Description

Detailed Description of the Invention

[0001]

[Industrial application field] The present invention relates to a simple device for standing and moving a signboard.

[0002]

2. Description of the Related Art Signboards are often installed in places that are easily noticed by people, but apart from permanent signs such as telephone poles, outer wall surfaces, rooftops, and dangerous areas, road construction and sudden danger areas are not covered. For a signboard to be installed for a relatively short period of time such as occurrence, attach two, three, or four legs, draw a reinforcement between the lower legs, put a sandbag on it, and use it as a weight to prevent the signboard from shaking or falling due to wind pressure. ing.
Alternatively, multiple piles are driven into the ground to tie and fix each leg of the signboard.

[0003]

If the erected point of the signboard is flat like a tennis court, the dimensions of each leg will not cause any inconvenience with the initially determined length and angle, and the erection and relocation are easy. It is not easy to choose the best place to set up a signboard because the ground is very different. It takes time and effort to adjust the elevation of the signboard and the horizontal direction. Moreover, there are long and short periods such as road construction. The construction will be completed in a few days and we will have to move to the next. Naturally, the topography of the signboard installation point will also change. Must be on the spot. When a levee is used as a road, a billboard may have to be erected on the slope of the levee toward the road. Therefore, this plan provides a simple signboard erection device to cope with these situations.

[0004]

[Means for Solving the Problems] Two points of a rectangular metal plate are bent upward by ∠90 ° to form a gutter shape, and a non-slip serration is attached to the upper edge of the parallel plates. Insert the signboard leg between the parallel plates and screw it to the square or round pipe to the left or right within approximately ∠160 ° to incline at any position to the semi-fixed position. Axle. A square ring that slides up and down manually is provided around the top of the square pipe, and engages with the serrations on the upper edge of the standing plate and is semi-fixed at an arbitrary angle. Mortar is attached to the outer surface and the bottom surface of the standing plates to form a box-shaped body, which is used as a protective body and weight for this device.

[0005]

[Operation] When a signboard is erected, if this device is used, the degree to which the signboard leg is inserted into the pipe, that is, the expansion and contraction of the leg, can be adjusted depending on whether the signboard erection point is flat, sloped or uneven. Along with tilting the pipe to the left and right and screwing it in, the elevation of the sign standing upright can be easily adjusted and can be set horizontally. Drawing 3 As shown in Drawing 4 and Drawing 4, the ground is displayed and the operation is explained. Further, unlike the conventional installation method, no additional weight is required, and the installation work can be performed easily and quickly, and the removal, transportation and storage are easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present apparatus will be described with reference to the drawings. The device A is shown in the front view of FIG. 1 and the plan view of FIG. Bend two points of a square metal plate upward by 90 ° to form a gutter-shaped base (1), and attach anti-slip saws (2) to both upper edges. A square pipe (4) for inserting and supporting the signboard leg (3) is inserted between the standing plates of the base (1), and a square is formed so as to rotate about ∠160 ° to the left and right about the fulcrum (5) set at the lower part of the pipe. A shaft (6) is horizontally mounted on a fulcrum (5) of the pipe (4) and both upright plates of the base (1).

A square ring (7) that slides up and down manually is provided around the top of the square pipe (4) and engages with a serration (2) attached to the upper edge of the base to incline the square pipe (4). The corner is arbitrarily adjusted and locked, and a fixing screw (8) for the signboard leg (3) fitted in the square pipe (4) is provided on the upper portion of the square pipe. Mortar (9) is attached to the outer surface and the bottom surface of the base (1) to form a protective body and weight of the base (1), and pile holes (10) are vertically penetrated at four corners to fix the base to the ground. Was set up.

This device B is shown in the front view of FIG. 3 and the plan view of FIG. A square pipe (4) supporting a signboard leg (3) is inserted between the standing plates with a semicircle (11) on both upper sides of the base (1), and a circle center (12) below the longitudinal centerline of the semicircle (11) And the lower fulcrum of the square pipe is mounted on the shaft (6), and the upper portion of the square pipe (4) is rotated leftward and rightward about 180 ° within ∠180 °. Base (1)
A semi-circular arc (14) with a shaft centered on the semi-circular arc (14) between the front circumference (13) and the shaft (6) is planted with a male screw (15) at the front center line of the square pipe. To the left and right sides of the square pipe to be semi-fixed arbitrarily. The bottom surface of the base (1) is fixed to the center of the metal substrate (18) having the pile holes (17) at the four corners.

[0009]

The state in which the apparatus of the present invention is used is shown in A of the perspective view 5 and B of the perspective view. Adjust the length and length of the signboard leg (3) of the signboard into the square pipe (4) of the standing device, and fix it by tightening the screws. Since the signboard leg (3) can be expanded and contracted, the device A can be used as shown in FIG. 5 and the device B can be used as shown in FIG. Can be easily maintained. Even if there is a place where you want to put a signboard, there is no reason that you cannot stand because of the terrain. The outline of the condition of the signboard and the ground is briefly shown. Standing signboard,
Easy to carry, remove and store.
