Lock section structure
A storage device 1 has a storage device body 2 and an opening and closing member 4 , which are supported to be capable of pivoting about the center of opening and closing movement, the center being provided on one side. A lock mechanism 13 is provided on the other side of both the storage device body 2 and an opening 3 . The lock mechanism 13 is provided with a lock member 16 , an unlocking button 17 , a cam mechanism 18 , and a biasing member 19 . The lock member 16 is a pivotable member 22 capable of pivoting about a lock pivot shaft 21 . The opening and closing member 4 has a pressure receiving portion 52 on the inner surface side thereof, and the pressure receiving portion 52 is pushed out in an opening direction 23 by the lock member 16 which is caused to pivot in an unlocking direction.
1. A lock section structure, comprising:
a storage device comprising a storage device body and an opening and closing member adapted to open or close an opening with which the storage device body is formed, the storage device body and the opening and closing member being supported to be capable of pivoting about an opening/closing center axis portion disposed on one side that is either a lower side or an upper side, or either a left side or a right side, of both the storage device body and the opening and closing member; and
a lock mechanism for allowing locking and unlocking, provided on another side that is a side opposite to the one side;
wherein the lock mechanism comprises
a lock member having an engaging surface, at which the lock member is structured to engage with or disengage from an accepting portion provided to the opening and closing member,
an unlocking button capable of being pushed against the storage device body,
a cam mechanism adapted to disengage the lock member from the accepting portion by a push of the unlocking button, and
a biasing member for constantly biasing the lock member toward a locking direction,
wherein the lock member is structured as a pivotable member pivotable about a lock pivot shaft,
wherein the engaging surface of the lock member and the accepting portion of the opening and closing member form a plane perpendicular to an opening direction that is a direction toward which the opening and closing member starts to open from a closed state about the opening/closing center axis portion,
wherein the opening and closing member forms a surface extending generally in a vertical direction and a horizontal direction,
wherein the opening and closing member is arranged to downwardly pivot about the opening/closing center axis portion disposed on the lower side of both the storage device body and the opening and closing member,
wherein the opening and closing member is arranged to be locked at an upper side of the opening and closing member by the lock mechanism,
wherein the opening/closing center axis portion is located on a backward side in the storage device body, to which an opening direction that is a direction toward which the opening and closing member starts to open from the closed state about the opening/closing center axis portion is directed forwardly and downwardly,
wherein a pushing direction of the unlocking button is backwardly and downwardly,
wherein the lock mechanism further comprises a holder member attachable to the storage device body,
wherein the holder member allows the lock pivot shaft to be pivotally supported,
wherein a cam follower comprising the cam mechanism is disposed on the lock member at a location forward from a part pivotally supported by the lock pivot shaft,
wherein the unlocking button has, at a backward position of the unlocking button, a cam plate extending in the pushing direction,
wherein the cam plate is formed with a cam surface including a surface inclined backwardly and downwardly, and being configured to guide the cam follower with respect to the cam plate to rotationally move the lock member toward an unlocking direction, and
wherein the biasing member is provided to be interposed between the storage device body or the holder member and the lock member.
2. A lock section structure as claimed in claim 1 , wherein:
the lock member is provided to include, at a backward part of the lock member, a bearing section extending in the pushing direction to support the lock pivot shaft,
the lock member is further provided with, at a forward part of the lock member, a locking arm section extending toward the accepting portion while having the engaging surface at an end portion, thereby having a bent shape in a side view, and
the lock member, which has the bent shape in the side view, has a bending section between the bearing section and the locking arm section, at which the cam follower is provided.
3. A lock section structure as claimed in claim 1 , wherein the unlocking button, the cam follower and the lock pivot shaft are arranged in series along the pushing direction.
