 An extremely narrow opening is provided between the fixed handrail of the balcony and the building, or between adjacent fixed handrails. The opening of the narrow structure is used as an evacuation interval in an emergency or in an emergency, or has a structure that gives the flexible property of a fixed handrail. However, even the narrow opening may cause a fall accident such as an infant, which is dangerous. Also, small items may fall, which is very dangerous. It should be noted that, although temporary obturators are occasionally found, they do not have sufficient structure and strength, and the above-mentioned drawbacks have not yet been solved.

[0003]

[Problems to be solved by the device]

 From the above situation, in order to prevent a fall accident from the opening of the fixed handrail of the veranda, the adjacent fixed handrails should be connected to each other via a separate handrail (so-called intermediate handrail). It is necessary to have a configuration in which the opening of Furthermore, if the connection is not flexible, there is a problem that it may cause a breakage accident in the event of an earthquake, and there is a problem with the secondary handrail due to damage to the fixed handrail and intermediate handrail. A disaster may occur.

The object of the present invention is to solve the above-mentioned problems, and the opening is closed by a flexible structure to prevent a fall accident and there is no fear of a breakage accident. Moreover, it is to obtain the middle balustrade of the expansion structure of the veranda which is most suitable for the handrail of the earthquake-resistant structure.

[0005]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention adopts the following configuration.

[0006] That is, the veranda's fall-prevention expansion handrail according to the present invention is a veranda's fall-prevention expansion handrail including a fixed handrail having an opening and an intermediate handrail installed at the opening of the fixed handrail. Then, insert a nesting insert piece provided on the side frame of the intermediate handrail into the upper and lower frames in the opening of the fixed handrail, and cope with expansion and contraction of the opening through the nesting insert piece. It has a different structure.

[0007] In addition, an expansion handrail for preventing the fall of a veranda having another structure is vertically installed on an opening provided between adjacent fixed handrails on the veranda and a pair of columns vertically erected on both sides of the opening. And a pair of left and right side frames fitted into the fitting recess, and upper and lower frames provided on the pair of side frames, and vertically provided between the pair of side frames and the upper and lower frames. A plurality of standing pieces, and an intermediate handrail including an engaging piece provided with a spring provided on each of the pair of side frames.

[0008]

[Action]

The operation (use) of the present invention will be described below. First, in the example shown in FIG. 1 and FIG. 2, during normal use, the intermediate handrail is fitted into the fitting recess and slid below the upper part for mounting. As a result, the opening is closed and the intermediate handrail is flexibly connected by the elastic member. Therefore, when opening the opening, it suffices to slide the attached intermediate handrail and pull it up, which is very easy and easy to use.

Further, in the case of the intermediate handrail having the insertable insert piece shown in FIG. 3, as a general rule, it is provided when the fixed handrail is constructed. That is, after constructing the fixed handrail on one side, one insertion piece of the intermediate handrail is inserted into the openings of the upper and lower frames, respectively. Then, the other insert piece of this intermediate handrail is constructed by inserting the openings of the upper and lower frames of the other fixed handrail. In this example, since the insert pieces are inserted in the upper and lower frames of the left and right fixed handrails in a nested manner, the opening of the fixed handrail is closed and, in the event of an earthquake, Since the flexible property is secured between the intermediate handrails, it has a structure that can sufficiently withstand earthquake resistance. Of course, it is also possible to provide an intermediate handrail in this example after constructing the fixed handrail.
