Description

[Detailed description of the invention] [Industrial application field] The present invention is a multifaceted display board that has multiple card storage recesses that have almost the same shape as cards such as telephone cards. The present invention relates to a positioning device for fixing the display surface of cards at a predetermined position in a rotary card display stand that supports the cards so that they can be displayed in an upright state without overlapping.

[Prior art]

Regarding a rotary card display stand that rotatably displays a plurality of card display boards for cards such as telephone cards, the applicant has already proposed this in Utility Application No. 174699/1983, as shown in Fig. As shown in FIG. 2, there is a frame body 7 that is constructed of a frame body 7 on which a plurality of card display boards can be displayed on multiple sides on legs having rotating shafts 8.

That is, the card display stand shown in FIG.
It has a plurality of so-called hexagonal column-shaped display surfaces, is rotatable on its central axis, and has a card display board fitted into each surface, and is suitable for use at storefronts such as card shops. If you place this display stand on it, you can use it as a kind of store decoration, and
The customer can select the desired card by rotating each side of the display stand in turn along the rotation axis or stopping at a desired side.

[Problems with conventional technology]

However, in this type of card display stand proposed by the applicant, the legs 9 are rotated along the rotation axis by bearing means such as ball bearings. When the display stand is rotated, the rotational force is larger than necessary and it becomes unstable, making it difficult to keep the desired side in the direction of the customer, and the side of the card display board does not necessarily face the customer correctly. That's not necessarily the case.

[Means to solve the above problems]

In view of such conventional drawbacks, the present invention provides the rotary card display stand with a ball plunger having a receiving member and a rolling ball at the tip between the leg portion and the rotating frame body. It is an object of the present invention to provide a rotary card display stand in which each side of the rotary card display stand can be fixed at a desired position.

In addition, the applicant of the present application has repeatedly devised different ideas for such positioning means, and has discovered that the number of ball plunger parts and the number of receiving members do not necessarily need to be equal to each surface, and that the number of ball plunger parts and the number of receiving members are not necessarily equal to each other. If a pair of ball plungers are provided symmetrically across the central axis of rotation, the number of ball plunger parts is half the number of required faces (therefore, if it is a hexahedron, it will be three, and if it is an octahedron, it will have half the required number of faces. It has been found that four ball plunger sections are sufficient.

[Effect]

The card display stand positioning device according to the present invention includes:
By providing a pair of receiving members sandwiching the central axis and half the number of ball plunger parts as the number of display surfaces between the legs and the rotated frame, any one of the ball plunger parts can be The required display surface is positioned at a predetermined position by the tip of the ball plunger section entering the groove of one of the pair of receiving members.

[Example of idea]

A positioning device for a card display stand according to the present invention will be explained based on the drawings. FIG. 1 is a schematic diagram of a positioning device for a card display stand according to an embodiment of the present invention, in which 1 is a leg pedestal, 2 is a floor portion of a rotating frame body 3 to which a plurality of card display boards are attached,
The leg pedestal 1 is provided with rolling members 6, 6A to 6C for keeping the heights of the receiving members 5, 5A, 5B and the floor 2 of the rotating frame body 3 uniform and for smooth rotation. , and the floor portion 2
has a coil spring part inside, and as the ball at the tip is pressed against the inclined part 11 of the receiving member and moves, the ball sneaks inside, and when it reaches the groove of the receiving member, the ball Ball plunger portions 4, 4A to 4C having a structure in which a ball pops out are provided. Further, 7 is the central axis of the leg portion, and 8 is the central axis of the rotating frame body 3. In FIG. 1, the leg portion 9 is omitted for convenience.

In this embodiment, since the display stand has six sides, the ball plunger parts 4A, 4B,
4C are arranged at 120 degree intervals from the center, and using three of the rolling members 6, 6A to 6C, 6A, 6B,
It was placed at position 6C.

The operation of the positioning device according to this embodiment will be explained. The center axis 8 of the rotating frame body 3 is aligned with the leg center axis 7, and the rotating frame body 3 is attached to the leg base 1.
Place it on. Then, the rolling members 6, 6A
The rotating surface of ~6C evenly supports the floor 2 of the rotating frame body 3, and the rotating frame body 3 supports the floor 2 of the rotating frame body 3.
faces the leg base 1 and rotates smoothly thereon.

In this case, the ball 15 at the tip of the ball plunger part 4, 4A to 4C arranged on the floor part 2
are the receiving members 5, 5 arranged on the leg base 1.
Since the tip balls 15 of the ball plunger parts 4, 4A to 4C are disposed at a position passing directly above the ball plunger parts 4, 4A to 4C, as they rotate, the tip balls 15 of the ball plunger parts 4, 4A to 4C pass directly above the receiving parts 5, 5A, 5B. 11 pushes the ball 15 inside, and further rotation causes the ball 15 to fit into the groove 1 of the receiving member 5, 5A, 5B.
2, thereby determining the position of the rotating frame body 3.

In order to explain this relationship, FIGS. 2A and 2B show the shapes and structures of the receiving members 5, 5A, 5B and the ball plunger parts 4, 4A to 4C.
In Figures 2A and B, 10 is the attachment part, 11
1 is an inclined part, 12 is a striped groove provided in the center, 13 is a ball plunger main body, 1
5 is a tip ball portion, 16 is a coil spring, 17 is a mounting bolt, and 18 is a mounting nut. As shown in FIG. 2A, the receiving members 5, 5A, 5
B has an inclined part 11 whose height increases toward the center thereof, and has a groove 12 cut in the center thereof, and as shown in FIG. Ball plunger part 4, 4A~4
As the ball part 15 at the tip of C comes into contact with the inclined part 16 as it rotates, as the inclination becomes higher, the ball part 15 touches the ball plunger main body 13.
When it enters the inside and provides resistance to rotation, and reaches the stripe groove 12, this stripe groove 1
2, the rotation is stopped, and the position of the rotating frame body 3 is determined at that position.

In this case, in the case of the hexagonal prism rotating frame body 3 having six required display surfaces, in this embodiment, the receiving members 5, 5A, 5B are placed at two locations at an interval of 180 degrees, and the ball plunger portion 4, By providing three ball plungers 4A to 4C, that is, by arranging half the number of ball plunger sections as required for the display surface with respect to the two receiving members, the display surface can be held at the required position.

In this embodiment, the receiving members 5, 5A,
5B on the leg base 2, and three ball plunger parts 4, 4A to 4C on the floor member 2;
Further, even if two ball plunger parts 4 are provided on the leg base 1, the same effect can be achieved.

Further, as shown in FIG. 4, two of the receiving members 5 are arranged on the bottom plate part 2 facing outward at 180 degree intervals, and three of the ball plunger parts 4, 4A
~4C are attached to the horizontal plate of the leg base 1 at 120 degree intervals facing inward, and these two receiving members 5 and three ball plunger parts 4 allow the rotating frame body 3 to be The display surface may be positioned at a predetermined position.

[Effect of idea]

According to the present invention, by providing the card at the store, customers can freely rotate or stop each of the six sides of the display stand in sequence along the rotation axis and select a desired card from that side.

In addition, since the required display surface stops at the desired position, the customer can stably take out the card, and damage to the card can be prevented. There is no need to worry about increased costs when manufacturing a display stand equipped with a positioning device.
