Below, with Fig. 8 (a)～Fig. 9 the effect of above-mentioned locks for doors (anti-theft lock device) 101 is described.
Fig. 8 (a) is the lateral view of expression anti-theft lock device 1 locking state just often.Fig. 8 (b) is the front view of this locking state of expression.Though expression on the contrary about Fig. 8 (a)～Fig. 9 and Fig. 7, with Fig. 7 similarly, reveal is described as the front.Because the front view among Fig. 9 is same with Fig. 8 (b), thereby will illustrate omission.
In Fig. 8 (a) and (b), symbol 102 is that expression substrate, symbol 104 are that expression shell, symbol 106 are expression lockplate, symbol the 116, the 117th, and each incision hole, the symbol 182 of expression substrate 102 and shell 104 is expression applies the shell side of elastic force to lockplate 106 helical springs.Shell 104 be fixed be bonded on the substrate 102, substrate 102 is to be fixed on the cupboard side by fixed part 112.
Shown in Fig. 8 (a), lockplate 106 is to use the incision hole 119 of front to engage with the hook 115 of reveal, stage portion 121 by the rear end side of upper end (stage portion) 120a of the prominent board 120 of stopper arms 108 and lockplate 106 connects, and stops the rotation to the direction of unblanking of the lockplate 106 that caused by first wind spring 122.Stopper arms 108 by the effect of second wind spring 128 towards lockplate 106, bullet to the direction of unblanking.The direction of drawing in to plunger 130 is raised actuating arm 109 by solenoid 103 effects.
The front end 106a of lockplate 106 is in the position that is close with the vertical preceding board 102b of substrate 102, and the projection 114 of the rotation prevention usefulness of lockplate front end is close to the hole portion 118 that engages usefulness of preceding board 102b and only leaves a little distance, is on the position of subtend.Bullet rearward is in each rearward end of the slotted hole 110 (with reference to Fig. 7) of the slotted hole 181 of the bearing 134 on the shell 104 and substrate 102 to the fulcrum 105 of lockplate 106 by the effect of the helical spring 182 of the front side in the shell.
Fig. 9 be illustrated under the locking state of Fig. 8 (a) and Fig. 8 (b), the robber is with the door of utensil sledge cupboards such as sledge thick stick, the state that will open it.
Because it is door is moving towards the sledge of opening direction, the hook 115 of door shown in the arrow A among the figure, powerful ground draws lockplate 106 forward, make the fulcrum 105 of lockplate 106 overcome the elastic force of helical spring 182 and in slotted hole 110,181, move to the place ahead, make lockplate 106 and fulcrum 105 move to the place ahead with being integral, thus make the rotation of lockplate 106 stop the projection 114 of usefulness enter into substrate 102 preceding board 102b hole portion 118 and engage with it.Promptly, by the sledge evolution to powerful pulling force lockplate 106 is bitten in the substrate 102, become fully and can not move towards the direction of unblanking.
Like this, because on the basis that stops lockplate 106 coupling mechanism force that direction is rotated to unblanking, that forms by the butt of stopper arms 108 and lockplate 106, add again by rotating the projection 114 that stops usefulness and the engaging power (coupling mechanism force) thereby the energy of hole portion 118 stop the rotation of lockplate 106 to the direction of unblanking powerfully.
That is to say, because hole portion 118, promptly, because the preceding board 102b of substrate 102 has caught the rotatory force of lockplate 106, and the butt of the stage portion 121 of the stage portion 120a of stopper arms 108 and lockplate 106 also stops the rotation of lockplate 106, thereby can stop the rotation of lockplate 106 to the direction of unblanking powerfully, can keep the engaging of lockplate 106 and hook 115, can positively prevent to be opened by sledge.
Because members such as substrate 102 or lockplate 106, stopper arms 108, fulcrum 105 are to form with metal material respectively, thereby can be with the locking action at so-called two positions, promptly guarantee antitheft intensity fully by the locking action of the stage portion 120a of the stage portion 121 of the locking action of the hole portion 118 of the projection 114 of lockplate 106 and substrate 102 and lockplate 106 and stopper arms 108.
Since the butt surplus of the horizontal direction of the stage portion 121 of the stage portion 120a of the stopper arms just often 108 shown in Fig. 8 (a) and lockplate 106 is set for also bigger than the distance (gap) between the preceding board 102b of the front end 106a of lockplate 106 and substrate 102, thereby can guarantee shown in Figure 9 when the sledge door butt of the stage portion 121 of the stage portion 120a of stopper arms 108 and lockplate 106.For example when the sledge door, even the butt between stopper arms 108 and the lockplate 106 is disengaged, the power that also can be stoped lockplate 106 to rotate by the engaging of projection 114 and hole portion 118 fully can obtain antitheft power.
