Has a function of applying a biasing force to the weight 49 and holding the weight 49 in the slide shaft 51 of the mounting board 45. The piston part 41 of the piston rod 39 has substantially the same structure as the piston part 26 of the upper slide holder 12, as shown in FIGS. Inserted together with the lower urging spring 6 as urging means, the front end of which is provided with a wide annular groove 56 in front and rear,
An O-ring 57 is fitted into the annular groove 56, and a pair of exhaust grooves 58 are formed on both upper and lower sides near the base end of the annular groove 56. On the other hand, the lower cylinder 16 of the cover member 14 is provided with an orifice 59 on its rear surface, and the orifice 59
A filter 60 for purifying air sucked in from the inside is provided. Next, the structure of the lid 8 will be described. As shown in FIG. 1, the lid 8 is in the form of a thick plate, and has a triangular shape having shaft holes 61 at both left and right end portions on the inner surface thereof. A pair of raised left and right ribs 62, 62 are protruded, and a pair of connecting pieces 63, 63, which are closely opposed from almost the center and have an axis within the opposed interval, are protruded, and the whole is made of plastic. It is formed by integral molding. As shown in FIG. 3, shafts 37 projecting outward from the front edges on both sides of both mounting portions 34 of the lower slide holder 7 are fitted into the shaft holes 61 of the ribs 62. As shown in FIG. 4, the connection piece 63 supports one end of a joint 64 and the other end of the joint 64 is connected to a piston rod 39 passing through the central cylindrical portion 33 of the lower slide holder 7. Pivoted on part 40,
The lid 8 and the piston rod 39 are interconnected via a joint 64. The joint 64 is integrally formed of plastic, and a plate spring 65 extending obliquely backward is integrally protruded from the lower surface thereof. The joint 64 is elastically attached to the inner surface of the lid 8 by the plate spring 65. Contact (No. 4, 6
Figure). A joint cover 66 is placed over the joint 64 from above, and a tension spring 67 is provided between the joint 64 and the joint cover 66.
(Figs. 5 and 7). On the other hand, an anti-vibration device is provided on the bottom surface of the housing 4 so as to elastically contact the inner lower end of the lid 8. As shown in FIGS. 15 and 16, the anti-vibration device includes a pair of protruding edges 68 ', 68' protruding in a U-shape from substantially the center of the bottom surface of the housing 4 and projecting inward from both lower ends thereof. A guide frame 68 having
A pressure member 69 inserted between the lower surface of the guide frame 68 and the protruding edge 68 ′ and slid in the front-rear direction; and a vibration-proof spring 70 for urging the pressure member 69 in a direction of protruding from the guide frame 68. Consists of As shown in FIG. 15, the pressing body 69 is provided with a pair of claw pieces 71, 71 on both left and right sides of the upper surface thereof, and
The two pawls 71 are prevented from slipping forward from the guide frame 68 received at the front end of the guide hole 72 by protruding into a pair of guide holes 72 provided long in the front-rear direction on the upper surface (FIG. 16). Next, the storage device 1 assembled as shown in FIG. 2 is used by assembling it with a cassette deck and other audio devices (not shown) in a center panel (not shown) in the vehicle interior. First, in order to open the lid 8 which is closed as shown in FIG. 2, the front surface of the lid 8 may be slightly pushed in by hand. When the lid 8 is pushed in, the piston rod 39 retreats in the central cylindrical portion 33 of the lower slide holder 7 via the joint 64, and the piston portion 41 moves the lower urging spring 6 into the lower cylinder 16 of the cover member 14. It is pushed slightly against the urging force. The position of the cam groove 9 changes with the retreat of the piston rod 39, and the trace shaft 44 of the lock pin 10 is at the stop d in the cam groove 9, and the escape part e is deeper than the stop d. Proceed from the stop portion d to the escape portion e and stop at the escape portion e.
