Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a reversing decoration device that can be used for displays and the like.

[Problems to be solved by the invention] When a pair of ornaments provided on both sides in the radial direction with respect to the shaft are to be vertically inverted about this shaft, the center of gravity of the entire ornament is located at the center of the shaft. Therefore, there is a problem that reliable inversion cannot be performed.

An object of the present invention is to provide a reversing decoration device capable of reliably reversing a decoration with a simple structure.

[Means for Solving the Problems] A feature of the present invention for achieving the above object is to provide a pair of ornaments which are provided on both sides in the radial direction with respect to the shaft and which are driven to be reversed about the shaft, It is provided with a hollow cylinder body provided on the back surface of the ornament and a movable weight movable inside the hollow cylinder body.

[Operation] Therefore, when the decoration is biased in the reverse direction, the moving weight inside the hollow cylindrical body moves and the center of gravity of the entire body is deviated from the axis. As a result, the upside-down decoration becomes stable at that position.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, the shaft 1 has an arm 2 at one end thereof.
It is rotatably supported by. The arm 2 is rotationally moved around the shaft 2a by a drive mechanism (not shown). A pair of ornaments 3a, 3b having substantially the same size and different surface forms are rotatably attached to both sides of the shaft 1 in the radial direction via bearings 4. One ornament 3a imitates a bear and the other ornament 3b imitates a clown, and both 3a and 3b are integrally formed. At the other end of the shaft 1, a substantially semicircular shield plate 5 that shields the lower decoration of the decorations 3a and 3b is fixed.

On the back surfaces of both the decorations 3a, 3b, there are fixed cylindrical bodies 6a, 6b each having a hollow interior and extending in the radial direction of the shaft 1. Spheres 7a and 7b as moving weights are housed in the hollow insides of the hollow cylindrical bodies 6a and 6b, respectively. Sphere 7a, 7b
Is movable inside the hollows of the cylinders 6a and 6b, and causes the centers of gravity of the decorations 3a and 3b to be displaced. Buffer members 8 having the same shape are fixed to the upper end surface and the lower end surface of the hollow cylindrical bodies 6a and 6b, respectively. The cushioning members 8 ... Have a spherical end surface (the surface facing the inside of the hollow). As a result, the spheres 7a, 7b deviate to one side inside the hollow when they are in contact with the cushioning member 8 as shown in FIG. 4, and their rest positions are stabilized.

Balance levers 9a and 9b, which are U-shaped as shown in FIG. 2, are fixed to the back surfaces of the hollow cylindrical bodies 6a and 6b. The balance levers 9a, 9b extend outward from one side of the hollow cylindrical bodies 6a, 6b and form a gentle curve toward the shaft 1.

FIG. 5 shows a structure for reversing the decorations 3a and 3b and a structure for absorbing the vibration accompanying the reversal.

Reference numeral 10 denotes a circular fixed plate, and the arm 2 rotates and moves on the front surface of the fixed plate. On the fixed plate 10, the balance levers 9a and 9b
On the side of the lever located on the upper side, a ring 11, the side surface of which can contact, is rotatably supported via a mounting plate 11a. Above the ring 11, a damper 12 which is elastically contactable with one side of the hollow cylindrical bodies 6a, 6b is fixed via a mounting plate 12a.

The above is the configuration, and the operation will be described below with reference to FIGS.

The arm 2 rotates clockwise on the front surface of the fixed plate 10 about the shaft 2a (FIG. 1) by a drive mechanism (not shown). At this time, the bear decoration 3a appears on the upper side of the shaft 1 and the lower clown decoration 3b is located on the back surface of the shielding plate 5 and invisible from the front. By the movement of the arm 2, the side of the balance lever 9a fixed to the back surface of the upper ornament 3a comes into contact with the side surface of the ring 11 (Fig. 5). When the arm 2 further moves, the ring 11 rolls on the side of the balance lever 9a as shown in FIG. 6 and urges the ornaments 3a and 3b to rotate counterclockwise about the shaft 1. When the decorations 3a, 3b cross the horizontal position about the axis 1, the spheres 7a, 7b become hollow cylinders 6
Roll inside the hollows of a and 6b in the direction of the arrow. This causes the centers of gravity of the decorations 3a and 3b to be displaced. When the spheres 7a, 7b move to the positions shown in FIG. 7, the center of gravity of the decorations 3a, 3b is displaced by 180 degrees, and the decorations 3a, 3b are instantly inverted up and down about the axis 1. In this way, the clown decoration 3b appears, and the bear decoration 3a is hidden behind the shielding plate 5. When the ornaments 3a and 3b are instantly flipped up and down in this way, the side of the hollow cylindrical body 6b fixed to the back surface of the ornament 3b which has been inverted and moved to the upper side collides with the damper 12 (seventh embodiment).
See figure). Since the damper 12 has elasticity, the collision is absorbed. This absorbs the swinging of the ornaments 3a, 3b about the axis 1 and prevents the ornaments 3a, 3b from making one revolution by any chance.

The moved spheres 7a, 7b come into contact with the cushioning member 8 as shown in FIGS. 4 and 7 and shift to one side, and the rest position is stabilized.

In the present invention, the ornaments 3a and 3b are inverted by the ring 11 which is rotatably supported, but the present invention is not limited to this, and a coil spring may be provided upright. Further, although the spheres 7a and 7b are used as the moving weights, the spheres 7a and 7b are not limited to this, and liquids such as water and oil or sands may be contained in the hollow cylindrical bodies 6a and 6b. In this case, the buffer members 8 ... Are unnecessary.

[Effect] As described above, according to the present invention, the structure for reversing the decoration is simple and the center of gravity can be moved, so that the decoration can be surely reversed. Moreover, it is easy to assemble and can be provided at low cost.
