Description

{SILENT MOTORIZED SAFETY BALUSTRADE}

The present invention relates to safety rails between a stage seat and an orchestra lift, and more particularly to a silent safety guardrail.

The safety railing is a type of lower machine of the stage apparatus. The safety guardrail 3 is positioned between the orchestra lift 1 and the audience seat 2 as shown in Fig. 1, and the fall from the audience seat 2 to the orchestra lift 1 And the safety guardrail 3 is usually fixed type, and there are a passive type and a transmission type. Motorized type is convenient for stage operation but fixed type or passive type may be used for operational problems.

Condition of orchestra safety railings

- Since the purpose of the orchestra railing is a safety rail that functions as a safe fence between the audience and the orchestra,

First, it must be safe.

Second, the noise during operation should not interfere with the performance of audiences.

Third, the audience should not be shaken when they lean or push.

Fourth, in order to install the bridge from the stage to the rail, the load of the bridge must be able to withstand the pushing down of the railing.

- In case of stationary type, it satisfies all four above because it is completely fixed to the concrete floor. To use the orchestra lift part as an additional seat, the audience should be able to enter or exit the orchestra lift. It should be repeated to make and attach. In addition, the audience is seated on the orchestra lift with fixed railings separated by seats.

- In case of passive mobile type, safety is not constant because it is a temporary installation method.

- The problem of the auditorium where the safety rail is installed as the electric type is that firstly, the railing frame is shaken and secondly, the operation noise is large.

2, which is a cross-sectional view taken along the line AA in Fig. 1, and Fig. 3, which is a cross-sectional view taken along the line BB in Fig. 1, a safety rail 3, which raises and lowers by electric rolling, between the orchestra lift 1 and the audience seat 2 Install,

The safety railing 3 includes a connection shaft 5 interlocked with the motor 4, a screw jack 6 for cutting the rotational force of the connection shaft 5 by the upward and downward force of the safety guardrail 3, And a screw 7 fixed to the safety guard 3 so as to raise and lower the safety guardrail 3 by the rotational force of the safety guardrail 6.

3 to 6, the safety railing frame 8 is provided at the lower end of the safety railing 3, the guide rails 9 are provided at the safety railing frame 8, Is raised and lowered on both ends of the flat wing portion 11 of the guide rail 10 of the H-shaped steel provided on the vertical side wall 12 at the end of the audience seat 2 where the orchestra lift 1 is installed. (15) is a driving part for the ascending and descending driving of the orchestra lift (1).

These existing transmission systems have two characteristics.

1) Guide system

- The guide is usually made of a guide rail (10) of H-shaped section, and the guide roller (9) is able to roll up and down on both ends of the wing section (11) of the H-shaped section. This is because the accuracy of the H-shaped steel of the guide rail 10 is not accurate and the strength is maintained when four to six or more of the guide rails 10 are installed instead of one at the time of installation. The guide rails 10 are separated from each other by the horizontal spacing of the guide rails 10 as shown in FIG. Therefore, the clearance between the wing portion 11 of the guide rail 10 and the guide roller 9 is about 1 to 3 mm. If there is no such clearance, a jamming phenomenon occurs in the vertical operation.

As shown in FIG. 7, the shaking phenomenon can not be prevented on the right and left of the safety guardrail 3 (front and rear in the seat 2).

2) Driving method

3 and 4, the raising and lowering power transmitting means is provided directly below the safety railing frame 8 in order to push up the safety railing frame 8, And a motor 4 for transmitting power for rotating the connecting shaft 5. The screw 6 is rotated to rotate the safety railing 3 The up and down operation effect is good, but the power transmission is transmitted to the multi-stage at a high speed, the power is transmitted to the bending as shown in FIG. 4, and the joint transmits the power in a universal form, . This lowers the concentration of the audience sitting in the audience. It is also a factor that the motor 4 rotates at a high speed.

