In addition, the above-described elastic cyanine member is a process in which the upper side is locked to the protruding portion provided in the lower side of the engaging body 37 (see FIG. 4), and the elastic force is pressed against the sliding body 3〇 to move inward. It will increase, and the engaging body 37 can be swung in the direction of the locking position. This configuration is also the same in the latch device of Patent Document 2. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2001-262915 (Patent Document 2) Japanese Laid-Open Patent Publication No. 2001-262915 (New Issue) (The problem to be solved by the author) The latch device as described above is used in various types. When a device, a device, or the like is used in an excessively harsh environment such as ultra-low temperature, it is known that the following malfunction may occur. In this operation failure, even if the slider 30 is moved from the initial state of FIG. 5(a) to the press-fitting direction of (b), the engaging body 37 is not switched to the locking position as if it is rocking, but is maintained substantially. The phenomenon of the lock release position accommodated in the slider 30. The main cause of this phenomenon is that the pivoting portion (the shaft portion 37a and the shaft hole) of the engaging body 37 is at an ultra low/jnL ^ (7) dynamic resistance, which makes it difficult to shake. As a countermeasure against the above problems, the applicant of this case has made a lot of effort - to the technology of the second special = 2004-201050. This technique has a rib portion 28 that can be brought into contact with the pin portion 38c on the proximal end side of the engaging body to switch the engaging body from the locking position to the locking release position; The pressing movement of the body abuts against the pin portion, and the engagement body is mechanically changed from the locking release position + the knife to the casing-side inclined surface or the convex cam. However, in this configuration, it is known that when the sliding body is not pushed and moved to the vicinity of the final retracted position in the outer casing, the engaging body cannot be switched to the locking position, and the slope is not steep due to the steep slope of the slope and the cam. Feeling or feeling when moving. Therefore, the purpose of the present invention is to eliminate the above-mentioned problems and to prevent the malfunction in an excessively harsh use environment while maintaining a stable switching operation and feeling, and to improve the quality and to further expand the use. (Means for Solving the Problem), in order to achieve the above object, the creation system has: an outer shell; a sliding body having a "1" wheel groove arranged in a forward and backward state with respect to the peripheral device; The body is oriented toward the spring member that is pushed in the direction in which the outer beer is worn out, and the pivot is: the sliding body is described, and the claw on the front end side can be protruded from the sliding body. a locking position that is caught by the snap member and an engaging body that is substantially accommodated in the =1=stop release position, and a pin member that moves in accordance with the trajectory of the cam recess, the first four, and then The slider of the field is moved by the spring force of the spring member to move against the τ. The straw is held in the moved position by the cam groove and the 318541 8 M312583 piece, and the aforementioned engaging body is switched. The flash button device to the locking position is characterized in that the sliding body is in contact with each other during the movement of the spring member against the elastic force of the spring member, so that the engaging body can be switched from the locking release position to the locking position. And the slope 'its- The portion of the engaging body that is closer to the claw portion than the center of the swing and the corresponding portion of the outer casing is disposed on the other side. The creation of the m is preferably embodied in the following manner. The engaging member receives the spring member, and the engaging system can be switched from the locking position 2 to the locking position by the elastic force of the spring member, and the needle can be inserted due to the relationship between the abutting portion and the inclined surface. The position of the position (4) (4) of the position of the money (the second item of the scope of the patent application). The m of the wind is switched to the position of the card which is stuck by the buckled member, and is subjected to the orientation by the buckled member or the like. Card: == When the load is 'resistibly resisting the elastic force of the aforementioned elastic member, the third and fourth items can be enclosed.) The configuration of the positional