[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a gate device, and more particularly to a gate device which temporarily blocks a route for entering and leaving when entering or leaving a predetermined area such as a parking lot.

[0002]

2. Description of the Related Art Conventionally, entering / leaving a parking lot, entering / leaving a designated management facility, entering a toll area, etc.
When entering or leaving a designated area, a gate device is provided to temporarily block the route connecting the designated area and other areas in order to prevent unauthorized entry or removal. Has been. In particular, in a paid parking lot or the like, entrance control, charge collection, and exit control are often performed unattended, and a gate device is always arranged. Of course, even in the manned management state, the gate device is used to perform the above-mentioned management.

FIG. 5 shows a conceptual diagram of the structure of a conventional gate device 100 arranged in a parking lot or the like.

In the example of FIG. 5, the gate device 100 is
As shown in the top view of FIG. 5A, it is arranged on the side of a dedicated path 102 that connects the inside and the outside of the parking lot. This gate device 100 is a straight type blocking bar (made of metal or the like, which is connected at right angles to a drive unit 104 formed of a motor or the like and a rotary shaft 104a extending from the drive unit 104 substantially parallel to the passage direction of the path 102. Wooden) 1
And 06. The control unit that controls the drive unit 104 may be integrated with the drive unit 104 or may be arranged at an arbitrary external position. In addition, the control panel (not shown) actually operated by the user, for example,
There are a parking ticket insertion slot, a charge collection slot, a change discharge slot, a display device for guiding the operating method and the processing state, and the like. The control unit may be incorporated in this control panel. When the gate device 100 is arranged on the exit side, the control panel is arranged inside the front parking lot of the blocking bar 106.

FIG. 5B shows the gate device 1 of FIG.
It is the front view which looked at 00 from the outside of the parking lot. As shown in FIG. 5B, the gate device 100 is, for example, in a horizontal state (solid line) so that the blocking bar 106 blocks the passage direction (retreating direction) of the path 102 in a steady state, and the vehicle or person It is possible to block the passage of. In addition, when a certain passage condition is satisfied, for example, when the usage fee is paid or a usage permit card is presented, the control unit
The rotation shaft 104a of the drive unit 104 is rotationally driven, and the blocking bar 106 is cantilevered by about 90 ° in a plane orthogonal to the passage direction of the route 102 as shown by the alternate long and short dash line, so that the route 102 of the vehicle or person is rotated. Allow the passage of. Then, the control unit confirms that the vehicle or person permitted to pass the passage is completed by a sensor (not shown) or the like, and then again passes through the route 102.
The rotary shaft 104a is rotated in the reverse direction so as to shut off the shutoff bar 106, and the shutoff bar 106 returns to the horizontal closed state. As a result, it is possible to prevent the passage of vehicles and people whose passage has not been confirmed.

As described above, in the conventional gate device, the rotary shaft 104a of the drive unit 104 is provided in parallel with the path 102, and the shut-off bar 106 is opened / closed only by controlling the rotation of the rotary shaft 104a. It is structurally easy to handle and is widely used.

[0007]

Normally, the blocking bar is formed of a single rod (straight bar) having a width equal to or longer than the width of the path, but the gate device is indoors with a ceiling or has a roof. When placed inside the gate, the length of the barrier bar is constrained by ceiling height and roof height, and the barrier bar must be shortened, and the entire width of the route cannot be blocked, allowing slip-through. In addition, if the blocking bar is not shortened, the blocking bar cannot be completely retracted from the path at the time of opening, which may cause interference with passing objects. Had a problem. Therefore, if there is no height constraint, a straight bar is adopted, and if there is a height constraint, the blocking bar bends near the center of the blocking bar when opened (for example, a dogleg shape), or a drive bar. Parts are provided on both sides of the route, and a structure is adopted in which the route is blocked by two short straight bars.
There is a problem that it is necessary to provide a plurality of types of gate devices depending on the installation location of the gate device, which reduces the versatility of the gate device. Further, the refraction type bar apparently blocks the path, but it has a problem that it is easily bent at the refraction part by lifting the tip end by hand, and it is easy to illegally slip through it. There is a problem that the function of blocking the route cannot be fulfilled. Although it is conceivable to provide a lock mechanism at the tip of the refraction type bar, since it bends at the center, the tip of the bar can be easily pulled out from the lock mechanism, and a sufficient effect cannot be obtained. Further, the one using two short straight bars has a problem that a plurality of driving parts are required and the cost is increased.

