Description

Stool table with easy rotation {Stool table with easy rotation}

In the present invention, the stool support does not cause friction on the floor and only the stool rotates in place when the stool is turned from side to side while seated on the stool in a stool-integrated table in which the stool is stored under the table, thereby generating noise. There is no floor damage to be prevented.

In general, it can be seen that when a table with separate chairs is placed in a place such as a break room or a cafeteria where people come and go, the chairs are not well organized, so the place is crowded and there is a lot of inconvenience in the passage. In addition, since the area occupied by the chair is quite large, if the operation of pushing the chair into the table is not performed, the space in which the table is placed is narrowed, thereby reducing space utilization.

Because of these problems, in a conventional school or in-house cafeteria, a chair-integrated table that limits the rotation range of the chair by connecting the connecting frame of the chair to the frame of the table with a hinge structure capable of horizontal rotation. Although proposed, in this case, in order to use the chair stored under the table, the user rotates the chair horizontally around the hinge and pulls out the chair. A table having a structure that is used in a form that is rotated and stored under the table was used.

Patent documents 1 to 5, etc. are disclosed as related prior art. These prior art are commonly hinged to a stool (chair) to a support frame of a table to allow storage and withdrawal. In the method of supporting a person's weight, it consists of a structure in which the load is transmitted to the hinge in the form of a cantilever and a structure in which one leg is attached under the stool.

In the prior art as described above, the structure in which the one leg is attached to the lower part of the stool has the advantage that it can stably support the weight and has excellent durability. When the stool is rotated in place, the lower part of the outer leg rotates while causing friction with the indoor floor, so it can damage the indoor floor.In order to prevent this, a heel made of synthetic resin is attached and used, but it rotates in place. Not only does it generate quite annoying fricatives to the ears, but also damages the heel as well as the floor material due to repetitive friction, and it is not easy to rotate the stool in place, so the seated person can freely sway the body. I couldn't even do the rotation.

In addition, in the prior art as described above, the stool's outer leg (column) can be kept in an uplifted state on the horizontal rotating frame hinged to the support frame of the table in order not to touch the bend of the stool's outer leg when not seated on the stool. The spring had to be inserted into the support pipe of one end of the horizontal rotating frame so that the assembly process for the insertion and installation of the spring was complicated, and the number of parts increased, resulting in an increase in the number of man-hours, resulting in an increase in manufacturing cost.

The present invention was conceived to solve the above problems, and the object of the present invention is to first, the rotation of the stool capable of preventing the occurrence of noise or damage to the indoor floor while allowing the free rotational operation of the one-legged stool. It is to provide an easy stool-integrated table.

Second, the present invention improves the spring installation structure to keep the stool away from the floor in a state where the stool is not seated on the stool, and reduces the number of parts to allow assembly in a simple process, thereby reducing manufacturing cost and productivity. It is to provide a stool-integrated table with easy rotation of the stool that can improve the quality.

In order to achieve the above object, the present invention is a stool-integrated table in which a horizontal rotating frame of a stool is hingedly connected to a support frame of a table so that the stool can be stored under the table and taken out to the outside, wherein the stool is The one leg that supports the weight of the seated person is kept floating on the floor by the spring when not seated, and is in close contact with the floor by the weight when seated, but the sleeve is fixed at the bottom of the one leg, and the sleeve is in close contact with the floor. The stool support is rotatably coupled to provide a stool-integrated table that allows easy rotation of the stool so that the stool can freely rotate in place even when the stool support is in close contact with the floor when seated.

In a preferred embodiment, the spring is placed on the support pipe of one end of the horizontal rotating frame, and the upper end is in close contact with the bottom of the stool so that the outer leg of the stool remains lifted from the floor when not seated, but the sleeve is in contact with the lower end of the support pipe. In addition, it serves as a stopper to limit the lifted state of the stool, so that the number of parts and assembly man-hours can be reduced.

According to an embodiment of the present invention, even if the body is rotated from side to side while seated on the stool, the stool support attached to the floor stably supports the weight, while the stool is freely rotated by a sleeve rotatably coupled to the stool support. Because the stool barim is in close contact with and fixed to the floor during this rotation operation, friction noise such as scratching or damage to the floor material does not occur, and the stool is floating. The installation structure of the spring for maintaining the state is also simplified, and the number of parts is reduced, thereby reducing the manufacturing process and the manufacturing cost of the double.

1 to 6 shows a stool-integrated table according to an embodiment of the present invention, which is connected to the support frame (F1) of the table (T) and the horizontal rotating frame (F2) of the stool (S) in a hinged manner. A stool-integrated table in which the stool (S) can be stored under the table (T) and withdrawn to the outside, and the stool (S) is the one leg (10) supporting the body weight of the seated person (a) of FIG. When not seated as in, it is kept floating on the floor by the spring 20, and when seated, it is in close contact with the floor by the weight of the seated person (not shown) as shown in FIG. 3(b), A sleeve 30 is fixed at the lower end of the outer leg 10, and a stool support 40 that is in close contact with the floor is rotatably coupled to the sleeve 30 so that the stool support 40 is in close contact with the floor when seated. Even in the state, the stool S is designed to be freely rotated in place.

In this embodiment, the spring 20 is made of a compression coil spring and is placed on the support pipe 22 at one end of the horizontal rotating frame F2, and the upper end of the spring 20 is in close contact with the bottom of the stool S so that it is not seated. The outer leg (10) of the stool (S) is kept in a lifted state from the floor, but the sleeve (30) fixed to the bottom of the support pipe (22) serves as a stopper to limit the lifted state of the stool (S). Has been.

Conventionally, the cumbersome assembly process such as having to insert the spring 20 into the support pipe 22 and insert a separate stopper ring on the upper and lower portions thereof can be omitted by the assembly method as described above. The lower end of 20) is caught on the support pipe 22 and is in close contact with the bottom of the stool (S) at the upper end of the spring (20), so there is no need for a separate stopper ring or fixing washer as described above, and the outer leg of the stool (S) After inserting the outer leg 10 into the support pipe 22 while the spring 20 is inserted in the 10, the sleeve 30 with the stool support 40 assembled at the lower end of the outer leg 10 is mounted and fixed. Since the assembly is completed as soon as possible, there is an advantage that the number of parts can be reduced as well as the assembly man-hour.

The sleeve 30 has a cylindrical upper coupling part 32 into which the lower end of the outer leg 10 is inserted, and extends downward from the upper coupling part 32, as shown in FIGS. A support coupling portion 34 having a size smaller than the outer diameter of the coupling portion 32 and into which the stool support 40 is rotatably inserted, and an elastic hook 36 formed outside the lower end of the support coupling portion 34 Consists of.

In the drawings, reference numeral 38 denotes a cutout portion for allowing the elastic hook 36 to exhibit elasticity, and reference numeral 39 denotes a reinforcing rib radially formed inside the support coupling portion 34.

The sleeve 30 is inserted and fixed to the lower end of the outer leg 10, and of course, a rivet or a fixing screw may be additionally fastened to maintain the fixed state.

The stool support 40 has an insertion tube part 44 inserted into the support coupling part 34 in the upper center of the body 42 as shown in FIGS. 4 and 5, and the insertion tube part 44 Outwardly, a reinforcing rib 46 extending to the inner surface of the body 32 is formed radially.
