JPS6038931Y2 - Display stand for rings, etc. - Google Patents

Description

[Detailed Description of the Invention] Conventionally, rings in jewelry stores and the like were simply displayed in a show window.

However, the value of a ring lies in its brilliance, which is based on the reflection of light from the jewels attached to it, and therefore, if it is displayed statically like this, it will not be possible to fully bring out the beauty of the jewels.
In the end, it was far from the best display form to arouse customers' desire to purchase.

This invention allows a display stand for rings, etc. attached to the stand to perform a very unique movement, such as a swing-like rotation while facing forward, and a temporary stop of this movement, thereby making it easier for customers to see. This invention relates to a display stand for rings, etc., which is characterized by being constructed in such a way that it attracts the eye of the user, and also makes the jewelry sparkle based on such a movable display, thereby fully demonstrating its value.

Hereinafter, the configuration of the present invention will be explained in detail with reference to the drawings.

In the figure, 1 is a cylindrical main body, on the top of which is stretched a top plate 2 with a gentle forward slope.
Furthermore, an exhibition seat movement mechanism A as described below is housed inside the stand main body 1.

The exhibition seat movement mechanism A is assembled into a base frame made up of circular chassis chassis plates arranged parallel to each other at a predetermined distance through support columns 3 and attached to the lower surface of the top plate 2. Its structure is as follows.

Reference numeral 4 denotes a drive motor mounted on the first chassis board a located at the lowest position, and the rotation of the motor 4 is controlled via a battery 5 housed within the base body 1.

Further, the rotating shaft of the motor 4 is inserted into the second sheath disk, and a driving pinion 4a is attached thereto.

6 and 7 are reduction gear sets each consisting of a canine gear and a small gear attached to the center thereof; 8 is a reduction spur gear;
It is rotatably and interlockably disposed between the second and third shear sea disks, and the drive pinion 4a of the motor 4 meshes with the large gear of the reduction gear set 6. The rotational force of the motor 4 is transmitted to the spur gear 8 via set gears 6 and 7.
A rotating shaft fixedly provided projects above the third shear sea plate C, and a control gear 9, which will be described below, is fixedly provided.

In FIG. 4, reference numeral 9 denotes a control gear provided on the third shear sea board C, and the gear 9 has a disengagement arcuate portion 9a by continuously cutting a part of its tooth group. is formed.

10 is an intermittent rotating gear that meshes with the control gear 9,
The number of teeth of the gear 10 is configured to be the same as the number of teeth of the control gear 9 (the number of teeth remaining due to the non-engaging arcuate portion 9a shape), and the gear 10 is fixedly installed. The central axis is the fourth
It is projected onto the chassis board d.

10a is a main stopper groove carved at a predetermined location near the periphery of the intermittent rotating gear 10; 11 is a spring-shaped main stopper piece whose base end is fixed to the third shear sea plate C; The vertical engagement piece 11a formed at the tip of the main stopper groove 10a is in pressure contact with the upper surface of the intermittent rotation gear 10 in a state where it can be inserted into the main stopper groove 10a.
(See Figure 7).

That is, the main stopper piece 11 is in pressure contact with the intermittent rotation gear 10 by its own spring force, and the gear 10
is rotated via the control gear 9, and when the non-engaging arcuate portion 9a of the control gear 9 reaches the meshing position of the gear 10 and its rotational driving force is cut off, the main stopper groove 10a and the main stopper The vertical engagement pieces 11a of the pieces 11 match, and the main stopper piece 11 plunges the vertical engagement pieces 11a into the main stopper groove 0a based on its own repulsive force, and the intermittent rotation gear 10 is brought to a stopped state. It is designed to keep the

The main stopper piece 11 has a restoring push-up part 11b formed by slightly bending the central part of the main stopper piece 11 so as to lower it, and a stopper release piece 12 is fixed to the rotation axis of the control gear 9. The stopper release piece 12
The tip of the main stopper piece 11 is located at the push-up portion 11b of the main stopper piece 11, and by pushing up the stopper piece 11, the intermittent rotation gear 10 is prevented from rotating.

Reference numeral 10b indicates a sub-stopper groove carved at a predetermined location on the upper surface of the intermittent rotation gear 10; 13 indicates a spring-shaped sub-stopper piece whose base end is fixed to the third shear sea plate C; The downwardly inclined piece 13a formed in is in pressure contact with the upper surface of the intermittent rotation tooth 10 in a state where it faces a position where it can enter into the sub-stopper groove 10b (see FIG. 8).

That is, the sub-stopper piece 13 is in pressure contact with the intermittent rotation gear 10 by its own spring force, and the gear 10
is rotated via the control gear 9 and the rotational driving force is cut off due to the presence of the non-engaging arcuate portion 9a as described above, when the stopper groove 10b and the downwardly inclined piece of the sub-stopper piece 13 13a coincide with each other, and are configured to exhibit a rotation blocking effect on the intermittent rotation gear 10 at the same time as the main stopper piece 11.

The auxiliary stopper piece 13 works together with the main stopper piece 11 to prevent the intermittent rotation gear 10 from being reversed when a reversal rotational force is applied to the intermittent rotation gear 10 by, for example, touching the exhibition seat B, which will be described later. Therefore, when the rotational force of the control gear 9 is transmitted to the gear 1o, forward rotation is not prevented.