The present invention has been made in view of the above-mentioned problems, and provides a gate device capable of surely blocking a route with a simple structure without being restricted by an installation place, particularly a height restriction. With the goal.

[0009]

In order to achieve the above-mentioned object, the present invention is characterized in that at least one of entering and leaving a predetermined area is performed by using a predetermined route. A gate device for temporarily blocking passage of a route, the drive unit having a rotating shaft extending in the width direction of the route, a blocking bar extending across the route in the width direction of the route, and the blocking bar. A connecting arm that is fixed to one end of the rotary arm and that is fixed to the rotary shaft at the other end, and that connects the blocking bar to the rotary shaft while offsetting it, And a control unit for performing opening and closing, and the blocking bar moves while maintaining a parallel state with the plane of the path.

Here, the predetermined area means, for example, a parking lot, a predetermined management facility, an expressway, or an area for which entry or exit restrictions are set regardless of whether it is charged or free.

According to this structure, even if a blocking bar having a length equal to or longer than the width of the path is used, the blocking bar moves parallel to the surface of the path, so that there is no restriction on the installation location. It is possible to perform blocking and opening operations of the entire width of the path by the blocking bar. In addition, since the blocking bar can be operated by a single driving unit, the required blocking and opening operations can be performed at low cost.

In order to achieve the above-mentioned object, the present invention is characterized in that, in the above-mentioned structure, it has a bar catcher for holding the blocking bar stationary when the blocking bar is blocked.

Here, the bar catcher has a receiving structure capable of supporting an arbitrary position of the blocking bar, for example, a tip portion, and further, the blocking bar is operated during the blocking operation of the blocking bar, that is, during the blocking control by the controller. It is desirable to have a locking mechanism that locks in position.

According to this structure, distortion and deformation of the blocking bar extending to the position offset from the rotation axis at rest can be reliably prevented, the entire width of the path can be blocked, and the blocking bar driving unit is driven. The load of can be reduced.

In order to achieve the above object, the present invention is characterized in that, in the above structure, the connecting arm has a non-linear shape.

The term "non-linear shape" as used herein includes, for example, an arcuate curved shape, a curved bent shape, a crank-shaped multi-stage shape, and the like.

According to this structure, even if there is an obstacle between the rotating shaft and the offset blocking bar, the blocking bar can be moved by the rotation of the rotating shaft, so that the path blocking and opening operations can be smoothly performed. It can be carried out.

In order to achieve the above-mentioned object, the present invention is characterized in that, in the above-mentioned structure, the control section can set a maximum height when the blocking bar is opened.

Here, the setting of the maximum height is the maximum movement height of the blocking bar which moves while maintaining the parallel state with the plane of the path. This maximum moving height can be set according to the rotation angle of the rotating shaft. For example, when the gate bar of the gate device is subject to height restrictions such as the ceiling, it is only necessary to adjust the rotation angle. Can be evacuated to the very limit of the ceiling, that is, to the height at which a passing object can be used.

According to this structure, it is possible to deal with the height limitation of the installation location of the gate device only by adjusting the rotation angle of the rotary shaft, and the versatility of the gate device can be achieved without increasing the cost. It can be improved easily.

In order to achieve the above-mentioned object, the present invention is characterized in that, in the above-mentioned structure, the control section can set a minimum height when the blocking bar is blocked.

Here, the setting of the minimum height is the minimum movement height of the blocking bar which moves while maintaining the parallel state with the plane of the path. This minimum moving height can also be set according to the rotation angle of the rotating shaft, and for example, the height of a passing object, that is, a parking lot for small and medium-sized vehicles such as passenger cars The height is set to prevent passage, and for large vehicles, the height can be set according to the height. Similarly, if it is for human beings, it can be set to the waist height of an adult or the like. At this time, since the blocking bar moves parallel to the plane of the route, the route can always be blocked in the optimum state even if the minimum height is arbitrarily changed.

