DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parked vehicle exit prevention device useful in an unmanned parking lot such as a coin-type parking lot.

[0002]

2. Description of the Related Art FIG. 1 is a plan view of a conventional device for preventing a parking vehicle from leaving, FIG. 2A is a cross-sectional view taken along line CC of FIG.
FIG. 2B is a front view illustrating a state in which the leaving device of the parked vehicle operates. In each of the drawings, reference numeral 2 denotes a lock portion, 4 denotes a drive mechanism portion, 6 denotes a parked vehicle, 8 denotes an obstacle such as a curb, 10 denotes a road surface, and the device for preventing the parked vehicle from leaving is a lock portion 2 and a drive mechanism portion. And 4. Thus, the lock part 2 has one end connected to the drive mechanism part 2 by the coupling 22, the support parts 16 a and 16 b supporting the rotary shaft 12 at both ends, and stands about the rotary shaft 12. Or, it is configured to include a lock plate 14 that abuts on the tires or the vehicle body of the parked vehicle 6 in the standing and standing state to prevent the parking vehicle 6 from leaving. The central side 141 of the lock plate 14 has a bend with the outer periphery of the rotating shaft 12 as the inner periphery, and is welded to the circumference of the rotating shaft 12 located inside the support portions 16a and 16b. The distal end side 142 of the lock plate 14 is a free end, forms a slope with respect to the road surface 10 in the fall state, and the distal end side 142 hits the tire of the parked vehicle 6 in the upright state. The fixed slope plate 18 is the locked lock plate 1 in the lying state.
A slope having the same height as 4 is formed. When the parked vehicle 6 enters the parking area, one wheel gets over the slope plate 18 and the lock plate 14 having the riding height GL. The flat plate 20 is provided to improve installation workability. The drive mechanism 4 receives a lock signal transmitted when a control device (not shown) detects the presence of the parked vehicle 6, rotates the rotary shaft 12, and raises the lock plate 14. Further, upon receiving the lock release signal transmitted when the parking fee is paid, the rotation shaft 12 is rotated in the reverse direction, and the lock plate 14 is brought down. The parking area includes three directions other than the entrance and exit of the parked vehicle 6.
Is closed. For this reason, the parked vehicle exit prevention device raises the lock plate 14 when the parked vehicle 6 enters the parking area, prevents the parked vehicle 6 from leaving, and lowers the lock plate 14 when the parking fee is paid. This allows the parked vehicle 6 to leave.

[0003]

However, the above-described conventional device for preventing the leaving of a parked vehicle has the following problems. (A) When the riding height GL of one wheel is high and the slope is steep, the inexperienced driver gets over the lock plate 14 and blows the engine too much. He could not stop, causing collisions with passers-by and other vehicles. (B) Since the car maker manufactures vehicles of various heights, vehicles having a low vehicle bottom are also parked, and the support portion provided outside the lock plate 14 and having a higher height is provided. 1
An accident has occurred in which the bottom of the vehicle is hooked on the protective cover 6b and the vehicle is damaged. In addition, there is also a problem that the passerby easily trips over the protruding support portion 16b and is likely to be injured. (C) On the other hand, in a four-wheel drive vehicle or the like in which the bottom of the vehicle is raised, the lock plate 14 having a short front end length WL (usually within 20 cm) can easily get over. (D) On the other hand, in the case of the lock plate 14 having a long distal end side length WL, there is a danger that a limb or the like of a human body is sandwiched between the drive mechanism unit 4 and the lock plate 14, and in the worst case, it is cut off. There is also. Regarding the problem A, Japanese Unexamined Utility Model Publication No. 4-94064 discloses a method of reducing a mounting position on a rotating shaft by providing a cutout surface, or removing a rotating shaft inside a support portion to reduce a riding height GL. Examples have been reported. However, in the case of the conventional locking part, for example, in the case of the rotating shaft 12 having a diameter of 30
a, 16b often use bearings, inner diameter 3
The outer diameter of the 0φ bearing is 60φ at minimum, and it is very difficult to reduce the height of the outer supporting portion 16b to 80 mm or less even if the riding height GL can be reduced. To solve the above problem C, Japanese Patent Publication No. 1-54509 discloses the use of a motor and gears to prevent the lock plate from being illegally retreated by a tall vehicle, and to provide a shock absorbing mechanism to prevent overload damage. Techniques to prevent this have been reported. However, for a vehicle having a high vehicle height, it is necessary to increase the width of the lock plate 14 to at least 50 cm if the length in the width direction can be at least 40 cm or more. Because it becomes a very heavy plate of up to 8 times, it is easy to overload the gear at the time of acceleration and deceleration, and the gear tooth is missing or it repeats normal and reverse rotation due to heavy load, so play is likely to occur between the gears, Further, there is another problem that a desired opening / closing speed cannot be obtained unless a large-capacity motor is used for the power source.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a low-height vehicle without contacting the vehicle bottom and all parking spaces. It is easy and quiet to get over even if the vehicle does not blow the engine, and after locking, the tall vehicle does not allow illegally exiting, and it is also gentle and safe for the human body. It is another object of the present invention to provide an efficient and easy-to-maintain exiting device for a parked vehicle, which does not cause rattling or chipping even when a heavy lock plate is opened and closed.

