Description

Locking device having safety function and receipt device for moving vehicle

The present invention relates to a lock device and a storage device for a lock which have a safety function, which is specifically called a push / push mechanism for locking a moving object by a push operation and releasing the lock by a next push operation. It is about.

Fig. 9 shows a conventional example (described in Japanese Patent No. 2968490) to which a push / push mechanism is applied among lock devices, where (a) shows a locked state, and (b) shows a lock release process. The movable body (holder plate) 51 is press-fitted in the storage position direction C against the case (frame) 50 against the holding force of the holding means not shown, and is projected as the use position by the holding force. It is moved in the direction O to become a use position. The lock device 52 includes a cam member 53 formed on the case 50 and a finger spring 55 holding the cam member 53 in one direction, and a trace pin 54 provided on the movable body 51. It is made of a), it is made of a push-push catching mechanism that can move the movable body 51 to the storage position by a push operation that resists the fingering means, and can release the latch by the next push operation.

The cam member 53 is demarcated by the whole piece 56 and the longitudinal slit 57. It consists of a back piece 58. The whole piece 56 includes an inclined cam surface 56a forming a front edge, a locking concave cam groove 56b formed in a part of the rear edge, and a straight inclined cam groove 56c extending in the front-rear direction. Have The rear piece 58 has an axial attachment hole formed in the center portion, a projection 58a protruding from the front edge toward the locking concave cam groove 56b, and abutting projection 58b protruding from the rear edge. . And the cam member 53 is rotatably supported by the case 50 via the shaft S in the state which made the whole piece 56 facing the case entrance side. The edge spring 55 is caught by the stopper 59, one end of which is caught by the cam member 53 while the other end thereof is protruded on the case 50 side while being held by the shaft S. And the cam member 53 is hardened so that it may turn clockwise as shown in FIG. 9 (b) by the holding force of the finger spring 55 until the contact protrusion 58b contacts the corresponding end of the stopper 59. As shown in FIG. have.

The operation of the lock device 52 described above is as follows. When the movable body 51 is press-fitted into the case 50 by push operation, the trace pin 54 abuts against the inclined cam surface 56a, and then the cam member 53 uses the axis S as the point to hold the tangent spring ( While turning against counterclockwise, it turns to concave cam groove 56b. When the pressure input is released, the cam member 53 pivots slightly in the clockwise direction by the force of the tangent spring 55, so that the trace pin 54 moves to the inner angle of the concave cam groove 56b as shown in Fig. 9 (a). It is located in i) and becomes locked. The movable body 51 is locked to the storage position by resisting the finger holding means in the locked state. When the movable body 51 is taken out from the case 50, the movable body 51 is pushed again. Then, the trace pin 54 shifts from the concave cam groove 56b to the linear inclined cam groove 56c side in accordance with the turning of the cam member 53 in the clockwise direction (unlocking). When the pressure input is released, the trace pin 54 moves along the linear inclined cam groove 56c, while the movable body 51 is moved in the protruding direction, which is a use position, by the holding force of the holding means.

In the above conventional lock apparatus, when the case 50 is installed in the vehicle compartment, the moving body 51 in the storing position is press-fitted by the inertial force generated by a sudden brake or a collision, and is pushed in the same manner as the push operation. There is a fear that the lock is released and protrudes forward. As a conventional countermeasure, for example, the inertial stopper 60 is provided in the corresponding portion of the case 50. The inertial stopper 60 is thinly formed in the front-rear direction, guided by the pair of L-shaped guides 61 installed in the case 50 so as to be moved back and forth by a predetermined range, and at the same time in the coil spring 62. It is in the state pushed forward. Usually, it does not act on the cam member 53, as shown to FIG. 9 (a), (b). When the inertia force is received by the sudden brake or the like when the lock state of the lock device 52 of FIG. 9 (a), that is, the movable body 51 is in the stowed position, the inertia stopper 60 resists the coil spring 62. Backwards, as shown by the imaginary line of FIG. 9 (a), the cam member 53 approaches the corresponding side of the inclined cam surface 56a. That is, the lock device having the above safety function is press-fitted in the same manner as the moving body 51 is push-operated by the inertia force received by the collision or the like so that the trace pin 54 tries to move away from the concave cam groove 56a. In addition, the inertial stopper 60 also receives the inertial force and moves in the same direction to prevent the cam member 53 from turning in the unlocking direction, thereby preventing inadvertent unlocking.

