For example, a lock device is provided at an open end so that a front grill of an air conditioner, a door of a dashboard of a car, and the like are not arbitrarily opened.

Conventionally, a means for restraining the opening of these members, that is, a locking device has a hook-shaped engaging member and a locking member for locking the same, and restrains the opening by engaging the two members. Generally, the members are moved directly or indirectly to shift the locking position to release the engagement, so that the members can be freely opened. In this case, a push button is often used as the operating means of the locking member, and a method of moving the locking point of the locking member by pressing the push button to disengage the engaging member has been adopted in many cases. I have.

By the way, this type of lock device can release the locked state, that is, the locked state, by pushing the push button (pulling the button in some cases). However, when the pushing operation of the push button is released, Since the stop member returns to the original position and engages with the engagement member again to be in a locked state, conventionally, when the lock is released once with a winding spring or the like interposed on the screwing side, the action of this spring is performed. To raise the door or the like to shift the position of the engaging member so that the locking member is not returned to the locked state even if the locking member is returned.

Lifting by this spring is an extremely effective means because it is not necessary to keep pressing the button, but in order to assemble the spring, it is necessary to select a place together with the work and prepare the space for it, In some cases, assembly is not possible.

[Problems to be Solved by the Invention] The present invention has the above-mentioned conventional problems, in particular, the fact that it is necessary to use a spring that is separate from the lock device and incorporate it into a door or the like in a separate operation, It has been devised for the purpose of improving this in view of restrictions such as the necessity to select a place where the assembly works effectively on the door etc. on the screw side of the door etc. It is.

[Means for Solving the Problems] Based on the above-mentioned object, the present invention raises a door or the like at the time of unlocking by a conventional spring by using a pressing slider built in a locking device and operating a button by operating a button. It is an object of the present invention to provide a lock device in which the engagement member is pushed out at the same time as the disengagement, and the lock device is prevented from being re-locked in conjunction with the operation of the button. To further describe the features of the present invention, the present invention relates to a member which forms a housing having a fixing means and an engaging member which is inside the base and which engages from the outside of the base. A locking member, a release button for releasing the locking state of the locking member, a pressing slider for receiving the engaging member and guiding the locking member toward the locking member; A spring that constantly presses and biases the outside of the base, the spring is contracted between the pressing slider and the locking member, and when the engaging member is latched, The compression member is compressed in accordance with the pushing of the pressing slider, and the engaging member is latched and restrained by the locking member. On the other hand, when the release button is released, the locking member is released from the locking member and the engagement member is disengaged. The engagement is released via the pressing slider by the compressed spring at the same time when the engagement is released. To provide a locking device which is characterized by being configured so as to push towards the timber out of the base body.

[Operation] From the above-mentioned configuration, for example, when used as a locking means of a door, the base of the lock device of the present invention is attached to the opening on the main body side, and the engaging member attached to the open / close free end thereof along with the closing of the door. When the pressing member is pressed, the pressing slider retreats inside the base body while compressing the spring due to the invasion of the engaging member, and the engagement between the engaging member and the locking member is achieved and the locked state is established. Next, in this state, when the locking of the locking member is released by operating the release button, simultaneously with this release, the engaging member receiving the repulsion of the pressing slider that has compressed the spring is pushed out. As a result, the door floats up from the opening on the main body side, and the engaging member moves away from the engaging position with the locking member.