[0005]

SUMMARY OF THE INVENTION The present invention is directed to a locking device for locking a parked vehicle, and a driving mechanism for driving the locking portion to rotate after the parked vehicle enters. The above object of the present invention relates to a device, wherein the lock portion is configured such that one end of the lock portion is connected to the drive mechanism portion, a support portion that supports the rotary shaft at a plurality of locations, and the lock portion stands up about the rotary shaft. Or, in the upright state, includes a lock plate that abuts on the parked vehicle in the upright state to prevent retreat, elastic biasing means for elastically biasing the lock plate in the upright direction, and a fixed slope plate. The drive mechanism includes a linear moving mechanism, and a power transmitting mechanism for transmitting the power of the linear moving mechanism to the rotation shaft of the lock unit, and the drive mechanism is attached to the lock plate in the power transmitting mechanism. Torque detecting means for detecting the torque Torque above a predetermined torque value by the output of the detecting means is achieved by not transmitted to the locking plate from the linear movement mechanism.

The operation of the above configuration will be described below. FIGS. 4 and 5 corresponding to FIG. 3 are diagrams for explaining the principle that the height GL of the lock portion 2 of the present invention can be configured to be very low as 65 mm or less, and FIG. FIG. 4 is an enlarged plan view of the support portion 16 and its peripheral portion.
4B is a plan view and a front view of the oiles 15, FIG. 4C is a cross-sectional view of the lock plate 14 cut at the bearing 17, FIG.
(D) is a cross-sectional view of the locking portion 2 cut at the support portion 16, and FIG. 5 is a perspective view when the locking portion 2 and the drive mechanism 4 are mounted on the flat plate 20. As shown in FIGS. 3 to 5, in the present invention, the support portion 16 of the rotary shaft 12 into which the oil 15 is press-fitted is disposed below the lock plate 14 and / or the fixed slope plate 18. As shown in FIG. 4 (D), each member is formed by using a steel plate having a thickness of t, and the upper and lower margins of the support portion 16 have the same dimensions as the thickness t. When using OILES, the ride height of one wheel is GL = 5t + 30 mm. As an example, when steel material having a thickness of t = 6 mm is used, the ride height of one wheel GL
= Very small locking part 2 of 60 mm can be realized. Also,
The maximum plate width WL on the tip side of the lock plate 14 is 40 cm or more,
Preferably, if the length is 50 cm or more, a vehicle with a high bottom such as a 4WD driven vehicle can be reliably detected, and the plate width WL
Is two to three times as long as the conventional one, the inclination of the lock plate 14 with respect to the ground becomes very gentle, and even an inexperienced driver can easily get over the lock plate 14. In addition, the height of the slope plate 18 can be reduced by decreasing the riding height GL, so that it is not necessary to accelerate the engine even when the vehicle enters. Further, since the support portions 16a, 16b, etc., which were conventionally provided outside the lock plate as a matter of course, are all disposed below the lock plate, etc., a pedestrian trips on the support portion 16b and is injured. There is an advantage that no accidents such as damage to the vehicle by causing the vehicle bottom to catch on the cover of the protruding support portion 16b are caused. As shown in FIG. 5A, a rib is preferably provided on the back surface of the lock plate 14 to reinforce the strength of the lock plate 14.

