Dividing at a pair of keeping arm 11, between 12 has: first maintaining part 29 (also with reference to Fig. 6 (c), (d)) of the trigger 3 that can keep the portion that is pressed 18 of sliding part 13 is pushed, be configured in than first maintaining part, the 29 forward second distolateral maintaining parts 30.First maintaining part 29 and second maintaining part 30 form the space of cucurbit (wooden dipper bamboo utensil for holding cooked rice) shape.In addition, be provided with the 3rd cam surface 31,32 of pair of angled shape at the front end of a pair of keeping arm 11,12.
A pair of keeping arm 11,12 is provided with the four- cam face 33,34 of the pair of angled shape of a part of dividing second maintaining part 30.Along with movable body 1 moves to loop direction of action X2, when second maintaining part 30 broke away from, trigger 3 was to bring into play function via four- cam face 33,34 with the mode that a pair of keeping arm 11,12 backs down at trigger 3.
The characteristic part that becomes this embodiment is; Shown in Fig. 5 (b); When catcher 6 is positioned at the reference position; Make a pair of keeping arm 11,12 in above-mentioned under the effect of the power F (with suitable) that rotates from the chucking power of sandwich sliding part 13, sliding part 13 can not overcome active force G and the position of drawing back (the loop direction of action X2 side) of locking spring 14 and retreat.
Particularly; The normal L1, L2 of each first cam surface 19,20 and corresponding first cam follower surface 21,22 that is in the sliding part 13 of progressive position is set to following mode with respect to the size of the advance and retreat direction Y1 of sliding part 13, Y2 (direction of advance Y1, direction of retreat Y2) angulation θ 1, θ 2; Promptly; Make a pair of keeping arm 11,12 in above-mentioned under the effect of the power F (suitable) that rotates with the power of seizing on both sides by the arms from sandwich sliding part 13, sliding part 13 can not overcome the active force G of locking spring 14 and the position of drawing back is retreated.
The outlet operation step of the movable body 1 when next, Fig. 6 (a)～(d) expression is common.Move and arrive starting position (with reference to Fig. 6 (b)) voluntarily to outlet direction of action X1 by the position of loop direction of action X2 side from being positioned at if movable body 1 is such as Fig. 6 (a) shown in than starting position voluntarily; Then trigger 3 insert with movable body 1 in outlet direction of action X1 goes together mobile latch gear 4, thereby the portion that is pressed 18 of pushing sliding part 13.
Along with trigger 3 is pushed the portion of being pressed 18 and made sliding part 13 overcome active force and the position displacement of drawing back of locking spring 14; A pair of first cam surface 19,20 breaks away from the engaging of corresponding first cam follower surface 21,22, allow a pair of keeping arm 11,12 to interior to rotation.
Under the state that allows a pair of keeping arm 11,12 inwardly to rotate like this; Under the effect of second cam follower surface 27,28 of the holding section 23,24 that is arranged at the second cam surface 25a, 26b (with reference to Fig. 5 (b)) and each self-corresponding keeping arm 11,12 in each restraint portion 25,26; The active force of extension spring 7 converts to and makes a pair of keeping arm 11,12 to interior power to rotation; Shown in Fig. 6 (c), a pair of keeping arm 11,12 to interior to rotation.
Thus, at 11,12 capture triggers 3 of a pair of keeping arm, extension spring 7 shrinks, and thus, shown in Fig. 6 (d), makes movable body 1 from walking to release position, outlet.In addition, remove with the engaging of corresponding restraint portion 25,26 holding section 23,24 of each keeping arm 11,12, through extension spring 7 catcher 6 is urged to stop position.
The loop operation step of the movable body 1 when next, Fig. 7 (a)～(c) expression is common.If be in the state of release position, outlet from such movable body 1 shown in Fig. 7 (a) extension spring 1 elongation while movable body 1 that kind shown in Fig. 7 (b) is moved to loop direction of action X2, then catcher 6 is gone together mobile with movable body 1.
And; Shown in Fig. 7 (c); When movable body 1 carried out loop action to starting position voluntarily, along with the application of force of locking spring 14 makes sliding part 13 advanced position carry out displacement, a pair of first cam surface 19,20 backed down first cam follower surface 21,22 of the correspondence of a pair of keeping arm 11,12.Thus, a pair of keeping arm 11,12 outwards rotates.Consequently, the maintenance of 29 pairs of triggers 3 of first maintaining part is disengaged.In addition, the holding section 23,24 of each keeping arm 11,12 be arranged on matrix 5 on corresponding restraint portion 25,26 engaging, catcher 6 is maintained at the reference position.