 Conventional passenger safety barrier technology has been developed in such a way that the inner and outer support walls are spaced side by side on the audience slab between the audience slab and the orchestra stage as shown in Korean Utility Model Registration No. 20-0462592, However, since the inner and outer supporting walls are fixedly installed between the auditorium and the orchestra stage, there is a problem in that it is isolated when the auditorium is set up to the orchestra stage.

In order to control the height of the handrail, a technique of adjusting the height by changing the connecting angle between the horizontal bar and the vertical bar is known in Korean Patent Laid-Open Publication No. 10-2012-0105906, but the height is simply adjusted, I can not.

Although a stepped type stage functioning as a multi-step folding type is disclosed in Korean Patent Registration No. 10-0676915, a power transmission principle is shown in which a stage is folded and unfolded by a power transmission system through a driving roller shaft and a spur gear. It does not provide a technical principle of driving with noiselessness.

In addition, a stage facility using an orchestra assistant and a rotating stage is disclosed in Korean Utility Model Registration No. 20-0264991, but only the concept of ascending or descending the orchestral assistant is shown.

It is an object of the present invention to provide a low-noise electric safety railing without noise because the power of the motor is rolled up and down while being wound on a screw drum through a wire rather than through a rotary shaft.

Another object of the present invention is to provide a security railbearing safety rail frame, which comprises a horizontal ELM guide capable of horizontal movement, a horizontal ELM guide block of a horizontal ELM guide integrally provided with a vertical ELM guide block, Vertical LM Guide Lines and Horizontal LM Guides Even if the vertical rails of the vertical LM guide rails are tilted, the safety rails move up and down along several vertical LM guide rails vertically installed on the vertical sidewalls where the orchestra lifts and safety rails move. Noise railway safety railing which allows the rails to move up and down without vibration without pinching.

It is a further object of the present invention to provide a safety railing frame in which the upper end of a wire rope is fixed to a vertical side wall and a lower roller is provided at the lower end of the safety railing frame, In order to provide a low-noise electric safety railing that provides low noise even though it is powered, since the power of the wire rope is lowered and raised by lowering the pulling force of the wire rope in the process of passing through the roller and upper roller, will be.

Another object of the present invention is to provide a wire rope which is fixed to a vertical side wall and which is provided with a lower roller at the lower end of the safety rail frame and an upper roller at the upper end of the vertical wall, And the upper roller, it is able to withstand the load even when a separate bridge is installed between the stage and the safety railing without the need of a separate supporting force maintenance means, thereby providing a low-noise electric safety railing that provides safety I want to.

1) Guide system

- In the guide method, the safety rail 3 for the orchestra lift 1 is connected to the vertical side wall (not shown) by using the vertical horizontal LM guide 20, which is a combination of vertical and horizontal LM guides using precise guide rails instead of H- 8 to 14 as shown in FIG. 8 to FIG. 14 along the vertical ELM guide rail 21 provided on the floor panel 12, the safety railing 3 is elevated to perform a railing function, and when it is lowered, .

In this case, in order to prevent the vertical parallelism of several (usually four to six, but not limited to) vertical LM guide rails 21 from being correct, the horizontal LM guide means (horizontal LM guide block 23, 10 and the horizontal LM guide block 23 has a structure in which a horizontal LM guide rail 24 provided on the safety railing frame 8 of the safety railing 3 is added }. 10, the horizontal ELM guide rail 24, which moves in the horizontal ELM guide block 22 integrally coupled to the vertical ELM guide block 22 moving along the vertical ELM guide rail 21, Since the safety rail frame 8 is automatically adjusted in the horizontal and vertical positions by the vertical and horizontal distance errors, the safety rail frame 8 does not cause a jamming phenomenon during vertical operation, ) So that a quiet and quiet operation is possible.

In addition, since the vertical and horizontal LM guides 20 have a backlash of less than 0.1 mm in the vertical LM guide block and the horizontal LM guide block at a precision level, there is almost no swing of the safety guardrail frame, It can give a safety rail effect like a wall.

2) Driving method

The present invention employs a wire rope type screw drum driving unit 30 that drives the safety railing 3 to raise and lower the wire rope 36 by using the wire rope 36.
