Like this, when fork 29 is rotated towards open position, then as Fig. 7 (A), (B) shown in, the teat 36 that moves moves towards bear the direction that portion 51 leaves from the action of trace 47, thereby pressured quilt is removed gradually.Its result, trace 47 is clockwise rotated by the power that the applies edge of trace force application spring 50.Then, when fork 29 surpasses the semi-closure lock position and turns to open position one side, pressured 55 of trace 47 portion that is touched 72 that contact keeps bar 66 then.Then, by the power that applies of trace force application spring 50, the power that applies that keeps bar 66 to resist interlock spring 70 via trace 47 is along rotating counterclockwise.Its result keeps the engaging teat 71 of bar 66 and the engaging of opening the slot 64 of bar 56 to be disengaged.Thus, open bar 56 under the effect of the power that applies of opening bar force application spring 59 and be reset to off position.Like this, bear the pressured of portion 46 based on the operation of the pawl device bar 43 of the operating portion 63 of opening bar 56 and be disengaged, therefore, under the effect of the power that applies of pawl device force application spring 41, pawl device 37 and pawl device bar 43 turn to clamped position.Its result, the state shown in pie graph 1 (A), (B) and Fig. 2 (A), (B).
In addition,,, open bar 56, make to keep bar 66 along clockwise rotating, thereby keep bar 66 and open bar 56 and engage along clockwise rotating then with similarly above-mentioned with semi-closure lock state of operation door handle.In addition, open bar 56 pressured pawl device bars 43, make pawl device bar 43 along rotating counterclockwise.Like this, pawl device 37 rotates counterclockwise with pawl device bar 43 one edge, with the releasing that engages of fork 29.Its result, fork 29 rotates counterclockwise towards the open position edge.
In addition, under open mode, under the situation behind the operation door handle, open bar 56 edges and clockwise rotate, thereby make pawl device bar 43 along rotating counterclockwise.Like this, pawl device 37 rotates counterclockwise with pawl device bar 43 one edge.But, owing to the engaging of pawl device 37 and fork 29 is disengaged, so fork 29 is without any rotation.In addition, because trace 47 is removed the position application of force to engaging, will keep bar 66 to removing the position application of force, so even open bar 56 to the open operation rotated position, only the extension of interlock spring 70 can not make and keep bar 66 to rotate.Therefore, keep bar 66 and open bar 56 and can not engage.
Like this, in door lock assembly of the present invention, when temporary transient open operation is opened bar 56, then fork 29 surpass from locked position of coupler the semi-closure lock position during, keep bar 66 and open bar 56 and engage, remain on the open operation position thereby open bar 56.Therefore, can be via opening bar 56 with on the release position that pawl device 37 remains on not in advance with fork 29 engages.Like this, when open operation is opened bar 56, can stop fork 29 to engage with pawl device 37, can prevent to form semi-closure lock state in the semi-closure lock position.
In addition, keep bar 66 to form the structure of operating by to the power that applies of the trace force application spring 50 of trace 47 application of forces.And trace 47 is by the direction application of force to contact fork 29.Therefore, trace 47 can not prevent the opening operation of fork 29.Like this, fork 29 is moved swimmingly towards open position.Its result can carry out an open operation swimmingly.In addition, owing to form the structure of utilizing trace 47 and keeping bar 66 these two parts maintenance open states, so need not be configured on the same plane with opening bar and fork 29 and pawl device 37.Therefore, can provide and have the door lock assembly that semi-closure lock prevents the compactness of function.
In addition, door lock assembly of the present invention is not limited to the structure of above-mentioned embodiment, can carry out various changes.
For example, in the above-described embodiment, fight each other by the operation of door handle and to start 56 to carry out open operation, but be not limited to this, also can make its action by lock core or electric actuator.At this, in the above-described embodiment, only open bar 56 and move to the open operation position by making, then can prevent to form when open semi-closure lock state, so make by electric actuator under the situation of opening bar 56 actions, as long as move to the short time of open operation position, the electric actuator action is got final product so that open bar 56.That is,, need not keep the action of electric actuator, will open bar 56 and remain on the open operation position, so can reduce to consume electric power with the time to a certain degree for fear of semi-closure lock state occurring.
That is, in door lock assembly in the past,, need keep the action of electric actuator, will open bar and remain on the open operation position with the time to a certain degree for fear of semi-closure lock state occurring.But, owing to keeping the action of electric actuator, opening bar and be maintained under the state on the release position, fork and pawl device form the state that can not engage, so during the action of keeping electric actuator, even temporary transient open door, latching door again, fork can not be remained on the locked position of coupler, existence can not form door the problem of full-shut position.In addition, in door lock assembly in the past, after the temporary transient action of electric actuator, temporary transient do not carry out the opening operation of door and be placed, then the action of back electric actuator stops at the appointed time, forms the state that fork and pawl device can engage once more, even will open door afterwards, fork and pawl device are in the engaging of semi-closure lock position, and existence can not be carried out the problem of the open operation of door.
With respect to this, in the above-described embodiment, as mentioned above, open bar 56 because by keeping bar 66 machineries to remain on the release position, so even after door is become full-gear from full-shut position, under the situation of direct latching door, also can make door become full-shut position.In addition, open bar 56, owing to before fork 29 surpasses the semi-closure lock position from locked position of coupler, remain on the release position by maintenance bar 66, even after the electric actuator action, the open operation of door is not temporarily carried out and is placed, also can avoid fork 29 and pawl device 37 in the engaging of semi-closure lock position, can carry out the open operation of door.In addition, as mentioned above, because the not free restriction of the switching of door, institute is so that open electric actuator that bar 56 moves and also can carry out remote-controlled operation by remote controller etc. and make its action.
