Description

  The present invention relates to a parking apparatus, and more particularly to an apparatus that prevents unauthorized exit of an unsettled vehicle in a pay parking lot.

  Conventionally, in a pay parking lot, a parking device that restrains a parked vehicle is used to prevent unauthorized leaving of an unsettled vehicle. As this type of parking apparatus, a parking device such as a flap plate is generally provided on the ground where a tire of a parked vehicle in front of a parking space is located. For example, Patent Documents 1, 2, What is disclosed in No. 3 etc. is known.

  However, in these parking apparatuses, the parked vehicle may get out of the car stop and exit, and the parked vehicle may not be completely prevented from leaving illegally. In particular, in recent years, a four-wheel drive vehicle or the like having a high vehicle height can easily get over the car stop, and a malicious user sometimes gets out of the car stop without paying the parking fee. In addition, because the car stop is at the bottom of the parked vehicle, it is not easy for the user to notice, and even if it is a good-willed user, if the car accidentally forgets to settle and tries to leave, the car stop will collide with the lower part of the vehicle. However, the vehicle may be damaged, and unforeseen damage may occur to a bona fide user. In particular, since the lower part of the vehicle is vulnerable to external impact, the vehicle is likely to be damaged. In addition, when the vehicle collides with the vehicle stop or when the vehicle goes over the vehicle stop and exits, the parked vehicle may be damaged due to the impact of the collision and the load of the vehicle.

  Therefore, the present inventor has developed a parking device described in Patent Document 4 as a solution to the above problem. This parking device has a swing arm made up of an arcuate bar-shaped member that is pivotally supported at one end by a support member on the vehicle entrance / exit side of the upper space of the parking space, and a center portion that swings. A closing member composed of a horizontal rod-like member connected to the end opposite to the shaft support end of the arm, and a hydraulic cylinder that is a drive mechanism for driving the swing arm to rotate. Is raised and lowered between a free height and a height sufficient to restrict the entry and exit of the vehicle.

  By the way, in the parking apparatus described in Patent Document 4, a pair of support members are provided on both sides of the parking space in order to restrict the vehicle from entering and exiting in such a manner that the closing member is turned forward. A frame member is provided, and a swing arm is pivotally attached to the ceiling frame member so as to be rotatable. Therefore, the height of the vehicle that can be parked in the parking device is limited to the height of the ceiling frame member or less.

  In this parking device, since the swing arm has a curved shape on the side opposite to the side facing the vehicle, the swing arm is lifted when the tip of the closing member of the swing arm is raised to the highest position. The arm is raised to a position higher than this closing member. Therefore, in a place where the height of the upper space of the parking device is limited, there is a problem that the space between the highest position of the swing arm and the ceiling frame member becomes a dead space.

  Therefore, an object of the present invention is to provide a parking device that can eliminate a dead space in an upper space of a parking space and can cope with a vehicle having a high vehicle height.

  The parking device of the present invention is a parking device that regulates the exit of a vehicle parked in a parking space, and is pivotally supported by a column member standing on one side of the parking space and a column member. The swing arm includes a crank-shaped swing arm and a rotation mechanism that rotates the swing arm. The swing arm is rotated by the rotation mechanism, and a closing portion that moves up and down on the vehicle entrance / exit side of the parking space. The rotating shaft portion and the closing portion are connected in a straight line at the shortest distance and are configured by a handle portion that rotates at the side portion of the parking space.

  In the parking apparatus according to the present invention, the swing arm is pivotally supported by a support member standing on one side of the parking space and rotates. Therefore, the upper space of the parking space is limited by the conventional support portion of the swing arm. There is nothing to do. The swing arm itself also moves up and down on the vehicle entrance / exit side of the parking space by rotating the handle portion that connects the rotation shaft portion and the closing portion in a straight line at the shortest distance on the side of the parking space. In the upper space of the parking space, the closed portion is the highest position, and the dead space in the upper space of the parking space can be eliminated.

  Here, the rotation mechanism includes a crank arm whose one end is connected to the rotation shaft portion of the swing arm, a drive mechanism that is pivotally supported by the crank arm and rotates the swing arm by extending and contracting, and a shaft mounted on the crank arm. It is desirable to include a spring that is supported and that exerts a moment on the crank arm that is balanced with the moment around the rotating shaft of the swing arm due to the load of the swing arm.

