Description

[Detailed description of the invention] (Industrial application field) This invention is applicable to cylindrical horizontal frame members such as caps, upper and lower horizontal frames, etc. for handrails installed on balconies, balconies, stairs, rooftops, etc. This invention relates to a connection device with a stand.

(Prior art and its problems) Conventionally, for example, when connecting a cylindrical cap and a similar cylindrical stand, the upper end surface of the stand was shaped into a curved surface corresponding to the outer surface of the cylindrical cap. While the curved end surface is engaged with the lower surface of the Kasagi, the upper end of the long bolt for tightening the brace installed on the base is inserted into the brace. The cap and the stand were connected by protruding from bolt holes provided in the cap and by screwing nuts into the protruding ends from inside the cap and tightening them. However, according to this, since the cap is not a so-called split type, it is difficult to insert and tighten the nut inside the cap, and furthermore, each bolt for tightening the braces becomes long. There was a problem with high costs.

(Technical means for solving the problem) The present invention solves the above problem, and the technical means is to form an opening 5 on the lower side or the upper side of the horizontal frame member 2. A cover member 6 is provided over the entire length of the horizontal frame member, and is formed to cover the opening 5 and has the same length as the horizontal frame member 2, and has a cover member 6 that extends over the entire length of the horizontal frame member. It is characterized in that the front end surface of the stand 4 is brought into contact with the opening 5 and fixed with a screw 11, and the cover member 6 is attached to the opening 5.

(Example) Next, an example of the present invention will be described based on the drawings.

Figure 1 shows a handrail installed on a balcony. In this figure, 1 is a post installed on the weir wall S, 2 is a cap, 3 is a lower horizontal frame, 4 is a cap 2, This is a stand placed between the 3 lower horizontal frames.

The cap 2 has a cylindrical shape made of extruded aluminum, and an opening 5 is provided on the lower side of the cap 2 over the entire length of the cap, as shown in FIG. A cover member 6 having an arcuate cross section is attached to the cover member 6 . This cover member 6 is made of an extruded aluminum material, has the same length as the cap 2, and has a width wider than the opening width of the opening 5, so as to completely cover the opening 5. The outer surface of the cover member 6 is curved with the same curvature as the outer circumferential surface of the cap 2, and is arranged flush with the outer circumferential surface of the cap 2. The lower horizontal frame 3 is a cylindrical piece made of extruded aluminum with a diameter smaller than that of the Kasagi 2. The lower horizontal frame 3 has an opening 7 along its entire length on its upper side. 7 is also covered with a cover member 8 having an arcuate cross section, and this cover member 8 is formed to have the same length as the lower horizontal frame 3 and to be wider than the opening 7. Each brace 4 is a cylindrical piece made of extruded aluminum with a diameter smaller than that of the lower horizontal frame 3, and has a bis pocket 9 formed along its central axis as shown in FIGS. 2 and 3. The upper end surface 4a and lower end surface 4b of each stand 4 are cut into curved shapes corresponding to the outer surfaces of the cover members 6 and 8, respectively.

FIG. 2 shows the connection device between the cap 2 and the stand 4, and the connection device between the lower horizontal frame 3 and the stand 4.

When connecting the cap 2 and the stand 4, the upper end surface 4a of the stand 4, which has been cut into a predetermined curved shape, is brought into contact with a predetermined portion of the outer surface of the cover member 6. Insert the screw 11 into the screw pocket 9 of the stand 4 through the screw insertion hole 10 provided in the cover member 6.
This cover member 6 is screwed into the cover member 6 and tightened.
Each frame 4 is connected and fixed at right angles to the frame. Then, with the inner surface of the cover member 6 facing the opening 5 of the cap 2, both ends of the cover member 6 are connected to the engagement steps 12 and 1 formed on the outer surface of both side edges of the opening 5.
2, and screw the screws 13 into each of these engaging portions and tighten them to fix the cover member 6 to the cap 2, thereby connecting the cap 2 and each stand 4. There is.

Further, the connection between the lower horizontal frame 3 and the braces 4 is similar to the above case, and the lower end surface 4b of each brace 4 is brought into contact with a required part of the outer surface of the cover member 8. The screw insertion hole 1 provided in this cover member 8
By screwing the screws 15 into the screw pockets 9 of the stand 4 and tightening them, the stand 4 is connected and fixed at right angles to the cover member 8, and both end surfaces of the cover member 8 are connected to the outer surfaces of both side edges of the opening 7. The screws 17 may be screwed into each of these engagement portions to tighten them.

In addition, in the actual manufacturing of the handrail, the cover member 6 on the Kasagi 2 side, the required number of braces 4... and the lower horizontal frame 3 are required.
The side cover members 8 are integrally connected to each other, and the cover members 6 and 8 are attached to the Kasagi 2 and the lower horizontal frame 3 almost simultaneously, respectively. do.

FIG. 4 shows another embodiment of a connection device for connecting the Kasagi 2 to the stand 4. According to this, a cover member 6 to which a plurality of stand 4 are respectively attached with screws 11 is attached. When fixing to the Kasagi 2, insert the screw 19 through the screw insertion hole 18 provided in the widthwise center of the cover member 6, and screw it into the screw hole (not shown) in the horizontal support wall 20 inside the Kasagi 2. By inserting and tightening, the cover member 6 is fixed to the cap 2. In this case, screw 1
The insertion position of 9 is midway between the adjacent latches 4.

In the above embodiments, only the cylindrical horizontal frame members and braces have been described, but these horizontal frame members and braces are not limited to cylindrical shapes, but may also be rectangular tube shapes, and the braces may be hollow. It is not limited to
It may be solid.

(Effects of the invention) The connecting device of the invention is such that the cover member is screwed to a required part of the outer surface of the cover member in contact with the end face of the brace, and the cover member is attached to the opening of the horizontal frame member. Therefore, even though the horizontal frame member is not a so-called split type but a pure cylindrical shape, screwing the brace can be easily performed on the outside of the horizontal frame member, and therefore the connection work is easy. Since the cover member is formed to completely cover the opening of the horizontal frame member, the appearance of the horizontal frame member is not spoiled, and furthermore, the cover member is formed to completely cover the opening of the horizontal frame member. Since there is no need to use through bolts, the work becomes easier and costs are reduced.