Then, since the lid 8 can no longer be pushed in, when the force pushing the lid 8 is released, the piston portion 41
The trace shaft 44 is pushed out by the restoring force of the lower urging spring 6 compressed in the inside 16, and at this time, the trace shaft 44 reaches the introduction groove a from the escape portion e of the cam groove 9 through the return path f. At this time, since the braked air is sucked into the lower cylinder 16 from the orifice 59, a braking force is applied during the extension process of the piston portion 41, and the piston rod 39 advances slowly and quietly. As the piston rod 39 advances, the lid 8 is gradually pushed out from the opening 3 of the housing 4 via the joint 64, and at the same time, the lower slide holder 7
Are supported, the lid 8 and the lower slide holder 7 integrally and quietly advance. With this advance, the lid 8 is opened while falling forward by its own weight with the shaft 37 of the lower slide holder 7 as a fulcrum (FIG. 5). Then, the lid 8 is opened to the horizontal position, and stops at a position where the lower step surface 73 of the lower end inner surface is in contact with the bottom surface of the lower slide holder 7, and the inner surface of the lid 8 and the lower slide holder 7 are placed. The upper surface of the part 34 is almost flush (FIGS. 3, 6, and 7). When lid 8 opens,
Since the piston 8 is connected to the piston rod 39 via the joint 64, a braking force is applied, and the lid 8 opens quietly. On the other hand, in the lower slide holder 7, the front edge 74 rising from the central cylindrical portion 33 on both inner sides of both mounting portions 34 is formed by a concave chamber of the housing 4.
13 on the rear surface, and the rising end surfaces 75, 7 on both outer sides of both
5 stops at the most advanced position where it comes into contact with the stepped portions 76, 76 formed on both inner side surfaces of the housing 4 (FIG. 7, FIG. 9, left half). When the lid 8 is opened in this manner, the cassette cases 2 are loaded into the slide holders 7 and 12 through the opening 3 of the housing 4, and a total of four cassette cases 2
Can be loaded (Figs. 3 and 7). First, in order to insert the cassette case 2 into the upper stage of the housing 4, the cassette case 2 may be pushed along the upper surface of the middle partition plate 11. As a result, since the upper surface of the middle partition plate 11 and the upper surface of the mounting portion 27 of the upper slide holder 12 are almost flush, the rear end of the cassette case 2 is
27, and stops at a position where its rear surface hits the front surface of the rear wall of the mounting portion 27 (FIG. 7). In order to insert the cassette case 2 into the lower part of the housing 4, the inner surface of the lid 8 is almost flush with the upper surface of the mounting portion 34 of the lower slide holder 7. It only has to be pushed inward while sliding the upper surface, and the entire lower surface of the cassette case 2 is placed on the mounting portion 34,
The trailing surface stops at a position where the rear surface hits the front surface of the rear wall of the mounting portion 34 (FIG. 7). In the loaded state of the cassette case 2, since the rear wall of the mounting portion 34 of the lower slide holder 7 is advanced from the rear wall of the mounting portion 27 of the upper slide holder 12, The tip protrudes stepwise from the opening 3 of the housing 4 (FIGS. 3 and 7). That is, also in the upper slide holder 12, the front edge of the central frame portion 25 is formed on the rear surface of the concave chamber 13 of the housing 4, and the front edges on both sides of the mounting portions 27 are formed on the step portions 76 formed on both inner side surfaces of the housing 4. The same as the lower slide holder 7 in that it stops at the abutted positions, however, by increasing the distance from the stop position to the rear walls of both mounting portions 27, the cassette loaded in the upper slide holder 12 Since the case 2 is retracted one step deeper than the cassette case 2 loaded in the lower slide holder 7, the cassette case 2 protrudes stepwise. Next, in order to close the lid 8, the lid 8 may be pushed in while being pulled up by hand. When the lid 8 is closed and pushed in this way, the piston rod 39 is pushed back through the joint 64, and its piston portion
41 is the lower cylinder against the urging force of the lower urging spring 6.