By the way, the said moving body 51 may be assembled to the cover body which turns to a horizontal state and a standing state as shown, for example to FIG. 6 thru | or 8 which applied this invention. In the standing state of the lid, since the inertial stopper 60 is arranged in the up-down direction rather than the front-back direction, it does not exert its function, that is, for example, a person who rides the body touches the movable body to push the movable body. Similarly, when press-fitted, the lock by the cam member 53 and the trace pin 54 is released, and the movable body 51 inadvertently protrudes upward. This malfunction not only impairs the performance and reliability of the product, but also becomes dangerous in narrow vehicles.

This invention aims at eliminating the above subjects by a simple structure. Specifically, when the movable body is assembled to a cover body or the like that is rotated between the horizontal state and the standing state, the inadvertent unlocking of the push-pushing mechanism in the standing state, that is, the lock having excellent safety function with excellent performance and reliability by eliminating malfunctions In addition to realizing the device, the use of the lock device can be expanded to include various storage devices. Other objects will be clarified sequentially in the following description.

It has a pendulum 30 which makes it impossible to release the said latch by preventing the said rotation of the member 21, It is characterized by the above-mentioned.

The above structural feature is that the pendulum 30 approaches the counterpart side of the cam member 21 by its own weight to prevent turning of the cam member 21 while the case 3 is rotated from the horizontal state to the standing state. By doing so, the movable body 10 receives a downward careless load, i.e., a load similar to a push operation, to prevent an operation of releasing the engagement (engagement) between the cam member 21 and the trace pin 22. The pendulum 30 is simple because the case 3 protrudes due to its own weight during the standing state, and is also used for the turning operation of the cam member 21 in the process of turning the case 3 back to the horizontal state. Step back out of the way. Therefore, the lock device 20 of the present invention is suitable for the storage device 1 for a vehicle installed in an automobile, a train, a ship, an airplane, etc., as particularly exemplified in claim 4.

In this structure, the shape of the pendulum 30 is specified, and the pendulum 30 rotates and protrudes the shaft 31 of the attachment portion 32 to the point in the standing state of the case 3 and the movable body 10. Is placed. In addition, the weight of the weight 33 may be secured to the thickness of the weight of the pendulum 30 itself, or a weight attaching part may be formed and a dedicated weight member having a large specific gravity such as metal may be attached thereto.

Second, the pendulum 30 is disposed in the recess 19 formed in the case 3 or the movable body 10 and rotates from the recess 19 in the standing state to protrude. In this structure, when the pendulum 30 is disposed in the recess 19, the cam member 21 does not interfere with the turning operation of the cam member 21 in the horizontal state. It is easy to protrude toward the counterpart side.

In addition, in the present invention, the case 3 is used in a broad sense, and is constituted by the rotational lid 3 or the like as illustrated in FIGS. State is also included.

It is engaged with the stepped part 3c on the cover 3 side. The lid 3 is held in a floating state on the console body 2 by its engagement. When opening the cover body 3, when the operation lever 6 is rotated in the direction of the arrow by the handle portion 6a of the front end, the lower end projection 6b presses the pressing member 7 downward and presses it. As the member 7 moves downward, the locking member 8 is moved to the front non-locking position against the holding force of the spring 9b.

[Case and Moving Object] The above-described storage device 1 is a center console provided in a vehicle compartment. In the relationship with the present invention, the lid 3 is an example of a case, and the cup holder 10 is an example of a moving object. Among them, the lid 3 forms a storage space 3C in which the cup holder 10 is placed between the upper and lower halves 3A and 3B, which are integrated in a housing structure. At least, the receiving member (3c) attached to both sides and extending in the front-rear direction, the gripping means (12) located on the front side of the lower half body (3B) and attached to a recess (not shown); , The trace pin 22 which protrudes toward the lower side is built in the rear side of 3 A of upper half bodies.

