Description of the Related Art Conventionally, as a frame structure of a movable sign board of this type, for example, Japanese Utility Model Registration No. 3013886 discloses a fixed rectangular shape formed by upper and lower horizontal frames and left and right vertical frames for mounting the sign board. On the back side of the frame, there is described a fixture for a construction signboard having a leg for supporting the fixed frame at a predetermined angle. This leg is composed of two left and right vertical rails and one lower horizontal rail, and the upper ends of the two left and right vertical rails are connected to the middle of the back surface of the fixed frame by support brackets. The support bracket is formed in a U-shaped cross section, and the upper end of the vertical rail is fixed to the support bracket with a fixing pin while the upper end of the vertical rail is held at the base thereof. Is fixed to the fixed frame by a mounting pin so as to be rotatable with the pin held between the fixed frame.When stored, it can be adjacent to the vertical frame of the fixed frame almost in parallel, and when used, the upper part of the base is fixed. By rotating the leg until it comes into contact with the vertical frame of the frame, the fixed frame can be erected at a predetermined inclination angle with the lower horizontal frame positioned on the road surface side.

[0003]

However, the frame structure of the movable signboard as described above is unstable when stored adjacent to the vertical frame of the fixed frame in parallel because the legs are not locked at all. In addition, there is a problem that the legs swing unnecessarily, and when the fixed frame is turned upright at a predetermined inclination angle by rotating the legs, the upper portion of the base is the vertical frame of the fixed frame. And the rotation to the fixed frame side is not locked at all, so it is unstable, the leg rotates due to wind pressure, etc., and the angle between the leg and the fixed frame There is a problem that the fixed frame falls down due to the narrowing. Furthermore, in use, it is limited to use with the lower horizontal frame positioned on the road surface side.For example, if a fixed sign is attached to a fixed frame with a signboard that indicates an arrow in one direction, turn it upside down Can not do
In the case where the sign in one direction cannot be made and the sign in the opposite direction is made, it is necessary to replace the sign with the arrow in the opposite direction or to attach this sign to another fixed frame. There was also.

Accordingly, the present invention has been made to solve the above-mentioned problems, and has a movable sign plate frame which can be stably engaged with a fixed frame during storage and use, and which can be used upside down. It does not provide a structure.

The support bracket 4 has a triangular vertical direction about the rotation shaft 6. Cutouts 41, 42 and diagonally cutouts 43, 44 have side plates 45 formed vertically. The cutouts 43 and 44 in the oblique direction may be formed at different angles in the vertical direction, or may be formed at the same angle in the vertical direction.

The locking lever 5 is rotated in conjunction with the leg 3, and the longitudinal notches 41, 42 and the oblique notch are provided at the tips of the left and right vertical rods 51 by the elastic force of the spring 7. A stopper portion 53 is formed on each of 43 and 44 so as to be detachable. That is, the leg 3 and the locking lever 5
The guide plate 8 is provided between the support rod 31 of the leg 3 and the vertical rod 51 of the locking lever 5, and one end of the guide plate 8 supports the leg 3. The rod 31 is fixed to the rod 31 by welding or the like, and a guide hole 81 is provided at the other end. The distal end of the vertical rod 51 of the locking lever 5 is inserted into the guide hole 81 and is not fixed. In the direction, the leg 3 and the locking lever 5 are rotated in conjunction with each other by the guide plate 8, and the locking lever 5 is vertically movable by a guide hole 81.

Further, at the tip of the locking lever 5,
At its tip, vertical cutouts 41 and 42 and oblique cutouts 43 and 44 formed on the side plate 45 of the support fitting 4.
A stopper portion 53 having a triangular tip is formed corresponding to the above. A spring 7 for urging the stopper portion 53 in the direction of the side plate 45 of the support fitting 4 is fitted between the stopper portion 53 and the guide plate 8.

The locking lever 5 linked to the body 3 is rotatable by 180 degrees with respect to the support fitting 4. In use, the locking lever 5 opens the leg 3 in the direction of the lower horizontal frame 22 and locks it. By locking the stopper 53 of the lever 5 to the notch 44 in the lower oblique direction, the fixed frame 2 can be erected at a predetermined inclination angle with the lower horizontal frame 22 positioned on the road surface side. . Further, the upper horizontal frame 21 is positioned on the road surface side by opening the legs 3 in an inclined shape toward the upper horizontal frame 21 and locking the stopper portion 53 to the notch 43 in the upper oblique direction. Thus, the fixed frame 2 can be erected at a predetermined inclination angle, and the fixed frame 2 can be erected upside down.

If the notches 43, 44 in the oblique direction formed in the support fitting 4 are formed at different angles in the vertical direction,
When the lower horizontal frame 22 is positioned on the road surface side and when the upper horizontal frame 21 is positioned on the road surface side, the inclination angle of the fixed frame 2 that is erected can be made different. If the cutouts 43 and 44 in the directions are formed at the same angle in the vertical direction, the lower horizontal frame 22 is positioned upright on the road surface side and the upper horizontal frame 21 is positioned upright on the road surface side. The inclination angle of the fixed frame 2 can be made the same.

It is preferable that the inclination angle of the fixed frame 2 at the time of standing is set so as to be about 70 degrees with respect to the road surface. When the inclination angle of the fixed frame 2 is increased, the visibility is improved. If the angle of inclination is reduced, on the other hand, it becomes difficult to fall down, but the visibility decreases.

The stoppers formed at the tips of the left and right vertical rods of the locking lever that is rotated by the lever are removably engaged with the vertical notch and the oblique notch by the elastic force of a spring. When the leg is stored parallel to the vertical frame of the fixed frame, the stopper of the locking lever is locked in the vertical notch, so the leg is stable and unnecessary. When the leg does not swing, and the fixed frame is turned upright at a predetermined angle by rotating the leg, the stopper of the locking lever should be inserted into the notch in the oblique direction. Since the legs are locked, the legs are also stable, and the legs do not rotate due to wind pressure or the like. Therefore, the angle between the legs and the fixed frame is narrowed and the fixed frame does not fall.

Further, in use, the lower horizontal frame is formed by opening the legs in an inclined manner toward the lower horizontal frame and locking the stopper portion of the locking lever into the lower oblique cutout. The fixed frame can be erected at a predetermined inclination angle while being positioned on the road surface side, and the legs are opened in an inclined manner toward the upper horizontal frame and the stopper is cut out in the upper oblique direction. The fixed frame can be erected at a predetermined inclination angle while the upper horizontal frame is positioned on the road surface side, and the fixed frame can be used upside down. Therefore, for example, even if a sign plate that indicates an arrow in one of the left and right directions is attached to the fixed frame, when performing the sign in the opposite direction, the upper and lower sides are turned upside down to reverse the above. Can show direction arrows Can also by forming such different angles of the notch of the upper and lower diagonal directions up and down, it is possible to change the inclination angle of the fixed frame by vertically inverting.
