Description

  The present invention relates to a car stop device used in a place where a vehicle enters, such as a parking lot, and more particularly to a movable car stop device that can take a state of being embedded in the ground and a state of protruding from the ground.

  Conventionally, various movable car stopper members have been proposed. Specifically, there are a flap type that rotates around a predetermined rotation axis and a thing that protrudes upward from the ground. Such a movable vehicle stop device operates by the action of an actuator such as a hydraulic cylinder or an air cylinder.

  However, each of the above conventional examples has the following problems. In other words, when a conventional flap-type car stop device is raised from the ground, or when the car stop device is buried and protrudes from the ground, no means for alerting is taken, so it walks without noticing. It may be an obstacle for pedestrians. In particular, when the illumination is dark at night or the like, a pedestrian may trip on the car stop device. Further, even when the car stopper is completely raised or protrudes from the ground, it may not be visible in a dark place, and has the same problem as described above. Furthermore, in the case of a car stopper device embedded in the ground, since there is almost no portion protruding from the ground in the embedded state, the pedestrian has no awareness of the vehicle stopper device. As a result, when the car stop device unexpectedly protrudes from the ground, if no means for alerting is taken, it may be possible that the car stop device is stumbled.

  An object of the present invention is to provide a car stop device that solves the above-mentioned problems, and in order to achieve the object, a movable car stop member, an illumination member mounted on the car stop member, and the car stop member The lighting member employs a means for emitting light in a predetermined color when the car stopper member is raised, when it is raised, when lowered, and when it is lowered.

The lighting member emits light in the first color when it is raised, emits light in the second color when it is raised, emits light in the third color when it is lowered, and is colored in the fourth color when it is lowered. It takes the means of emitting light.
Further, the first color is red.
Further, the second color is blue.
The first color and the third color are the same color.
Further, the first color, the second color, the third color, and the fourth color are all the same color.
Further, the lighting member employs a means of emitting light in a blinking state at least when the vehicle stopper member is raised or lowered.

The blinking cycle is variable.
The car stop device according to any one of claims 1 to 8, wherein the lighting member is continuously lit in at least one of a rise completion state or a descent completion state of the car stop member.
Moreover, the said illumination member has taken the means that it is mounted | worn with the side surface of the said vehicle stop member.
Moreover, the said illumination member has taken the means that the top part vicinity of the said vehicle stop member is mounted | worn.

The car stopper member is housed in a predetermined casing and can be moved up and down through a predetermined opening formed in the casing, and a predetermined light is passed through the gap between the car stopper member and the opening in the casing. The auxiliary illumination member that radiates the light is disposed.
Further, the auxiliary illumination member takes a means of emitting white light.
Further, the auxiliary illumination member employs a means of emitting light by power from an independent battery or a commercial power source.

  According to the present invention, since the lighting is mounted on the car stop device and the lighting state of the light is changed according to the operation state, the presence of the car stop device can be easily recognized by a pedestrian or the like. Have

  Next, an embodiment of the present invention will be described with reference to the drawings.

[Overview]
As shown in FIG. 1, the car stopper device 1 according to the present embodiment includes a cylindrical car stopper member 3, an illumination member 5 provided in a top region of the car stopper member 3, and a lifting mechanism that moves the car stopper member 3 up and down. 7, a casing 9 that houses the elevating mechanism 7, and an auxiliary illumination member 11 disposed in the casing 9.

[Car stop member]
As described above, the car stopper member 3 has a cylindrical shape and is erected in the vertical direction. The car stopper member 3 is made of a metal such as aluminum or iron in order to ensure strength as a car stopper. The interior of the vehicle stop member 3 is hollow, and electrical wiring for supplying power to the illumination means 5 described later is inserted.

  Note that the shape of the car stopper member 3 is not limited to a cylindrical shape, and may be a quadrangular prism shape or other polygonal column shape. Furthermore, it may be conical or pyramidal. As for the material, plastic or the like can be used as long as a predetermined strength can be secured. Further, an anti-slip member (not shown) may be installed on the upper surface of the car stopper member 3 so that a pedestrian or the like does not slip even when walking on the car stopper member 3.

