Under above-mentioned structure, will the operation of door lock assembly of the present invention be described.

Fig. 4 is the sectional view of door door lock assembly when closing; Fig. 5 is the sectional view of door door lock assembly when opening; Fig. 6 is the view of door mode of operation of door lock assembly when closing; Fig. 7 is the view of door mode of operation of door lock assembly when opening.

Shown in Fig. 4 and 6, in door 10 closing state, operation rod 80 is because the compression and the repulsion of spring 90 are pushed to doorframe 20 in housing 50, and like this, operation rod 80 is projected into the outside of housing 50 with latch bolt assembly 70.In this case, the active force that operating parts 82 is applied from spring 90 promotes, this spring 90 is arranged on the outer surface of bar 84 of operation rod 80, and therefore, the effect that the curved surfaces 78 of latch bolt assembly 70 is in rotatory force D1 down and therefore outstanding to doorframe 20.

At that time, the sweep 82b of the operating parts 82 of operation rod 80 and the space between the lead-in chamfered 82a are against the pressing surfaces 76 of latch bolt assembly 70.

By this way, if the first in command 12 is pulled along as shown in Figure 1 arrow 2 directions, perhaps the second in command 14 is pushed and opens door along arrow 2 directions, and directed force F 1 is applied on the leaf spring 65 that is arranged on operating lever 64 1 sides so.

Therefore, operating lever 64 rotates along direction D3 about hinge 63, and the operation rod 80 that is connected on the operating lever 64 is withdrawn along the direction D4 away from doorframe 20 with rectilinear motion.If operation rod 80 withdrawals, latch bolt assembly 70 has such space so, and it rotates about jointed shaft 72 in this space.At this moment, latch bolt assembly 70, is inserted in the housing 50 about jointed shaft 72 D2 rotation along clockwise direction thus by from the repulsion that is resisted against the doorframe 20 on the latch bolt assembly 70.Therefore, the state of door locked is released in mode steady and that open towards direction D5 easily.

In this case, be connected to the spring 62 on the operating lever 64 and all be provided with the spring constant of determining like this, that is, can apply the active force of the handle axle 11 of moving door around the spring 90 that operation rod 80 is installed.

According to the present invention, when first and

second handles

12 and 14 were pushed or spur with slight operating operation lever 64, latch bolt assembly 70 was rotated in the mode that is inserted in the housing 50 by reaction force.As a result, the lock-out state of door is easy to be released, and therefore only just can open the door reposefully by very little substantially power.

At this moment, do not need to rotate first and

second handles

12 and 14, therefore, handle has conventional spherical or straight shape, or ' A ' glyph shape as shown in Figure 1.In addition, handle of the present invention certainly has different shape.

If being in the active force that will be applied on

handle

12 or 14 under the open mode at door withdraws, operating lever 64 turns to its initial position by the active force of spring 62 so, compressive force and the repulsion and to doorframe 20 move of operation rod 80 by spring 90, and shown in Fig. 5 a, rotating latch bolt assembly 70 along direction D1, latch bolt assembly 70 stretches out from housing 50 like this.

On the other hand, if door 10 is closed once more, the lead-in chamfered 82a of more outstanding more than latch bolt assembly 70 so operating parts 82 just at first contacted doorframe 20 before door 10 is closed, then, the contact point of lead-in chamfered 82a and doorframe 20 is shifted to the curved surfaces 78 of latch bolt assembly 70.

In other words, if do not form lead-in chamfered 82a, the curved surfaces 78 of latch bolt assembly 70 contacts with the wall of doorframe 20 so, takies relatively large zone, forms higher substantially resistance thus.But if be provided with as lead-in chamfered 82a of the present invention, latch bolt assembly 70 can rotate gradually and move to the groove of doorframe so, and does not have bigger resistance.

Therefore, even the curved surfaces 78 of latch bolt assembly 70 has steeper bending relatively, latch bolt assembly 70 is under the help of the lead-in chamfered 82a of operating parts 82, also can slightly move gradually with the direction of operation rod 80 and spring 90 along door 10, the elasticity repulsion by spring 90 moves along the direction of doorframe 20 then.Therefore, latch bolt assembly 70 is fixed in the groove of doorframe 20, has obtained the lock-out state of door like this.

On the other hand, operating lever 64 further is provided with the leaf spring 65 that is formed on its free end.Under the situation of operation first and

second handles

12 and 14, leaf spring 65 is suitable for moving the operating point that is applied on the operating lever 64, so that improve the motion of operation rod 80 thus.

Fig. 8 cuts open the sectional view of getting along Fig. 4 center line A-A.As shown in Figure 8, the jointed shaft 72 of latch bolt assembly 70 is inserted in the recessed hinge 54 of housing 50, and the operating parts 82 of operation rod 80 is fitted in the latch bolt assembly 70.

Fig. 9 and Figure 10 are the views of mode of operation of the auxiliary lock assembly of door lock assembly of the present invention.Auxiliary lock device 100 of the present invention adopts when door is closed.As shown in Figure 1, the operating axis 106 of auxiliary lock assembly 100 links to each other with the external key device 108 of door lock assembly of the present invention.

As shown in Figure 9, in door lock assembly of the present invention under the not operated situation, operating axis 106 rotates along direction A1 at auxiliary lock assembly 100.At this moment, the ledge 106a that is formed on operating axis 106 1 ends is resisted against on the stop part 104, and stop part 104 moves along direction A2 like this.Therefore, the stop projection 104a that is formed on stop part 104 1 ends discharges from latch recess 84a.

As shown in figure 10, on the other hand, in door lock assembly of the present invention under the operated situation, operating axis 106 rotates along direction B1 at auxiliary lock assembly 100.At this moment, the ledge 106a that is formed on operating axis 106 1 ends is resisted against on the stop part 104, and stop part 104 moves along direction B2 like this.Therefore, the stopper protrusion 104a that is formed on stop part 104 1 ends is locked among the latch recess 84a.

Therefore, when the stop projection 104a of stop part 104 was locked among the latch recess 84a of operation rod 80, operation rod 80 was not along the longitudinal movement.The result is that latch bolt assembly 70 does not rotate, and therefore is in the safety locking state.

According to the present invention, this door lock assembly is made easily by less relatively parts, and shows substantially very low fault rate.

And door lock assembly of the present invention does not need the operation of swing handle, and handle can be designed to the different shape except conventional spherical or straight shape like this.

In addition, door lock assembly of the present invention only just can be opened door by the active force of less relatively promotion or pull handle, this make children or weakling can with convenient and stably mode open door.

As previously mentioned, the invention provides a kind of like this door lock assembly, it only just can must open and close door easily by less relatively linear force (that is, by promoting or pull handle along a direction).
