is rotated in the direction of the fixing member 12, the rod 22 swings and the fitting pin 28 moves to the right in FIG. 2 of the horizontal portion 32b. The housing 10 overlaps with the fixing member 12 as shown in FIG. 1B, and the rotation lock mechanism 16 moves to the right end of the horizontal portion 32b as shown in FIG. 2B. The housing 10 can rotate up to.

次に、図1(a)に示す状態に筐体10を戻す場合、筐体10を回転させると、ロッド22が揺動し、嵌合ピン28が水平部32bを左方向に移動する。筐体10がロックを必要とする角度に達すると、嵌合ピン28が係止部32aの位置まで移動するため係止部32aを自由落下し、引っ掛り部32cに係合して回転ロック機構16がロックされ、筐体10の回転が拘束される。   Next, when returning the housing 10 to the state shown in FIG. 1A, when the housing 10 is rotated, the rod 22 swings and the fitting pin 28 moves the horizontal portion 32b to the left. When the housing 10 reaches an angle that requires locking, the fitting pin 28 moves to the position of the locking portion 32a, so that the locking portion 32a freely falls and engages with the hooking portion 32c to rotate. 16 is locked and the rotation of the housing 10 is restrained.