According to this structure, even when the installation location of the gate device or the passing object changes, the interruption height can be adjusted only by adjusting the rotation angle of the rotary shaft, so that the versatility of the gate device is not increased. Can be easily improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention (hereinafter referred to as an embodiment) will be described below with reference to the drawings.

FIG. 1 shows, as an example, a conceptual diagram of the structure of a gate device 10 of this embodiment arranged in a parking lot or the like.

FIG. 1A is a top view of a dedicated path 12 connecting the inside and the outside of the parking lot as seen from above, and FIG. 1B is the gate device 10 of FIG. 1A. It is the front view which looked at from the outside of a parking lot. In FIG. 1, for example, the route 12 has a width A that allows one vehicle that can be accommodated in the parking lot to pass through, and the gate device 10 is fixed to the right side of the route 12. It should be noted that partition walls 14 are provided on the left and right of the route 12 to prevent unauthorized movement of the vehicle (for example, movement that has not been paid for usage fees) and unauthorized entry, so that the inside and outside of the parking lot can be completely separated. .

As in the conventional example, the gate apparatus 10 includes a drive unit 16 including a drive source composed of a motor and a gear, and a rotary shaft 16a which is rotationally driven by the motor, thereby forming a path 1.
2. Shut-off bar 18 and drive unit 16 for shutting off and opening
And a control panel 20 including a control unit for driving and controlling The blocking bar 18 has a straight rod-like shape made of metal or wood as in the conventional case, and has a predetermined strength and weight. In addition, the control panel 20, for example,
It has a parking ticket insertion slot, a fee collection slot, a change outlet, and a display device for guiding the operating method and processing state, and can be actually operated by the user. Of course, the drive unit 16 and the control panel 20 may be integrally formed.
May be arranged at another arbitrary position. Similarly, the drive unit 1
The control unit for controlling 6 may be integrated with the drive unit 16 or the control panel 20 or may be provided at another place.

The characteristic feature of this embodiment is that the rotary shaft 16a of the drive unit 16 extends in the width direction of the path 12 and the blocking bar 18 is connected so as to be offset by a predetermined amount with respect to the rotary shaft 16a. Which has a connecting arm 22 for rotating the rotary shaft 16a, the shut-off bar 18 causes the path 12 to move.
It is about to move while maintaining a parallel state with the surface 12a.

The operation of the gate device 10 thus constructed will be described. In this embodiment, the gate device 10 is located on the right side with respect to the passage direction in the path 12, the blocking bar 18 moves up and down (rotates) in front of the rotation shaft 16a, and the connection arm 22 has a linear shape. The case will be described.

In the steady state of the gate apparatus 10, that is, in the state where the passage of the path 12 is blocked, the rotating shaft 16a is rotated.
Has stopped by turning to the rotational position set in the counterclockwise direction. At this time, when the connecting arm 22 has a linear shape, the blocking bar 18 is located at the lowermost end when the connecting arm 22 stands vertically below the rotating shaft 16a as shown in the state a of FIG. Is. Also, as shown in FIG.
In the example of (b), as clearly shown in the state b of FIG. 2, the state is inclined downward by about 45 ° with respect to the horizontal.
The blocking bar 18 rotates the rotating shaft 16a,
It moves along an arcuate trajectory whose radius is the length of the connecting arm 22 about the rotation axis 16a, while maintaining parallel to the surface 12a of the path 12.

As a result, the minimum height of the blocking bar 18 can be arbitrarily set according to the rotation angle of the rotary shaft 16a.
For example, when the gate device 10 is installed in a parking lot exclusively for small / medium-sized vehicles and when it is placed in a parking lot exclusively for large vehicles, it is only necessary to change the setting of the rotation angle of the rotating shaft 16a. Since the block height by 18 can be arbitrarily selected, the same gate device 10 can be used, and it is possible to reliably prevent unauthorized passage of a vehicle using the parking lot.

