Description

[Detailed Description of the Invention] <Industrial Application Field> In this invention, multiple panels are connected to form a link mechanism through arms so that they can move up and down. Regarding the display that rises after

<Prior Art> Conventionally, this type of display has had a plurality of panels connected in parallel via arms so as to form a so-called magic hand type link mechanism at the side surfaces thereof. An arm attached to the top of the front-most panel is attached at its center to the center of the rear panel, and the rear end of the arm is attached to the bottom of the further back panel.
In this way, the panels connected one after another form a link mechanism together with the arm, and are moved up and down by raising and lowering one end of the arm. When it was raised, each panel could be viewed at a glance, and when it was lowered, the panels overlapped, so that only the panel in front was visible.

<Problems that the invention seeks to solve> However, such displays lacked interest because each panel simply moved up and down in a monotonous manner.

<Means for solving the problems> In order to eliminate the above-mentioned drawbacks, the present invention has the following features:
The configuration was as follows. In other words, the first panel, the second panel, and the third panel are arranged in parallel from the rear to the front, the arm is located on the side wall between the adjacent panels and links each panel so that each panel can be folded, and the arm of the second panel It consists of a control claw pivotally supported on the upper half of the side wall, a tension spring connected to the lower end of the first panel and the upper end of the second panel, and a drive mechanism that moves each panel and arm up and down. A first upper arm that connects the middle of the first panel and the upper part of the second panel, and a first upper arm that connects the lower part of the first panel and the middle of the second panel parallel to the first upper arm, and a A first lower arm having one protrusion connects the middle of the second panel and the upper part of the third panel, and a second lower arm having a second protrusion on the rear extension line thereof.
an upper arm, and a second lower arm that connects the lower part of the second panel and the middle of the third panel in parallel with the second upper arm, and the control claw extends substantially forward and downward;
It has a first claw that is temporarily locked by the first protrusion of the first lower arm, and a second claw that extends substantially downward and is kicked up by the second protrusion of the second upper arm,
Moreover, the first claw is biased downward.

The present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a perspective view showing a state in which each panel is rising, and FIG. 2 is a perspective view showing a state in which each panel has finished rising.

1 is the first panel, 2 is the second panel, 3 is the third panel, 4 is the tension spring, 5 is the vertical mechanism, 11 is the first
Upper arm, 12 is a first lower arm, 13 is a second upper arm, 14 is a second lower arm, 15 is a first projection, 1
6 is a second protrusion, 30 is a control claw, 31 is a first claw, 3
2 is the second claw.

Each panel is made of metals such as iron, brass, and aluminum, as well as plastic. Alternatively, only the frame of the panel may be made of the above material, and the pattern portion of the panel may be made of another material such as paper.
A base is attached to the panel closest to you. The base is equipped with a vertical mechanism to move each panel and arm.

The arm is made of metal such as iron or brass, or plastic. A first protrusion 15 is provided on the forward extension line of the first lower arm 12. This first protrusion 15 is held by the first claw 31 of the control claw 30, and is used to keep the first lower arm 12 and the second upper arm 13 in a straight line when the first claw 31 is disengaged. belongs to. Further, a second protrusion 16 is provided on the rear extension line of the second upper arm 13. This second
The protrusion 16 is for pushing the second claw 32 of the control claw 30 to release the first claw 31 and for keeping the first lower arm 12 and the second upper arm 13 in a straight line.

The panel and arm are fixed using pins so that they can rotate. Alternatively, a portion of the panel or arm may protrude to also serve as a pin.

Attach an arm to the side wall of each panel. The arm attached to the bottom of the side wall of the panel is attached to the center of the side wall of the front panel. The arm attached to the center of the side wall of the panel is attached to the upper part of the side wall of the panel further forward. Repeat this process until the arm is attached to the panel.
The panel and arm form a so-called magic hand type link mechanism. Further, the first panel 1 is arranged to be lowered relative to the second panel 2.

A control pawl 30 is provided on the side wall of the second panel 2 above the support points of the first lower arm 12 and the second upper arm 13. The control claw 30 includes a first claw 31 that holds the second first protrusion 15 of the first lower arm 1.
and a second claw 32 that is pushed by the second protrusion 16 of the second upper arm 13.

The control claw 30 is made of metal such as iron or brass. The control pawl 30 is rotatably fixed to the panel with a pin, and a spring is attached to its shaft, so that a force always acts in the direction in which the first pawl 31 holds the first protrusion 15. A positioning pin 17 is provided immediately above the control claw 30 to prevent it from rotating loosely.

A tension spring 4 is attached between the lower end of the second panel 2 and the upper end of the first panel 1. This tension spring 4 is for attracting the first panel 1 and the second panel 2 and lifting the first panel 1 when the control claw 30 is disengaged from the first protrusion 15.

The vertical mechanism 5 for raising and lowering each panel and arm is appropriately constructed using a motor, spur gear, crank, or the like. The vertical mechanism 5 may be attached directly to the arm, or may be attached to a panel or a pin on the arm, in order to raise and lower the arm.

Note that the display described above is only one embodiment of the present invention, and can be implemented in various other forms.

Other possible configurations include one in which the number of panels is changed, one in which multiple panels are made to protrude instead of only the first panel, and one without a base.

<Function> When the arm rises due to the drive of the vertical mechanism 5,
The panel rises accordingly. The rearmost first panel 1 has a first claw 31 attached to the first lower arm 12.
Since the protrusion 15 is held, it does not rise against the second panel 2 (see FIG. 1).

When the arm further rises, the second upper arm 13
The second protrusion 16 pushes the second claw 32 and the first claw 31
is removed from the first protrusion 15.

When the first claw 31 is removed from the first protrusion 15, the first lower arm 12 and the second upper arm 13 are aligned in a straight line by the tension spring 4, and the first panel 1 is raised (see FIG. 2).

Next, as the arm lowers, each panel also lowers. Since the first lower arm 12 and the second upper arm 13 descend in a straight line, the first protrusion 15
The first claw 31 is engaged with the first claw 31 .

When the arm rises again, the first panel 1 does not rise because the first claw 31 holds the first protrusion 15. In this way, the panel is repeatedly raised and lowered.

<Example> An embodiment of the present invention is shown below.

The panel, arm, and base were made from iron plates. A pattern drawn on styrene foam was glued onto the panel.

The base has a vertical mechanism. The vertical mechanism consists of a motor, spur gear, crank, and dry battery.

Additionally, a tension spring was installed between the frontmost panel and the arm to reduce the load on the vertical mechanism.

<Effects of the invention> This invention is a display in which multiple panels are connected by an arm on the side and the panels move up and down, so that when each panel rises, the rearmost panel rises so that it pops out after a delay. Therefore, a display with changes in movement can be obtained.