direction switching is performed on the opposite side of the side opposite to the side where the claw is protruded. A triangular-shaped projection is used as the abutting portion, and the front surface is formed on the inlet side (the application effect (the effect of creation) ^ ^ in the patent scope of the first item of the creation of the towel, when the sliding body is pushed (4) Resist the elasticity of the component Move (4), the engagement function can be mechanically or forcibly switched from the locking release position to the locking position because the 2 318541 9 M312583 joint and the inclined surface are crimped and the other side will pass over the other side. The action U described in the problem is explained, and the engaging body is disposed such that the abutting portion and the inclined surface of the claw portion are closer to the claw portion than the rocking k to mechanically switch the locking position of the engaging body. Therefore, a good switching action can be achieved without damaging the feeling or feeling, and the quality can be improved. In the creation of the second application of the patent scope, the switching position of the engaging body to the locking position is the same as in the past by the elastic member In addition to the elastic force, it is mechanically or forcibly transmitted through the abutting portion and the inclined surface. In this case, the reliability of the operation switching characteristic can be improved without being affected by the use of the soil. In the creation of the third and fourth aspects of the patent application, for example, in the locking position of the first drawing (8) in which the engaging body is caught by the snap member, a predetermined large load in the drawing direction is applied to the buckled member. When the card body is anti-ballistic

That is, the main body 31 318541 13 M312583 is formed in a substantially door-shaped frame shape by the upper side 33a and the side edges 33b, and is formed by the upper side. An opening 33 is formed in the partition 33a and the side edges 33b (see Fig. 2). On the lower side, a shaft hole 33d is provided in a state in which the side edges 33b are penetrated, and a cylindrical portion 34 is provided between the side edges 33b. The tubular portion 34 is formed as a hole in which the upper side of the support shaft 26a and the spring member 45 can be loosely fitted, and has a projection 34b engageable with the guide groove 20a. a horizontal wall portion abutting against the striker 62; and a vertical wall portion extending downward from the left and right sides of the horizontal wall portion. The horizontal wall portion causes the both sides to protrude slightly outward from the main body 31, and The sliding portion is fitted in the state of the guiding recess 2 of the outer casing 2. The two sides of the vertical wall portion have a heart-shaped cam groove 5. The cam grooves 5 on the two sides are substantially the same shape, and are protruded from the longitudinal direction. (4) the convex cam island portion 35 of the central financial section; and the lower sides facing the longitudinal wall portion The fin portion 36a or the like is formed to be partitioned. The groove shape is as shown in Fig. 2, and the inducing groove 5a·' extending from the lower side toward the upper right side is located on the upper side of the inducing groove 5a, and is divided into left and right. The locking inducing lug groove 5b and the releasing inducing groove 5d; the concave locking groove 5c located on the lower side between the inducing grooves 讥, ^; and the returning from the inducing groove 5d toward the lower side In contrast, the engaging body 37 is constituted by the main body 38 and the claw portion 39 and the projection 37c as the abutting portion, and the claw portion 39 is located in the opening 33, except for the protrusion. All of the 37c are disposed between the main body W = the upper side 33a and the side edges 33b. That is, the main body (10) has a claw portion 39 protruding from the upper portion, and the lower portion 38b lacks the intermediate portion. When the upper core is disposed in the sash of the main body 31, the claw portion 39 enters the opening 33. The lower portion 38b 318541 14 M312583 is formed with two ribs 月 ^ ^ ', which are extended from the upper portion 38a, and has a shaft portion 37a located outside the lower jaws 38b and disposed between the upper and lower substantially double ports 1P, and A pin portion 38c on the lower end side is provided. Between the two lower portions "38b, there is provided a tab portion 37b which enters the aforementioned dam portion 34. The shank/large 37c is located on the opposite side of the claw portion 39 of the main body 38, that is, the main body ', 疋The left and right middle sides of the earthen lunar surface, and the upper side of the portion 37a are provided in a