Description

[Detailed explanation of the idea] Certain signs may be temporarily installed on motorways. The present invention relates to a device for temporarily installing a pole equipped with a sign, which does not normally obstruct vehicular traffic, but when necessary, the pole can be installed slightly extending toward the road side.

Examples will be described with reference to the drawings. A pair of mounting brackets 1 consists of a board 1a and both leg plates 1b,
The board is fixed vertically to the roadside protection wall W. Each of the upper and lower arms 2 and 3 is pivotally connected to both leg plates 1b by a pin 4 at one end. However, both leg plates are provided with stopper pins 5 and 6, and the rotation range of both arms is limited to vertical and horizontal angles. At the tip of the lower arm 3 is a cylinder 7 into which a pole P can be inserted.
is fixed, and its upper surface is formed into an outwardly expanding receiving surface 7a to facilitate insertion. The end of the upper arm 2 is provided with a clamp. The clamping tool is constructed by tightening the free ends of hinged semicircular metal fittings 8 and 9 with bolts 10, and the back surface of the metal fittings 9 is fixed to the end of the upper arm 2.

FIG. 3 shows another embodiment of the clamping tool. A window 9a is provided at the edge of the semicircular metal fitting 9, a pin 11 is fixed thereto, and one end of a link 12 is pivotally connected to the window 9a. Further, the edge of the semicircular metal fitting 8 has a cut groove 8a into which the center part of the link 12 can be inserted, and the free end of the link has a cut groove 8a into which the center part of the link 12 can be inserted.
3 is pivoted. As shown in FIG. 3, when the link 12 is inserted into the groove 8a and the lever located at the solid line position is rotated clockwise, the peak 13 on the back of the lever
A crosses over the contact surface with the semicircular metal fitting 8, reaches the position shown by the chain line, and is self-locked.

The present invention is constructed as described above. The upper and lower arms 2 and 3 are always in a vertical position as shown by the chain lines in Figure 1, and do not obstruct passing vehicles. Arm 3 due to vibration
If there is a risk that the leg plate may fall to a horizontal position, a removable stopper pin (not shown) may be attached to the leg plate 1b. To use it, first fold down the lower arm, insert the pole into the cylinder, and then fix it with the clamp on the upper arm. The length of the pole is about 3m and it is quite heavy,
It can be easily inserted into the cylinder by using the receiving surface, so it can be operated by one person. As described above, the feature of the present invention is that the arm is normally stored in close contact with the wall surface, and the pole can be easily attached when necessary.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) A pair of upper and lower mounting brackets fixed to the road protection wall surface, and a pair of upper and lower arms pivoted at one end of each to the mounting brackets so as to be rotatable within an upright and horizontal angle. It consists of a cylinder that is fixed to the free end of the lower arm and has an outwardly expanding receiving surface into which a pole can be inserted, and a pair of semicircular metal fittings that are hinged together so that the pole can be held.The back of one semicircular metal fitting is attached to the upper arm. A temporary pole device consisting of a clamp fixed to the free end and capable of tightening both semicircular metal fitting ends. (2) A pair of hinged semicircular fittings, one end of which is pivoted to the end of the semicircular fitting on the stationary side, and the center part of which is a link that can be inserted into the cut groove provided at the end of the other semicircular fitting; 2. The pole temporary installation device according to claim 1, wherein the clamping tool is constituted by a lever that is pivotably mounted on the free end of the lever and can rotate to tighten both semicircular fittings.
