Description

[Detailed Description of the Invention] The present invention relates to a safety device in a mechanical parking device that prevents the rear door of a light van or the like from being opened upon impact during driving.

Currently, in mechanical parking systems such as vertical circulation type, multilayer circulation type, horizontal circulation type, etc., most accidents that occur while driving are due to forgetting to close the door of the stored car. A safety device that prevents the impact opening of the side door has already been disclosed in Patent No. 797861 owned by the applicant.
No. (1978-14429) and No. 797862 (No. 50-14429)
-14430) and has been implemented.

However, at present, there are no safety devices for the rear doors of automobiles such as light vans, and many accidents have occurred, and countermeasures are required.

Therefore, the present invention attempts to provide a safety device for a mechanical parking device that fully satisfies the above requirements. A fence support mechanism, a movable fence rotatably attached to the fence support mechanism for preventing opening of a rear door of an automobile, and a drive mechanism installed on a tray landing surface for rotating the movable fence, The mechanism consists of upper and lower bearing sleeves connected by a web plate and a coil spring for reversing the fence provided between these sleeves. It consists of an upright rod having a rotary lever that is supported by a bearing and branches downward, a horizontal bending rod that is continuous with the rod and bent inward, and a hanging rod that is formed so as to straddle the rear door. The mechanism consists of a geared motor and a drive arm for rotating the rotary lever, which has a drive roller at the tip and is fixed to the output shaft of the reducer. Even if the car on the tray receives an impact while driving, the movable fence will be in its active position, that is, in a position perpendicular to the direction in which the car enters and exits, and will be in a state where it straddles the rear door, preventing the rear door from opening. Since the movable fence is in an inactive position, that is, a position parallel to and perpendicular to the direction in which the vehicle enters and exits, and does not obstruct the entry and exit of the vehicle, it does not pose any obstacle when getting on and off the vehicle, and can be easily installed in an existing parking device. Furthermore, since the structure is simple, it is easy to manufacture and inexpensive.

Next, the present invention will be explained in more detail with reference to an embodiment shown in FIGS. 1 to 3.

FIGS. 1 and 2 show an entrance 2 and a tray elevator room 3 through which a vehicle 1 such as a light van is entered and exited, for example, in an underground horizontal or multi-layer circulation parking system.
3, a movable fence 6 is provided on one side edge of the tray 4 on which the automobile is placed, for example, the left side edge 5 in FIG. It is in a vertical position (solid line position in FIGS. 1 and 3) and is in a state where it straddles the rear door 7 of the vehicle, and in an inactive position it is in a vertical position parallel to the direction of vehicle entry and exit (as shown by the two-dot chain line in FIG. 1). In this case, the movable fence is attached to an upright rod 8 rotatably mounted on the left side edge 5 of the tray 4. , a horizontal bending rod 9 bent inward formed continuously with the rod, and a hanging rod 10 processed so as to straddle the rear door 7, and a hanging rod 10 branched below the upright rod. The rotation lever 11 is connected to the tray landing surface 12
It is designed to work in conjunction with a drive mechanism 13 installed at.

Further, as shown in FIGS. 4 and 5, the drive mechanism 13 mainly includes a geared motor 14, a drive arm 16 fixed to a reducer output shaft 15, and a drive roller 17 attached to the tip of the drive arm 16. an upright rod 8 forming a movable fence 6;
The lower part thereof is rotatably supported by a lower bearing sleeve 19 and a flanged upper bearing sleeve 20 of the fence support mechanism 18, and the lower bearing sleeve is supported by a support plate 21 mounted on the tray side edge 5. The upper bearing sleeve is installed upright and has a notch 22 at its upper end, and both sleeves are integrally formed with a web plate 23, and the fence is wound around below the upright rod 8 of the movable fence 6. The upper end 25 of the coil spring 24 is hooked to the flange 26 of the upper bearing sleeve, and the lower end 27 is hooked to the base 28 of the rotating lever 11.

The upper part of the coil spring 24 is regulated in position by a stopper 29 fixed to the upright rod 8, and the lower part is regulated in position by a mounting disk 30, which is integral with the rotary lever 11 and is similar to the previous one.

To explain the operating mode of the device of the present invention having the above-mentioned configuration, when a certain tray 4 is driven to a predetermined car loading/unloading position and stopped in order to store a car 1, a stop confirmation switch or the like is activated. The geared motor 14 of the drive mechanism 13, which is linked to the garage operation, is driven through an appropriate switch means (not shown) to move the drive arm 16 in the counterclockwise direction from the solid line position shown in FIG. 5 to the two-dot chain line position. When the rotary lever 11 is rotated to the position shown in FIG. It is rotated in the direction of the hour hand from the solid line position to the two-dot chain line position in FIG. 1 against the spring force of the spring 24, and by stopping the drive mechanism 13 at this position, it does not interfere with the vehicle's entry. state.

Next, when the car 1 is stored on the tray 4, the drive mechanism 13 is reversely driven, and in FIG. The coil spring 2 was moved and was compressed accordingly.
4 is reversed by the restoring force, the movable fence 6 returns from the two-dot chain line position to the solid line position in FIG.
0 is the rear door 7 of the automobile 1 as shown in FIG.
The door is in a state of being prevented from opening as if straddling the door, which is safe because it is possible to prevent an accident caused by the door being left ajar during subsequent garage operation.

In the above embodiment, a geared motor, a drive arm, etc. are used as the drive device, but it goes without saying that a ball screw or the like may be used instead to achieve the same purpose.
