Summary of the Invention

Problems to be Solved by the Invention

[0004] As described above, the electric gate device installed at the entrance and exit of a parking lot has generally been of a type that uses a metal chain as a closing member. It is made strong, and the stretched chain has a large mass and hardness. Therefore, when it is opened and closed (raised and lowered) at high speed, the landing sound on the road surface is large and dangerous, and it is necessary to control the opening and closing speed to a certain extent. Also, as shown in Patent Document 1, for the protection of the base body, a metal connecting fitting is used for connecting the metal chain, which is an opening and closing member, to the movable part of the base body mechanism. When an overload occurs, the connecting fitting breaks to protect the base body. However, there are problems that it is dangerous to the human body and damage occurs to the vehicle. Furthermore, because the chains installed on the road surface are very hard and can damage the road when vehicles pass over them, it is common practice to create grooves in the road surface to drop the chains into. In addition, the base unit is large in volume and heavy in mass, making transportation and installation work a large-scale undertaking, requiring specialized contractors and qualified electricians. As a result, installing these electric chain gate devices is expensive, and repairs also require contractors to visit the site. To solve the above problems, the present invention aims to provide a small, lightweight, and easily transportable, installable, and maintainable electric rope gate device. [Means for solving the problem]

[0005] The first and second electric rope gate devices according to the present invention are electric rope gate devices installed at the entrance and exit of a parking lot to restrict the entry and exit of vehicles by tightening and loosening a rope, and are characterized in that they include a rope stretched between the entrance and exit of the parking lot, a rope support installed at one end of the entrance and exit of the parking lot and incorporating a rope slackening means that electrically performs the raising, tightening, lowering, and loosening operations of the rope, and a control box that controls the raising, tightening, lowering, and loosening of the rope, the control of the control box is performed by remote equipment, and the other end of the rope at the entrance and exit of the parking lot is fixedly connected to either a fixed support installed opposite the rope support or to the wall of a building.

[0006] A third electric rope gate device according to the present invention is an electric rope gate device installed at the entrance and exit of a parking lot to restrict the entry and exit of vehicles by tightening and loosening a rope, comprising a rope stretched between the entrance and exit of the parking lot, rope posts installed at one end and the other end of the parking lot entrance and exit, each containing a rope slackening mechanism that electrically controls the raising, tightening, lowering, and loosening of the rope, and a control box that controls the raising, tightening, lowering, and loosening of the rope, wherein the control box is controlled by a remote device, and the rope slackening mechanisms built into both rope posts operate synchronously.

[0007] Furthermore, the rope slackening means used in the first to third electric rope gate devices according to the present invention is composed of a mechanism consisting of an elongated base, a motor attached to one end of the base for raising / tensioning and lowering / loosening the rope, a drive pulley connected to the output shaft of the motor, a driven pulley attached to the other end of the base, a belt stretched between the drive pulley and the driven pulley, and a guide rope fastened and fixed to a predetermined position on the belt. Position detectors are attached to the base near the drive pulley and the driven pulley, respectively, and the detection members of the position detectors are attached to the belt at predetermined positions opposite to the fixing position of the guide rope, and are moved synchronously between the position detectors with the movement of the belt during raising / tensioning and lowering / loosening operations, and the base as a whole is removable from the opening at the top of the support column.

[0008] Furthermore, the first to third electric rope gate devices according to the present invention are characterized by the use of magnetic connecting members that can be attached and detached with a low load (5 kg or more) at the connection points between the marker rope and the guide rope, and by the unification of the electrical and electronic components constituting the electric rope gate device to low-voltage drive. [Effects of the Invention]

[0009] The electric rope gate device of the present invention uses a fiber rope instead of the metal chain used in conventional electric gate devices. Because the fiber rope itself is lightweight and soft, there is almost no noise when it comes into contact with the road surface when opening and closing at high speed, making it unobtrusive even when entering or exiting the parking lot at night.

[0010] Furthermore, since vehicles can pass over the rope as it descends and touches the road surface without damaging it, there is no need for a groove to drop the rope into.

[0011] Furthermore, because fiber ropes are lightweight, the electric rope gate device itself, including the mechanism that provides tension, can be made lighter and more compact. In addition, since the entire device is driven by low voltage, no electrician's license is required, making transportation and installation easy.

