Description

[0001] Safety railing device for drop prevention [

The present invention relates to a handrail device capable of preventing fall.

Generally, safety bridges are installed on bridges, verandahs and rooftops of high-rise buildings to prevent falls.

The currently installed railings are classified into standardized low height rails and high height rails for preventing walks.

These rails are fixedly installed, so they can be crossed artificially, especially low railings can be easily passed.

Here, low railings are often installed on bridges and verandas of high-rise buildings.

However, since low railings are installed in bridges with high transmission frequency, it is difficult to prevent the transmission if the people are willing to move over easily.

In other words, until now, there is no physical preventive measure to prevent the transmission, and it relies on the post-measures such as the system call, CCTV, and announcement.

In order to prevent this, when the railing is raised, there is a problem that the view and the aesthetic appearance are deteriorated.

Korean Registered Patent No. 10-0633242 (September 30, 2006)

The preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which the technical parts already known will be omitted or compressed for the sake of brevity.

1 to 5, the safety guardrail device 1 for fall prevention according to the embodiment of the present invention includes a lever portion 11 and a rotation portion 12.

The lever portions 11 are provided on both sides of the handrail 21 of the railblock 2 and include a lower body 111, an upper body 112, an elastic body 113, a fixing piece 114, A fixed core 115, and a hinge portion 116. As shown in Fig.

The lower body 111 is formed in a rectangular box shape having an approximately open top and is provided with a pair and fixed to both upper ends of the handrail 21 of the railing 2.

The upper body 112 is formed in a rectangular box shape having a substantially lower opening so as to correspond to the lower body 111 and to have the lower end of the upper body 112 closely contact with the upper end of the lower body 111 .

A pair of elastic members 113 are provided, and a coil spring or the like is used. The elastic members 113 are disposed inside the upper body 112 and the lower body 111. A description thereof will be described later.

The fixing pieces 114 are formed in a substantially washer-like shape and are provided with two pairs, one of which is in close contact with the bottom of the lower body 111 and the other of which is in close contact with the ceiling of the upper body 112, respectively.

At this time, the fixing piece 114 disposed on the upper body 112 is engaged with the upper end of the elastic body 113, and the fixing piece 114 disposed on the lower body 111 is engaged with the lower end of the elastic body 113.

As a result, the elastic body 113 is restrained by the fixing piece 114.

One of the fixed cores 115 is formed in a substantially round bar shape and one of the fixed cores 115 is inserted into the ceiling of the upper body 112 through the fixing pieces 114 disposed on the upper body 112, And the other is inserted into the bottom of the lower body 111 through the fixing piece 114 disposed on the lower body 111 and is inserted into the fixing piece 114 and the lower body 111 Respectively.

The fixing member 114 is fixed to the upper body 112 and the lower body 111 by the fixing core 115 so that the elastic body 113 is inserted into the upper body 112 and the lower body 111, And the upper and lower ends of the elastic body 113 can be constrained to the upper body 112 and the lower body 111, respectively.

The hinge portion 116 connects the upper body 112 and the lower body 111 and is provided with a pair and is disposed on the outer side of the upper body 112 and the lower body 111, And is fixed.

Accordingly, the upper body 112 swings toward the side where the pedestrian moves, with the hinge portion 116 as the center.

At this time, the hinge portion 116 can operate at a rotation angle within approximately 20 to 40 degrees.

Thus, the upper body 112 also has a limited swing angle within approximately 20 to 40 degrees.

Further, when the external force is removed after the upper body 112 swings, the upper body 112 is restored to the original position by the elastic body 113.

If the hinge portion 116 rotates about 90 degrees, the upper body 112 also swings about 90 degrees.

When the upper body 112 swings about 90 degrees, the elastic body 113 is also bent to about 90 degrees because an excessive force is applied to the elastic body 113, so that the elastic body 113 is not restored to its original shape, .

When the elastic body 113 is deformed, the upper body 112 can not be restored to its original position, thereby restricting the rotation angle of the hinge portion 116.

In addition, since the transporter may sandwich the foot between the roller portion 122 and the handrail 21 to be described later, the swing angle of the upper body 112 is restricted in order to prevent this.

The technique for limiting the rotation angle of the hinge portion 116 is well known or well known in the art, and a detailed description thereof will be omitted.

The rotating portion 12 is provided at the upper end of the lever portion 11 and includes a bracket 121, a roller portion 122, a cover 123, a bearing 124 and a fixed shaft 125.

The brackets 121 are provided with a pair of front and rear surfaces, and are formed in a substantially "┛" or "┗" shape. The brackets 121 are formed with a screw hole 121a. Respectively.

The roller portion 122 is cylindrical in shape with an approximately open end, and the length corresponds to the distance between the brackets 121, and is disposed between the brackets 121.

The cover 123 is provided in a pair, is formed in a substantially washer-like shape, and is fixed to both ends of the roller portion 122, respectively.

The bearings 124 are provided with a pair and are fitted to the covers 123, respectively.

At this time, the bearing 124 may be a one-way bearing that is rotatable only in one direction, that is, rotatable only on the bearing side.

A description thereof will be described later.

Here, the one-way bearing is known or well known, and a detailed description thereof will be omitted.

The fixed shaft 125 is provided with a pair and is formed in a substantially bolt or screw shape and is screwed to the screw hole 121a of the bracket 121 through the bearing 124. [

Accordingly, the bearing 124 is constrained between the fixed shaft 125 and the bracket 121 and rotates.

That is, when the roller portion 122 rotates, the cover 123 rotates together, and the cover 123 rotates by the bearing 124 with a small frictional force. Therefore, the roller portion 122 rotates very well even when a small force is applied.

The rotation unit 12 may be configured such that the bearing 124 is inserted into the cover 123 and the bracket 121 is coupled to the upper body 112 after the fixing shaft 125, the bearing 124, and the bracket 121 are engaged, As shown in Fig.

When the rotation unit 12 is detached, it can be easily separated by reversing the above-described coupling order.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an operating state of a safety guardrail railing device 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

When the transporter tries to cross the railing over the roller portion 122, the roller portion 122 is rotated and the hand slips.

In other words, the roller portion 122 is rotated to slip the hand, thereby preventing the transporter from exceeding the rail.

If the transporter tries to pass the railing while gripping the roller portion 122 tightly, the roller portion 122 is pulled toward the transporter while the upper body 112 swings toward the transporter.

The roller portion 122 is pulled toward the transmitter and the roller portion 122 is rotated so that the transmitter can prevent the roller portion 122 from overcoming the rail portion.

In other words, it is possible to prevent the action to be overrun by primarily moving the center of the body backward by dispersing the force, and to prevent the action to move over by causing the roller portion 122 to rotate and miss the hand from the roller portion 122 .

Also, if the transporter rises up against the roller portion 122, the bearing 124 will only rotate toward the transporter, so that the transporter slips downward into the railing, preventing the transporter from slipping out of the rail have.

Then, the rotary part 12 and the upper body 112 are restored to their original positions by the elastic force of the elastic body 113.

Accordingly, the present invention can prevent the safety of the falling objects by preventing the children from raising the railing by preventing the falling of the railing by preventing the railing from overturning the railing when the transporter intends to pass the railing by artificially .

In describing the present invention described above, even though the embodiments are different, the same reference numerals are used for the same configurations, and the description thereof may be omitted as necessary.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Shall not be construed as being understood. Therefore, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