The holding means 12 holds the cup holder 10 in the protruding direction by hanging the lead end 13a of the coil spring 13 drawn out from the housing to the rear side of the cup holder 10. Therefore, the cup holder 10 is guided to the guide member 11 by the holding force of the coil spring 13 from the storing position of FIG. 7 when the locking device 20 to be described later is released. The slide is automatically switched to the use position of Fig. 8 which protrudes more than the front opening of 3). The cup holder 10 here comprises a thick plate-shaped main body 15, two rings 16 attached to both sides of the front end of the main body 15 through a shaft 17, and each ring 16. As shown in FIG. ) Has a spring 18 for holding the circular arc in FIG. 8, a lock device 20, a pendulum 30, etc. formed on the rear side of the main body 15. In addition, both rings 16 are composed of a fixed arc body 16a and a movable arc body 16b, and each of the free ends of the fixed arc body 16a is connected by an operation unit 16c. have. In this structure, in the storage position of FIG. 7, the movable circular arc body 16b overlaps with the fixed circular arc body 16a side, and the operation part 16c opens the front opening of 3 C of storage space parts. It is closed while matching the cotton. In the use position of Fig. 8, the movable arc body 16b is separated from the stationary arc body 16a by the holding force of the spring 18, and a cup holding hole is provided between the stationary arc body 16a. Form.

The lid 3 as a case, the cup holder 10 as a moving body, and the holding means 12 as a moving body are the structures described in Japanese Patent No. 2968490 and Japanese Utility Model Publication No. Hei 6-60528 as examples of the present invention. There is no obstacle. Even in such a case, however, the recess 19 is formed in the main body 15 of the cup holder 10 corresponding to the pendulum 30. The recess 19 is formed on the rear upper surface of the main body 15, and the pendulum 30 has a margin and does not protrude from the upper surface of the main body 15 in a state where the pendulum 30 is accommodated. As described later, the pendulum 30 may satisfy the condition such as to be attached through the shaft portion 31.

[Locking Device] The locking device 20 and the pendulum 30 for the safety function are formed in a set in the cover 3 and the cup holder 10 as shown in FIG. 1. Among these, the locking device 20 includes a cam member 21 formed on the main body 15 of the cup holder 10, a protrusion trace pin 22 formed on the lid 3, and a cam member 21. ), And a cup holder 10 is caught in the storage position by a push operation that resists the fingering means 12, and the latch is released by the next push operation. It consists of a push and push mechanism. Here, the trace pin 22 is attached to the rear inner surface of the upper half body 3A of the lid 3, and projects downward toward the storage space portion 3C side. The cam member 21 consists of the back piece 28 bordered by the whole piece 26 and the longitudinal slit (cam groove slit) 27. As shown in FIG. The whole piece 26 extends in the front-back direction, and the inclined cam surface 26a which forms the cross section of the front edge which forms the sickle shape, the recessed concave cam groove 26b formed in a part of the rear edge. Has a straight inclined cam groove 26c for release. The rear piece 28 has a projection 28a protruding from the front edge toward the concave cam groove 26b, a contact projection 28b protruding from the rear edge, and an attachment hole 28c formed in the center portion. . The cam member 21 is pivotable through the shaft 24, the washer 25, and the like on the rear upper surface of the movable body 10 with the entire piece 26 facing the rear side of the movable body 10. Is attached. The stopper spring 23 is held around the shaft 24 so that one end 23a is caught by the corresponding side of the cam member 21 and the other end 23b is formed by a stopper protruding from the cup holder 10 side. 29)). The cam member 21 is also supported by the holding force of the tangent spring 23 until the abutting projection 28b abuts against the corresponding end of the stopper 29 in a state where the trace pin 22 does not abut. It is hardened so as to turn clockwise as in 3 (a).

[Operation of Lock Device] FIGS. 3 to 4 show the operation of the lock device 20 described above. When the lock device 20 press-fits the cup holder 10 into the lid 3 by push operation, the inclined cam surface 26a contacts the trace pin 22 on the lid 3 side, and the cam member. As shown in Fig. 3 (b), the trace pin 22 is received into the concave cam groove 26b while turning against the stop spring 23 against the stop spring 23 as shown in Fig. 3 (b). When the pressure input is released, the cam member 21 pivots slightly in the clockwise direction by the holding force of the tangent spring 23 as shown in Fig. 4 (a), and the trace pin 22 is the inner angle of the concave cam groove 26b. It is located in the locked state. For this reason, the cup holder 10 is locked to the storage position against the holding means 12 in the locked state. When the person who rides the vehicle wants to use the cup holder 10, the cam member 21 is slightly removed by touching the operation portion 16c of FIG. 7 and pushing the cup holder 10 and then releasing it. While moving forward, the locking force with the trace pin 22 is weakened, and by turning the clockwise direction as shown in Fig. 4 (b) by the holding force of the finger spring 23, a straight inclined cam groove 26c is formed from the concave cam groove 26b. Go to the) side. After that, since the cup holder 10 slides in the forward protruding direction (used position) by the holding force of the holding means 12, the cam is moved while the trace pin 22 moves along the linear inclined cam groove 56c. Away from the member 21. The push and push mechanism may be provided with the cam member 21 on the lid 3 side and the trace pin 22 on the cup holder 10 side as in the conventional structure.

