DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vehicle restraint system for locking a vehicle body in an unmanned parking lot according to an embodiment of the present invention will be described with reference to FIGS. The box 1 has a built-in drive mechanism for moving the flap plate 5 from the prone position to an obliquely upright position smaller than 90 ° during parking. This drive mechanism is composed of a pair of levers 10, each of which has a tip connected to an arm-shaped rib 5 a provided on the back surface of the flap plate 5 by a connecting rod 11 and pivoted by a pin 11 a, and a base of the ribs 5 a on both sides. A shaft 13 rotatably inserted into the insertion hole 5b at the end and slidably guided by long grooves 26a at both ends of the guide portion 26 attached to the side wall of the box 1 at the end; A pair of block-shaped stoppers 20 are rotatably inserted into each other and connected to each other by a connecting rod 22, and an air cylinder 18 for driving a cylinder rod 19 whose front end is fixed to a base plate 21 to advance and retreat. .

The pin 11a of the lever 10 is
Occupies an intermediate position in the height direction, and its base end is pivotally connected to a shaft support 15 provided on the box bottom surface 1a by a pin 15a. The pin position is such that the pin 11a is supported in a state where the flap plate 5 is tilted in the retreating direction in the standing position.
It occupies a position ahead of the position. At the intermediate position of the lever 10, a stopper 20 that has been advanced in conjunction with the forward slide of the proximal end of the rib 5 a, that is, the proximal end of the flap plate 5.
An engagement portion 12 cut at, for example, a right angle is formed so as to be engaged with the edge at the upright position to restrict downward rotation.

The operation of the thus constructed vehicle restraining device will be described below in connection with the case where the vehicle restraining device is installed below the center of the vehicle in the vehicle width direction. In the normal state, the flap plate 5 is moved by the cylinder rod 19 occupying the retracted position (see FIG. 2).
In FIG. 1, it occupies a prone position indicated by a dashed line along the upper surface of the box 1. When it is detected that the vehicle has entered the parking position, the cylinder rod 19 is driven forward while sliding the shaft 13 via the stopper 20 along the long groove 26 a of the guide portion 26. As a result, the base end of the flap plate 5 moves forward in the horizontal direction along the box bottom surface 1a along the parking surface, and at the same time, the lever 10 is rotated upward to gradually stand up, and the stopper 20 is also interlocked with the cylinder. The robot advances in the horizontal direction while being supported by the rod 19 and the shaft 13.

At the final forward position of the cylinder rod 19, as shown in FIGS. 1 and 3, the flap plate 5 reaches a normal standing position. At this time, the edge 23 of the tip end of the stopper 20 that has moved forward in conjunction with the engagement with the engagement portion 12 of the lever 10 (see FIG. 4). If the vehicle bottom rides on the flap plate 5 while the vehicle tries to escape in the reverse direction while the flap plate 5 is standing up in this way, a backward load is applied to the cylinder rod 19 via the shaft 13, but they are linked. The downward rotation of the lever 10 causes the stopper 20 to rotate.
In other words, the horizontal surface of the engaging portion 12 abuts on the horizontal upper surface of the stopper 20 so that the component force in the retreating direction hardly acts, thereby preventing the retreat load from being applied to the cylinder rod 19.
On the other hand, when the lower end portion of the flap plate 5 is pushed to further rise in the 90 ° direction, the base end portion of the flap plate 5 is restrained by a stopper (not shown) provided on the box bottom surface 1a.

In the erecting operation of the flap plate 5, the distal end thereof rises substantially vertically as the proximal end moves forward as shown in FIG. 5, and the proximal end pivots. The moving range of the normal flap plate in the reciprocating direction can be suppressed with respect to the arcuate moving path of the normal flap plate, and it is possible to prevent the flap plate from being stuck on the vehicle body particularly when returning from the standing position to the prone position.

It is to be noted that, by such an arrangement at the center position in the vehicle width direction, movement of a vehicle portion such as an oil pan and a muffler can be restrained, and unauthorized operation becomes difficult. And the tires may be locked by being arranged on the traveling route of the vehicle.

FIG. 6 shows a double-flap type vehicle restraining device in which the operation state can be viewed from the side even when the flap plate 5 is arranged at the center position by adding a structure to the above-described vehicle restraining device. The same or equivalent parts as those described above will be described with the same reference numerals. The width of the box 1 shown in FIG. 1 is enlarged, and the end of a shaft extension 13a obtained by extending the shaft 13 is rotatably supported on the side wall thereof. A shaft extension 13a is rotatably inserted into the base end of the arm-like rib 28 attached to the back surface of the auxiliary flap plate 6. The side end 6a of the auxiliary flap plate 6 is overlapped on the back surface of the side end of the adjacent flap plate 5, and is urged toward the upright position by a spring 27 mounted on the shaft extension 13a.

