The present invention relates to a stair handrail device, and more particularly, to guide the stairs by emitting light when it is dark, not only to enable quick and safe evacuation in case of emergency such as fire or power failure, but also to secure space for landing. The present invention relates to a sanitary stair handrail device having an antibacterial coating tube on the handle.

In general, the handrail device for stairs performed only functions of space decoration and safety measures. When the handrail device became dark due to a power failure due to a fire, etc., the fall of the stairs and railings could not be understood.

In order to improve this problem, a stair handrail device having a light emission guideline is formed to form a light emission guideline on a stair handrail device so that safe and rapid evacuation can be achieved.

The staircase handrail device having the light emission guideline includes a prefabricated staircase handrail device having the emergency light emission guideline of the Republic of Korea Patent No. 510870 presented by the applicant prior to the present application.

1 is a side view showing such a conventional step handrail device 20.

The conventional handrail device 20 has a problem that the support (21) is fixed to the landing (2) because the space of the landing (2) is narrowed to prevent the safe movement and evacuation.

Here, the landing (2) is a constant space formed between the stairs and the stairs (1) connecting the upper and lower floors of the building, it is important that a certain width or more must be secured for safe movement and evacuation in case of emergency.

The width of the landing 2 means the width from the finish line of the wall to the outer side of the prop of the handrail, and the fire law and the building code of Korea stipulate that the width should be more than 1200 mm.

In addition, the conventional handrail device 20 requires a separate coupler (22, 23, 24) in order to combine the components, the assembly and construction is complicated, there is a problem that the manufacturing cost is increased.

On the other hand, the handle 30 of the conventional handrail device 20 is to support the body by holding the hand up and down the stairs, if repeatedly used by many people there is a risk of infection in children or the elderly. . In particular, the risk of staircases in hospitals is higher.

The present invention is to solve the problems of the prior art as described above, its purpose is to secure the space of landing as much as possible, it is possible to move safely during the evacuation along the usual or light emission guidelines, and assembly and construction without a separate coupler In addition to simplicity, the handle is antibacterial to provide a hygienic stair handrail device.

In order to achieve the above object, the present invention, in the staircase handrail device which is installed on the stairs successively up and down around the landing that the direction of the stairs is switched, to promote the safety of pedestrians,

Support means installed in the support is fixed to the upper first staircase and the lower first staircase;

A handle means having a hand bar connected to an upper portion of the support and a hand bar connector connected to the hand bar by screwing the hand bar by coupling a coating tube to a shape deformation member formed of a bellows tube which interconnects the hand bar but is free of deformation; And
The handrail is coupled to the upper and lower portions of the support so as to be parallel to the hand bar, and the handrail has a handrail body installed at equal intervals, and the hand liver is coupled to the handrail body so as to be perpendicular to the ground, and has a bent portion at the top and the bottom. Provides a staircase handrail device comprising a guide means for vertically coupled to the handrail body, the cover means is fitted to the top of the handrail body and provided with a light emitting body on both sides to form a light emission guideline; do.