  By configuring the pivot mechanism in this way, the moment caused by the load of the swing arm is canceled out by the reaction force of the spring, and when the swing arm is pivoted, the moment is not affected by the load and closed with a small force. It is possible to raise and lower the portion between a height at which the vehicle can freely enter and exit and a height sufficient to restrict the vehicle from entering and exiting. Accordingly, it is possible to use a small output power source as the drive source of the drive mechanism.

  Here, the degree of balance with the moment around the rotation axis of the swing arm due to the load of the swing arm does not have to be completely balanced with the moment around the axis of the swing arm due to the load of the swing arm, and some unbalance is allowed. Means that. In short, it suffices if the closing part can be raised and lowered with a small force while minimizing the influence of the moment caused by these loads when the swing arm is rotated.

  Note that “the height at which a vehicle can freely enter and exit” refers to a height that is higher than the maximum vehicle height of a vehicle that is supposed to be parked in a parking lot, and differs depending on the type of vehicle that is supposed to be parked in the parking lot. When this parking apparatus is used in a parking lot such as a general coin parking, it is set to a height higher than the maximum vehicle height of a normal passenger car or one box or minivan. In addition, “high enough to regulate the entry and exit of the vehicle” means a height at which the parked vehicle cannot collide with the closed part when it tries to leave the parking space. Lowering the closing part to the front of the front windshield is sufficient to prevent the vehicle from leaving, and alerting the parking lot user when leaving the parked vehicle. This is because it is possible to make things easier to notice.

  Moreover, it is desirable that the drive mechanism and the spring according to the present invention be provided in a substantially vertical direction along the side surface of the column member. In the parking device of the present invention, the closing portion can be moved up and down with a small force by the crank arm and the spring, and the drive mechanism is provided along the side surface of the column member together with the spring, so that the rotation mechanism is mounted on the vehicle. While being able to downsize so as not to obstruct access, the drive mechanism can be maintained even when the vehicle is in the parking space.

  The spring is preferably a gas spring. Generally, a gas spring is provided with a piston that slides in an axial direction integrally with a rod inside a cylinder, and is filled with compressed gas inside the cylinder divided into two chambers by the piston. The two chambers communicate with each other through an orifice provided in the piston, and the area on the rod side of the piston that receives gas pressure is smaller than the opposite side, so that the rod always exhibits a reaction force in the extending direction. . Since such a gas spring has a small spring constant, an almost constant reaction force can be obtained over a wide range of strokes. Therefore, regardless of the position of the crank arm, that is, the position of the swing arm, the moment around the axis of the swing arm due to the load of the swing arm can be canceled by a substantially constant reaction force, and the closing part can be raised and lowered smoothly. It becomes.

  Further, the parking device of the present invention is configured such that when the closing portion is in the vicinity of the position where the horizontal distance from the rotating shaft portion of the swing arm to the closing portion is the farthest, the shaft fulcrum of the crank arm of the spring and the rotating shaft portion of the swing arm. It is desirable that the line connecting the two and the reaction force line of the spring be substantially orthogonal. As a result, the moment around the axis of the swing arm due to the load of the swing arm becomes the largest when the closing portion is in the vicinity of the farthest horizontal distance from the rotating shaft portion of the swing arm to the closing portion. The line connecting the pivot point of the crank arm of the spring and the rotation shaft of the swing arm is substantially perpendicular to the spring reaction force line, so that the spring reaction force causes the swing arm to move around the axis of the swing arm. Since the moment for canceling the moment can be maximized, the balance with the moment around the axis of the swing arm due to the load of the swing arm can be most efficiently balanced.

(1) A swing arm provided with a support member standing on one side of the parking space, a crank-like swing arm pivotally supported by the support member, and a rotation mechanism for rotating the swing arm. The rotating shaft driven by the rotation mechanism, the closing portion that moves up and down on the vehicle entrance / exit side of the parking space, the rotating shaft portion and the closing portion are connected in a straight line at the shortest distance and the side of the parking space The upper part of the parking space is not restricted by the conventional swing arm support part, and the closed part is the highest position in the upper part of the parking space. Thus, since the dead space in the upper space of the parking space can be eliminated, it is possible to deal with a vehicle having a high vehicle height.