[Lighting member]
Next, the illumination member 5 will be described. The illuminating member 5 is mounted so as to be fitted in a recess (not shown) formed in the top region of the car stopper member 3. For this reason, the illuminating member 5 has a ring shape, and forms a continuous circumferential surface when the lighting member 5 is attached to the car stopper member 3. However, the lighting member 5 may have various shapes other than the ring shape. For example, the lighting member 5 may have a structure in which a number of simple rectangular lighting members are mounted around the vehicle stopper member 3. Further, the illumination member 5 may be disposed on the upper surface of the car stopper member 3. This is because the presence of the movable vehicle stop member 3 can be more clearly shown by the surroundings.

  The illumination member 5 according to the present embodiment includes a translucent member exposed to the outside and a light emitting member (not shown) housed inside the translucent member. The translucent member is made of a transparent plastic material and can emit light from the light emitting member to the outside. The material of the translucent member is not limited to plastic, and any material can be used as long as it can transmit light. Moreover, it does not necessarily need to be transparent, and a translucent material may be used. In addition, the light transmitting member may have a function of irregularly reflecting light so that a small number of light emitting members can emit light over a wide range. This is the same as the technique used for a turn indicator (winker) or a stop lamp (stop lamp) of an automobile.

  A control means (not shown) is connected to the light emitting member in the illumination member 5, and the operation of the light emitting member is controlled by this control means. Specifically, the light emitting member is controlled to be extinguished when the vehicle stopper member 3 is housed in the casing (lowering completion state). On the other hand, when the vehicle stop member 3 is raised, it emits red light. At this time, red light emission may be blinked. Further, when the vehicle stop member 3 is completely raised and stopped (upward completion state), it is controlled so as to emit blue light. Also in this case, blue light emission may be blinked. Further, when the car stop member 3 is lowered, it is controlled to emit red light in the same manner as when it is raised. In order to enable such an operation, the light emitting member is equipped with a light emitting diode capable of emitting red light and blue light. The lighting member 5 may emit light with a predetermined color when the descent of the vehicle stop member 3 is completed. By doing in this way, the section of a car stop member can be shown more clearly.

[Elevating mechanism]
Next, the lifting mechanism 7 will be described. The raising / lowering mechanism 7 is for raising / lowering the vehicle stop member 3, and in this embodiment, an air cylinder is used as an example. The air cylinder is supplied with pressurized air from a pump (not shown) through a pressure pipe so that the vehicle stopper can be pushed upward or stored in a casing which will be described later. However, the lifting mechanism is not limited to an air cylinder, and may be a hydraulic cylinder, an electric motor, or the like. Moreover, it is not limited to raising / lowering a vehicle stop member directly with an air cylinder, For example, you may make it raise / lower using a pantograph mechanism, an air cylinder, an electric motor, etc.

[casing]
Next, the casing 9 will be described. The casing 9 is embedded in the ground and accommodates the vehicle stopper member 3, the lifting mechanism 7, and the like. For this reason, only the upper end surface of the casing 9 is exposed from the ground 13. The casing 9 of the present embodiment has a hollow quadrangular prism shape, and a circular opening 15 is formed on the upper end surface. The car stopper 3 is moved up and down through the circular opening 15. The casing 9 is fixed in the ground by a stay 17 installed on the outer surface. The stay may have not only a function of fixing the casing in the ground but also a leveling function. This leveling function is a function of leveling the upper surface of the casing. Specifically, the bolt can be screwed into a nut attached to the stay, and the tip of the bolt can be brought into contact with the installation surface for horizontal adjustment.