substantially triangular cross section. (Assembly) The above-described members are, for example, the engaging body 37 is first secured. This operation is performed from the state of Fig. 4 ...the shaft hole 33d is pushed into the inner side of the side of the side. Thus, the engaging body 37 is pivotally mounted with the shaft portion as a fulcrum to be rotated or rocked only in the shape range, and can be in the claw portion 39. The lock release state accommodated in the opening 33 and the lock state of the convex portion or the claw portion that protrudes from the inside of the opening 33 and press the striker 62 from above as shown in Fig. 1 (8) are switched. The reaction operating body 4 is disposed in the outer casing relative to the small frame portion 25, and is assembled into the outer casing from the frame, and is assembled to be rockable up and down in the state of the corresponding axial hole with the two sides _43 Next, the sliding body 3 〇 with the engaging body 37 is attached, that is, the mouth) The piece 3 will be assembled in the outer casing 2. This operation is preferably carried out by first mounting the elastic structure 2 on the support shaft (10) and forming the pin member 6 in a state in which the bottom wall 23 is kept rockable. Inside the outer casing 2. The pin member 6 is inserted into the outer casing by inserting the front end 6c of the both sides from each of the lock insertion holes 24b, and then forcibly moving the U-shaped intermediate portion 6a toward the elastic holding piece 23a and the hung side, thereby making the U-shaped intermediate The portion 6a is held between the elastic holding piece and the elastic holding piece. In this holding state, the pin member 6 is erected and held in the outer casing 2 318541 15 M312583, and the positions of the u-shaped side portions 6b are restricted to the limit. The longitudinal ribs 29" correspond to between the inner sides. Further, the 'pin member 6' can forcibly move the u-shaped intermediate portion 6a toward the side of the elastic holding piece 23a, 23b by inserting the front end portions 6c of the both sides into the outer casing from the locking insertion hole 24b, and the u-shaped intermediate portion The portion 6a is between the elastic holding piece 23b and the elastic holding piece (10). In this gripping manner, the lower 'locking member 6 is erected and held in the outer casing 2, and the position of the symmetrical u-shaped sides 46b is restricted between the restricting longitudinal rib 29 and the corresponding inner side. Further, when the latch member 3 is pushed into the outer casing 2, when the projection 34b k slope 20d falls into the guide groove 2〇a and is fitted, the state in which f cannot be extracted is assembled with respect to the outer casing 2. Here, the push-in process of the clasp member 3 is carried out, and the upper side of the spring member 45 enters the inside of the tubular portion and abuts against the tab portion 37b of the engaging body 37. Further, when the moving members 3 are urged to move toward the inside, the spring members 45 increase the elastic force, and the force causes the engaging body 37 to swing toward the locking position with the shaft portion 37a as a fulcrum. Further, both front ends 6c of the pin member 6 enter the groove entrance of the corresponding cam groove 5 (the groove extending downward from the return groove 5e). (Operation) The latch device i assembled as described above is in a state in which the claw portion 39 of the engaging body 37 is not seen when viewed from above, that is, the unlocked state. Further, the use state of the flash button device 1 is, for example, corresponding to the striker 62 of the movable body 61, and is attached to an appropriate position of the box-shaped base by the elastic locking claws 27 and the like. In the mounted state, the flash button is placed as shown in FIG. 2, and the button member 3 is moved by the spring member 45 (this movement is caused by the protrusion 34b abutting on the upper end surface of the guiding groove 2〇a). However, the claws 4 39 will be swung in the direction of the opening σ 33 (this shaking is achieved by causing the 318541 16 M312583 pin portion 38c to climb to the most-fastening member 3 of the rib 28). In this state, "When the elastic force of the member 45 is applied, the == pin 62 of Fig. 2 resists the impact of the latch member 3 in the direction of the mouth." During the initial stage of the movement, the projection 37c of the engaging body 37 abuts against the outer casing side: the card. The canine-like portion 37 of the body 37 is a mechanical point in the direction of the engagement position as a fulcrum, and the projection 37e elastically passes over the projection 37e. The inclined surface 20d "will prevent the front end of the striker 62 from being pulled out through the claw portion 39. Then, as shown in Fig. 1, the lock member 乂 and the card holder's center A end 6c are moved downward by the slider 30 port-々 And the above-mentioned induction groove 5& enters the locking groove 3b, and is locked in the locking concave when the pressing force for the flash button member 3 is released. 