For this purpose, the sub-stopper groove 10b of the sub-stopper piece 13
By using the downwardly inclined piece 13a as the plunger piece, a ratchet-like engagement with the groove 10b is achieved.

14 is an interlocking gear attached to the upper end of the central shaft of the intermittent rotating gear 10 mentioned above, 15 is a pinion that meshes with the interlocking gear 14, and both gears are rotatably attached on the fourth shear sea plate d. Moreover, the rotation shaft of the pinion 15 is made to protrude to the upper surface side of the fifth shear sea plate e.

Reference numeral 16 denotes an operating rod attached to the rotating shaft of the pinion 15, and the upper half of the operating rod 16 is bent obliquely to form a dogleg shape.

Further, the operating rod 16 passes through the sixth chassis plate f located at the highest position and the top plate 2 of the cylindrical table main body 1, respectively, and its upper end protrudes outward so as to be rotatable. .

Reference numeral 17 is a rotation regulating shaft erected on the top plate 2 and close to the rear of the operating rod 16, and is used to prevent rotation relative to the exhibition seat B described below.

Reference numeral B designates an exhibition seat in which a cushion part 18 having a ring setting slit 18a on its upper surface is removably fitted into a frame part 19, and a center part of the lower surface of the frame part 19 is fitted with the operating rod 16. On the other hand, a mounting hole 20 is provided for freely rotatable mounting, and a rectangular guide hole 21 is provided slightly behind the mounting hole 20 for loosely fitting the rotation regulating shaft 17 therein.

Reference numeral 22 denotes a cushioning material attached to the top surface of the top plate 2 so as to be placed on the bottom surface of the exhibition seat B, and is designed to provide cushioning material between the exhibition seat B and the top board 2 without interfering with the oscillating rotational movement of the exhibition seat B. It is intended to fill the space of

The present invention has the above-mentioned configuration, and after setting the required rings, etc. on the cushion part 18 of the exhibition seat B in a state tilted forward, the present invention is stored in a show window or the like. It is intended for use.

In this state, if the motor 4 is energized, the rotational force of the motor 4 will be transmitted to the control gear 9 via the reduction gear assembly 6.7 and the reduction spur gear 8.

At this time, if the control gear 9 is engaged with the intermittent rotation gear 10 as shown in FIG. 4, the rotational force of the motor 4 is transmitted to the pinion 15 via the intermittent rotation gear 10 and the interlocking gear 14 This causes the operating rod 16 to rotate.

Therefore, the exhibition seat B attached to the upper end of the operating rod 16 slowly makes a swing-like rotational movement.

On the other hand, since the exhibition seat B has its guide hole 21 slidably fitted to the rotation regulating shaft 17, the operating rod 16
Rotation around the rod 16 due to the rotation of the ring is well prevented, and the exhibition seat B is rotated in a swinging manner while facing in the same direction, i.e., the jewelry of the set ring. This results in a swing-like rotational movement with the part always facing forward.

Next, in the state shown in FIG. 4, as the control gear 9 rotates, the non-locking arc portion 9a reaches the meshing position of the intermittent rotation gear 10, and the rotational driving force to the gear 10 is cut off. In this case, the above-mentioned oscillating rotational movement of the exhibition seat B stops, and the rotation preventing action by the main stopper piece 11 and the sub-stopper piece 13 as described above acts on the gear 10. .

If the control gear 9 further rotates and engages with the intermittent rotation gear 10 again to rotate it, the exhibition seat B will be started again based on the interlocking operation as described above, and on the other hand, as described above, the main stopper The piece 11 is automatically released via the release piece 12, and the sub-stopper piece 13 is automatically released by the ratchet-like action of its downwardly inclined piece 13a.

The above-mentioned cycle of intermittent oscillation rotation of the exhibition seat B is based on the fact that the number of teeth of the control gear 9 and the number of teeth of the intermittent rotation gear 10 are the same. The robot stops when it rotates once, and after stopping for a predetermined period of time, it rotates once again, and so on.

Further, the exhibition effect can be maximized by setting the stop position so that the stop is forced when the exhibition seat B is at the frontmost position.

According to the present invention having the above-mentioned configuration, the exhibition seat B attached to the stand performs a swing-like rotational movement while always facing forward, and the movement is made at a rate of 100° each time it rotates. Since it is possible to create a very unique movement in which the ring remains in a stopped state for the required time, it not only attracts the attention of customers based on this unique movement, but also lights the set ring appropriately. As a result, the jewel of the ring exhibits a good light reflecting effect due to the above-mentioned movement, further emphasizing its beauty and encouraging customers to purchase it.

Furthermore, in the present invention, as mentioned above, exhibition seat B is held in a stopped state for a predetermined period of time, so that the uniqueness of the exhibition form is further improved, and when it is stopped, the construction of the ring can be carefully confirmed. Not only is this permitted, but the present invention also allows such stop control to be performed by
The intermittent rotation of the exhibition seat B is extremely stable and stable since the control gear 9 with the gear 9 and the intermittent rotation gear 10 with the same number of teeth as the gear 9 are engaged and disengaged. In addition to smooth movement, the stop position is always constant, and the possibility of deviation of the stop position is avoided.

Since the present invention has excellent functions and effects as a whole as described above, it can be used not only as a fixture for displaying rings in jewelry stores, but also for other watches.

It is also perfect for displaying pendants, necklaces, etc.
