The linear bases 4 and 5 connected to the hooks 2 and 3 are formed to be inclined in mutually opposite directions.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension ring for suspending a sign board such as a plastic board or a veneer board mainly used in a railway station.

[0002]

2. Description of the Related Art Conventionally, a bulletin board of this type has a hanging ring A in which a fixing bracket is fixed to a wall or a pillar, a rope or a wire is stretched between these fixing brackets, and an elastic wire is formed into an elliptical shape. The bulletin board B is suspended from these suspension rings. In this suspension ring, one terminal portion 10 is flat and formed in a gutter shape, the other terminal portion 11 is formed in a linear shape, and the linear terminal portion 11 is formed on the inner surface of the gutter-shaped terminal portion 10. A pre-stress is applied so as to be pressed (see FIGS. 5 and 6). However, when a suspended bulletin board or the like is blown by a strong wind, the engagement between the gutter-shaped terminal portion 10 and the linear terminal portion 11 is easily disengaged, and the bulletin board B falls off, or the suspension ring itself becomes a rope C or a wire. The train may fall out of the train, causing unexpected accidents on train platforms.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hanger for a bulletin board which does not disengage an engagement portion of the hanger or fall off from a rope or a wire even if a bulletin board is blown by wind. .

[0004]

Means for Solving the Problems In order to achieve the above-mentioned object, in the hanger for notices according to the present invention, the elastic wire 1 is bent into an oval shape, and both ends are bent into hook portions 2 and 3.
When the hooks 2 and 3 are crossed and engaged with the linear bases 4 and 5 connected to the hooks 2 and 3 of the other party, the hooks 2 and 3 are oval so that they come into pressure contact with each other. The linear bases 4 and 5 are formed to be inclined in directions opposite to each other with respect to the plane including the ring. In order to achieve the above object, the surface including the hook portions 2 and 3 may be a plane substantially perpendicular to the plane including the entire suspension ring.

[0005] In order to post the article B using the suspension ring A configured as described above, for example, in the state where the hooks 2 and 3 are not engaged, the suspension ring 8 is inserted into the suspension hole 8 on the upper side of the notice B. A is passed through one of the hooks 2 and 3, and the wire C
, And then hook portions 2 and 3 are engaged. Alternatively, the hooks 2 and 3 are engaged with all the suspension rings A through the suspension holes 8 of the notice B, then the wires C are passed through the suspension rings A, and the wires C are stretched on the wall.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A steel wire or a stainless steel wire is used as the elastic wire 1, and the elastic wire 1 bent into an elliptical shape includes a first curved portion 6 and a second curved portion 7 facing each other. You. When the sign B is suspended as shown in FIG. 4, the first curved portion 6 engages with the hanging hole 8 of the sign B, and the wire C engages with the second curved portion 7. The radius of curvature of the first curved portion 6 is set to be large, and the radius of curvature of the second curved portion 7 is about 乃至 to の of the first curved portion 6. The radius of curvature of the hook portions 2 and 3 at both ends is formed to be approximately the same as or slightly smaller than that of the second curved portion 7, and is formed in a plane perpendicular to the plane including the entire suspension ring. The hooks 2 and 3 are formed such that, when the hooks 2 and 3 are removed, the linear bases 4 and 5 connected to the hooks 2 and 3 are inclined back to back.

[0007]

[Example] JIS standard SUS3 is used as the elastic wire.
04 material having a wire diameter of 2.0 mm, the radius of curvature of the first curved portion 6 is 19 mm at the center line of the wire, the radius of curvature of the second curved portion 7 is also 6 mm, and the major diameter of the suspension ring A is 58 mm.
mm. When the hook portions 2 and 3 are removed, that is, when there is no load, the terminal portions are relatively outwardly spaced apart from each other by about 2 mm.
When the hook portions 2 and 3 were engaged with each other by being deformed so as to have a 0-degree inclination (see FIG. 2), they were formed so that pressure contact stress was applied to each other. Therefore, when the hooks 2 and 3 are engaged with the straight portions 4 and 5 of the other party, the straight portions are twisted once and become intertwined (see FIG. 3). .

[0008]

According to the first and second aspects of the present invention, the hook parts 2 and 3 are mutually connected to the linear base part 4 of the other party.
5, the engaging portion is in a pre-stressed state of a phase pressure contact state, and the hook portions 2, 3 are connected to the hanging ring A via the bulletin board B and the linear base portion 4 of the mating member. , 5 is applied to the hooks 2, 3 so that the hooks 2, 3 are more strongly and deeply engaged with the straight bases 4, 5, so that the suspension ring A is Wire C
There is no departure from.

Claims (2)

[Claims] An elastic wire rod is bent into an elliptical shape, hook portions are bent at both ends, and the hook portions are crossed to form a straight line connected to the hook portions of the other party. When the hooks 2 and 3 are engaged with the roots 4 and 5, respectively, the linear roots 4 and 5 are inclined in directions opposite to each other with respect to the plane including the oval ring so that the hooks 2 and 3 are pressed against each other. Hanging ring for notices formed. 2. The hanging ring according to claim 1, wherein the surface including the hook portions 2 and 3 is a plane substantially perpendicular to a plane including the entire hanging ring.
