Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rotary platform on which a television, typewriter, sewing machine, etc. can be placed.

[Prior art]

In recent years, with the advancement of living standards and the trend toward cultural life, unit furniture, which has both the role of movable furniture and the role of built-in furniture that can be attached to the wall, has been installed in the drawing rooms and living rooms of each home. It has been prized as furniture with functions that are easy for the human body and people to use. Televisions, typewriters, etc. are placed on the base of this unit furniture to further improve its functionality.

[Problem that the invention attempts to solve]

However, since the conventional space section is nothing more than a stand, the TV placed on the space section can be oriented in an appropriate direction depending on the style and size of the room, the number of guests and family members, the seating position, etc. However, it is often impossible to do so, and the valuable space that would otherwise be available is often not fully utilized. Additionally, there are some turntables, but they are large and mechanically complex, making it difficult to use them as auxiliary tools for household furniture.

Therefore, the object of the present invention is to provide a rotary platform that has a simple structure and can be easily handled by anyone.

[Means for solving problems]

In order to achieve the above object, the present invention includes: a substrate; two space-forming rods arranged in parallel on the substrate; and a fan-shaped fan having an arc portion provided on the substrate and between both the space-forming rods. a guide rail; a support plate that is attached to the sector-shaped main part on the side opposite to the board side of the guide rail and has a hole at the center point of the circle of the arcuate part; and a support plate that is slidably provided in the arcuate part. A rotary plate having a guide element and a tightening bolt screwed into a position where it can be inserted into the hole of the support plate.

[Effect]

With the above configuration, by screwing the tightening bolt of the rotating plate inserted into the hole of the support plate attached to the guide rail on the board, the tightening bolt can be screwed using the guide of the rotating plate as a fulcrum. The part you are holding will be lifted up.

Furthermore, by unthreading the tightening bolt, the rotary plate comes into full contact with and rests on the space-forming rod.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 6.

Fig. 1 is a partially cutaway perspective view of the embodiment turned over, Fig. 2 is a plan view with the rotary plate removed, Fig. 3 is a sectional view taken along line A-A' of the above, and Fig. 4 is B-B' of the same. A line sectional view, FIG. 5 is a reference plan view showing a rotating state, and FIG. 6 is a left side view of this embodiment.

First, reference numeral 1 shown in FIGS. 1 and 2 is a board to be placed in a space of unit furniture, etc. On this board 1 is a space-constituting rod 2 with a rectangular cross section having an appropriate height and length. are attached in parallel with screws 3, forming a space between the front surface of the substrate 1 and the back surface of a rotary plate, which will be described later.

A fan-shaped plate-shaped guide rail 4 is provided between the space-forming rods 2. The guide rail 4
is configured with a width that allows a gap S to be provided between the substrate 1 and a gap S from that position to a rotating plate, which will be described later. The guide rail 4 is formed by fixing one end of left and right end widening parts 4a and 4b to the space-forming rod 2, respectively, and connecting them with an arc part 4c. Further, the other end portions of the left and right end widening portions 4a, 4b are combined to form a main portion 4d.

Reference numeral 5 denotes a horizontal rod that is in contact with the main part 4d of the guide rail 4 and is arranged between the space-constituting rods 2. Similar to the guide rail 4, a space S is provided on the substrate 1, and from that position a rotating plate and a rotary plate, which will be described later, are connected. The width is such that a gap S can be provided between the two.

6 is the main part 4d of the guide rail 4 and the horizontal rod 5
This is a support plate attached to the surface opposite to the substrate 1 of .

The support plate 6 is a semicircular plate having the same thickness as the gap S and having a hole 6a at the center of the circle of the arc portion 4c.

Reference numeral 7 denotes a rotary plate on which a television, typewriter, etc. are placed, and is attached to the surface of the space-forming rod 2. As shown in FIGS. 3 and 4, the rotary plate 7 is fixed with a screw 11 to a U-shaped guide 10 that is slidably attached to the arc portion 4c, and is inserted into the hole 6a. A screw hole 9 is drilled at a position into which a tightening bolt 8 can be inserted, and the tightening bolt 8 is screwed into the hole 9.

According to the above embodiment, as shown in FIGS. 3 and 4, the gap S between the upper surface 21 of the board 1 and the board 1 side 22 of the guide rail 4 and the board 1 side 23 of the horizontal rod 5 is , the board side 24 of the rotary plate 7, the side 25 of the guide rail 4 opposite to the board 1, and the side 2 of the horizontal rod 5 opposite to the board 1.
6 and , so that the guide element 10 can slide without contacting the substrate 1, and the rotary plate 7 can slide between the guide rail 4 and the guide rail 4.
Also, it does not come into contact with the horizontal rod 5.

Next, as shown in FIG. 6, when the tightening bolt 8 is screwed in, the portion of the rotary plate 7 on which the tightening bolt 8 is threaded is lifted. When the amount of screwing is small and the rotary plate 7 is slightly lifted, the tightening bolts 8 support part of the weight of the rotary plate 7 and serve as bearings to facilitate rotation of the rotary plate 7.

Furthermore, when the screwing amount is increased, the base plate 1 of the rotary plate 7
The side 24 and the end 27 of the space-forming rod 2 come into contact with each other, making it difficult to rotate the rotating plate 7.

Furthermore, if the tightening bolt 8 is removed from the base plate 1 by unscrewing, the entire weight of the rotary plate 7 will rest on the space-forming rod 2, and rotation of the rotary plate 7 will become difficult due to friction.

Therefore, by screwing in and unscrewing the tightening bolt 8 threaded onto the rotary plate 7, the rotation of the rotary plate 7 can be made easier or less easy.

[Effect of idea]

As mentioned above, by screwing the tightening bolt threaded onto the rotating plate, inserting it into the hole in the base plate, and pressing it against the base plate, the part where the tightening bolt is threaded onto the rotating plate can be removed. can be lifted using the guide as a fulcrum.

Due to the above-described function of the tightening bolt, for example, if the screwing amount of the tightening bolt is small and does not reach the substrate, the rotary plate is entirely placed on the space-forming rod and becomes difficult to rotate due to friction.

Also, for example, from the above state, increase the screw insertion amount,
By pressing the tightening bolts against the board so that they receive part of the weight of the rotating plate, the tightening bolts act as bearings, and the rotating plate is less dependent on the space-configuring rods, resulting in faster rotation. It becomes easier.

Furthermore, for example, if the screwing amount is increased from the above state, a part of the rotary plate will be pressed against the space-forming rod using the guide as a fulcrum, and as a result, rotation will not be easy.

By using the present invention having the above-mentioned effects, it is possible to obtain a rotary platform in which the rotary plate can be easily fixed and released by simply screwing in and unscrewing the tightening bolt.