Next, the upright operation of the lock plate 14 will be described with reference to FIGS. First, when a vehicle sensor (not shown) detects the parked vehicle 6, a lock signal is output from a control device (not shown), and the linear movement mechanism 26 starts moving in the upright direction of the lock plate. Then, as shown in FIG. 7B, the lock plate 14 continues to rotate in the upright direction via the joint 50, the crank 52, the main shaft 55, the cranks 56 and 60, and the rotating shaft 12, and as shown in FIG. When the tip of the lock plate 14 abuts on the bottom of the vehicle 6, the movement of the piston 36, the joint 50, the crank 52, and the lock plate 14 is stopped as shown in FIG. 8B. Thus, the joint 32 of the torque detecting means 30 is moved by the piston 28 as shown in FIG.
Since the driving is continued in the direction of arrow Y in FIG.
As shown in the figure, the limit switch 38a connected to the joint 32 via the case 40 continues to move in the direction of arrow Y in the same figure, and when the limit switch 38a comes into contact with the convex portion 37a provided on the piston 36, the limit switch 38a moves linearly. The stop signal of the mechanism 26 is transmitted from the limit switch 38a to the control device (not shown) via the signal line 44a and the support member 42, the linear movement mechanism 26 stops, and the standing operation of the lock plate 14 ends. In the case where the lock plate 14 is very tall and does not hit the vehicle bottom, the projection 53a provided on the crank 52 comes into contact with the limit switch 54a shown in FIG.
The rising operation of the linear moving mechanism 26 is stopped by the output of the switch 54a. Also, as can be seen from FIGS. 8A and 9A, the torque by which the lock plate 14 presses the vehicle 6 can be adjusted by changing the elasticity of the elastic member 34a. A vehicle at a height can be detected stably.

Next, the falling operation of the lock plate 14 will be described. First, when a parking fee is paid and a lock release signal is output from a control device (not shown), the linear moving mechanism 26 starts moving in the opposite direction to the above. Then, the torque detecting means 30,
The lock plate 14 rotates in the falling direction via the joint 50, the crank 52, and the rotating shaft 12, and if there is no obstacle or the like in the middle, the lock plate 14 continues to fall, and as shown in FIG. The protrusion 53b provided on the limit switch 52
When it comes into contact with 4b, the output of the switch 54b is transmitted to a control device (not shown), so that the linear movement mechanism 26 stops its falling operation. When the lock plate 14 is caught on the projecting portion of the vehicle 6 or sandwiches an obstacle, FIG.
In (B), the rotating shaft 12, the cranks 60 and 56, the main shaft 5
5, the piston 52 through the crank 52 and the joint 50
6 stops, and on the other hand, the limit switch 38b continues to move upward in the drawing via the linear movement mechanism 26, the piston 28, the joint 32, and the case 40. When the limit switch 38b abuts, a stop signal of the linear movement mechanism 26 is output from the limit switch 38b, transmitted to a control device (not shown) via the signal line 44b and the support member 42, and the falling operation of the linear movement mechanism 26 is interrupted. It is supposed to be. Further, the torque of the lock plate 14 during the above-mentioned falling operation can be adjusted by changing the elasticity of the elastic member 34b. Next, the operation of the safety cover 3 will be described with reference to FIGS. First, as shown in FIG. 7 (C), a plurality of thin flat plates 3a to 3d are stacked and arranged on the safety cover 3, and holes h3 and h are formed in each of the flat plates 3a to 3d.
4 are provided, each hole h3 is loosely fitted to the rotating shaft 12, and the flat plates 3a to 3d are engaged with each other via each hole h4. The tip of the flat plate 3d is the lock plate 1
4 is engaged with the rotation of the lock plate 14 and sequentially rotates in the order of the flat plates 3d, 3c,... 3a. For this reason, as shown in FIG. 7 (B), no space is formed between the lock plate 14 and the cover 76 of the drive mechanism 4 for holding a human body such as a limb, and a safe exit prevention device can be realized. it can.