In the example of FIGS. 1A and 1B, the shutoff bar 1
When 8 is located at the set minimum height, a bar catcher 24 that supports the tip of the blocking bar 18 and holds it stationary is arranged. In the case of this embodiment, the blocking bar 1
8 is a cantilevered state by the connecting arm 22 and exists at a position separated by the length of the connecting arm 22 from the rotating shaft 16a, so that a large load is applied to the rotating shaft 16a and the stationary state of the rotating shaft 16a is maintained. Therefore, a large brake mechanism is required inside the drive unit 16 and the like, resulting in an increase in size of the apparatus and an increase in cost. Further, the blocking bar 18 and the connecting arm 22 are deformed or distorted. In order to prevent this, a bar catcher 24 that supports the tip side of the blocking bar 18 is provided. In the case of the present embodiment, the receiving member simply has a substantially L-shaped cross section for receiving the blocking bar 18. However, in order to prevent fraudulent acts such as lifting the blocking bar 22 in the blocking state, for example, a lock mechanism, for example, a control unit. It is desirable to provide a hook or the like that operates in response to a signal from.
In the case of the present embodiment, the blocking bar 18 and the connection arm 22 are fixed so as to be substantially at a right angle, but bending is likely to occur at this portion. Therefore, as shown in FIG. 1B, it is preferable to provide reinforcing beams 26, reinforcing metal fittings, and the like at the connecting portion.

Next, the opening operation of the gate that allows passage through the path 12 will be described. When the user moves out of the paid parking lot, the general operation of the control panel 20 that the user performs is to insert the parking ticket into the slot for settlement, to settle the settlement fee, etc., and confirm these operations. After that, the control unit operates the drive unit 1.
A rotation instruction of the rotary shaft 16a is output to 6, and in the present embodiment, the rotary shaft 16a is rotated clockwise by a predetermined angle. Here, the predetermined angle is a retracted height (moving maximum height) of the blocking bar 18 which is set in advance, and is set, for example, by the ceiling height or the like of the place where the gate device 10 is installed. For example, when there is a sufficient ceiling height, as shown in the state c of FIG.
Rotate above a to stand vertically. In this case, the blocking bar 18 moves along the arcuate trajectory S to the maximum height. As a result, the vehicle retreats to a position where it does not interfere with a passing vehicle. Further, for example, in FIG. 2, the ceiling height is
When the height is H, the rotation angle of the rotary shaft 16a is adjusted to stop the rotation of the rotary shaft 16a at the position of the state d, that is, the movement of the blocking bar 18 is stopped. In this case, the blocking bar 18
While maintaining the state of being parallel to the surface 12a of the path 12, it rises to the highest position, that is, the height of the ceiling. Since the height of the vehicle leaving the parking lot is naturally lower than the height H of the ceiling, the raised blocking bar 18 is of a height high enough not to interfere with the vehicle, that is, it is substantially optimal without being restricted in height. Can be moved to a position. The blocking bar 1
By providing a bar catcher that holds the blocking bar 18 at the maximum movement position of 8, the stationary stability at the maximum movement position can be improved.

In this way, the blocking bar 18 extending in the width direction of the path 12 is connected by the connecting arm 22, and the connecting arm 22 is driven by the rotation of the rotating shaft 16a extending in the width direction of the path 12, thereby breaking the blocking bar. It becomes possible to move 18 while maintaining the parallel state with the surface 12a of the path 12, and without restricting the height, a straight type blocking bar 18 having a length equal to or longer than the width A of the path 12 is provided. Can be used. As a result, the blocking function of the path 12 can be sufficiently exerted. Further, since the blocking bar 18 can be operated by a single drive source, it is possible to suppress an increase in cost.

Further, as described above, the cutoff bar 18 is simply changed by changing the rotation angle of the rotary shaft 16a of the drive unit 16.
Since the maximum moving height and the minimum moving height can be arbitrarily set, the gate apparatus 10 can be arranged at various installation locations only by setting the rotation angle of the rotating shaft 16a.
That is, it is possible to arrange the same gate device 10 even in a parking lot where the ceiling height and the roof height of the gate are different, and also in a parking lot where the size of the vehicle to be used is different.
A desired motion effect can be obtained.