(2) The rotating mechanism includes a crank arm having one end connected to the rotating shaft of the swing arm, a drive mechanism that is pivotally supported by the crank arm and moves up and down by extending and contracting, and a pivot supported by the crank arm. And a spring that acts on the crank arm with a moment that balances the moment around the rotation axis of the swing arm due to the load of the swing arm, so that a small output can be achieved without using an expensive hydraulic cylinder. It is possible to operate the closing portion using the drive source, and it is possible to provide an inexpensive parking device.

(3) It is desirable that the drive mechanism and the spring are provided in a substantially vertical direction along the side surface of the support member. Accordingly, the rotation mechanism can be reduced in size so as not to obstruct the entry / exit of the vehicle, and the drive mechanism can be maintained even when the vehicle is in the parking space.

(4) Since the spring is a gas spring, regardless of the position of the crank arm, that is, the position of the swing arm, the moment around the axis of the swing arm due to the load of the swing arm can be canceled by a substantially constant reaction force. It is possible to smoothly raise and lower the closing portion.

(5) When the closing portion is in the vicinity of the position where the horizontal distance from the rotating shaft portion of the swing arm to the closing portion is the farthest, the point connecting the shaft supporting point of the crank arm of the spring and the rotating shaft portion of the swing arm and the spring By making the reaction force line almost perpendicular, the most efficient balance with the moment around the axis of the swing arm due to the load of the swing arm can be achieved, and the cost of the spring can be reduced to obtain an inexpensive parking device. Is possible.

  1 is a perspective view of a parking device according to an embodiment of the present invention, FIG. 2 is a front view of the parking device of FIG. 1, and FIG. 3 is a right side view of FIG.

  In FIG. 1, a parking lot ground 1 is paved with concrete or asphalt, and a rectangular frame-like parking frame 2 is drawn by a white line for each vehicle parked so as to surround the parking space 1a.

  The swing arm 6 includes a rotary shaft portion 6a that is rotationally driven by the rotation mechanism 10, a closing portion 6b that moves up and down on the vehicle entrance / exit side of the parking space 1a, and the rotary shaft portion 6a and the closing portion 6b in a straight line at the shortest distance. And a handle 6c that rotates at the side of the parking space. The rotating shaft portion 6a is a shaft member having a regular hexagonal cross section, and is disposed at a right angle and horizontally with respect to the vehicle exit / entry direction. Moreover, the bar | burr bent in the L-shape which comprises the closure part 6b and the handle | pattern part 6c is being fixed to the front-end | tip of the rotating shaft part 6a. The closing portion 6b is parallel to the rotating shaft portion 6a, and the handle portion 6c is perpendicular to the rotating shaft portion 6a and the closing portion 6b. That is, the handle 6c connects the rotary shaft 6a and the closing part 6b in a straight line with the shortest side distance of the parking space. Further, a rubber disc-shaped cushioning material 6d is provided at the tip of the closing portion 6b.

  4 is a partially enlarged cross-sectional view of the rotation mechanism 10 of FIG. 3, and FIG. 5 is a view taken in the direction of arrow A showing the main part of FIG.

  As shown in FIGS. 4 and 5, the rotation mechanism 10 includes a crank arm 20 connected to the rotation shaft portion 6 a, a gas spring 21 as a spring supported by the crank arm 20, and an actuator 22 as a drive mechanism. And have. The crank arm 20 is bent into a U-shape, and a regular hexagonal insertion hole 20a for inserting and fixing the rotary shaft 6a is formed at one end, and a gas is formed at the other end. A shaft 20b that rotatably supports the spring 21 and the actuator 22 is provided.

  The gas spring 21 is provided with a piston (not shown) that slides in the axial direction integrally with the rod 21b inside the cylinder 21a, and the cylinder 21a divided into two chambers by the piston is filled with compressed gas. Is something. The gas spring 21 has both chambers communicated with each other by an orifice (not shown) provided in the piston, and the chamber on the rod 21b side of the piston has a smaller area for receiving gas pressure than the opposite side. Therefore, the rod 21b always exhibits a reaction force in the extending direction. The gas spring 21 is disposed along the column member 5 and is rotatably supported by a shaft 21c.

