Description

Application of Article 30, Paragraph 2 of the Patent Law On June 15, 2017, Sanyo Road Industry Co., Ltd. sold a horizontal swivel opening / closing circuit breaker to Ryu Road Co., Ltd.

The present invention relates to a horizontal swivel opening / closing type barrier provided in a road, a passageway of an important facility, or the like.

At the entrances of important facilities such as highways and airports, there are barriers that are normally closed and opened only when necessary. Many barriers are simple, such as raising and lowering a bar, but these days, as a measure to prevent vehicles from entering due to terrorism, barricades are used at the entrances of important facilities such as highways and airports. There is a demand for a large openable and closable barrier that also serves as a barricade.

As a large-scale barrier that also serves as a barricade, there is a gate device disclosed in Patent Document 1. This gate device is mainly composed of a support and a traffic control member. The traffic control member is composed of a tubular fitting body to be fitted to the support column and a steel pipe extending in the horizontal direction provided in the tubular fitting body. The total load of the traffic restricting member is supported by the sliding guide portion provided on the upper part of the column and the side surface of the column. Therefore, the traffic control member is supported so as to be able to swivel along the sliding guide portion.

Japanese Unexamined Patent Publication No. 2002-121716

In such a gate device of Patent Document 1, as the length of the steel pipe attached to the traffic control member becomes longer, a force is applied to the sliding guide portion provided on the support column which is a fulcrum by the principle of leverage. Therefore, when the traffic restricting member is rotated, the friction at that location becomes large, and it requires a great deal of labor to manually rotate the traffic restricting member.

The present invention has been made in view of the problems in the prior art, and provides a large-sized barrier that can be easily opened and closed by easily turning a member that restricts passage even by human power.

In order to achieve the above object, the present invention comprises at least the following configurations or carries out procedures. In the following description, reference numerals and the like shown in the drawings may be added to facilitate understanding of the present invention, but each component of the present invention is limited to those shown in the drawings.

Hereinafter, each embodiment of the present invention will be specifically described with reference to the drawings. It should be noted that the embodiments described below are merely specific examples for carrying out the present invention, and do not limit the interpretation of the present invention.

FIG. 1 is a perspective view of a barrier 100 according to an embodiment of the present invention. The breaker 100 includes a support column 110 extending in the vertical direction, a cutoff bar 130 for restricting the passage of vehicles and the like, a rotary support device 120 having a side plate 123 for supporting the cutoff bar 130, and a support column 110 and a rotary support tool. It is equipped with a tensioning tool 140 that binds the 120 together. FIG. 2 is an enlarged front view of the support column 110 side of the barrier 100 according to the embodiment of the present invention. The support column 110 has a flange portion 111 around the support column 110, and a friction reducing member 112 is provided on the flange portion 111. The first base plate 121 of the rotation support 120 is placed on the friction reducing member 112. The first base plate 121 slides and turns on the friction reducing member 112, so that the blocking bar 130 can turn around the support column 110 as a fulcrum. The barrier 100 of the present invention is provided at the entrance of a road or an important facility for vehicle traffic regulation, regulates the traffic of the vehicle, and also serves as a barricade.

The stanchion 110 is fixed so as to extend vertically to the foundation concrete under the ground. The support column 110 has a cylindrical shape and has an outer diameter of about 150 mm to 200 mm. The material is made of steel, and has sufficient strength to stably support the rotary support 120 and the cutoff bar 130.

The support column 110 is provided with a flange portion 111, and a friction reducing member 112 is fixed on the flange portion 111. For the friction reducing member 112, a disk of MC nylon (registered trademark), which is an engineering plastic (referring to a plastic having a heat resistance of 100 ° C. or higher, a strength of 50 MPa or higher, and a flexural modulus of 2.4 GPa or higher), is used. ing. This member has self-lubricating properties and does not require grease or the like unlike metal bearings. Moreover, since it has excellent wear resistance, it does not easily wear. Therefore, it is not necessary to inject a lubricant such as grease on a regular basis, and maintenance-free operation can be achieved. In addition, since it does not use grease or the like, it does not get dirty easily. Not limited to MC nylon (registered trademark), other engineering plastics may be used as long as they have appropriate strength and self-lubricating property. For example, a polyamide resin or a resin such as polyacetal or polytetrafluoroethylene may be used.

Further, although maintenance is required, a metal bearing may be used for the friction reducing member 112. Metal bearings have features such as high dimensional stability and excellent heat resistance, so either one may be selected according to the situation.

A sliding member 126 is fitted in the gap between the support column 110 and the first through hole 121a. The sliding member 126 has a shape in which a long and thin copper plate is rounded according to the outer diameter of the support column 110. That is, it is shaped like a spring washer. When the sliding member 126 is included, it is possible to prevent the side surfaces of the support column 110 and the first through hole 121a from rubbing against each other, so that friction can be reduced.

