Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a safety device for preventing an automobile door stored in a cage of a multi-storey car park from opening during movement of the cage and damaging the automobile or the parking device. More particularly, the present invention relates to improvement of a door protection fence drive device.

[Conventional technology]

Conventionally, in this type of device, a door protection fence is installed at the position of a car door stored in a cage, and the door protection fence can be opened and closed, so that the car stops at the bottom for the car to enter and exit. It is configured so as not to interfere with getting on and off the driver's car at that time, and to prevent the door of the stored car from opening when driving the cage. The cage is placed on the turning device in the pit at the bottom of the cage, and the positional relationship with the turning device is detected by the cage detection device, and if there is a deviation, it is properly adjusted.

A drive device for opening and closing the door protection fence is required, but this drive device is placed separately from the cage and is usually provided outside the pit.

[Problems to be solved by the device]

As mentioned above, the conventional door guard fence drive is installed outside the pit, so if the cage stops at the bottom, if there is a misalignment with the dynamic guard fence, the door guard fence is activated. In some cases, it may not be possible to do so.

In view of such circumstances, the present invention makes it possible to operate the door protection fence regardless of the deviation between the position of the cage and the position of the door protection fence drive device when stopped at the bottom. The purpose is to

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention installs a door protection fence drive device in a turning device in a pit, and guides the guide rod provided along the direction of driving the door protection fence. And a drive cylinder for sliding the cam follower, the cam follower having an inner cylinder slidable in the axial direction and an outer cylinder axially fixed to the inner cylinder and slidable in the circumferential direction. A cam groove plate formed of a cylindrical member provided in parallel with the guide rod and having an inner circumferential arc surface engraved with a circumferential curved groove and an axial straight groove continuous with the curved groove; and an outer side of the cam follower. A member that is provided on the cylinder and that engages with the groove of the cam groove plate and a member that is provided on the outer cylinder of the cam follower, is rotated by sliding of the cam follower, and then linearly moves in the axial direction to stand up from a horizontal state to protect the door. Open and close the fence It is characterized in that is constituted by the pressing lever.

[Action]

Since the positional relationship between the cage stopped at the bottom and the turning device in the pit is adjusted properly beforehand, slide the cam follower with the drive cylinder of the door guard fence drive device installed in the turning device. By
The presser lever opens and closes the door protection fence.

〔Example〕

A description will be given based on FIGS. 1 to 7. Reference numeral 1 is a door protection fence for preventing the opening of the door of the car housed in the cage 2, and is attached to both sides of the floor of the cage 2.

The door protection fence 1 is composed of two legs and a cross girder bridged between the legs, the lower ends of the legs are pivotally attached to the floor side of the cage 2 by pins 14, while the upper ends of the legs are on the cage floor. A link mechanism is pivotally attached to both ends of the cross beam parallel to the plane.

The lower end of one of the legs is extended further downward, and the extended end is pivotally connected to one end of a push rod 13 attached to the side of the cage so as to be movable in the axial direction parallel to the cage floor. It is worn. The push rod 13 is slidable in the direction of the arrow in FIG. 7 and is constantly biased by the spring 15 in the direction opposite to the arrow. Therefore, unless an external force in the direction of the arrow acts on the push rod 13, the door protection fence. 1
The legs are upright, and the door protection fence 1 maintains the closed state.

The drive device 3 for opening and closing the door protection fence 1 is attached to a turning device 4 for turning a turntable provided for turning over the car stored in the cage 2 in the pit at the bottom of the multilevel parking device. ing.

The drive device 3 is fixed on a base plate fixed to the uppermost outermost surface of the swivel device 4, and is composed of a cylindrical member that leaves approximately 1/2 of its circumference in a cross section perpendicular to the axis. A cam groove plate 5 in which a curved groove 11 in the circumferential direction and a linear groove 12 in the axial direction continuous with the curved groove 11 are engraved on an inner circular arc surface.
A guide rod 9 installed on the base plate in parallel with the inner circumferential arc surface of the cam groove plate 5 at a predetermined interval, and a power cylinder arranged on the base plate in parallel with the guide rod 9. 7, an inner cylinder slidably supported by the guide rod 9 and having an end connected to the rod of the power cylinder 7 via a connecting rod 16, and a slidable mount in the circumferential direction and an outer periphery thereof. Engaging member 10 that engages with the grooves 11 and 12 of the cam groove plate
The cam follower 6 is composed of an outer cylinder provided with a press lever 8 and a presser lever 8 fixed to the outer cylinder of the cam follower.

The inner cylinder and the outer cylinder of the cam follower 6 are slidable in the circumferential direction as described above, but have a structure in which they cannot relatively move in the axial direction.

Next, the operation of the door protection fence drive device of the multi-storey parking lot having the above-described configuration will be described.

First, when the cage 2 descends and stops at the bottom, a cage detection device (not shown) provided in the swivel device 4 detects the position of the cage 2 with respect to the swivel device 4, and confirms that the cage 2 is at a predetermined position. After the detection, the power cylinder 7 of the door protection fence drive device 3 operates to pull the rod toward the solid arrow in FIG. When the rod is pulled, the cam follower 6 slides on the guide rod 9, but at this time, the engaging member 10 moves along the curved groove 11 and the straight groove 12 formed in the cam groove plate 5, so that the cam follower 6 moves. 6
The outer cylinder makes a rotary motion and then a linear motion, and the presser lever 8 attached to the outer cylinder stands up from the horizontal state and push rod 13
Open the door protection fence 1 via.

Contrary to the above, when the power cylinder is operated in the direction of the chain line arrow in FIG. 4, the pressing lever 8 retracts and the spring 15 causes the door protection fence 1 to return to the closed state.

[Effect of device]

The present invention is a multi-level parking apparatus of a type in which the position of the cage to be landed and the turning device are adjusted in advance by providing a door protection fence drive device in the turning device in the bit.
Since the positional relationship between the presser lever and the door protection fence is always maintained properly, the door protection fence operates correctly even if the cage stop position varies.

Further, since the presser lever is made to operate by the configuration of the cam groove plate and the cam follower, the movement locus of the presser lever can be accurately obtained with a simple structure, and the presser lever can be accurately engaged with the push rod. It is possible to ensure the operation of the door protection fence.
