Abstract

An opening and closing mechanism of a double opening storage device including a box main body and a lid body includes a rod and an engagement hole corresponding to a first rotating shaft, a rod and an engagement hole corresponding to a second rotating shaft, first and second biasing members that engage the rods with the engagement holes, first and second operation units that displace the rods in an engagement-releasing direction by an opening operation, and a malfunction prevention device that prevents the opening operation of the first operation unit and the second operation unit from being performed at the same time. The malfunction prevention device includes a base member, first and second stoppers that are respectively rotatable around a first shaft and a second shaft with respect to the base member, and a spring member which is interposed between the first and second stoppers.

First claim

What is claimed is:

1. A double opening storage device comprising:
a box main body including an accommodation unit provided with an opening;
a lid body that covers the opening to be openable and closable; and
an opening and closing mechanism that makes the lid body perform an opening and closing operation around a rotating shaft selected from between a first rotating shaft and a second rotating shaft which respectively extend in a front-rear direction along a peripheral edge of the opening, wherein:
the opening and closing mechanism includes:
a first rod that is disposed in the lid body to correspond to the first rotating shaft and is displaced to be engageable with the box main body side;
a second rod that is disposed in the lid body to correspond to the second rotating shaft and is displaced to be engageable with the box main body side;
a first engagement hole that is provided on the box main body side to correspond to the first rod and is engageable with a tip end of the first rod;
a second engagement hole that is provided on the box main body side to correspond to the second rod and is engageable with a tip end of the second rod;
a first biasing member that generates a biasing force for engaging the first rod with the first engagement hole;
a second biasing member that generates a biasing force for engaging the second rod with the second engagement hole;
a first operation unit that displaces the first rod in a releasing direction in which the engagement with the first engagement hole is released against the biasing force of the first biasing member by an opening operation;
a second operation unit that displaces the second rod in a releasing direction in which the engagement with the second engagement hole is released against the biasing force of the second biasing member by an opening operation; and
a malfunction prevention device that prevents the displacement of the first rod due to the opening operation to the first operation unit and the displacement of the second rod due to the opening operation to the second operation unit from being performed at the same time;

the malfunction prevention device includes:
a base member that is attached to a center portion in a left-right direction of the lid body;
a first stopper that is disposed on a left side with respect to the base member and is rotatable around a first shaft extending in a front-rear direction with respect to the base member;
a second stopper that is disposed on a right side with respect to the base member and is rotatable around a second shaft extending in the front-rear direction with respect to the base member; and
a spring member which includes one end fixed to the first stopper and the other end fixed to the second stopper, and which generates a biasing force for rotating the first stopper in a first rotating direction around the first shaft and for rotating the second stopper in a second rotating direction around the second shaft;

the first stopper includes:
a first rotation restricting unit that restricts rotation of the first stopper in the first rotating direction due to the biasing force of the spring member by abutting against the box main body when the lid body is not in a left open state; and
a first displacement restricting unit that restricts displacement of the first rod in a direction to be engaged with the first engagement hole against the biasing force of the first biasing member by abutting against a tip end surface of the first rod in a state where the first stopper rotates in the first rotating direction due to the biasing force of the spring member when the lid body is in the left open state; and

the second stopper includes:
a second rotation restricting unit that restricts rotation of the second stopper in the second rotating direction against the biasing force of the spring member by abutting against the box main body when the lid body is not in a right open state; and
a second displacement restricting unit that restricts displacement of the second rod in a direction to be engaged with the second engagement hole against the biasing force of the second biasing member by abutting against a tip end surface of the second rod in a state where the second stopper rotates in the second rotating direction due to the biasing force of the spring member when the lid body is in the right open state.

2. The double opening storage device according to claim 1 , wherein
the base member, the first stopper, the second stopper, and the spring member are unitized.

3. The double opening storage device according to claim 1 , wherein:
the malfunction prevention device includes:
a retainer that is rotatably supported around a support shaft in the lid body;
a first pin provided in any one of the first rod and the retainer;
a first pin insertion hole which is provided in the other one of the first rod and the retainer, and into which the first pin is inserted in a state of being allowed to be relatively displaced in the front-rear direction;
a second pin that is provided in any one of the second rod and the retainer; and
a second pin insertion hole which is provided in the other one of the second rod or the retainer, and into which the second pin is inserted in a state of being allowed to relatively rotate around an own shaft while relative displacement in the front-rear direction is restricted;

the retainer rotates around the support shaft when the second rod is displaced in the releasing direction due to the opening operation to the second operation unit; and
the first pin insertion hole and the second insertion hole are formed to restrict the displacement of the second rod in the releasing direction due to the opening operation to the second operation unit in a case where the first pin is positioned at a predetermined position in the first pin insertion hole as the first rod is displaced in the releasing direction due to the opening operation to the first operation unit, and to restrict the displacement of the first rod in the releasing direction due to the opening operation to the first operation unit in a case where the first pin is positioned at the predetermined position due to the rotation of the retainer as the second rod is displaced in the releasing direction due to the opening operation to the second operation unit.

4. The double opening storage device according to claim 3 , wherein:
the first pin insertion hole extends in the front-rear direction such that the first pin is relatively displaceable by the displacement of the first rod in the front-rear direction; and
the second pin insertion hole is correlated to an outer diameter of the second pin in the front-rear direction such that the second pin is not relatively displaceable in the front-rear direction.
