Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a connection device for connecting railings and horizontal frame members such as caps, top and bottom horizontal frames, etc. in handrails installed on balconies, balconies, stairs, rooftops, etc. .

(Prior art and its problems) Conventionally, for example, when connecting a cylindrical cap and a stand, the upper end surface of the stand is cut into a curved shape corresponding to the outer surface of the cylindrical cap, While this curved end surface was engaged with the lower surface of the cap, a long bolt for tightening the braces installed upright on the base was inserted into the brace, and the upper end of this bolt was attached to the cap. The cap was protruded from the bolt hole, and a nut was screwed onto the protruding end from the inside of the cap and tightened, thereby connecting the cap and the stand. Since it is not shaped, it is difficult to insert and tighten the nut inside the cap, and furthermore, the bolt for tightening the brace is long, resulting in high costs.

(Technical Means for Solving the Problems) The present invention solves the above-mentioned problems. is provided along the entire length of the horizontal frame member, and has a bottom wall 6a that closes the opening of the recess 5, and is formed to fit into the recess 5 over its entire length. A pedestal mounting frame 6 having a substantially U-shaped cross section is provided, and the tip end surface 4a of each pedestal 4 is placed against the outer surface of the bottom wall 6a of the pedestal mounting frame 6 and fixed with screws. It is characterized by being fitted into the recessed portion 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. Figure 2 shows a connecting device between the cap 2 and the stand 4 as horizontal frame members, as well as the lower horizontal frame 3 as the horizontal frame member.
This figure shows a connecting device between the frame and the stand 4. The cap 2 has a cylindrical shape made of extruded aluminum. On the outer surface of the cap 2, a recess 5 having a U-shaped cross section is provided along the entire length of the cap 2. A U-shaped brace mounting frame 6 is fitted therein. This brace mounting frame 6 is also made of extruded aluminum, and is composed of a bottom wall portion 6a that closes the opening of the recessed portion 5, and side wall portions 6b, 6b protruding from both side edges of these. 6a
The outer surface of the mounting frame 6 is formed in an arc shape so as to be flush with the outer circumferential surface of the cap 2 when the mounting frame 6 is fitted into the recessed portion 5 . Further, a concave portion 7 having a U-shaped cross section is provided on the outer side surface of the lower horizontal frame 3 along the entire length of the lower horizontal frame 3, and within this concave portion 7 is a brace mounting frame 8 which also has a U-shaped cross section. are fitted together. This brace mounting frame 8 is also made of extruded aluminum, and includes a bottom wall portion 8a having an outer surface flush with the outer peripheral surface of the lower horizontal frame 3, and a bottom wall portion 8a having an outer surface flush with the outer peripheral surface of the lower horizontal frame 3, Projected side wall portion 8
b, 8b. Furthermore, each stand 4
The upper end surface 4a is formed in a shape corresponding to the arcuate outer surface of the frame 6 (that is, the shape corresponds to the outer peripheral surface of the cap 2), and the lower end surface 4b of the frame 4 is formed in a shape corresponding to the outer peripheral surface of the frame 6. It is formed in a shape corresponding to the arcuate outer surface (or the outer peripheral surface of the lower horizontal frame 3). This stand 4 is also cylindrical and made of extruded aluminum, and has a bis pocket 9 formed along its central axis.

Therefore, when connecting the cap 2 and the stand 4, first, the upper end surface 4a of each stand 4 is placed against the outer surface of the bottom wall 6a of the stand mounting frame 6, and the bottom wall After screwing and tightening the screw 10 into the bis pocket 9 of the stand 4 from the inner surface side of the stand 6a and thus attaching the stand 4 to the mounting frame 6 in advance, the stand installation frame 6 is inserted into the concave portion 5 of the cap 2. Fits inside. Then, screw insertion holes (not shown) are provided in the bottom wall portion 6a of the brace mounting frame 6 at required locations, and the screws 11 are inserted through the screw insertion holes into the bottom wall portion 5a of the recessed portion 5. By screwing into a threaded screw hole (not shown), the frame mounting frame 6 is securely fixed so that it does not come off from the recessed part 5.

The connection between the lower horizontal frame 3 and the braces 4 is exactly the same as in the above case, and the lower end surface 4b of each brace 4 is brought into contact with the outer surface of the bottom wall portion 8a of the brace attachment frame 8, and the bottom After screwing and tightening the screw 12 into the bis pocket 9 of the stand 4 from the inner side of the wall 8a, and thus attaching the stand 4 to the mounting frame 8, the stand mounting frame 8 is It fits into the recessed part 7 of the lower horizontal frame 3. The brace attachment frame 8 is also fitted and fixed to the bottom wall portion 7a of the recessed portion 7 of the lower horizontal frame 3 using screws not shown.

In the connecting device shown in Fig. 2, the frame mounting frame 6,
Although screws 11 were used to securely fix 8 in the fitted state to the recesses 5 and 7, FIG. 4 shows a connection in which the brace mounting frame can be securely fixed without using such screws 11 This is an example of the device. That is, according to FIG. 4, the concave portion 5' of the cap 2 is provided with fitting concave portions 13, 13 at both ends of the bottom wall portion 5a', and on the other hand, the concave portions 13, 13 for fitting are provided at both ends of the bottom wall portion 5a'. Fitting protrusions 14, 14 protruding outward are provided at the tips of the side walls 6b', 6b'. The portions 14, 14 are engaged with the grooved portions 13, 13, respectively, so that the frame 6' is securely fixed.

(Effects of the invention) According to the connecting device of the present invention, a brace mounting frame that can be fitted into a recess provided with a horizontal frame member is provided, and each brace is attached to the outer surface of the bottom wall of the brace mounting frame. Since the end face of the child is abutted and fixed with screws, and the brace mounting frame is fitted into the recessed part, even if the horizontal frame member is not a so-called split type but a pure cylindrical shape, A bottom wall in which the bracing can be easily screwed on outside the horizontal frame member, so that the connection work can be performed accurately and quickly, and the bracing mounting frame closes the opening of the recessed part. Because it has a part, the appearance of the horizontal frame member is not spoiled,
Furthermore, since no elongated through bolts are used, the work becomes easier and costs are reduced.