  The actuator 22 includes a feed motor 22a and a rod 22b that expands and contracts by converting the rotation of the feed motor 22a into a linear motion using a ball screw (not shown) or the like. The actuator 22 is disposed along the column member 5 together with the gas spring 21, and is rotatably supported by a shaft 22c.

Crank arm 20, the position of S _L shown by a solid line in FIG. 4 (hereinafter, referred to as "lower position".) And the position of S _H indicated by a dashed line (hereinafter, referred to as "upper limit position".) Between at Rotate. When the crank arm 20 is in the lower limit position S _L and an upper limit position S _H, the swing arm 6 is in the position of S _H indicated by the position and a dashed line S _L shown in FIGS. 2 and 3, respectively by a solid line. Although not shown, the rotation mechanism 10, a limit switch for stopping the operation of the actuator 22 by detecting the lower limit position S _L and an upper limit position S _H are provided respectively. In the illustrated example, the rotation angle of the rotation shaft 6a from the lower limit position S _L to the upper limit position S _H is 135 °, the lower limit position S _L and an upper limit position S _H is adjustable arbitrarily.

  Further, in the parking device 4 according to the present embodiment, the closing portion 6b is the farthest horizontal distance from the rotation shaft portion 6a of the swing arm 6 to the closing portion 6b (the position where the handle portion 6c of the swing arm 6 is horizontal). ) When in the vicinity, the line connecting the shaft 20b of the crank arm 20 of the gas spring 21 and the rotating shaft portion 6a of the swing arm 6 and the reaction force line of the gas spring 21 are in a position substantially orthogonal. At this position, the gas spring 21 is balanced with the moment around the rotating shaft 6a of the swing arm 6 due to the load of the swing arm 6 (actually, the moment around the rotating shaft 6a of the swing arm 6 due to the load of the swing arm 6). Is set to a spring force that acts on the crank arm 20. Therefore, in the parking device 4 in the present embodiment, the moment due to the load of the swing arm 6 is canceled by the reaction force of the gas spring 21 at this position, so that the swing arm 6 can be rotated with a small force.

  About the parking apparatus 4 in this embodiment comprised as mentioned above, the operation | movement is demonstrated below. FIG. 6 is a schematic diagram showing the operation of the parking device 4 of FIG. 1, wherein (a) shows a case where a normal passenger car 100 is parked as a parking vehicle in the parking space 1a, and (b) shows parking in the parking space 1a. It is a figure which shows the case where the one box car 101 parks as a vehicle.

First, before a parked vehicle such as the ordinary passenger car 100 or the one-box car 101 enters the parking space 1a, the actuator 22 is extended, the swing arm 6 is in the raised position, and the closing portion 6b is at the highest position A. (The position of _SH shown in FIGS. 2 and 3). In this state, the distance between the closed portion 6b and the cushioning material 6d and the parking lot ground 1 is higher than the vehicle height of the parked vehicle, and the handle 6c is on the side of the parking space 1a. You can freely enter and leave the space 1a.

  When the parked vehicle enters the parking space 1a, the actuator 22 contracts, the swing arm 6 rotates, and stops when the closing portion 6b descends to a point B high enough to restrict the entry and exit of the vehicle. . At this time, the trajectory of the closing portion 6b is an arc-shaped trajectory centered on the rotation shaft portion 6a. In the state where the closed portion 6b is lowered to the point B, the parked vehicle is surrounded by the left and right support members 5 and the closed portion 6b, and cannot leave the parking space 1a. As a result, unauthorized exit of the unsettled vehicle can be reliably prevented.

  When the parking device 4 is used in an unmanned parking lot, the sensor detects that the parked vehicle has entered the parking space 1a, and the control device activates the actuator 22 by this detection signal to rotate the swing arm 6. The closing portion 6b is lowered. In this case, a sensor is provided in the closing portion 6b, and the control device stops the contraction of the actuator 22 when the closing portion 6b approaches the parked vehicle to a predetermined distance. As a result, the contraction of the actuator 22 can be stopped when the closing portion 6b descends to a point B that is high enough to restrict entry and exit of the vehicle.