[Auxiliary lighting member]
Next, the auxiliary illumination member 11 will be described. The auxiliary illumination member 11 is for irradiating light to the outside through a gap between the circular opening 15 of the casing 9 and the car stopper member 3. This is for making a pedestrian or the like recognize the presence of the car stop device 1. The auxiliary illumination member 11 of the present embodiment is a light emitting diode (LED) that is directed from the inner wall of the casing 9 to the gap, and has a white color. However, the color is not limited to white and may be the same color as the illumination member 5. Further, the auxiliary illumination member 11 is not limited to the LED, and a circular or rod-shaped fluorescent lamp may be installed in the casing 9. The auxiliary illumination member 11 is always turned on at night, and is controlled to be turned off during the daytime. For this reason, an optical sensor (not shown) is connected to the auxiliary illumination means 11, and the daytime and the nighttime are discriminated by a signal from the optical sensor. In addition to a normal commercial power supply, an independent battery may be used to supply power to the auxiliary lighting member 11. By using an independent battery in this way, installation work of the car stopper is facilitated, and daily maintenance is also facilitated. However, since the battery is consumed, it is desirable to connect charging means such as a solar battery. In addition, since the vehicle stop member is provided with illumination means, it is not always necessary to install auxiliary illumination means.

[Construction]
Next, a construction example of the car stopper device 1 according to this embodiment will be described. First, a hole having a predetermined depth is excavated at a place where the car stopper device 1 is desired to be installed. The depth of the hole is such that at least the upper end surface of the casing 9 is the same as the ground. Then, a foundation is formed with concrete or the like at the bottom of the hole. The stay 17 of the casing 9 is fixed to this foundation. Thereafter, the soil is backfilled around the casing 9. Then, spread asphalt or the like on the ground as necessary. The above is a simple construction method, but there is also a construction method aimed at higher strength. This forms a housing for storing the car stopper in concrete in advance in the ground. Next, the car stopper is disposed in the housing. At this time, the leveling function added to the stay 17 is adjusted so that the upper surface of the casing 9 becomes horizontal. When the adjustment is completed, non-shrinkable concrete is poured between the inner surface of the housing and the outer surface of the casing and solidified. As a result, the casing is firmly fixed. In addition, asphalt laying is the same as the simple construction method.

[Action]
Next, the effect | action of the vehicle stop apparatus 1 which concerns on this embodiment is demonstrated based on FIG.2 and FIG.4. First, in the storage state (lowering completion state) as shown in FIG. 2A, the light emitting member of the illumination member 5 is not lit, but the auxiliary illumination member 11 emits light. For this reason, white light leaks to the outside through the gap between the vehicle stopper 3 and the circular opening 15. Thereby, the lane marking of the car stop member 3 can be clearly displayed, and the pedestrian can easily recognize the presence of the car stop device 1. However, you may make it light the illumination member 5 in the completion state of descent without providing the auxiliary illumination member 11. This is because the illumination member 5 is installed at the top of the vehicle stop member 3 and exhibits the same function as the auxiliary illumination member 11. In addition, in the state where the lowering of the car stopper member 3 is completed, the upper surface of the car stopper member 3 is set to be substantially flush with the other parts. For this reason, even if a pedestrian walks in the vicinity of the car stop device 1 or a wheelchair runs, it does not become an obstacle.

  Next, the elevating mechanism 7 is actuated to raise the vehicle stopper 3 (at the time of ascent). At that time, the illumination member 5 blinks with red light. As a result, a pedestrian walking in the vicinity or a driver of a traveling vehicle can easily notice the rise of the vehicle stop member 3. In particular, it can be said that the illumination member 5 blinking in red moves upward as the car stop member 3 rises, so that it is easy to call the viewer's attention. For this reason, it is effectively prevented that a pedestrian or a running vehicle comes into contact with the rising vehicle stop member 3. Further, at this time, white light from the auxiliary illumination member 11 leaks to the outside from the gap formed at the base of the car stopper member 3 to clearly indicate the base position of the car stopper member 3.

