Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a turntable for exhibiting a product having an intermittent rotary motion, and more specifically, a product turntable which can be manufactured at a low cost and which can perform the intermittent rotary motion reliably and smoothly. For turntables.

[0002]

2. Description of the Related Art Conventionally, relatively small and lightweight products such as various products in bottles or boxes in cans, precision machines such as cameras and tape recorders, and various products such as precious metals and stationery are effectively exhibited. A rotary turntable is used to collect the customer's eyes.

[0003]

By the way, the conventional turntables for exhibiting goods merely rotate slowly at a constant speed, so that they attract the customer's attention when compared with a stationary table which does not move. Even if there is an effect, there is a problem that it is relatively easy to get tired because the movement is monotonous.

In order to solve the above-mentioned problems, the present invention improves the monotonous movement of a conventional turntable to surprise the customer with an unexpected movement called an intermittent movement, and concentrates the characteristic portion of a product to be particularly appealed. Therefore, for example, it is possible to perform a trick such that the turntable is intermittently moved at 90 degree intervals so that the front, the left and right side surfaces, and the back surface can be easily seen.

An object of the present invention is to provide a turntable for exhibiting goods, which enables the turntable as described above to be manufactured at a low cost, and at the same time ensures intermittent and smooth rotary motion.

[0006]

Therefore, according to the present invention, a drive source and a speed reducer are built in the pedestal body, and a shaft which is rotated at a constant speed by the decelerator is passed upward through the top plate of the pedestal body. In the stretched product display turntable, a plurality of stopper claws are provided on the top surface of the pedestal main body at appropriate intervals, and the shaft is provided with a brake plate upward from the top plate side of the pedestal main body. The rotating plate and the crank member are inserted and locked in this order, the brake plate is of a size that does not contact the stopper claws, is locked integrally with the shaft, and has a grease layer formed on its upper surface. It is provided at a position where it does not come in contact with the stopper claws and can be slidably contacted with the upper surface of the brake plate. It is engaged with the shaft in a loose fit shape and a slit groove extending in the radial direction is formed in a part thereof. , The crank member The piano wire member is provided at a position above the rotary plate so as to be integrated with the shaft, and the base end portion of the piano wire member is pivotally attached to the crank member, and the tip of the piano wire member is horizontally extended to a position above the slit groove. After being extended, it is bent downward at a substantially right angle to form an intermediate bent portion that is inserted into the slit groove, and the tip of this intermediate bent portion is further bent toward the base end portion to form a downward bent portion. The tip of the bent portion is wound into a coil to form a spring portion, and the tip of the piano wire member at the tip of the spring portion is closer to the center of the rotary plate than the innermost end of the slit groove formed in the rotary plate. Is pivotally mounted on the rotary plate at a position closer to the lower end, the downward bent portion of the piano wire member can freely abut on the stopper claw, and the intermediate bent portion of the piano wire member is in the slit groove of the rotary plate as the shaft rotates. Slide inward The spring is stored in the spring part while the downward bending part slides on the contact surface with the stopper claw, and the downward bending part comes off the contact surface with the stopper claw. In this case, the positional relationship between the bent part of the piano wire member and the stopper claw is maintained so that the downward bent part can freely come into contact with the stopper claw at the next position by the elastic force stored in the spring part. This is a turntable for product display that has an intermittent rotating motion.

[0007]

With the structure of the present invention, when the power source of the drive source is turned on, the shaft starts decelerating at a constant speed, whereby the crank member side end of the piano wire member is rotated together with the crank member, and the piano wire member is rotated. The downward bending portion located near the other end abuts the contact surface of the stopper claw on the top surface of the pedestal, which impedes the rotational movement of the piano wire member and the rotating plate, and therefore the downward bending portion of the piano wire member hits. While sliding the surface in the direction of approaching the crank member, the spring portion is compressed and elastic force is accumulated.

When the downward bent portion is disengaged from the contact surface of the stopper claw, the elastic force accumulated in the spring portion of the piano wire member causes the piano wire member to rotationally move to the next stopper claw position at an increased speed. The rotating plate will move in a similar manner accordingly. Since the present invention is provided with the brake plate, it is possible to control the speed during the rotational movement of the rotary plate. In this way, the table makes intermittent rotary motion.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. As shown in the exploded perspective view of FIG. 1 and the vertical sectional view of FIG. 2, the present invention mounts a drive source 2 such as a motor on a base 1a of a pedestal,
The shaft 4 is rotated through the reduction gear 3 at a constant speed.

