Lock system
A lock system includes: a latch which is rotatably supported on a housing, and is brought into engagement with and disengagement from a striker; a spring for biasing the latch in a direction in which the engagement of the latch with the striker is released; a slide member which is rotatably supported on the housing, controls the rotation of the latch, and is an integrated molded part; a rotation preventing portion which prevents a rotation of the latch in a biased direction; a rotation permitting portion which permits the rotation of the latch in the biased direction; and a driven portion which links with a manual operation unit, wherein: the rotation preventing portion and the rotation permitting portion are provided at one end portion of the slide member; and the driven portion is provided at the other end portion of the slide member.
1. A lock system comprising:
a latch that is rotatably supported on a housing and brought into engagement with and disengagement from a striker;
a spring for biasing the latch in a direction in which the engagement of the latch with the striker is released;
a slide member that is rotatably supported on the housing, controls a rotation of the latch, and comprises an integrated molded part which is molded from a synthetic resin;
a rotation preventing portion that prevents the rotation of the latch in a biased direction;
a rotation permitting portion that permits the rotation of the latch in the biased direction, the rotation preventing portion and the rotation permitting portion are provided at one end portion of the slide member;
a driven portion, provided at an other end portion of the slide member, that links with a manual operation unit;
an elastic locking portion that is insertable into an insertion hole in the housing and prevents a dislodgement of itself from the insertion hole;
an elastic arm which is partially cut apart from the one end portion of the slide member;
an arc-shaped guide surface relative to the insertion hole; and
a vertical lock surface having an upwardly tapered shape,
wherein the elastic locking portion is provided at the one end portion of the slide member,
wherein the elastic locking portion comprises the elastic arm,
wherein a front end edge of the elastic arm comprises the arc-shaped guide surface, and
wherein a rear end edge of the elastic arm comprises the vertical lock surface.
2. A lock system comprising:
a latch that is rotatably supported on a housing and brought into engagement with and disengagement from a striker;
a spring for biasing the latch in a direction in which the engagement of the latch with the striker is released;
a slide member that is rotatably supported on the housing, controls a rotation of the latch, and comprises an integrated molded part which is molded from a synthetic resin;
a rotation preventing portion that prevents the rotation of the latch in a biased direction;
a rotation permitting portion that permits the rotation of the latch in the biased direction, the rotation preventing portion and the rotation permitting portion are provided at one end portion of the slide member; and
a driven portion, provided at an other end portion of the slide member, that links with a manual operation unit,
wherein the slide member is molded into a beam shape that exhibits a substantially rectangular cross section, and
wherein the cross section is twisted midway along the length of the slide member in such a manner that the cross section located in a vicinity of the rotation preventing portion is twisted in a direction in which the latch rotates from a released state to a locked state relative to the cross section in a vicinity of the driven portion.