Pushed into 16. In the process of shortening the piston portion 41,
The O-ring 57 fitted in the annular groove 56 is the lower cylinder
While receiving the friction with the inner peripheral surface of 16, it is held in the annular groove 56 and retreats. For this reason, the air in the piston portion 41 is exhausted from the exhaust groove 58 of the annular groove 56, and the braking force does not work. Therefore, when closing and pushing the lid 8, no extra force is required. The position of the cam groove 9 changes with the retreat of the piston rod 39, and the trace shaft 44 of the lock pin 10
Since the return path f is one step higher than the introduction groove a, the return path f cannot return to the return path f, but proceeds to the forward path b, enters the terminal end c from the shallow end b 'of the forward path b, and stops. Therefore, the lid 8 can no longer be pushed in, and this position is determined so that the lid 8 slightly goes beyond the closed position. When the force for pushing the lid 8 is released, the piston portion 41 is compressed in the lower cylinder 16. The lid 8 is pushed out by the restoring force of the lower urging spring 6 and the lid 8 is slightly pushed back while the lid 8 is standing upright.
Moves backward in the terminal end portion c of the cam groove 9. Since the forward path b is one step shallower than the terminal end c, the trace shaft 44 cannot return to the forward path b, drops into the stop part d adjacent to the terminal part c and becomes one step deeper, and the restoring force of the lower urging spring 6. At the upper end 42 ″ of the heart island 42, and the lid 8
It stops in an upright state facing the opening 3 of the housing 4 (FIG. 12). On the other hand, when the lid 8 is pushed in, the lower slide holder 7 is pushed by the lid 8 and retreats while the cassette case 2 is placed on the upper surfaces of both placing portions 34. When the lid 8 is in the closed position, the pressure button 18 protrudes from the button holes 38 on the rear surfaces of both the mounting portions 34 and elastically presses the rear surface of the cassette case 2 in the mounting portion 34 forward. By doing so, the front surface of the cassette case 2 elastically contacts the inner surface of the lid 8,
Prevent back and forth play of the cassette case 2 (fifth
Figure). On the other hand, the upper slide holder 12 retreats when the front surface of the loaded cassette case 2 is directly pushed by the inner side surface of the lid 8, and the piston portion 26 thereof receives the urging force of the upper urging spring 5. It is pushed into the upper cylinder 15 against it. In the shortening step of the piston portion 26, the O-ring 29 fitted in the annular groove 28 is held in the annular groove 28 and retreated while receiving friction with the inner peripheral surface of the upper cylinder 15. For this reason, the air in the piston portion 26 is exhausted from the exhaust groove 30 of the annular groove 28, and the braking force does not work, so that no extra force is required when the lid 8 is pushed. In the closed position of the lid 8, the restoring force of the upper biasing spring 5 exerts a force to push back the piston portion 26, but the front surface of the cassette case 2 abuts against the inner side surface of the lid 8, By resisting the force and simultaneously pressing the front surface of the cassette case 2 aggressively against the inner surface of the lid 8, the back and forth play of the cassette case 2 is prevented (FIG. 5). The backlash of the lid 8 is prevented by the vibration isolator. That is, as shown in FIG. 16, the pressing body 69 elastically faces from the inside to the lower inner surface of the lid 8 in the upright state.
Is prevented from directly hitting the front edge of the opening 3 of the housing 4. This is when the lid 8 is closed.
It is necessary to push the closed position a little too far,
A small gap is formed between the inner surface of the lid 8 and the front edge of the opening 3 of the housing 4. For this reason, since there is room for the lid 8 to rattle between the gaps, the pressing body 69 is elastically brought into contact with the lid 8 so that the inner surface of the lid 8 is
Of the opening 3 is prevented from rattling. On the other hand, at the time of a vehicle collision or the like, the safety device operates to prevent the lid 8 from opening. That is, the inertia force acts on the weight 49 due to the impact at the time of the collision of the vehicle, and when the inertia force exceeds a predetermined value (for example, 30 G), the weight 49 moves forward against the urging force of the coil spring 50, and 52 faces the trace shaft 44 of the lock pin 10 stopped in the stop portion d of the cam groove 9 from the side, and the lock pin 10 swings in the release direction, that is, the trace shaft 44
From the stop part d to the escape part e (No. 14).