The column upper plate 113 provided on the upper part of the column 110 is provided with a first locking portion 114. This is where one end of the tensioner 140 for binding the column 110 and the rotary support 120 is attached. The rotation support 120 is tilted toward the support column 110 by pulling the rotation support 120 toward the support column 110 by the tension tool 140. By tilting the rotary support 120 toward the support column 110, the side plate 123 naturally tilts toward the support column 110. The angle at which the rotary support 120 is tilted is in the range of 0.1 ° to 3.0 °. This depends on the inclination angle θ of the lower surface of the first base plate 121 of the rotation support 120, which will be described later. Further, the support column upper plate 113 is configured to rotate in accordance with the rotation of the cutoff bar 130.

The tensioning tool 140 is for tilting the rotary support 120 by binding the column 110 and the rotary support 120 and pulling the rotary support 120 toward the column. When the rotary support 120 is tilted, the lower surface of the first base plate 121 and the friction reducing member 112 come into contact with each other on the surface. In this case, since the weight of the cutoff bar 130 is dispersed on the surface of the friction reducing member 112, friction does not occur at a specific location, so that the cutoff bar 130 can be easily swiveled. In this embodiment, the tension tool 140 uses a turnbuckle. With a turnbuckle, you can easily change the tension. Therefore, even when the tension of the turnbuckle changes due to a change in temperature, it can be easily adjusted.

The blocking bar 130 is a member for restricting the passage of vehicles and the like. The thickness of the cutoff bar 130 is a cylindrical shape of about 150 mm to 200 mm, and is welded to the side plate 123. The number of blocking bars 130 is four, two on the top and two on the bottom, and a truss bar 131 is installed between the blocking bars 130. Due to this structure, the blocking bar 130 has high strength. The number of blocking bars 130 may be two, one on the top and one on the bottom, and a truss bar 131 may be installed between them. The strength is lower than that of four blocking bars 130, but the weight is lighter, so that the blocking bars 130 can be easily swiveled. A reflective material is attached to the surface of the blocking bar 130 in order to improve visibility at night. This makes it possible to prevent a collision with the barrier 100 at night.

The cutoff bar 130 is made of aluminum. Aluminum is preferable because it is a light metal but has high strength and impact resistance. A light and high-strength material such as reinforced plastic may be used.

The cutoff bar 130 includes a drop bar 133 on the drop bar cradle 132. In this method, if a hole is provided in the ground such as a road in advance and a drop bar 133 is inserted at the hole, the blocking bar 130 can be fixed at that position.

FIG. 3 is a diagram of the rotation support 120 of the breaker 100 according to the embodiment of the present invention. The rotation support 120 is a member for making the cutoff bar 130 swivel, and includes a first base plate 121, a second base plate 122, a side plate 123, a connecting plate 124, and a second locking portion 125. It is composed of.

The first foundation plate 121 has a first through hole 121a, and the first through hole 121a is inserted through the support column 110, and the first foundation plate 121 is placed on the friction reducing member 112. .. The lower surface of the first base plate 121 has an inclination angle θ of 0.1 ° to 3.0 ° with respect to the line S orthogonal to the side plate 123. The most preferable inclination angle θ is 0.5 °. The inclination angle θ is provided by changing the thickness of the first base plate 121. However, the present invention is not limited to this, and the first base plate 121 may be provided by tilting it by an inclination angle θ and fixing it to the side plate 123 or the connecting plate 124. By providing the tilt angle θ on the lower surface of the first base plate 121, when the rotary support 120 is pulled by the tensioning tool 140, the rotary support 120 can be tilted toward the support column 110 by the tilt angle θ. ..

When the rotary support 120 is pulled by the tensioning tool 140 and the blocking bar 130 is tilted, the center of gravity of the weight of the blocking bar 130 approaches the support column 110 side. In that case, the force with which the tensioning tool 140 pulls the blocking bar 130 toward the support column 110 is reduced. Therefore, since the burden on the tensioning tool 140 is reduced, the failure of the tensioning tool 140 can be reduced. Further, since the blocking bar 130 faces diagonally upward, there is an effect that the tip of the blocking bar 130 does not hang down. It should be noted that the inclination angle θ is effective if it is inclined even at 0.1 °. However, if it is tilted by 3.0 ° or more, it comes into contact with the support column 110 and the side surface of the first through hole 121a, and the friction at that portion increases, so that it becomes difficult to rotate. Therefore, the inclination angle θ is preferably in the range of 0.1 to 3.0 °.

The first through hole 121a has a tapered shape, and the upper surface side hole diameter L1 is wider than the lower surface side hole diameter L2. As a result, when the sliding member 126 is fitted in the gap between the support column 110 and the first through hole 121a, even if the gap between the support column 110 and the lower surface side hole disappears, the support column 110 and the upper surface side hole can be provided. A gap can be secured. If the gap is secured, the rotation support 120 can be tilted toward the support column 110 by the tension tool 140.