[0012] The mechanism, which serves as the relaxation device, can be removed from the opening at the top of the support column, along with the base, and sent to the service center for maintenance or repair. [Brief explanation of the drawing]

[Figure 6] This diagram shows the mechanism inserted through the opening at the top of the support column. [Figure 7] This diagram shows the connection between the control box and the support column. [Figure 8] This diagram shows the operation of each part in a time chart. [Modes for carrying out the invention]

[0014] The embodiments for carrying out the present invention will be described below with reference to Figures 1 to 8. The first and second electric rope gate devices 1 according to the present invention are, as described in claim 1, a rope 5 stretched between the entrance and exit of a parking lot, a rope support column 2 installed at one end of the parking lot entrance and exit and incorporating rope relaxation means for electrically raising, tensioning, lowering, and slackening the rope 5, and a control box 6 for controlling the raising, tensioning, lowering, and slackening of the rope 5. The control of the control box 6 is performed by a remote control device 6a. Also, the other end side of the rope 5 at the parking lot entrance and exit is fixedly connected to either a fixed support column 3 installed at a position facing the rope support column 2 or a building wall surface 4. Thereby, the cost can be suppressed by using only one rope support column 2 incorporating rope relaxation means. (See FIGS. 1, 2, and 7)

[0015] The third electric rope gate device 1 according to the present invention is, as described in claim 2, a rope 5 stretched between the entrance and exit of a parking lot, a control box 6 for controlling the raising, tensioning, lowering, and slackening of the rope 5, with rope support columns 2 having the same structure installed at positions facing the rope support columns 2 installed at one end and the other end of the parking lot entrance and exit and incorporating rope relaxation means for electrically raising, tensioning, lowering, and slackening the rope 5. The control of the control box 6 is performed by a remote control device 6a. Also, the rope relaxation means incorporated in both rope support columns 2 operate synchronously and the frontage can be effectively utilized. (See FIGS. 3 and 7)

[0016] The mechanism part 8 that performs the rope slackening means is composed of a geared motor 10 for performing the tensioning and slackening operations of the guide rope 5a attached to the elongated base 9 as described in claim 3, a drive pulley 11 connected to the output shaft of the geared motor 10, a driven pulley 12 attached to the other end of the base 9 by a driven pulley attachment member 2b, a belt 13 hung between the drive pulley 11 and the driven pulley 12, and the guide rope 5a tightly fixed by a guide rope fixture 13a such as a binding band at a predetermined position of the belt 13, specifically at a position near the driven pulley when the slackening of the guide rope 5a is completed. Further, position detectors 14 and 15 are respectively attached to the base 9 near the drive pulley 11 and the driven pulley 12, and the detection members 16 of the position detectors 14 and 15 are attached at a predetermined position relative to the fixed position of the guide rope 5a on the belt 13, specifically at the position detected by the position detector 14 on the drive pulley 11 side when the slackening of the guide rope 5a is completed. This detection member 16 moves synchronously between the position detectors 14 and 15 along with the movement of the belt 13 during the tensioning and slackening operations of the guide rope 5a. Moreover, as described in claim 6, the outer ring part 12a of the driven pulley has a drum shape and a width 2 to 6 times that of the drive pulley 11, so as to prevent the guide rope 5a from falling off the driven pulley 12. (See Fig. 4)

[0017] Furthermore, the mechanism part 8, which is the rope slackening means built into the rope support 2, is removably integrated with the base 9 from the upper opening 2a of the rope support 2 as described in claim 4. Maintenance of the lightweight mechanism part 8 can be easily performed, and only this mechanism part 8 can be sent to the manufacturer. Note that 2b indicates the upper cover. (See Figs. 5 and 6)

[0018] The rope 5 stretched between the entrance and exit of the parking lot is composed of a guide rope 5a and a sign rope 5b connected to this guide rope 5a by a magnet connection member 5c as described in claim 5, and can be easily detached under an overload of about 5 Kg or more, so it can safely protect the human body and vehicles. (See Figs. 1 to 3 and Fig. 6)

[0019] As described in claim 7, the control box 6 has a power cut-off and recovery circuit that, after the rope 5 has finished rising and tensioning, cuts off the rising / tensioning signal from the output terminal 6b with a delay after the position detector 15 has detected the position, and then restores power when there is a signal for the rope 5 to descend and loosen. In the event that the detection member 16 does not react to the position detector 14 on the drive pulley 11 side, overheating of the geared motor 10 can be prevented. Figure 7 shows the output terminal 6b, power input terminal 6c, and AC adapter 7. Figure 8 is a time chart showing the operation. (See Figures 1-4, 7, and 8)

[0020] Furthermore, an operation indicator light 2c is provided near the top of the rope support 2 as described in claim 8, and the operation indicator light 2c lights up only when the rope 5 descends and the position detector 14 on the drive pulley 11 side outputs a detection signal, thereby ensuring that the rope 5 is lowered (see Figures 1-6 and 8).

[0021] The operation indicator light 2c is fixed to the rope support 2 by the operation indicator light mounting panel 9a, as described in claim 9. This panel also serves as the fixing means for the rope support 2 and the base 9, thus preserving the aesthetic appearance of the rope support 2 without drilling unnecessary mounting holes (see Figures 4 and 6).

[0022] As described in claim 10, the electric rope gate device 1 according to the present invention uses only low-voltage electrical equipment, and therefore can be installed without the need for an electrician's license. [Explanation of symbols]
