Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) This invention is mainly used for circular fixed sofas in cafeterias, social clubs, etc., which can be easily accessed when sitting at or leaving a table. The present invention relates to a slide table in which the table is manually rotated and slid in order to widen the distance between the table and the sofa.

(Prior Art) Generally, the distance between a dining table and a chair is approximately constant, so when a person takes a seat or leaves the table, the chair is usually moved. However, if these tables and chairs are fixed, especially if they are large sofa-type chairs, it is impossible to move the sofa, so you can sit down or leave by sliding your body into the gap between the table and sofa. was going there.

(Problem that the invention aims to solve) Therefore, this invention was developed to make it easier to take a seat and leave the table by rotating and sliding the table to widen the distance between the table and the sofa. belongs to. First, fix the bracket at right angles to the leg mounting plate at the center of the table, fit the key shaft of the fan-shaped rotating frame that can freely rotate left and right around the bearing into the bearing provided at one end of the bracket, and then fit the key shaft of the fan-shaped rotating frame that can freely rotate from side to side around this bearing into the bearing provided at one end of the bracket. A wheel support plate is fixed, and several wheels are attached to the tip of this plate to roll in an arcuate groove rail formed on the periphery of the fan-shaped rotating frame, and automatic return devices are installed on each side of the bracket. Attach the end rollers of these arms to the grooves of the groove plate protruding inside the arcuate groove rail. Align the center of the fan-shaped rotating frame with the center line of the bracket and fix it to the back of the table top. This is a rotating slide table made of

As a result, when the table top is rotated manually, the rotating frame rotates about 30 degrees to the left or right around the latch axis, increasing the distance between the table and the sofa. When the automatic return device operates, the arm returns and the table returns to its original center.

(Means for Solving the Problems) An embodiment of the present invention will be described below with reference to the drawings. A rotary frame having a fan shape as a whole is provided, an arcuate groove rail 1a is formed on the periphery of the rotating frame, and A groove plate 2 is provided protruding from the inner side of the center part, grooves 2a and 2b are formed on the lower side, and a bracket 4 is fixed at right angles to the mounting plate 3 of the table leg L, and a bearing hole 4a is provided at one end of the bracket 4.
The key shaft 1b of the rotating frame is fitted into the frame so as to be able to rotate left and right about this, and a wheel support plate 5 is fixed to the other end of the bracket 4, and a wheel support plate 5 is fixed to the other end of the bracket 4, and a wheel supporting plate 5 is fixed to the other end of the bracket 4, and a wheel supporting plate 5 is fixed to the other end of the bracket 4, and a wheel supporting plate 5 is fixed to the other end of the bracket 4. Several movable wheels 6 are attached, automatic returners 7a and 7b are attached to both sides of the bracket 4, and the tip rollers 9a and 9b of these arms 8a and 8b are respectively formed in the groove plate 2. A rotating frame formed by slidably fitting into the grooves 2a and 2b formed in the circular arc-shaped groove rail 1a) is attached to the bracket 4.
The table leg mounting plate 3 is fixed to the back surface of the table top plate T so as to coincide with the center line of the table leg L.

Note that in the drawings, S represents a sofa.

(Function) Next, to explain the function of the present invention, when the table top T is manually slid from the center position (dotted chain line) shown in FIG.
Arc-shaped groove rail 1 of the rotating frame fixed to
a rotates in the direction of the arrow x, the tip roller 9a of the arm 8a of the automatic return device 7a is pushed by the inner side of the groove 2a of the groove plate 2, and the roller 9a slides within the groove 2a, so the arm 8a is not shown in the figure. It is pushed open to the position of .
Therefore, the table top T is fixed to the table legs L.
Since the top plate T slides approximately 30 degrees to the left around the key shaft 1b of the rotating frame from the position shown in FIG. You can open it and sit down easily.

When you release your hand after sitting down, the arm 8a gradually automatically returns to its original position due to the hydraulic action of the automatic return device 7a.
Since the rotating frame connected to the groove plate 2 rotates to the right, the table top T fixed to it also moves in the direction of the arrow y.
It returns in the direction of , and returns to its original position.

Furthermore, if the top plate T is moved in the right direction arrow y, the automatic return device 7b operates in the same manner as described above, and can be rotated and slid to the right. If you wish to leave your seat, you may perform the same operation as above.

(Effects of the invention) As explained above, according to the invention, in a set where an appropriate distance is set for eating and drinking between a table and a fixed sofa, the entire table can be moved by manually rotating and sliding only the table top. It is a rotating slide table that can be used in cafeterias, social clubs, etc., and is extremely convenient, allowing users to easily and easily enter and exit seats on fixed circular sofas.