  Next, the elevating mechanism 7 is stopped, and the vehicle stopper 3 is in the highest protruding state (upward completion state). At this time, the illumination member 5 is lit in blue to notify the nearby pedestrian and driver of the presence of the car stop device 1. Instead of flashing red when it is rising, it is always lit in blue because once the car stop member 3 stops in a protruding state, it can be easily seen by pedestrians and drivers compared to when it is rising Because. Further, since the blue color makes the viewer feel intuitively safe, the stop state of the car stopper member 3 can be intuitively recognized.

  Further, when the vehicle stop member 3 descends (descent), it blinks in red light as when it rises. As a result, it is possible to notify the pedestrian or driver that the vehicle stop member 3 is changing, that is, in operation, and call attention. When the vehicle stopper 3 is completely stored in the casing 9, the illumination member 5 is turned off.

  As described above, the lighting state of the illumination member 5 is changed in accordance with the state of the vehicle stop member 3 in the vehicle stop device 1 of the present embodiment. For this reason, the pedestrian and driver | operator of the vicinity can recognize the state of the vehicle stop member 3 easily. In addition, by controlling the light such as red and blue and the lighting state thereof, it is possible to alert the pedestrian and driver in the vicinity. Here, the “lighting state” mainly indicates a continuous lighting state or a blinking state, but the present invention is not limited to this. That is, an application in which the blinking period is variable is also conceivable. This is because if the blinking cycle is made too early, the viewer may feel uncomfortable, and if it is too late, the alert function may be lost. As a method of changing the blinking cycle, it is conceivable to make the blinking fast while the vehicle stop member 3 is raised, and blink more slowly while descending. In addition, the color of the light used with the above-mentioned illumination member 5 is an example, and you may make it use another luminescent color. For example, orange or pink can be used as a color instead of red, and green or the like can be used as a color instead of blue. Furthermore, it may be devised such that red is used when the vehicle stopper 3 is raised and yellow is used when the vehicle stopper 3 is lowered. Moreover, you may make it make an illumination member light-emit with the same color in all the states of the vehicle stop member 5. FIG. By doing so, it is possible to manufacture the car stop device at a lower cost compared to the case where light can be emitted in different colors.

[Modification]
Next, a modification of the present embodiment will be described with reference to FIG. In the car stopper device 31 according to this modified example, the car stopper member 33 has a prismatic shape. And the U-shaped illumination member 35 is each provided in the side surface of a longitudinal direction both ends. However, the shape of the illumination member 35 is not limited to the U-shape, and may be provided over the entire circumference of the top portion of the car stopper member 33. By adopting such a shape, it is easier to attract the attention of surrounding pedestrians and drivers. The operation of the illumination member 35 of the vehicle stop member 33 also flashes red when it is raised, lights blue when it protrudes, and flashes red when it is lowered. Moreover, although the raising / lowering mechanism of the said modification is not shown in figure, it arrange | positions two air cylinders at intervals in the longitudinal direction. However, the present invention is not limited to this, and may be moved up and down by one air cylinder using a pantograph mechanism.

  FIG. 4 is a table showing an example of the lighting state of the illumination member in each state of the vehicle stopper member. In the pattern 1, the light is extinguished when the descent is completed, blinks red when it rises, lights blue when it rises, and blinks red when it descends. Pattern 2 is different from Pattern 1 in that it is lit white even when the descent is completed. Pattern 3 is different from pattern 2 in that the blinking cycle when rising is faster than when falling. The pattern 4 is different from the pattern 2 in that it is lit in blue in the descent completion state. The pattern 5 is different from the pattern 3 in that it is lit in blue in the descent completion state. The pattern 6 is lit in blue in all states. In the lighting state as described above, blue indicates mainly a safe state, red indicates a state that requires attention, fast flashing indicates a state that requires advanced attention, and slow flashing indicates a low level of attention. Indicates when necessary.

  Further, the present invention is not limited to the above-described general lift type car stop device, but can be applied to a so-called flap type car stop device.

  It can be used for a parking stop or a car stop device installed in a place where other vehicles pass.
