Description

  The present invention relates to a push-open type locking mechanism.

  Vehicles such as automobiles are provided with various storage devices in the passenger compartment.

  In such a storage device, an opening / closing member (lid) is attached to the fixing member (storage container body) so as to be openable / closable, and the opening / closing member is held in a closed state between the fixing member and the opening / closing member. There are those provided with possible locking mechanisms.

  As such a lock mechanism portion, a push-open type using a claw portion and a latch device that alternately repeats gripping release operation on the claw portion by a pushing operation by the claw portion is used (for example, a patent) Reference 1 and Patent Document 2).

  In a normal case, the claw portion is attached to the opening / closing member side, and the latch device is attached to the fixing member side.

  In the push-open type locking mechanism described in Patent Document 1, the claw portion and the latch device are directly provided at the center in the width direction on the distal end side of the opening / closing member in the fixing member and the opening / closing member. Therefore, the claw portion and the latch device protrude to the outside, and the appearance is bad.

  On the other hand, in the push-open type lock mechanism described in Patent Document 2, the claw portion and the latch device are not protruded to the outside by providing the claw portion and the latch device on the lower side of the fixing member. Therefore, the deterioration of appearance is avoided.

For example, FIG. 8 shows a cup holder device as the storage device 1, and an opening / closing member 3 (lid body) is attached to the fixing member 2 (storage container body) so as to be openable and closable. Between the fixing member 2 and the opening / closing member 3, there is provided a lock mechanism portion 4 capable of holding the opening / closing member 3 in a closed state. This lock mechanism part 4 is provided in the back lower part of the cup holder device (storage device 1). The lock mechanism 4 is a push-open lock mechanism 7 that includes a claw 5 and a latch device 6. The claw portion 5 is attached to the opening / closing member 3 side, and the latch device 6 is attached to the fixing member 2 side. The claw portion 5 is installed at the tip of a long arm 8 or the like attached to the opening / closing member 3. Reference numeral 9 denotes a rotation center of the opening / closing member 3 (lid body).

  As described above, when the claw portion 5 is installed at the distal end of the long arm 8 or the like, the distance from the distal end portion of the opening / closing member 3 to the claw portion 5 becomes long. As a result, a new problem arises that the management of the surface difference becomes difficult. Thus, when the dimensional variation becomes large, the open / close member 3 is liable to be lifted when left in a high temperature state.

  Furthermore, when the distance from the front end portion of the opening / closing member 3 to the claw portion 5 is long, a loss occurs, which causes a problem that the reliability of the locking operation is lowered.

  In order to solve the above-described problem, in the invention described in claim 1, the opening / closing member is attached to the fixing member so as to be openable / closable, and the opening / closing member is closed between the fixing member and the opening / closing member. In a push-open type lock mechanism provided with a lock mechanism portion that can be held, the lock mechanism portion is attached to a locking recess formed on the front end surface of the opening / closing member and a corresponding position of the fixing member. A striker that can lock and release the locking device with respect to the locking recess, a biasing member that biases the striker in the release direction, and a protruding and retractable movement with respect to the fixed member. And a switch member that can be pushed in by an opening / closing member, and further, a locking device part is a claw part attached to the switch member, and a grip release to the claw part by a pushing operation by the claw part The latch device that repeats the operation alternately, and the striker can be held in a locked state against the biasing member when the switch member is gripped by the latch device, and the striker is held by the biasing member when the switch member is released by the latch device. A striker operating mechanism that can be retracted to a released state is provided.

  The invention described in claim 2 is characterized in that the striker operating mechanism is a slide guide portion formed between the switch member and the striker, and is a push-open type locking mechanism.

  The invention described in claim 3 is characterized by the push-open type lock mechanism according to claim 1 or 2, wherein the lock mechanism portion is provided at a center portion in the width direction of the fixing member and the opening / closing member.

  According to the first aspect of the present invention, the opening / closing member is attached to the fixing member so that the opening / closing member can be opened / closed, and the locking mechanism portion capable of holding the opening / closing member in the closed state is provided between the fixing member and the opening / closing member. In the push-open type locking mechanism, the locking mechanism portion includes a locking concave portion formed on the distal end surface of the opening / closing member and a locking device portion attached to a corresponding position of the fixing member, the locking device portion being A striker that can be locked / released with respect to the locking recess, a biasing member that biases the striker in the release direction, and a protruding member that can be stored in the fixing member, and is pushed by the opening / closing member. A switch member, and a lock device portion, a claw portion attached to the switch member, and a latch device that alternately repeats a grip release operation to the claw portion by a pushing operation by the claw portion, The striker can hold the striker against the biasing member when the switch member is gripped by the latch device, and can be retracted to the release state by the biasing member when the switch member is released by the latch device. By providing the mechanism, the following operational effects can be obtained. That is, since the latch device or the like is not protruded to the outside, it is possible to prevent the appearance from being deteriorated. In addition, the existing latch device can be used effectively.

  In the invention described in claim 2, the striker operating mechanism is a slide guide portion formed between the switch member and the striker, so that the striker operating mechanism is configured without providing a special member. Therefore, the cost can be reduced accordingly. Moreover, since the slide guide part can slide-guide the striker by using the pushing operation of the switch member, it can be configured such that the movement state is simple and reliable.

  In the invention described in claim 3, since the lock mechanism portion is provided in the center portion in the width direction of the fixing member and the opening / closing member, the distance from the tip end portion of the opening / closing member can be shortened. The variation of the surface becomes small, and the management of the surface difference can be facilitated. Since the size variation is small, it is possible to prevent the opening / closing member from floating even when left in a high temperature state. Furthermore, since the distance from the front-end | tip part of an opening-and-closing member to a nail | claw part becomes short, since there is little loss, the reliability of locking operation can be improved.

By providing the striker operating mechanism 43 that can retract the striker 31 to the released state by the biasing member 32 when the switch member 33 is released by the latch device 35, the following operational effects can be obtained.

  That is, since the latch device 35 and the like are not protruded to the outside, the appearance can be prevented from being deteriorated. Further, the existing latch device 35 can be used effectively.

  Further, since the striker operating mechanism 43 is the slide guide portion 44 formed between the switch member 33 and the striker 31, the striker operating mechanism 43 can be configured without providing a special member. The cost can be reduced accordingly. Moreover, since the slide guide part 44 can slide-guide the striker 31 using the pushing operation of the switch member 33, it can be set as the structure where a motion is simple and reliable.

  Since the locking mechanism portion 21 is provided at the central portion of the fixing member 14 and the opening / closing member 15 in the width direction 45, the distance from the distal end portion of the opening / closing member 15 can be shortened. It becomes small and management of surface difference can be facilitated. Since the dimensional variation is small, it is possible to prevent the opening / closing member 15 from floating even when left in a high temperature state. Furthermore, since the distance from the front-end | tip part of the opening-and-closing member 15 to the nail | claw part 34 becomes short, since there is little loss, the reliability of lock operation can be improved.