Figure). Therefore, even when the lid 8 is pushed to a position beyond the closed position by the inertial force, the trace shaft 44 is not moved.
Cannot move in the cam groove 9, the locked state is maintained, and the lid 8 does not open. Therefore, even if the occupant strikes the head against the lid 8 at the time of a collision, the lid is closed, so that the safety is higher. Note that the safety device does not operate when the inertial force is less than the predetermined value. Therefore, the lid 8 can be freely opened during normal acceleration or deceleration. On the other hand, when the cassette case 2 is not loaded in the slide holders 7 and 12 and the lid 8 is locked in the closed position in an empty state, the upper slide holder 12
As shown in the figure, it stops at the most advanced position. At this time, since the upper slide holder 12 is pressed to the most advanced position by the urging force of the upper urging spring 5, even when external vibration is applied, the upper slide holder 12 itself may rattle in the housing 4. Absent. Further, even if the cassette case 2 is empty, the lower slide holder 7 retreats integrally with the lid 8, so that the lower slide holder 7 is at the retreat position as shown in FIG. In this retracted position, the pressure button 18
The lower slide holder 7 itself is pressed forward by the flange portion 20 of the lower end, and the slide holder 7 is prevented from moving backward in the housing 4 and rattling. On the other hand, when removing the cassette case 2, the lid 8, which is slightly separated from the opening 3 of the housing 4 and stands upright, may be slightly pushed by hand in the above-described procedure. As a result, the lid 8 falls forward and opens while moving forward, and the leading end of the cassette case 2 projects upward and downward from the opening 3 of the housing 4 in a stepwise manner. Can be taken (Fig. 3).
Further, it is possible to easily load the cassette case 2 into a vacant portion. In the embodiment shown in the drawings, for example, the cassette case 2, the lower slide holder 7, the lid 8
As an example, the projecting body may be any one of the cassette case 2, the lower slide holder 7, and the lid 8. For example, if the cassette case 2 is directly stored in the housing 4, the slide holder and the lid may be omitted. Further, in the case of a storage device other than the cassette case, for example, a glove box, another accessory case, an ashtray, or the like, the lid or the inner case is mainly protruded, and the glove box, accessory case, ashtray, etc. To prevent it from protruding or sliding forward. Further, the biasing springs 5 and 6 have been described as the biasing means of the cassette case 2, the lower slide holder 7, and the lid 8 as the main body of the projection. However, the cassette case 2 is formed by using a constant pressure spring or a tension spring. , The lower slide holder 7, the lid 8, and the like may be urged in a direction to protrude forward from the opening of the housing 4. On the other hand, the lock means is not limited to the combination of the cam groove 9 and the lock pin 10, but may use a rotating cam. In addition, the safety device also allows the weight 49 to move forward by inertial force. In addition, the weight 49 is pivotally supported, and the weight 49 is tilted forward so that the lock pin 10 projects into the movement area. In such a case, the weight 49 may be pulled in the backward tilt direction by a coil spring. <Effects of the Invention> As described above, according to the present invention, at the time of a vehicle collision, the safety device operates to prevent the unlocking operation of the locking means from being released, so that the main body of the projection is the opening of the housing. It is possible to provide a vehicle-mounted storage device that does not protrude forward and is highly safe.

Claims (1)

(57) [Claims] A housing having an opening; a projecting body biased by a biasing means in a direction projecting forward from the opening of the housing; and a projecting body locked at a non-projecting position against the biasing force of the biasing means. And a push-push locking means in which a lock pin traces a cam groove, wherein the lock state can be released when the projecting main body is further pushed into the housing from the non-projecting position. In the storage device for mounting in a vehicle, when an inertial force equal to or more than a predetermined value for pushing the projecting main body into the housing acts on the locking means, a weight is applied against the urging force of the weight urging means by the inertial force. A safety device for displacing and preventing the lock pin from tracing the cam groove to release the locked state with the weight is provided.輛 mounting storage devices.