As described above, the maximum and minimum heights of movement of the blocking bar 18 can be set arbitrarily, so that the gate device 10 of the present embodiment is installed in a parking lot for large vehicles such as trucks. When used, the minimum movement height of the blocking bar 18 is in the state e of FIG. 2 or in the state d according to a high vehicle height.
There may be cases such as. Similarly, for small cars and humans, the maximum height may be in the state e. That is, it is possible to properly use the same type of gate device according to the intended use, and it is possible to improve the versatility of the gate device 10.

1 and 2, the connecting arm 2
2 shows a straight type, but a curved connecting arm 22a may be used as shown in FIG. 3, for example. By using the connecting arm 22, the blocking bar 18 is driven at a position offset from the place where the drive unit 16 and the like are arranged. In this case, the interfering object B may be present between the drive unit 16 and the blocking bar 18. In such a case, by bending the connecting arm 22 like the connecting arm 22a, the interference object B
It is possible to easily avoid interference with the gate device 10 and operate the gate device 10 while maintaining the operation function of the blocking bar 18 described above. Of course, the shape of the connecting arm 22 connects the rotary shaft 16a extending in the width direction of the path 12 and the blocking bar 18, and the blocking bar 1 is rotated by the rotation of the rotary shaft 16a.
8 can be arbitrarily changed based on the shape, size, etc. of the interferer B as long as it is configured to move 8 in parallel with the surface 12a of the path 12. As shown in FIG.
The same effect can be obtained by using b or a crank type having a plurality of bends.

Further, in the present embodiment, when the connecting portion between the cutoff bar 18 and the connecting arm 22 and the connecting portion between the connecting arm 22 and the rotary shaft 16a are on the same plane, that is, the connection relationships are substantially right angles, and the connection is made. Although the case where the arm 22 is parallel to the passage direction of the path 12 is shown, the connection does not have to be a right angle, and each connection angle is an obtuse angle or an acute angle, that is,
It may be inclined with respect to the passage direction of the path 12.

Further, in the above-described embodiment, the blocking bar 1
Although the example of presetting the maximum and minimum heights of movement of 8 is shown, for example, the size and height of the vehicle that has entered the route 12 for leaving the parking lot is detected by a sensor or the like, According to the detection result, the blocking bar 18 blocking the path 12
It is also possible to appropriately change the height of the door and the withdrawal height when opened. By controlling in this way, the blocking bar 18 blocking the route 12 may enter a blind spot as seen from the user's position, or the blocking bar 18 being evacuated may come into contact with a passing vehicle. Inconvenience can be reliably eliminated. Of course, the change based on the detection result may be continuous control or stepwise control at predetermined intervals.

Further, if the connecting arm 22 is configured to be expandable and contractible so that the initial setting can be changed, the rotating shaft 16a
It is possible to change the offset amount from the to the blocking bar 18, and it is possible to further adjust the maximum moving height of the blocking bar 18 according to the installation location of the gate device 10. In addition, if the blocking bar 18 is also configured to be expandable and contractible so that the initial setting can be changed, the route 1 for installing the gate device 10
It can be easily adapted to a width A of 2. In addition, it is desirable that the elastic structure has a lock mechanism so that it cannot be changed illegally.

In the present embodiment, the example in which the gate device 10 is arranged at the exit of the parking lot has been shown, but the gate device 10 is installed at a place where a predetermined route is used to enter or leave a predetermined region. It is possible, for example, to be arranged at the entrance / exit of a specific facility or the entrance / exit of a toll road, and the same effect can be obtained. Further, the gate device of the present embodiment can be applied to a gate that is commonly used for entrances and exits, and similar effects can be obtained. Furthermore, in this embodiment,
Although an example in which a vehicle passes through the route 12 is shown, the present invention is not limited to the vehicle, and can be applied to a case where it is desired to temporarily block the passage of an arbitrary object including the passage of a human, and the same effect as the present embodiment. Can be obtained.

If the blocking bar 18 extending in the width direction of the path 12 is connected by the connection arm 22 and the connection arm 22 is driven by the rotation of the rotary shaft 16a extending in the width direction of the path 12, The structure and shape can be appropriately selected, and the same effect as that of the present embodiment can be obtained.
