Description

  The present invention relates to a handrail for a balcony or a veranda. More specifically, the present invention relates to a joint member for joining and fixing a column and a lateral member constituting the handrail.

  In particular, the present invention is a joint that forms a top rail by attaching a square bar-shaped horizontal beam between columns, or forms a horizontal louver-type handrail by mounting a horizontal beam-shaped louver lattice material or the like to the column. A horizontal rail or a horizontal rail-shaped louver lattice material joined or fixed by the joint member provides a handrail having a design that is transverse to the column.

  Further, the present invention provides a top rail by attaching a slender square bar-shaped side rail to a slender, substantially flat bar-shaped strut with an extremely small finding surface, or a slender side to the substantially flat-bar-shaped strut. The present invention provides a joint member for forming a horizontal louver-type handrail by attaching louver lattice members or the like having a cross shape to a plurality of stages.

  Conventionally, there are various inventions for the joint structure for fixing the handrail post and the cross rail. However, if the handrail component is an aluminum extrusion, it can only be assembled by welding or caulking, and it has sufficient strength. In addition to being unable to ensure, there is a problem that repair becomes difficult if the welding or caulking is removed.

  Thus, in order to solve the above-mentioned problems, there is an invention of Japanese Patent No. 3561799 (Patent Document 1) by the same applicant.

  The invention of Patent Document 1 is divided into a front member and a rear member of a tubular crosspiece made of a saddle material that is parallel to the handrail between pillars of a handrail post in a handrail such as a veranda made of an aluminum mold material, An intermediate rib is provided at the front member split position, and a thickened portion for receiving a screw is formed at the center of the intermediate rib so that it is fixed to the front surface of the column via a mounting plate with screws. A fitting structure corresponding to the combined structure is provided at the division position of the rear member, and the rear member cut to the width between the columns corresponding to the front member fixed to the column is fitted to the front member. The gist is to integrate.

  And the invention of Patent Document 1 divides the handrail crosspiece into two parts to be a front member and a rear member, and both are integrated later by a fitting means, so that a handrail crosspiece made of an aluminum mold is used. The material can be fixed to the column with screws. Therefore, it does not break from the portion like a welded or crimped one, and even if it is broken, it can be replaced by simply recombining with a screw.

  In addition, the invention of Patent Document 1 has a simple configuration, can be completed in the factory in advance, can reduce the number of man-hours on site, is not only economically effective, but also has various designs. In addition to being able to cope with the appearance, there are also design interesting things such as it is not possible to see if there is a cutting part on the column or a cutting part on the side rail at first glance. It has characteristics, and the effect obtained by the implementation of the present invention is extremely great.

  However, in the invention of the above-mentioned Patent Document 1, the mounting plate serving as the joint member of the crosspiece is configured to be screwed so that the center is crossed to the front surface of the column by two tapping screws with respect to the column. Furthermore, there is a drawback that the screwing strength of the mounting plate to the support column is not so strong.

That is, in the invention of Patent Document 1, the finding dimension which is the front surface of the handrail support column is relatively thin, 20 to 30 mm, and the mounting plate is screwed onto the front surface of the thin handrail support column with two tapping screws. When worn and fixed, the pitch between the tapping screws can only be small. Therefore, when a vertical force is applied to the crosspieces supported by the mounting plate, it is applied as a rotational force between the pitches of the mounting plate that is too small, so the mounting strength of the mounting plate is not very robust. It was.

  Furthermore, the present invention can form a top rail by attaching a slender square bar-shaped side rail to a slender, substantially flat bar-shaped column having an extremely small finding surface, or a slender, substantially flat bar-shaped column. A joint member for forming a horizontal louver-type handrail by attaching louver lattice materials or the like having a horizontal beam shape to a plurality of stages is provided, and the present invention having these effects has great industrial applicability. have.

It is the front view which shows the top rail assembled by implementation of this invention, and sectional drawing. FIG. 5 is a front view and a cross-sectional view showing a lateral louver type handrail for a balcony assembled according to an embodiment of the present invention. It is a perspective explanatory view explaining the joint method of the support | pillar member and horizontal beam member by the joint member of this invention. It is sectional drawing explaining the shape of the joint part assembled by FIG. It is a perspective view explaining the shape of the adhering member used in FIG. It is a perspective view explaining the other example of a shape of an adhering member.
