Description

[Detailed description of the invention] "Industrial application field" The invention is based on a pair of semicircular shapes that are attached to the back side of road signs and other signboards to strengthen them, and that hold support posts for attaching the signboards. The present invention relates to a mounting member for attaching both legs of a fastening fitting.

``Prior art'' The most convenient mounting member of this type is the
No. 61-5380.

As shown in FIGS. 4 to 6, this mounting member has a hook-shaped tip facing opposite to the joining surface of the board 2, which is joined to the back surface of the sign board 1 by welding or the like. A pair of hook-shaped plates 3, 3 are formed in a protruding state, and opposite sides 31 of the tips of the hook-shaped plates 3, 3,
31, two paired notch grooves 32, 32, 3
3, 33, and the leg portions 51, 51 of a pair of semicircular fastening fittings 5, 5, which hold and fix the sign board mounting support 4 which is set up on the road surface, are connected to the respective pair of notches. The legs 51, 51 of the fastening fittings 5, 5 are inserted into the grooves 32, 33 and locked into each pair of notch grooves 32, 33 as shown in FIG.
A rib a is formed in the longitudinal direction between the hook-shaped plates 3, 3 of the base plate 2 so that the legs 51, 51 are in contact with each other when the base plate 2 is inserted.

Then, in the state shown in FIG. 5, the sign board 1 is attached to the support post 4 by guiding the post 4 between the fastening fittings 5, 5 and tightening the fastening parts 52, 52 with bolts and nuts (not shown). ing.

Since the mounting member is formed with the rib a, the fastening metal fittings 5 remain intact even if the fittings 5 are removed from the legs when the leg portions 51 of the fastening metal fittings 5, 5 are inserted into the pair of notch grooves 32, 33. are notched grooves 32, 33
In addition to being effective in preventing the metal fittings 5, 5 from coming off, the board 2 is reinforced with the ribs a.
When tightened to the column with bolts and nuts, leg 5
1 strongly contacts the substrate 2 and becomes tensed, the sign board on the front side is not easily deformed.

"Problems to be Solved by the Invention" The conventional mounting member described above has the above-mentioned effects, but the leg portion 51 is connected to the pair of notch grooves 32 and 3.
3, when the metal fittings 5 are removed, the fastening metal fittings 5, 5 swing to both sides as shown in Fig. 6, making it difficult to fit them together, which has the disadvantage of reducing the efficiency of the work of attaching the sign board to the post. .

An object of the present invention is to provide a mounting member that eliminates these drawbacks.

"Means for Solving the Problems" The mounting member according to the present invention is formed by floating the rib a in the conventional member from the substrate 2 on the opposing inner surfaces of the hook-shaped plates 3 and 3 in FIG. It is characterized by

``Function'' When the legs 51 of the fastening metal fitting 5 are inserted into the pair of notch grooves, both ends of the leg parts 51 touch the ribs, so even if the fastening metal fittings are released, the fastening metal fittings do not shake and fit well.

"Embodiment" A preferred embodiment of the mounting member according to the present invention will be described with reference to FIGS. 1 to 3.

Reference numeral 2 denotes a board that is joined to the back surface of the sign board 1 by welding or the like, and on the opposite side of the joining surface, a pair of hook-shaped boards 3, 3 whose tips are opposed to each other and bent into a hook shape are integrally formed to protrude. , opposite sides 3 of the tips of the hook-shaped plates 3, 3
1, 31 have two notch grooves 32, which form a pair.
33, 32, 33 are formed.

Each pair of notch grooves 32, 33 is provided with a pair of approximately semicircular fastening fittings 5, as in FIG.
The legs 51 of each are inserted and locked, and the second
By guiding the strut 4 between the fastening fittings 5, 5 as shown in the figure, and tightening the fastening parts 52, 52 formed at the opposite ends of the legs 51 of each fitting 5 with bolts and nuts (not shown), A sign board 1 is attached to a support post 4.

On the opposing inner surfaces of the hook-shaped plates 3, 3, when the legs 51 of the fastening fittings 5, 5 are inserted into the respective notch grooves 32, 33 and the fastening fittings 5, 5 are opened left and right, Ribs 34, 34 floating above the substrate 2 are formed in a state where both ends of the leg portions 51 are in contact with each other.

Since the ribs 34, 34 are formed on the opposing inner surfaces of the hook-shaped plates 3, 3, even if the legs 51 are inserted into the notch grooves 32, 33 and the hand is removed from the fastening fitting 5, the fitting 5 does not swing to the left or right in Fig. 3, and the sign plate 1 to the pillar 4
This makes installation easier and more efficient.

Furthermore, when the fastening fittings 5, 5 are fastened to the support column 4 as described above, the legs 51 of the fittings 5 are attached to the ribs 4.
Even if the ribs 34, 34 come into strong contact with the substrate 2 and become tense, the ribs 34, 34 float away from the substrate 2 to the opposite side of the bonding surface, so the sign board welded to the front side of the substrate 2 cannot be It will not transform. For example, when the substrate 2 is thin, the legs 51 of the metal fittings 5
If the part of the thin sign board rises even slightly toward the surface due to strong tension, the surface of the sign board will partially become slightly curved, and that part may become invisible due to the reflection of light. Although there are many cases,
In this embodiment, the ribs 34 float above the surface of the substrate 2, so there is no such concern.

In the above embodiment, the substrate 2 and the hook-shaped plates 3, 3
And each rib 34 is integrally molded from an aluminum alloy.

"Effect of the invention" The mounting member according to the invention has a structure in which the legs of the fastening fitting are inserted into the notch grooves on both sides of the tip of the hook-shaped plates on the opposing inner surfaces of a pair of hook-shaped plates. Since the ribs are formed in contact with each other, when the leg is inserted into the notched groove, it will fit without shaking even if you remove your hand from the fastening fitting, making it easier and more efficient to attach the sign board to the post. can be implemented.

Moreover, even if the legs of the fastening metal fittings are tightened to the pillar and come into strong contact with the ribs, the sign plate will not be deformed.
