TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mobile signboard device. More specifically, the present invention relates to a movable signboard that does not fall down due to the action of wind or the like without being fixed to another structure or the like. Further, the present invention relates to a mobile signboard device having a function of increasing or decreasing the number of notification faceplates as desired.
[0002]
[Prior art]
Recently, for example, at a gas station, a mobile type is used as a sign indicating the price of each oil type, or as a sign indicating the entrance or exit of a parking lot of various facilities. This is available with or without casters, but is relatively light so that it can be easily moved in any case. And the structure consists of a base part and a notification face plate mounted on it, and it is common practice to fix this sign to other structures such as pillars only by placing the base part on the ground. Not. Therefore, there is a possibility that the vehicle may fall down when a strong wind blows.
[0003]
As a method for coping with this, conventionally, a weight made of a tank containing water or a sand bag, for example, has been mounted on a base to thereby prevent a fall.
[0004]
However, such a measure is troublesome because the weight must be placed or removed every time the signboard is moved for installation or storage of the signboard. It is also troublesome in terms of storage. Furthermore, if the weight is not properly placed during installation, the weight may not function sufficiently and the signboard may fall. Even if properly placed, it looks very bad.
[0005]
In addition, this type of conventional signboard has a fixed size, and the number of notification faceplates cannot be increased or decreased. For example, it is not possible to add or remove a specific notification faceplate depending on the time zone or season.
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described conventional problems, and has as its object to provide a movable signboard device that does not require a separate weight to be placed on a base and has a sufficient function of preventing falling.
[0007]
It is another object of the present invention to provide a mobile signboard device capable of increasing or decreasing the number of notification faceplates and having a sufficient function of preventing falling down corresponding to the number.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, in a mobile signboard device including a base portion according to the present invention and a notification face plate portion provided upright on the base portion, the base portion has a predetermined planar dimension. A hollow member provided with an inlet and an outlet was provided so that it could be used as a water tank into which water could be injected. As a result, a tank is formed inside the base portion, and a weight such as a conventionally used water tank is not required.
[0009]
In one embodiment, the hollow member is formed in a substantially rectangular frame having a planar shape, and each side of the frame is formed of a hollow rod-shaped member, and the insides of the adjacent rod-shaped members are connected to each other. The parts communicate with each other to form one tank. Various hollow rod-shaped materials are relatively easy to manufacture, and if this material is used, a base having desired dimensions can be manufactured very easily and at low cost. When the base part itself is molded using a molding die, it is necessary to make a die for each different dimension, which increases the cost.
[0010]
In yet another embodiment, the hollow member further comprises a rod-shaped bridge member coupled at both ends to a rod-shaped member forming a pair of mutually facing sides of the frame, wherein the bridge member is hollow. Thus, both ends communicate with the inside of the pair of rod members to form a part of the tank. This increases the strength of the base.
[0011]
In yet another embodiment, the hollow member is formed using an extruded aluminum alloy profile. The bridge member is also formed using an extruded aluminum alloy. Extruded aluminum alloys are easily available and have anti-corrosive properties themselves, so that no separate anti-rust coating is required.
[0012]
In yet another embodiment, the hollow member and the bridge member have a rectangular cross section. Thereby, rigidity can be increased.
[0013]
In still another embodiment, the notification face plate portion is formed by stacking a desired number of individual sign units, between the sign unit placed on the base portion and the base portion, and between adjacent sign units. Between them, there are provided fixing means which can be detached from each other, and the number of sign units can be increased or decreased. This makes it possible to easily add and remove a sign unit as needed, which is extremely convenient. At that time, the amount of water in the tank can be changed according to the number of the sign units, and a sufficient fall prevention function can be achieved, without requiring excessive labor when moving.
[0014]
In yet another embodiment, the water tank is provided with an indicator that indicates the amount of water inside. Thereby, the amount of water in the tank can be known, and the amount of water suitable for the number of installed sign units can be input.
[0015]
