JP 2003-331392 A

  In the structure described above, when a track or the like comes into contact, the mediation frame or the connection frame swings against the urging force of the coil spring, and the impact applied to the signal lamp is alleviated. Is interrupted, it returns to its original state by energizing the coil spring, and the signal lamp is returned to the normal position, but the base frame and the intermediate frame are connected with a single connection pin, and also connected to the intermediate frame. Since the frame is connected (pivotally) connected to each other with a single other connection pin, when an external force such as wind pressure is applied to the signal lamp with the connection frame fixed in the normal state, the connection pin is used as an intermediary. One or both of the frame and the connection frame may be easily swung, and the installation state of the signal lamp may not be stable.

  It is an object of the present invention to provide a mounting bracket that eliminates the disadvantages of such a conventional example and has an impact resistance and that can provide an installed state of a pedestrian signal lamp.

  The base frame that is detachably attached to the brace provided on the support column is composed of a central part piece and side part pieces that are relatively provided on both sides of the central part piece, and symmetrical with the side piece of the base frame, respectively. A first connecting pin is inserted through a pair of arc-shaped long holes provided and a pair of through-holes provided in a pair of opposite side pieces of a rectangular frame-shaped intermediary frame engaged between the side pieces. A pair of arc-shaped second oblong holes that are symmetrical to the side pieces of the connecting frame having the intermediate frame attached to the base frame and the side pieces of the pressure receiving piece and the side pieces standing upright on both sides of the pressure receiving piece. A second connection pin is inserted into the second elongated hole and a pair of through holes provided in the other pair of opposite side pieces of the mediation frame, and the connection frame is assembled to the mediation frame. The pressure receiving piece of the connection frame provided with the fixing means for the signal lamp and the central piece of the base frame are pressed with a coil spring contracted between them. That.

  According to the present invention, since the base frame and the intermediate frame are connected by a pair of connection pins, and the intermediate frame and the connection frame are connected by another pair of connection pins, an external force such as wind pressure acts on the signal lamp. However, it is difficult to shake easily, so a stable signal lamp installation state can be obtained. Further, even if a truck hits the signal lamp, the impact force is absorbed and is not easily transmitted to the armrest (post) side. Therefore, a durable pedestrian signal lamp installation state can be obtained.
