Abstract

PURPOSE:To maintain continuous operation of a driving mechanism used for moving exihibits, etc., for a long time period, without applying any driving power, after the motion is manually started at first without using a motor, a power spring, etc. CONSTITUTION:When a weight 5 is swung manually or in the like way downwardly in the direction indicated by an arrow A, a bar 4 moves by its rotation through a groove formed ina cam 6, but said weight 5 is raised and jumped slidably in relation to said bar 4 by inertia. Then, said weight 5 moves through a shaft 3 to a symmetrical position opposite to the first position thereof. Accordingly, said weight 5, said bar 4 and said shaft 3 rotate again in a direction indicated by an arrow B by tare thereof to return to the first state, and further continue rotating in the direction of the arrow A by inertia and tare thereof, thereby the above motion being repeated. At the result, it can be an attractive ornament, if the appearance of said weight 5 is a pierrot doll, etc.

Description

[Detailed description of the invention] The present invention relates to a movement mechanism used for, for example, display items.

For example, there are quite a number of mechanisms that use power sources such as electric motors and springs to cause objects to move in a variety of ways, and are used for a variety of purposes. In such a mechanism, the existence of a power source such as an electric motor is essential, and since anyone can easily guess the existence of such a power source, it is difficult to use such a power source. When a visible mechanism is used, for example, as a decoration for a store's show window, there is a drawback in that it lacks interest. In addition, in order to compensate for such shortcomings, it is necessary to make a ship with a head-mounted head and make it move with many changes, but this increases power consumption, etc. : Also, the equipment is expensive. and.

Such an expensive device is not suitable for displaying in store windows, and it can be used to decorate store windows. lT
A movement mechanism that can obtain the rich ornaments of h is required.

Therefore, it is an object of the present invention to provide a movement mechanism that can be used to construct a device such as an interesting ornament at a low cost.

According to the motion mechanism of the present invention, the motion mechanism that first starts to be driven by human power continues its motion for a long time without applying any side tube driving force, and continues its motion for a long period of time without requiring any driving force. ``Surface 9 - Whiteness'' It is possible to provide interesting items or JI decorations with a simple structure based on JK.

An embodiment of the present invention will be described below with reference to the drawings. , reveal.

In the embodiment shown in FIG. 1, a cylindrical body 2 is fixed to a base I with its axial direction aligned with the horizontal direction. A shaft 3 is mounted at the axial center position 1η of this cylindrical body 2 by a bearing (not shown).
is pivoted. A set number of rods 4 are fixed to the shaft 3 in a direction perpendicular to the shaft 3, and weights 5 are attached to the rods 4 at sliding positions. Further, a cam 6 is provided on the inner circumferential surface of the cylinder 2 at a position of 61 corresponding to the position of the rod 4 for attachment to the shaft 3. Therefore, the same number of cams 6 as rods 4 are provided.

As shown in FIG. 4, the rod 4 is fixed to the shaft 3 with a bolt 7, and a key 8 is formed in the rod 4 in the longitudinal direction.

5 and 6 show the structure of the weight 5. FIG. That is, a side plate 1 fl is attached to the upper and lower top plates 9,
This side plate lO is connected to the connecting plate 11. They are connected by bolts 12. A bracket 13 is fixed to the top plate 9,
A roller 15 is mounted on a shaft 14 which is supported by this bracket 13.

Further, a hole 16 and a key groove 17 are bored in the top plate 9, and the rod 4 and the key 8 provided on the rod 4 are inserted into the hole 16 and key groove 17. This rod body 4 has a bar 18 between the top plate 9 and the shaft 30.
is inserted loosely.

The operation of the above embodiment will be explained below.

That is, the weight 5 is swung down from the position shown in FIG. 1 in the direction indicated by the arrow by human power or the like.

Then, as shown in FIG.
The weight 5 rotates through a groove provided in the cam 6, but the weight 5 rises as the roller 15 comes into contact with the rising slope of the cam 6, and slides against the rod 4 due to inertia. Jump. The weight 5 is then moved via the shaft 3 to a symmetrical position opposite to the initial position shown in FIG. 1, resulting in the state shown in FIG. 3. Therefore, the weight 5, rod 4, and shaft 3 are again connected to arrow B in FIG.
It rotates by itself 11 in the direction shown by and returns to the state shown in FIG. Then, it continues to rotate in the direction of the arrow in Fig. 1 due to its own M (and inertia), and the movement of "Y" = is repeated.

For example, if the weight 5 is shaped like a clown or other doll by using the movement mechanism described above, it can be used as a decoration.

Or it can be a toy. And, if you apply transformational power, that ridge will continue to move for a long time.

No power source is required and it is very interesting.

As described above, according to the present invention, the motion mechanism that has started to be driven by human power etc. continues the motion for a long time without applying any side tube driving force, and the motion mechanism does not require any driving force for that long period of time. It is possible to provide interesting decorations, toys, etc. with a simple structure based on the "interestingness" of being sustainable. Since such decorations have a simple mechanism, they are suitable for decorations such as shop windows.
Furthermore, since no electricity is required and the device itself is inexpensive, it is possible to obtain decorations at low cost.