By the way, as shown in FIG. 9 (B), the torque detecting means 30 of the present invention constantly moves and moves in response to the movement of the linear moving mechanism 26.
The signal lines 44a and 44b output from the a and 38b are also constantly moved and moved.
The middle of the signal line was sharply bent, and it was very easy to cut the signal line. The applicant of the present invention has investigated the prior art in order to solve such a problem.
It has been discovered that a cable guide technology of a linear moving mechanism is introduced in Japanese Patent Application Publication No. 9651. The above-mentioned publication introduces a cable guide in which a support member of the cable guide moves while forming a parallel portion parallel to the fixed portion of the movable electric portion and the fixed portion of the stationary power supply portion. On the other hand, in the present invention, as shown in FIG. 9 (E), the torque detecting means 30 which is a movable electric part is not parallel to the flat plate 20 which is a stationary part but moves linearly while forming an angle β, so The signal cables 44a and 44b are laminated on a flexible support member 42 made of a belt-shaped steel material formed in a curved arc shape, and the whole is covered with a sleeve member 46 made of a net-like synthetic resin (FIG. 9C). And (D)) attaching one end of the support member to the cover 40 of the torque detecting means 30 which is a movable part.
8a, and the other end is sandwiched by the member 48b on the flat plate 20 on the immovable portion side and arranged so as to form a linear shape with respect to the movable portion and the immovable portion, respectively. In response to the linear movement of the detection means 30, the support member 42 sequentially changes the length of the two linear portions,
At the intersection of the linear shapes, the shape in which the arc-shaped convex direction in the width direction of the support member 42 was outward or inward is deformed into a flat plate shape, and the support member 42 can move while forming a curved portion having a substantially constant curvature. Observed. When the movement deformation of the curved portion is completed, the respective portions of the support member 42 return to the original convex arc shape curved in the width direction, so that the signal line held and guided is bent at a substantially constant curvature, and the cable is bent. Does not float up or get caught in other protruding portions, it is possible to eliminate accidents such as internal disconnection and poor contact, and to significantly improve the reliability of the device. 3 to 5 in the lock portion 2 of the present invention.
As is clear from FIG. 4, it is possible to increase the number of the support portions 16 to three or more, and to arrange the support portion 16a closest to the drive mechanism portion 4 outside the lock plate 14. The support 70b in the drive mechanism 4 can also serve as the support 16a. Further, the above-described torque detecting means 3
Although all the reference numerals 0 are constituted by mechanical members, a semiconductor pressure element may be provided in parallel with the elastic member to electronically detect the torque.

Next, FIG. 10A corresponding to FIG.
FIG. 10 is a plan view of another example of the present invention, and FIG.
(C) is a cross-sectional view, in which the devices with the same numbers perform the same functions and support portions 16a to 16b.
The lock plate 14 and the rotary shaft 12 are hinged by arcuate grooved arms 17a, 17b. Also in the parking vehicle leaving prevention device having such a configuration, since the support portion 16b of the rotating shaft 12 is located below the slope plate 18, a support portion without a protruding portion can be realized in a state where the lock plate is laid down, which is safe and secure. It is possible to realize a lock portion with a low ride height GL of one wheel.