Pendulum 30 is a safety mechanism pendulum 30 is formed in the cup holder 10, the cover body 3 in the process of rotating from the horizontal state of Figure 6 (a) to the standing state of Figure 6 (b) By approaching the corresponding side of the cam member 21, the locked state of the cam member 21 is impossible to release. 5 shows details of the pendulum 30, (a) is a bottom view of the pendulum, (b) is a side view of the pendulum, (c) is a cross-sectional view taken along line AA of (a), and (d) is ( It is sectional drawing of the BB line | wire of b). 1 to 4 show the pendulum 30 in a schematic state. The pendulum 30 is composed of an attachment portion 32 and a weight portion 33 having a shaft portion 31, and are generally narrow in shape and long in shape before and after. As for the weight part 33, while the inside 34 is formed in hollow, the front side is deep up and down, and is decreasing in depth as it goes to the attachment part 32. As shown in FIG. In terms of material, it is a resin molded product, but metal can also be used. In addition, the weight portion 33 can secure the load by separately attaching the weight 35 to the inside 34. The pendulum 30 is rotatably attached to the recess 19 formed in the cup holder 10 as shown in FIG. 1 through the shaft portion 31. The recess 19 is formed in the front-rear direction along the side of the cam member 21, and has a size in which the pendulum 30 is accommodated with a margin and does not protrude from the upper surface of the cup holder 10. .

[Operation of Pendulum] FIG. 2 shows the operation of the pendulum 30. That is, the pendulum 30 has the shaft portion 31 as shown in FIG. 2 in the process in which the lid 3 is rotated from the horizontal state of FIG. 6 (a) to the standing state of FIG. 6 (b) as described above. ) Rotates to the point, and the weight portion 33 protrudes out from the recess 19. This protruding operation is automatically rotated by the weight of the pendulum 30 along with the standing state of the lid 3. In this embodiment, the inclination angle of the lid 3 is set to about 100 degrees, and at the inclination angle, the pendulum 30 is rotated by its own weight so that the weight 33 can protrude so that the safety function described later can be exerted. have. However, in various tests, the safety function can be satisfied when the lid 3 is rotated at least 95 degrees in the standing direction in accordance with the overall dimensions of the pendulum 30 and the load setting. Theoretically, when the cover body 33 exceeds 90 degrees in the standing direction, it protrudes from the recess 19, and a safety function can be obtained. In other words, when the pendulum 30 protrudes from the recess 19, the pendulum 30 approaches the corresponding side of the cam member 21, thereby preventing the cam member 21 from turning. Thus, if the cam member 21 is prevented from turning by the pendulum 30, it cannot switch from the locked state of FIG. 4 (a) to the unlocked state of FIG. 4 (b). For this reason, the lock or the locking state is reliably maintained as long as the lid 3 is not rotated to the horizontal state once again. Therefore, in this structure, even in the standing state of the lid 3, even if a person who rides on the operation unit 16c touches or touches cargo, that is, the same situation as when the lock is released, the locking device 20 ) Does not malfunction and release locks or jams. As a result, not only the reliability of the lock device 20 but also the reliability of the product performance as the storage device 1 and the cup holder 10 are further improved and the product is excellent in safety.

In addition, the present invention can be variously modified on the basis of the basic form described above except for the technical elements described in claim 1. In particular, the movable body is not limited to the cup holder 10, which is a form example, and may be, for example, a storage tray or various sliders that are moved with respect to the case or the lid 3.

As described above, the lock device having the safety function of the present invention has a higher operating quality than a conventional product by eliminating the possibility that the locked state is released even by the inadvertent load which can be directly or indirectly received in the standing state of the moving body. It is possible to extend the use of this kind of push / push mechanism.

In addition, the stowage storage device of the present invention can more reliably eliminate risk factors caused by inadvertent locking, that is, malfunction of the moving body and further, inadvertent protrusion, thereby improving safety and reliability of the device. have.
