[Structure] A pair of upper and lower lids 1 are overlapped with each other, and an annular ridge 2 which is concentric with the center of the lid is provided on opposing surfaces of the upper and lower lids 1. A curved annular recessed line 3 is formed on the top surface of 2, and an annular body 4 having the same shape as the annular protruding line 2 is provided, and a recess 6 into which a ball 5 is fitted is provided at an appropriate position of the annular body 4, The ball 5 is fitted in the place 6 so that the ball 5 is slightly projected from the front and back surfaces of the annular body 4, and the annular body 4 with the ball 5 is interposed between the curved annular recessed ridges 3 of the upper and lower lids 1. In this case, a fixing portion 7 for fixing the annular body 4 with the balls 5 to the lid body 1 is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotary mounting table on which a TV, an aquarium, a bonsai tree, dishes, etc. are mounted.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, a rotary table on which a TV, an aquarium, etc. are mounted has been proposed. However, the conventional rotary table causes a rotation failure when a heavy load object is placed, so that the mounted television can be smoothly moved. It has the drawback that it cannot be rotated.

The present invention has a technical object to provide a rotary mounting table that solves such a drawback.

[0004]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A pair of upper and lower lids 1 are overlapped with each other, and an annular ridge 2 that is concentric with the center of the lid is provided on opposing surfaces of the upper and lower lids 1. A curved ring-shaped recess 3 is formed on the top surface of 2, and an annular body 4 having the same shape as the annular projection 2 is provided. A recess 6 into which a ball 5 is fitted is provided at an appropriate position of this annular body 4. The ball 5 is fitted in the recess 6 so that the ball 5 is slightly projected from the front and back surfaces of the annular body 4, and the annular body 4 with the ball 5 is formed into the curved annular recess 3 of the upper and lower lids 1 described above. The present invention relates to a rotary mounting table, characterized in that a fixing portion 7 for fixing the annular body 4 with balls 5 to the lid body 1 is provided so as to be interposed therebetween.

[0006]

[Action]

 An annular body 4 is arranged between the two lid bodies 1 in a state where balls 5 of the annular body 4 are in contact with the curved annular recessed ridges 3, and a mounting object 15 is placed on the lid body 1. When 1 is rotated, the ball 5 rolls on the curved annular groove 3 so that one lid 1 rotates well with respect to the other lid 1.

[0007]

【Example】

 The drawings illustrate one embodiment of the present invention, which will be described below.

The upper and lower lids 1 are molded by plastic integral molding, and a peripheral flange 8 is erected on the outer periphery of a disk body whose surface is slip-resistant, and a large diameter is formed inside the peripheral flange 8. The ring-shaped ridge 2 is continuously provided, the small-diameter ring-shaped ridge 2 is further provided inside the large-diameter ring-shaped ridge 2, and the shaft cylinder 9 is erected at the center. A curved ring-shaped recess 3 is formed at the top of the two annular protrusions 2.

Reference numeral 10 is a non-slip protrusion.

The ball holder 11 shown in FIG. 3 is molded by plastic integral molding, and has an annular fitting portion (corresponding to the fixing portion 7) fitted in the shaft tube 9 at the center. An inner annular body 4 having the same diameter as the small-diameter annular ridge 2 is provided on the outer side of the annular fitted portion, and an outer annular body 4 is further provided on the outer side of the inner annular body 4 so as to form the annular covered body. The fitting portion, the inner annular body 4, and the outer annular body 4 are connected by radial ribs 12.

A circular recess 6 is provided at a predetermined position of both annular bodies 4, and a ball 5 is fitted into this recess 6, and the ball 5 slightly protrudes from the front and back surfaces of both annular bodies 4. It is set to be ready.

The both lids 1 are polymerized by fitting the female concave body 13 and the male convex body 14 made of plastic into the respective barrels 9 and press fitting the female concave body 13 and the male convex body 14 together.

Since the present embodiment has the above-described structure, even if a heavy mountable object 15 such as a television is placed on the upper lid 1, the lid 1 is placed against the lower lid 1 by the balls 5. It will rotate smoothly.

Since the balls 5 are held by the ball holders 11, the balls 5 do not come apart and are easy to assemble, and both sides can be used as a mounting surface for convenient mounting. It becomes a table.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it becomes a rotary mounting table which is excellent in practicality and does not impair rotation even when a heavy TV or the like is mounted.