FIG. 11 corresponding to FIG. 3 shows still another embodiment of the present invention, in which devices having the same numbers perform the same functions and lock the power from the electric motor. In the power transmission mechanism for transmitting the power to the plate, a power transmission unit including two rotating bodies having the same center of the rotating shaft and a winding spring whose diameter changes due to a phase difference between the two rotating bodies is interposed. As the diameter of the spring is reduced, the winding spring is pressed against an outer rotating body in the rotating body. The power of an electric motor (not shown) is converted to linear moving power by a linear moving mechanism 26 such as a hydraulic cylinder. The output is directly connected to the crank 52 via the piston 28. The outer rotating body 80 shown in FIG.
The rotating body 80 is supported by supporting portions 70a and 70b such as bearings and is fixed to the flat plate 20, and the oiles 15c,
15d is press-fitted, and the main shaft 55 is inserted through the inside. Further, a winding spring 8 is provided around the outer periphery of the rotating body 80.
1 is wound, one end of which is locked to the crank 52, the other end of the winding spring 81 is locked to a control pin 82 embedded in the main shaft 55, and the moving range of the control pin 82 is And a proximity sensor 84 is attached to the outer periphery of the rotating body 80 to detect a phase difference between the main shaft 55 and the rotating body 80.

The operation of the above configuration will be described with reference to FIG. First, when the vehicle detector (not shown) detects the parked vehicle 6 in the upright operation of the lock plate 14, a lock signal is output from a control device (not shown), and the linear movement mechanism 2
The piston 28 moves by the power from the electric motor in the motor 6, and the rotary shaft 12 rotates via the crank 52, the rotating body 80, the winding spring 81, the main shaft 55, the crank 56, the safety pin 58 and the crank 60, and the lock plate 14 Rotates in the upright direction. When the tip of the lock plate 14 comes into contact with the bottom of the vehicle 6, the lock plate 14, the cranks 60 and 56, and the main shaft 55 stop moving. However, the linear movement mechanism 26
Keeps driving the piston 28, the crank 52 and the rotating body 80 keep rotating, the proximity sensor 84 attached to the rotating body 80 approaches the stopped control pin 82, and when approaching within a predetermined distance, the proximity sensor 84 When the lock plate 14 is activated, the stop signal of the linear movement mechanism 26 is transmitted to the control device (not shown), and the upright operation of the lock plate 14 is completed. In the case of a vehicle with a high vehicle bottom where the lock plate 14 does not hit the vehicle bottom, the linear movement mechanism 26 can be automatically stopped by the crank 52 and the limit switch 54a as in FIG. By adjusting the number of turns 81, the torque by which the lock plate 14 presses the vehicle 6 can be adjusted. Although the rotating body 80 is driven by the crank 52 in the above-described example, the rotating body can be easily driven by a gear. Next, the falling operation of the lock plate 14 can be performed in the same manner as the falling operation of FIG.

[0014]

As described above, according to the parked vehicle exit prevention device of the present invention, the height of the lock portion can be made extremely low, that is, within 65 mm, so that the vehicle bottom can be damaged even in a modified vehicle having a low vehicle height. It is possible to provide an exit-preventing device without any. Further, since the locking portion is lowered, even a person who is not skilled in driving technology can easily enter and exit the vehicle, and reduce a vehicle accident caused by sudden acceleration caused by blowing the engine. In addition, since a very long plate having a width of 40 cm or more at the tip side of the lock plate can be used, it is possible to absolutely prevent illegal retreat, and since the support portion 16b of the rotating shaft 12 is built in the device and there is no protrusion, , It can also prevent accidents such as a passenger passing over and falling over
Further, since the safety cover 3 is provided, it is possible to prevent an accident such as the lock plate being pinched between the limbs of the human body, which is safe. In addition, it is possible to provide an efficient and easy-to-maintain leaving device for a parked vehicle that has a simple structure that does not cause rattling or chipping even when a heavy lock plate is opened and closed.
