DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail on the basis of a preferred embodiment shown in the drawings. The switchgear according to the embodiment is also developed for a grab box that is pivotally supported on a passenger panel of an automobile. However, the feature is that the following configuration is adopted.
[0015]
First, for the passenger panel P as a support structure, as shown in FIG. 1, bearing portions 1 for fitting cylinders 11 of air dampers 10 to be described later are provided on both lower sides thereof, and stopper pins to be described later on both side walls. A pair of guide grooves 2 for guiding the movement of 8 is formed, but each guide groove 2 is formed in a state along the movement locus of the corresponding stopper pin 8. A large working window 3 for replacing the air conditioner filter is formed on the rear wall of the passenger panel P.
[0016]
Further, as shown in the figure, the grab box B which is a box body is provided with bearing portions 4 which cooperate with the bearing portion 1 on both sides of the lower portion thereof, while stopper pins 6 are provided on both side walls corresponding to the respective guide grooves 2. A pair of mounting holes 5 that are rotatably mounted from the inside to the outside are formed, and a guide hole 6 that guides the middle of a string 13 of an air damper 10 described later in the vertical direction of one side wall, and the string 13 The front end portion 13a is detachably engaged with the fixing hole 7 so as to be separated from each other. As shown in FIG. 2, each of the former mounting holes 5 has a hole edge. The guide hole 6 and the fixing hole 7 have a key hole shape having wide hole portions 6a and 7a and narrow hole portions 6b and 7b. It has become.
[0017]
The stopper pin 8 inserted into each mounting hole 5 is composed of a cylindrical portion 8a and an enlarged head portion 8b, and has a configuration that forms a pair of locking pieces 9 that face the root side of the cylindrical portion 8a. The pair of locking pieces 9 formed on the cylindrical portion 8a of the stopper pin 8 is inserted into the mounting hole 5 as it is while matching the large-diameter portion 5a of the corresponding mounting hole 5, and the enlarged head 8b is picked. If it rotates 90 degrees, the stopper pin 8 will be rotatably attached to the attachment hole 5. If the stopper pin 8 is further rotated by 90 °, it can be pulled out from the mounting hole 5.
[0018]
Next, as shown in FIG. 3, the string-type air damper 10 is fitted to the one bearing portion 1 on the passenger panel P side and the one bearing portion 4 on the grab box B side, and serves as a hinge pin. A cylindrical cylinder 11, a piston 12 connected to the base end of the string 13 and moving in the cylinder 11, a guide cap 14 for guiding the movement of the string 13 on one end opening side of the cylinder 11, An end cap 17 with a valve 16 that opens and closes the communication hole 15 formed in the other end opening, and a compression coil spring 18 that is interposed between the guide cap 14 and the piston 12 in the cylinder 11 are provided.
[0019]
The leading end 13a of the string 13 is usually drawn out from the guide cap 14 and passes through an appropriate via 20 to enter the wide hole 6a in the guide hole 6 located above the grab box B. After being guided through the inner surface of the grab box B, it is detachably engaged with the narrow hole portion 7b of the fixing hole 7 located below via a ring stopper 19 provided at the tip portion 13a. However, the distal end portion 13 a of the string 13 is configured to be able to detachably engage with the guide hole 6 by releasing the engagement with the fixing hole 7. Further, the engagement state of the distal end portion 13a of the string 13 with respect to the guide hole 6 and the fixed hole 7 is ensured by the engagement of the ring stopper 19 with the narrow holes 6b and 7b defining the keyhole shape. Will be.
[0020]
Therefore, in the opening / closing device having such a configuration, when assembling the grab box B on the passenger panel P side, first, the string 13 of the air damper 10 is inserted into the guide hole 6 through the wide hole portion 6a. The cylinder 11 of the air damper 10 is fitted into each of the one bearing portions 1 and 4 while the leading end portion 13a of the string 13 is engaged with the narrow hole portion 7b of the fixing hole 7 via the ring stopper 19. At the same time, a hinge cylinder (not shown) similar to the cylinder 11 is fitted into each of the other bearing portions 1 and 4, and the grab box B is pivotally supported on the passenger panel P so that each mounting hole is mounted. When the left and right stopper pins 8 are inserted into 5 from the inside and rotated 90 °, as shown in FIG. 4, each stopper pin 8 is rotatably mounted in the mounting hole 5 and at the same time, the tip of the cylindrical portion 8a of the stopper pin 8 Passe So that the face jar panel P of the guide groove 2.
[0021]
Accordingly, in this assembled state, when the grab box B is moved in the opening direction, the string 13 is gradually pulled out from the cylinder 11 and the piston 12 moves in the same direction against the spring pressure of the compression coil spring 18. Therefore, it is ensured that the grab box B slowly moves to the open state by the flow resistance of the air passing through the orifice (not shown) opened on the piston 12 side, and accordingly, As shown in FIG. 5, since the left and right stopper pins 8 come into contact with the front end edge of the guide groove 2, the full open position of the grab box B in a normal state is thereby restricted.
[0022]
Conversely, when the grab box B is moved in the closing direction, the piston 12 is forcibly pushed back into the cylinder 11 by the spring pressure of the compression coil spring 18 together with the string 13, and into the cylinder 11. Since the accumulated air is released from the end cap 17 side to the outside through the communication hole 15 opened by the valve 16, the piston 12 moves quickly in the cylinder 11, and the closing operation of the grab box B is facilitated. However, in such a state, the left and right stopper pins 8 move in the reverse direction in the guide groove 2 and return to the original position.
[0023]
Under such an opening / closing device, for example, when replacing an air conditioner filter (not shown) arranged behind the passenger panel P, first, the left and right stopper pins 8 are first rotated by 90 °. After pulling out from the mounting hole 5 and completely solving the relationship between the passenger panel P and the grab box B, this time, it is engaged with the fixing hole 7 located below the grab box B as shown in FIG. If the front end portion 13a of the string 13 of the air damper 10 is removed and engaged with the guide hole 6 positioned above, the string 13 is substantially as long as it exists in the grab box B. Accordingly, as shown in FIG. 7, the grab box B is rotated downward through the shaft support portion as shown in FIG. 7 so that the interior of the passenger panel P is opened. Since it down, this way, by using a large working window 3 of the passenger panel P, it is possible to easily replace the air conditioning filter disposed in the rear.
[0024]
After the replacement of the air conditioner filter, the grab box B is rotated upward, and the tip 13a of the string 13 is transferred again from the guide hole 6 to the fixing hole 7 to be engaged. When the stopper pin 8 is inserted into the mounting hole 5 and rotated by 90 °, the tip end portion 13a of each stopper pin 8 again faces the corresponding guide groove 2, so that normal opening and closing can be used. It becomes.
[0025]
Moreover, under the present embodiment, the work can be performed from the inside of the grab box B both when the tip 13a of the string 13 is engaged with the guide hole 6 and when it is engaged with the fixing hole 7. Needless to say, the cord 13 can be provided with a margin by the distance between the guide hole 6 and the fixing hole 7, particularly when the tip 13 a of the cord 13 is engaged with the guide hole 6. However, it can also prevent that the front-end | tip part 13a of the string 13 is drawn in the inside of the cylinder 11. FIG. If the length of the string 13 is sufficiently long, the string 13 will not be pulled into the cylinder 11 without engaging the tip 13 a of the string 13 with the guide hole 6.
[0026]