The second base plate 122 has a second through hole 122a, and the second through hole 122a is inserted into the support column 110. The second through hole 122a has an elliptical shape, and the direction in which the blocking bar 130 extends has a major axis. With this shape, since there is a space for tilting the rotary support 120 by the tension tool 140, the rotary support 120 can be tilted toward the support column 110. Further, since the rotation support 120 is tilted, the support column 110 and the side surface of the second through hole 122a do not come into contact with each other because of the space, so that friction does not occur when the blocking bar 130 is swiveled.

The side plate 123 is a plate for supporting the cutoff bar 130, and the cutoff bar 130 is fixed to the side plate 123 by welding. Further, the side plate 123 connects the first base plate 121 and the second base plate 122.

The connecting plate 124 is a plate that connects the first foundation plate 121 and the second foundation plate 122. The rotary support 120 has high strength due to the structure in which the side plate 123 and the connecting plate 124 are connected so as to sandwich the first base plate 121 and the second base plate 122.

The second locking portion 125 is a place to attach the other end of the tensioning tool 140. One end of the tensioning tool 140 is attached to the first locking portion 114. The second locking portion 125 is provided in parallel at two locations on the upper portion of the second base plate 122. The second locking portion 125 has a dogleg-shaped shape and is provided with a plurality of holes that allow the position where the other end of the tensioning tool 140 is attached to be changed. The tension of the tensioning tool 140 changes depending on which hole the tensioning tool 140 is attached to. Therefore, an appropriate tension can be maintained by attaching the tensioning tool 140 to an appropriate hole.

FIG. 4 is a front view when two breakers 100 according to the embodiment of the present invention are installed. If the road is wide, two barriers 100 can be installed so as to face each other. In this case, it is preferable to provide the barrier 134 with the bar 134. This is because the strength can be increased by closing the bar 134 with the breaker 100 closed.

As described above, according to the barrier 100 according to the embodiment of the present invention, the barrier bar 130 for restricting traffic can be easily turned in the horizontal direction by human power.

Next, the barrier 200 provided with the receiving column 150 for accommodating the barrier bar 130 of the barrier 100 according to the embodiment of the present invention will be described with reference to FIG.

The receiving column 150 stores the blocking bar 130 when the blocking bar 130 is open. Further, the receiving column 150 is installed in a place that does not obstruct the passage, that is, on the side of the road or the like.

The receiving column 150 is fixed so as to extend vertically to the foundation concrete under the ground, and has a receiving pedestal 151 for holding the blocking bar 130 and a pin fastener 152 for locking the blocking bar 130. have. The receiving column 150 has a cylindrical shape and has an outer diameter of about 150 mm to 200 mm. The material is steel, and the blocking bar 130 can be stably stored.

A slide roller 135 is provided at the lower portion of the tip of the cutoff bar 130. Since the cutoff bar 130 can be mounted on the pedestal 151 by the slide roller 135, the cutoff bar 130 can be easily stored in the pedestal 151. The slide roller 135 has a structure that fits into a recessed portion of the pedestal. Due to this structure, the stored blocking bar 130 does not come off naturally.

The cutoff bar 130 includes pins 136. By inserting the pin 136 into the pin fastener 152, the cutoff bar 130 can be received and fixed to the support column 150. Further, after inserting the pin 136, the key can be closed with a padlock or the like. As a result, it is possible to prevent the blocking bar 130 from being opened and closed without permission due to mischief or the like. When the blocking bar 130 is received and stored in the support column 150, the weight of the blocking bar 130 is supported to some extent. Therefore, the burden on the tensioning tool 140 and the like can be reduced, and as a result, the failure of the breaker 200 can be reduced.

As described above, if the receiving column 150 is provided, the blocking bar 130 can be stored in the receiving column 150 and locked with a padlock or the like, so that the blocking bar 130 can be turned freely by mischief or the like. Can be prevented. Further, since the weight of the cutoff bar 130 can be dispersed, the failure of the breaker 200 can be reduced.

FIG. 6 is a diagram of a barrier 300 in which an extension pole 137 is attached to a barrier bar 130 of the barrier 100 according to the embodiment of the present invention.

The cutoff bar 130 has an extension pole 137 that can be taken in and out in the horizontal direction. The extension poles 137 are two, and the tips thereof are connected by a rod. The length of the stretch pole 137 can be adjusted by sliding it. Therefore, if the barrier 100 is installed in a state where the barrier bar 130 is a little shorter than the road width, that is, a car cannot pass through, but a space for people and bicycles can pass through, the barrier 100 can be installed by simply inserting and removing the extension pole 137. It is possible to control the passage of. In this case, it is useful because employees working in a facility or the like can pass through without turning the cutoff bar 130.

It is also possible to install the receiving column 150 for the barrier 300 to which the extension pole 137 is attached.

As described above, if the barrier 300 to which the extension pole 137 is attached is used, when an employee or the like passes through, the passage is possible only by inserting and removing the extension pole 137 without turning the cutoff bar 130.

The breaker according to the present invention can easily open and close the breaker by simply turning the break bar in the horizontal direction even by human power. Therefore, it is useful because the time and effort for opening and closing the cutoff bar can be reduced.