Next, Fig. 8 (a)～(d), Fig. 9 (a)～(c) represent to automatically reset operation.That is, shown in Fig. 8 (a), be not configured in the catcher 6 of release position, outlet under the state of capture trigger 3 the catching failure of trigger 3, a pair of keeping arm 11,12 is in and has inwardly carried out the state that rotates.In this case, can make catcher 6 under the state of having caught trigger 3, automatically be reset to the reference position.
When making movable body 1 carry out the outlet action from the release position, outlet shown in Fig. 8 (a); Shown in Fig. 8 (b); The 3rd cam surface 31,32 butts of trigger 3 and a pair of keeping arm 11,12; Through its that kind shown in Fig. 8 (c) is backed down, then shown in Fig. 8 (d), trigger 3 is caught by second maintaining part 30 of front side.
Then, shown in Fig. 9 (a) and (b), make movable body 1 carry out the loop action towards starting position voluntarily, shown in Fig. 9 (c), when movable body 1 arrived voluntarily the starting position, trigger 3 backed down a pair of keeping arm 11,12, forwards breaks away from from second maintaining part 30.In addition, a pair of keeping arm 11,12 outwards rotates, and the holding section 23,24 of each keeping arm 11,12 be arranged on matrix 5 on corresponding restraint portion 25,26 engaging, catcher 6 remains on the reference position.Thus, easily realize automatically reseting.
According to this embodiment; When the movable body 1 that has carried out the loop action at from the outlet release position (with reference to Fig. 7 (a)) arrives voluntarily starting position (with reference to Fig. 7 (b)); Sliding part 13 advanced position that promptly locked spring 14 application of forces by for example compression helical spring are advanced, and a pair of keeping arm 11,12 outwards rotates.Thus, the maintenance of 11,12 pairs of triggers 13 of a pair of keeping arm is disengaged, and the holding section 23,24 of a pair of keeping arm 11,12 engages with restraint portion 25,26 collisions of matrix 5.
Even a pair of keeping arm 11,12 receives the impact counter-force (collision counter-force) of following this engaging, the power F (from the chucking power of sandwich sliding part 13) that a pair of keeping arm 11,12 is inwardly rotated can not make sliding part 13 overcome the active force G of locking spring 14 yet and the position of drawing back is retreated.Therefore, be not easy impacting small the beating of generation on a pair of keeping arm 11,12 or sliding part 13 under the counter-force, can significantly reduce the bruit de froissement of ear-piercing inside.
Particularly; When catcher 6 is in the reference position, be in the size that the normal L1, L2 of each first cam surface 19,20 and corresponding first cam follower surface 21,22 of the sliding part 13 of progressive position is configured to stipulate with respect to advance and retreat direction Y1, Y2 angulation θ 1, the θ 2 of sliding part 13.Promptly; The size of above-mentioned angle θ 1, θ 2 is configured to following mode; That is (for example approximate right angle) retreated in the active force that, can not make sliding part 14 overcome locking spring 14 because of the power F that above-mentioned impact counter-force causes making a pair of keeping arm 11,12 inwardly the to rotate position of drawing back.
More specifically; If angle θ 1, θ 2 in the scope of 85 degree～95 degree, then can prevent to retreat to the interior active force G that makes sliding part 13 overcome locking spring 14 to the power F (from the chucking power of sandwich sliding part 13) that the rotates position of drawing back because of above-mentioned impact counter-force makes a pair of keeping arm 11,12 reliably.Therefore, can further reduce the bruit de froissement of ear-piercing inside.
In addition, when such catcher 6 to trigger 3 maintenance failures is configured in stop position shown in Fig. 8 (a), can shown in Fig. 9 (c), that kind make catcher 6 automatically be reset to the reference position.Promptly; The state that is configured in stop position as if catcher 6 under the state of such not capture trigger 3 shown in Fig. 8 (a) begins to make movable body 1 to move to outlet direction of action X1, and the 3rd cam surface 31,32 that kind shown in Fig. 8 (b), (c) of a pair of keeping arm 11,12 of this state was backed down after then trigger 3 will inwardly rotate.Thus, shown in Fig. 8 (d), trigger 3 is caught by second maintaining part 30 of front side.Therefore, after this, can shown in Fig. 9 (a) and (b), that kind make movable body 1 carry out loop action starting position extremely voluntarily.
