Abstract

PROBLEM TO BE SOLVED: To provide a guide sign arm tree reinforcing metal fitting for improving the durability of a joint portion between a pillar of an arm tree type guide sign and an arm tree. SOLUTION: This is a pair of metal L-shaped and metal inverted L-shaped guide signs 1 and 2 attached to the left and right side surfaces of the pillar at the joint portion between the pillar and the arm tree forming the arm tree type guide sign. It has a blade portion 3 for supporting the arm tree, and holes 4 and 5 provided for fixing the pillar and the arm tree with a wood screw. [Selection diagram] Fig. 1

Description

The present invention relates to a reinforcing metal fitting for a guide sign arm.

Many of the existing signs of the arm tree type guide signs, which are often used in parks and mountain trails, are in an unstable state because the joint between the pillar and the arm tree is structurally poor in durability.

It is an object of the present invention to provide a reinforcing metal fitting for improving the durability of a joint portion between a pillar of an arm-shaped guide sign and an arm.

The present invention is characterized by being an L-shaped guide sign arm reinforcing metal fitting attached to the left and right side surfaces of the column at the joint portion between the pillar and the arm that constitutes the arm-shaped guide sign.

It is a perspective view of the reinforcing metal fitting of this invention. It is a top view which incorporated the reinforcing metal fitting of FIG. FIG. 1 is a rear view of a guide sign incorporating a reinforcing metal fitting.

There are two types of metal fittings, the guide sign arm tree reinforcement metal fitting L type 1 (hereinafter referred to as L type) in FIG. 1 (a) and the guide sign arm tree reinforcement metal fitting reverse L type 2 (hereinafter referred to as reverse L type) in FIG. 1 (b). ).
Generally, the arms 8 and 10 are fixed to the pillar 7 with bolts and nuts 9.
For the purpose of reinforcing it, as shown in FIG. 2, L-shaped 1s are fixed to the arms 8 and 10 through the holes 5 with wood screws 6 on both sides, and the holes 4 are fixed to the pillars 7 with the wood screws 6. By fixing, the blades 3 support the arms 8 and 10 and prevent the arms 8 and 10 from loosening in the rotation direction.
The same applies to the case where the arms 8 and 10 are fixed to the pillar 7 with the wood screws 6 by using the guide sign arm reinforcement metal fitting inverted L type 2.

There are two types of attachment. In FIG. 3A, one L-shaped 1 and one inverted L-shaped 2 are used for the bidirectional arm 8 and the blade 3 is fixed so that the arm is lifted from below.
Further, FIG. 3B, the one-way arm 10 has a left-right direction, and two L-types 1 are used for the left side and two inverted L-types 2 are used for the right side. In the case of a unidirectional arm, the same shape is used to prevent the arm 10 from loosening in the rotation direction by supporting the lower part in the arm tree direction and the upper part on the opposite side with the blade 3.
The blades 3 that support the arms have a strength of 1 ton or more per blade in order to withstand the wind and snow in the high mountainous areas.