When the flap plate 5 moves to the normal standing position as the cylinder rod 19 advances, the auxiliary flap plate 6 rotates to the standing position in conjunction with the spring force. Due to the presence of the auxiliary flap plate 6, the undulation state of the flap plate 5 can be checked from the outside, and even if the lateral auxiliary flap plate 6 is intentionally pushed down, it only rotates independently, and the restraining operation of the flap plate 5 is performed. Is not disturbed. Even when the side of the vehicle body is at a low position, the auxiliary flap plate 6 only needs to abut on the spring force.

The side end 6a of the auxiliary flap plate 6 may be restrained in a state of being juxtaposed in the same plane by a stopper provided on the surface of the side end of the flap plate 5. The base end may be supported by the shaft extension 13a via a bearing.

FIG. 7 shows a modification of the vehicle restraining device shown in FIG. 6, in which an air cylinder 18 whose front and rear position is inverted is disposed below the flap plate 5, and the tip of a cylinder rod 19 is attached to the shaft 13 described above. It is rotatably supported, and the flap plate 5 stands up by the retraction of the cylinder rod.
When the stopper 20 is used as described above, the connecting rod 2
By connecting and driving the cylinder rod 19 which has been inverted to the front and rear, the downward rotation of the lever 10 can also be restrained.

FIGS. 8 to 10 show a vehicle restraining device for blocking a retreating path, and have a barrier flap plate 40 having a height higher than the bumper position and which can be confirmed from the vehicle interior. The air cylinder 30 is housed in the box 39, and the base end of the cylinder 35 is hinged to the box 39.

A pair of levers 44 is provided at the tip of an arm-shaped rib 41 provided in a lower area on the back surface of the flap plate 40.
Connecting rods 45 for connecting the tips of
It is pivotally attached at a. A connecting rod 42 is inserted into the base end of the rib 41, and both ends 42 a of which the diameter is reduced are slidably guided by a long groove 43 a of a guide part 43 attached to a side wall of the box 39 as a slide pin. Have been. The proximal end of the lever 44 is pivotally connected to the distal end of the cylinder 35 of the air cylinder 30 with a pin 47. As shown in FIG. 9, the distal end of the cylinder rod 32 is pivotally connected to the distal end of a U-shaped swing lever 33 rotatably supported by a connecting rod 42 by a pin 33a.

On the upper surface of the box 39, as shown in FIG. 10B, there is formed an opening 39a for allowing the lever 44 to protrude and retract, and a recess 39b of a corresponding shape for accommodating the flap plate 40 is formed ahead of the opening 39a. The height is set to the thickness of the flap plate 40.

The box 39 is buried with concrete around the front of the exit path so that the flap plate 40 stands up to an angle slightly smaller than 90 ° facing the parked vehicle, and is buried flush with the ground. Be included. The flap plate 40
In the normal state, since the cylinder rod 32 occupies the forward position, the cylinder rod 32 is housed in the recess 39b on the same plane, and
Occupies the prone position shown in the figure. In this state, Box 3
Even when buried in the snow, the surface 9 is flush with the ground, so that it does not interfere with the snow-plowing tool when performing snow-plowing.

4 is rotated upward to gradually stand up. At this time, the flap plate 40 rises substantially vertically upward, and rises to the position shown in FIG. 10B without interfering with the leading edge of the concave portion 39b.

The base end of the air cylinder 30 is hinged to the flap plate 40, and is driven through the swing lever 33, so that the flap plate 40 is driven smoothly with some mounting errors and the like allowed. However, in some cases, the distal end of the cylinder rod 32 may be directly rotatably supported by the connecting rod 42. The proximal end of lever 44 may be pivotally attached to the side wall of box 39.

Incidentally, the flap plate 40 can be made wider together with the entire apparatus in order to prevent the flap plate 40 from slipping out from the side and leaving the vehicle. Further, instead of the barrier flap plate, it may be formed in a horizontally long shape to be used for locking the vehicle body that restrains the vehicle bottom or the front bumper or the rear bumper.

Although all of the above embodiments have been described using an air cylinder, the present invention can be applied to a hydraulic cylinder.

[0027]

According to the first aspect of the present invention, since the flap plate is driven in a crank manner, the tip of the flap plate moves vertically or almost vertically upward, particularly when returning from the standing position to the prone position. It is possible to suppress interference such as not returning while being caught.

According to the second aspect of the invention, when the flap plate is driven by the cylinder, even if the vehicle rides on the flap plate and a load is applied from above, the descent is prevented from lowering. And damage to the accessory parts due to the forward / backward load on the cylinder rod is also avoided.

According to the third aspect of the present invention, the overall length of the apparatus can be suppressed even when the height of the flap plate is increased for use as a barrier.

According to the fourth aspect of the present invention, even when the flap plate is arranged at the center portion in the vehicle width direction to make it difficult to perform an unauthorized operation, the operation state of the flap plate can be confirmed by the auxiliary flap plate. Is improperly operated, the restraining operation of the flap plate is not affected. By being biased by the spring, it is only necessary to abut on the side of the vehicle body at a low position without restraining it by the spring force.