5c 关闭 关闭 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士 士Push the buckle member again; | pressure (release the push hand). In this way, the two members of the lock member 6 return to the groove inlet from the inducing recess 5a and the return recess 5e again from the inducing recess 5d and the return recess 5e, and simultaneously ask the buckle: the moving body 30 and the card. Fit 37) will switch to the original release position. In addition, the clicker device 1 of ^ is subjected to a vibration load in the up-and-down direction in the use state. The 'flash button member 3 is in a state of being pushed downwards' and may be released from the locked state due to a malfunction. The construction of this creation can prevent such a malfunction by the following actions. That is, when the structure of the present invention is subjected to a vibration load, the reaction operating body 4 is rotated by the shaft portion 318541 17 M312583 in the direction of the shaft (318 in the counterclockwise direction) against the elastic force of the spring pushing member 46. The position of the switch 42 is taken up by the receiving portion 42 to block the side 3 of the sliding body 3〇. The 30-way direction is the lower 33b & face, which prevents the sliding body from moving. It is to say that the front end 6c of the pin member 6 does not slide from the locking recess c to the release inducing groove 5d without accidentally releasing the locked state from the locking groove 5c. If the flash button device is used in a harsh environment such as a cold place, as described in the subject description, the engaging body 37 will not easily swing with the pivoting portion (the shaft portion 37a and the shaft hole 33d are fitted) as a fulcrum, and thus it is possible It is impossible to enter the normal locking operation, that is, to switch from the unlocked state to the locked state. However, in the above configuration, when the slider 3 is pushed by the striker toward the third arrow in the figure, As described above, in the initial stage of the pushing movement, the protrusion 37c of the engaging body 37 will Connected to the inclined surface 2〇d on the side of the casing, the bayonet body 37 is rocked toward the locking position by the shaft portion as a fulcrum due to the reaction force generated by the abutment. In other words, the engaging body 3?t is because of the sliding body. The pressing movement causes the projection 37c to abut against the inclined surface 2〇d on the outer casing side, and by the guiding action of the inclined surface 20d (the reaction force received from the inclined surface), from the substantially erected state, the shaft portion 37a is used as a fulcrum The device is mechanically switched to the locked position by rocking. Therefore, in the configuration of the present invention, the switching of the engaging body 37 from the unlocking position to the locking position and the switching from the locking position to the locking release position are mechanical or Since it is mandatory, even if it is a specification in an environment where the application is too severe, it does not cause malfunction or malfunction, thereby improving the reliability of the operating characteristics. Moreover, the structure of the creation In the case where the engaging body 37 is engaged with the striker 62, the latch 318541 of the first figure (b) 318541 18 M312583 is located at the position where the predetermined amount of load in the drawing direction is applied to the striker 62 side, since the engaging body 37 is pivoted (the shaft) Part 37a and the axis hole coffee The fulcrum is the fulcrum and the projection 37c enters into the groove of the guiding groove as the retracting portion, so that it is oscillated from the locking position toward the locking releasing position against the force of the magazine member (10). Therefore, the flash button device is also It will not be damaged by carelessness, etc. This creation is not subject to any restrictions on the above form, as long as it has the requirements specified in item 1 of the scope of the patent application, In the case of the various types of the Ai 4, a bevel may be formed on the side of the engaging body, and the protrusion as the abutting portion shall be provided on the side of the casing on the inclined surface. [Simplified description of the drawing] Fig. 1(a) to (C) shows the structure of the flash button position of the present creation form. The second figure shows the diagram of the latch diagram of Fig. 1. The structure of the door lock of α is placed at the position where the lock is released.
