Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a handrail device provided towards the outside of a building.

In recent years, buildings have become taller and taller, and as a result, the number of accidents involving falls from high places such as buildings and buildings has gradually increased. For this reason, efforts are currently being made to prevent falls, such as by setting off-limits areas in dangerous areas.

However, in conventional housing complexes, iron fences are usually installed on the outside of balconies, and the railings are used for hanging futons and laundry to dry on the upper edge, or as play areas for growing children. There are many examples. At times like this, accidents often occur, such as when putting in or taking out a futon, or when young children accidentally fall while playing, or when they develop a fear of heights and fall. It is a well-known fact that these accidents immediately lead to fatal accidents because they occur at high places, and that the number of accidents is likely to increase in the future.

These accidents lead to a truly sad situation in which the living spaces of high-rise buildings, which should be comfortable, suddenly bring about the greatest misfortune in one's life.

Therefore, it is natural that we have to take measures to prevent accidents from occurring between builders, building owners, and building beneficiaries, but in the face of such serious social problems, there are still no technological means to solve them. Currently, it is not adopted.

In view of the above circumstances, the present invention has been developed as a means of preventing falls from buildings, in which when a certain force is applied to the top of a handrail on a balcony, etc., the handrail rotates only in one direction, that is, inside the building. The purpose is to provide a new handrail equipped with a reversing prevention device that prevents it from rotating on the outside, in order to prevent accidents involving falls from high-rise buildings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 is a front cross-sectional view of the one-way rotating safety handrail of the present invention.

A fixed shaft 2 is attached to a bearing plate 3 at the center of the inner peripheral space of the cylinder l in the longitudinal direction.
A cam guide plate 4 (see Fig. 2) is fixed to the fixed shaft 2, and a cam 5 that can slide on the inner circumferential surface of the cylinder l is attached to the cam guide plate by tightening bolts. 7 etc. The cam guide.

The plate 4 and the cam 5 are constructed by suspending a tension panel 8.

Note that the cylindrical body l indicates the surface of the safety handrail. The internal structure of the main handrail has been explained above, and the handrail is elongated in the longitudinal direction to increase the length of the handrail. Further, the joint 9 extends downward and is fixed as a holder 11 to an existing iron fence such as a bezel, so that it can be expanded and installed indefinitely depending on the length of the iron fence.

FIG. 2 is a side sectional view of the safety handrail of the present invention.

The safety handrail constructed as described above operates as follows.

The cylinder l, that is, the handrail, can rotate in the direction of the arrow as shown in Figure 2, and as long as the movement in the direction of the arrow continues, it will continue to rotate, and if it tries to rotate in the opposite direction of the arrow, The cam 6 in sliding contact with the cylindrical body 1 exerts a restoring force as a characteristic of a tension spring, and the cam 5 strengthens its contact with the inner peripheral surface of the cylindrical body 1. At this time, the pressure resistance between the inner circumferential surface of the cylinder l and the tip of the cam 5 gradually increases, and the rotational movement of the cylinder stops. Furthermore, as the load increases, a pressure resistance force equivalent to the load is added, so that reverse rotational movement of the cylinder cannot occur. In other words, the cam clutch system of the present invention performs a braking function on the reverse rotation opening of the cylinder (hand fi1).

The safety feature of the present invention is that the rotation of the top of the handrail, that is, the outer circumference, is unidirectional, and when installed on the balcony of a high-rise building, even if force is applied to the handrail, the outside (
Because the handrail does not rotate toward the living space (such as the garden), it only rotates toward the living space such as an inner balcony, so there is no risk of falling even if human force is applied to the handrail, and therefore there is no risk of fatal accidents. effective.

For example, when we put our elbows on a handrail, dangle from it, put our feet on a protrusion, or put our weight on a handrail by putting our upper body on it, we all have the willpower not to fall due to our reflexes. If the center of gravity of your body moves inward even just a little, the handrail will rotate inward and you will never fall outward. Also, when taking in the dry weight, if you pinch the edge of the futon and pull it toward you, the handrail will rotate inward, so even young children can easily take in the futon without requiring much force.

Furthermore, in dangerous areas where suicides are likely to occur, the handrail of the present invention can be linked with a low-speed motor to continuously rotate at all times, which can be expected to be even more effective in preventing suicides.

Claims (1)

[Scope of Claims] A fixed shaft 2 is fixed to a bearing disc 8 at the center of the inner circumferential space of the cylindrical body l, and a cam guide disc 4 is fixed to the fixed shaft number. A cam 5 that can slide on the inner circumferential surface of the cylindrical body l is pivotally attached to the cam guide plate 4 via a lip 6 with bolts 7, etc., and between the cam guide plate 4 and the cam 5, A one-way rotating safety handrail characterized in that the cylindrical body 1 can rotate only in one direction by suspending a tension spring 8.
