Description

[Detailed description of the invention] This invention operates the movable display board of the auxiliary display by the electric motor that operates the movable display board of the main display, and simultaneously converts the display contents of the main display and the auxiliary display. This relates to a variable display that can be used.

2. Description of the Related Art Conventionally, variable display devices have been proposed that include a main display and an auxiliary display and change the display content of the auxiliary display in response to the conversion of the display content of the main display. However, the conventional variable display
Since the movable display board of the main display and the movable display board of the auxiliary display are operated using separate electric motors, a special detection device is required to match the display contents of both, and the entire device is Not only is this complicated, but there is also a disadvantage that if a movable part malfunctions, the content displayed on the main display and the content displayed on the auxiliary display will be inconsistent, especially when the variable display is used as a traffic sign. There was also the risk of causing unexpected confusion due to discrepancies in displayed content.

This invention solves the above problems,
By configuring the movable display board of the main display and the movable display board of the auxiliary display so that they can be operated simultaneously by a single electric motor placed on the main display side, a detection device that is likely to cause malfunction is eliminated. In addition, even if a movable part malfunctions, the content displayed on the main display and the content displayed on the auxiliary display will match, preventing display inconveniences and confusion, and the main display and auxiliary display The aim is to make the main body thinner and to increase the compatibility of auxiliary displays.

Embodiments of the present invention will be described below with reference to the drawings.

In the drawings, 1 is a main body display of a variable display. In this embodiment, a so-called rotary variable display is used as the main body display 1, and a fixed display board 3 and a movable display board 4 are housed in a cylindrical box body 2, and the movable display board 4 is connected to an electric motor. (not shown)
By rotating the display board 3 using the , it is possible to move it to the front of the fixed display board 3 and change the displayed content. An auxiliary display 5 is attached to the lower rear surface of the main display 1. The auxiliary display 5 houses a fixed display board 7 and a movable display board 8 in its main body 6, and the movable display board 8 can freely move up and down on the front surface of the fixed display board 7, and It is possible to change the display contents of the display window 9 formed in the display window 9. This auxiliary display 5 has its main body 6
In order to make the display thinner, four sprockets 10a, 10b, 10 are installed above the display window 9 in the frame 6.
The four sprockets 10a, 10b, 10c, 10d are arranged at a predetermined distance from each other in the vertical and horizontal directions, and two sprockets 10a located on diagonal lines are arranged in a plane. and 10c, 10b, and 10d as a set, with a slight height difference between one set of sprockets 10a and 10c and another set of sprockets 10b and 10d in the front-rear direction, and these four sprockets 10a. ,10b,10c,1
Chain 11 is stretched across 0d in a cross-legged manner. In this embodiment, four sprockets 10a, 10b, 10c, and 10d are rotated by rotating one sprocket 10a located at the top of the frame body.
The chain spanned between can be freely moved in a predetermined direction, and the chain 11, which moves vertically at the left and right ends, can be moved upwardly or downwardly at the same speed on the left and right sides, and simultaneously on the left and right sides. The chain 1 is located on the outside of the left and right ends of this chain 11.
A guide rod 12 is arranged along the moving direction of the chain 1, and a mounting plate 13 fixed to the movable display plate 8 is fitted onto the guide rod 12.
Connect the left and right ends of 1. Therefore, chain 11
When the left and right ends of the chain 1 move up and down, the mounting plate 13
The movable display board 8, which is suspended from the chain 11 via the mounting plate 13, can be freely moved up and down on the front surface of the fixed display board 7. The movement range of the chain 11 is regulated by an operating range detection device (not shown) such as a micro switch provided on the main body display 1 side, and the movement direction of the chain can be reversed if desired. ing. The rotating shaft 14 of one sprocket 10a of the auxiliary display 5 constructed as described above is connected to the rotating shaft 15 on the main display 1 side. In this embodiment, the rotating shaft 15 on the main body display 1 side is connected to the rotating shaft 16 for rotating the movable display plate 4 of the main body display 1, and the sprockets 17 and 18 fixed thereto, and between these sprockets 17 and 18. Suspended chain 1
9, and at the same time as the movable display plate 4 of the main body display 1 operates, its rotational force is transferred to the rotating shaft 15.
It has become possible to transmit information to Therefore, the operations of the movable display plate 4 of the main display 1 and the movable display plate 8 of the auxiliary display 5 can be matched without using a special detection device for comparing the operations of the two. Also, from the main display 1 side to the auxiliary display 5
By interposing an appropriate connection device such as a shaft joint on the rotating shafts 14 and 15 that transmit the driving force to the side, it is possible to attach and detach the auxiliary display 5 to the main display 1, thereby making maintenance of the auxiliary display 5 easier. In addition to facilitating inspection and replacement, it is also possible to use only the main body display 1 alone if desired.

Since the variable display according to the present invention is constructed as described above, it is possible to constantly display both the movable display board of the main display and the movable display board of the auxiliary display without using a special detection device to check the operation of the movable display board. It is possible to match the contents and prevent inconvenience and confusion due to mismatched display contents even if a movable part malfunctions, and it is also possible to reduce the thickness of the main body display and the auxiliary display. . In addition, by making the auxiliary display removable, it increases the compatibility of the auxiliary display, allows the main display to be used alone, expands the range of use as a variable display, and furthermore, maintains and inspects the auxiliary display. It also has the effect of facilitating exchange.