The base body 1 is crowned on the base 1a,
A plurality of stopper claws 5 (usually about 2 to 8, but preferably about 4) are provided on the upper surface of the top plate 1b of the base body 1 so as to project. The shape of the stopper claw is, for example, a triangular prism type, and the contact surface 5a is a vertical surface.

The protruding intervals of the stopper claws may be equal intervals or irregular intervals as required. Next, a brake plate 6 is attached to the upper surface of the top plate 1b so as to be integrated with the shaft 4, and a grease layer 7 is formed on the upper surface of the brake plate 6. A rotating plate 8 is attached to the upper surface of the grease layer 7 so as to be loosely fitted to the shaft. A slit groove 9 extending in the radial direction is formed in a part of the rotary plate 8, and an intermediate bent portion 11 of a piano wire member 10 is slidably inserted in the slit groove 9.

The piano wire member 10 includes a spring portion 12
And a downward bent portion 13 are formed, and the downward bent portion 13 comes into contact with the contact surface 5a of the stopper claw 5 in a pressure contact state. A crank member 15 is integrally attached to the shaft 4 on the upper side of the rotary plate 8 via screws 14 and the like, and both ends 10a of the piano wire member 10 are
Numerals 10b are axially attached to predetermined positions of the crank member 15 and the rotary plate 8, respectively.

Further, since the table 17 is integrally attached to the rotary plate 8 via the spacer 16, when the rotary plate makes an intermittent rotary motion, the table 17 makes an intermittent rotary motion, and the table 17 is placed on the upper surface of the table. If the product 18 is placed, this product will perform intermittent rotary motion (see FIG. 10).

Next, the intermittent rotary motion of the present invention will be described. First, when the power source of the drive source 2 is turned on and the shaft 4 is rotated, the brake plate 6 and the crank member 15 integrated with the shaft are separated. Rotate. Rotating plate 8
Since it is loosely fitted to the shaft, it does not rotate integrally with the shaft. Naturally, since one end 10a of the piano wire member 10 is pivotally attached to the rotating plate, its rotation is hindered. ing.

When the crank member 15 rotates, the piano wire member 10 whose one end is rotatably attached to the crank member tries to start rotating around the mounting portion of the crank member, but the downward bending portion of the piano wire member. Since 13 is in contact with the contact surface 5a of the stopper claw 5 protruding from the top plate 1b, it cannot rotate. Therefore, the piano wire member slides in the direction of approaching the crank member 15 while abutting the downward bending portion 13 thereof against the contact surface, and the intermediate bent portion 11 is moved in the slit groove of the rotary plate 8 in the direction of approaching the crank member. Will be moved to (Fig. 4 to Fig. 7)
reference).

When the intermediate bent portion 11 moves in the slit groove in this manner, the spring portion 1 of the piano wire member
2 is compressed while accumulating elastic force, and at that time, the rotary plate 8 and the table 17 are stopped. As this state progresses, the downward bent portion 13 of the piano wire member finally comes off the abutting surface 5a of the stopper claw 5, and there is nothing that blocks the rotation of the piano wire member, so that it is accumulated in the spring portion 12. The elastic force causes the piano wire member and the rotary plate to start rotating at once, and moves to a position where they abut on the next stopper claw.

At this time, the grease layer 7 of the brake plate 6 serves as a rotating plate so that the rotational movement speed does not increase too much and the downward bent portion gets over the stopper claw at the next stopper claw position. The frictional force between the brake plates is increased, and the rotation speed of the rotary plate and the table is adjusted by the action of the oil damper.

When the rotary plate moves to the next stopper claw position as shown in FIGS. 8 and 9, the above-mentioned operation is repeated again, and in this way the rotary plate continues the intermittent rotary motion continuously. .

[0019]

As described above, according to the present invention, since a cam or the like is not used, the processing accuracy and cost of the product are not increased, and the intermittent rotary motion can be performed reliably and smoothly. Has an extremely excellent effect as.