  Here, the handle 6c of the swing arm 6 rotates at the side of the parking space 1a to raise and lower the closing part 6b. Therefore, when the swing arm 6 is rotated to lower the closing part 6b, The handle 6c does not contact the parked vehicle. Therefore, according to the parking device 4 in the present embodiment, only the closed portion 6b exists in the upper space of the parking space 1a, and the maximum height of the vehicle that can be parked is when the closed portion 6b is at the highest position A. .

  In addition, when using the parking apparatus 4 in an unmanned parking lot, if it detects that the user input the parking charge at the time of payment, a control apparatus will start the actuator 22 and will raise the closing part 6b. Thereby, it becomes possible to use the parking apparatus 4 also in an unmanned parking lot. In addition, as described above, the parking device 4 according to the present embodiment has a configuration in which the closing portion 6b is lowered at the front portion of the parked vehicle to prevent the vehicle from leaving. It is possible to prevent a user of a good-willing parking lot from leaving without being settled.

  By the way, in the parking device 4 in the present embodiment, the sensor provided in the closing portion 6b as described above stops the contraction of the actuator 22 when the closing portion 6b approaches the parked vehicle to a predetermined distance. It is also assumed that the sensor has failed or the parked vehicle has an unexpected projection. In such a case, it is assumed that the contraction of the actuator 22 does not stop and the cushioning material 6d at the tip of the closing portion 6b contacts the vehicle even though the distance between the closing portion 6b and the vehicle is equal to or less than a predetermined threshold. The

  Therefore, the parking device 4 in the present embodiment includes a safety mechanism 30 (see FIG. 4) that stops the descent of the closing portion 6b when the closing portion 6b comes into contact with the vehicle. The safety mechanism 30 pivotally supports the shaft 22c of the actuator 22, and includes a slider 31 that is slidable substantially parallel to the direction of expansion and contraction of the actuator 22 (vertical direction in the example of FIG. 4), and the slider 31. An auxiliary spring 32 that biases the actuator 22 in a substantially extending direction (downward in FIG. 4) and a switch 33 that stops the operation of the actuator 22 when the slider 31 slides a predetermined amount in the substantially contracting direction of the actuator 22 are provided. .

FIG. 7 is an operation explanatory diagram of the safety mechanism 30.
The slide direction of the slider 31 is restricted to the vertical direction, and the slider 31 is restricted to slide only between the position shown in FIG. 7A and the position shown in FIG. Further, in the parking device 4 according to the present embodiment, a moment that is slightly lost with respect to the moment around the rotation shaft portion 6 a of the swing arm 6 due to the load of the swing arm 6 is applied to the crank arm 20 by the gas spring 21. Therefore, the load of the swing arm 6 is slightly applied to the actuator 22 (force F _{1 in} FIG. 7A). Therefore, a vertically downward force F ₂ acts on the slider 31, and the slider 31 is slid to the position shown in FIG. 7A regardless of the expansion / contraction operation of the actuator 22.

Further, since the slider 31 is urged vertically downward (force F ₃ ) by the auxiliary spring 32, the moment that acts on the crank arm 20 by the gas spring 21 and the swing arm due to the load of the swing arm 6 and the closing portion 6 b. 6 is in a state in which the slider 31 is slid to the position shown in FIG. 7A even in a state where the moment around the rotating shaft portion 6a is completely balanced (F ₁ = 0). In short, the auxiliary spring 32 only needs to have an urging force that can maintain the state in which the slider 31 is slid vertically downward regardless of the expansion / contraction operation when the actuator 22 is expanded / contracted.

In the safety mechanism 30 configured as described above, when the swing arm 6 is lowered by operating the actuator 22 to contract, the swing arm 6 comes into contact with the parked vehicle 102 for some reason. 7 (b), the force F ₁ applied to the actuator 22 is released by the reaction force F ₄ from the parked vehicle 12, and the actuator 22 is contracted to apply an upward force F ₅ to the slider 31. Then, the slider 31 slides vertically upward. When the slider 31 slides by a predetermined amount and reaches the position shown in FIG. 7B, the switch 33 is activated to stop the contraction operation of the actuator 22. Therefore, the swing arm 6 does not descend any further, and the parked vehicle 102 can be prevented from being damaged.

  The parking device of the present invention prevents unauthorized exit of an unsettled vehicle in a pay parking lot, and alerts the parking lot user when leaving the vehicle. It is useful as a device that prevents the user from exiting.
