Description

Technical Field [0001] The present invention relates to safety rails having a handrail capable of controlling direction,

The present invention relates to a safety rail that is installed on a bridge, a roadway, or a delivery side. In particular, it is possible to adjust the direction of the railroad rail up or down or to the left or right so that the driver or pedestrian can see the railroad rail better. The present invention relates to a security guardrail having a handlebar which can be adjusted in one direction so that the effect of widening the view can be seen and the decorative plate can be arranged in various ways to improve the beauty of the guardrail.

Generally, a safety guardrail installed on a car or a bridge side protects a pedestrian from a vehicle, or a safety guardrail installed on a footbridge performs a function of preventing a pedestrian from falling.

Therefore, the safety railing should be good visibility for the driver of the vehicle because it becomes the boundary barrier which distinguishes the roadway from the roadway. In other words, the driver must be able to grasp the installation location of the safety railing in the distance to help safe driving. Especially when the weather is bad, such as at night or fog, it can be well recognized to reduce accidents.

On the other hand, the safety railing is a facility that affects the aesthetics of the installation place, and therefore, a method of expressing various designs is required.

As a background of the present invention proposed for such a solution, there is Korean Registered Patent Registration No. 10-0732916 (safety light emitting rail for the road). It consists of a metallic post placed at regular intervals on the ground along the road and a transparent polycarbonate pipe made of high strength plastic. It is vertically spaced between two adjacent posts and secured to the corresponding posts at both ends. A plurality of guard bars opposing the support channels, a plurality of LED lamps arranged at predetermined intervals in the substrate on the strips, the plurality of LED lamps being accommodated in the interior of the guard bars by slidingly coupling the substrates to the support channels, A sealing means for sealing both ends of the guard bar, and an illuminance sensor for detecting the illuminance of the surroundings and automatically turning on the LED lamp when the sensed illumination is lower than a predetermined value and automatically turning off the LED lamp when the sensed illumination is higher than a predetermined value.

Therefore, the above background technology enables the driver and the pedestrian to recognize the railway at all times by lighting the lamp regardless of the weather, such as the nighttime, snow, and fog, thereby posing a fear of safety accidents due to railroad collision and / It has an advantage that it can be minimized.

However, the background art requires a power supply device in addition to an electrical circuit configuration of the LED lamp, which raises a problem that the installation cost increases.

Korean Registered Patent No. 10-0732916 (Safety light emitting railing for roads) Korean Registered Patent Registration No. 10-0681735 (Safety Rail for Bridges with Fall Protection) Korean Registered Patent No. 10-1342135 (Floating Type Safety Railing)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

≪ Embodiment 1 >

The safety railing 10 according to the first embodiment of the present invention is capable of adjusting the vertical railing 18 to be laterally described (angle). By thus allowing the driver to adjust the direction of the vertical railing 18 from side to side, the driver of the vehicle approaching from afar can not only look at the front of the vertical railing 18 but also see the stereoscopic visual effect while passing through the vertical railing 18, And will start operating.

As shown in Figs. 1 to 4, the railroad girder 12 is provided with a railing support 14 at regular intervals. The railing support 14 may be made of a steel material having an H-section and installed on a concrete foundation.

A vertical rail support bar 16 is provided at the upper part and the lower part of the railing support 14 in the lateral direction (transverse direction perpendicular to the railing support). The vertical rail support bar 16 can be made of a steel material having a square pipe cross section or a steel material having an H-shaped cross section.

As shown in FIGS. 2A and 2B, the vertical railing support bar 16 is provided with a vertical railing 18 via a tilting bracket 20 for adjusting the left and right direction. The vertical railings 18 are arranged at regular intervals along the longitudinal direction of the railing. The vertical railing 18 may comprise a body made of synthetic wood, a foam (urethane foam), a composite material or the like.

As shown in FIGS. 3A and 4, the tilting bracket 20 for adjusting the lateral direction is fixed to the front surface of the vertical railbanger support bar 16 at one end and fixed to the rear surface of the vertical railbear 18, So that it is possible to adjust the front side direction of the front side of the main body side by an arbitrary angle. The tilting bracket 20 for adjusting the lateral direction includes a fixed end bracket 201 whose one end is fastened to the vertical rail support bar 16 with a bolt 17 and a hinge pin 202 And a rotating stage bracket 203 hingedly connected to the vertical railing 18 by a bolt 19.

Therefore, the vertical railing 18 can be adjusted laterally (angle) with the hinge pin 202 of the tilting bracket 20 for adjusting the left and right direction as a rotation center. For example, the vertical railing 18 can be adjusted to the right as shown in FIG. 2B. The fixing force of the vertical balancer 18 after the direction adjustment is obtained by tightening a nut (not shown) fastened to the hinge pin 202 by screwing to forcefully contact the contact surface between the fixed end bracket 201 and the rotating end bracket 203 .

Thus, the safety guard 10 of the first embodiment can adjust the left and right direction of the vertical railing 18 so that when the front of the vertical railing 18 is oriented at a certain angle? As shown in FIGS. 2B and 3B, The time when the driver or the pedestrian looks at the vertical railing 18 is clearly recognized as being widened in a plane. In this case, when a reflector (not shown) is attached to the front side of the vertical railing 18, a large amount of reflection of the vehicle light is received by the driver or the pedestrian in the distance. In case of rain or rain, And the safe driving is planned.

The binding insert core 22 is made of an aluminum extruded material in this embodiment. The binding insert core 22 has a rectangular center 221 for insertion of the head of the bolt 19, a guide groove 222 for communicating the position of the bolt 19 by communicating with the square weights 221, A decorative plate coupling groove 223 is formed at one side of the vertical railing 18 for end coupling with the decorative plate 30.

The vertical railing 18 may further include an ornamental plate 30 which is fitted through the ornamental plate engaging groove 223 of the binding insert core 22 as shown in Figs. 1, 3A, and 4. The decorative plate 30 has a decorative plate engaging protrusion 301 at one side or both sides for engaging with the decorative plate engaging groove 223 of the binding insert core 22. The decorative plate 30 is configured in the same rectangular shape in the present embodiment, but is not limited to this shape.

For example, as shown in FIG. 1, it is possible to arrange the decorative plates 30 disposed between neighboring vertical side rails 18 and 18 so as to follow the S-shaped trajectory at different levels, can do.
