A movable stool table with a rotation control function {Having a rotation control function stool table}

The present invention relates to a movable stool table with a rotation control function, and more specifically, a rotating folding member installed between the table and the chair so that the chair can be taken out from inside the table and automatically placed inside the table after use, and cleaned. This relates to a movable stool table with a rotation control function that allows the chair to be rotated more than a certain angle during work to maintain a fixed state and to easily move the chair to the inside of the table with a one-touch method after completing cleaning work.

In general, the tables and chairs provided in a restaurant or lounge are separated from each other, so when installed in a lounge or restaurant with a lot of people, the chairs are not properly cleaned up, resulting in a crowded place and people being separated from the table. There is a lot of inconvenience in moving between chairs, and if you want to clean the floor in a place where tables and chairs are arranged, such as a restaurant or lounge, you have to put each chair on the table top and clean the floor, making it difficult for the cleaning worker to clean. There is a problem that increases the work.

In addition, if the chair is not pushed into the table after use, it interferes with the mobility of other users, resulting in the inconvenience of having to have a separate worker manually push the chair into the table to clean it up, especially in the case of a break room restaurant. This phenomenon occurs repeatedly as many users flock together, and if they trip over an unorganized chair or fall, they end up dropping the food they are holding, which is another problem that causes harm to others.

In addition, the movable stool table is composed of a chair and a table as one piece, so when the chair is taken out of the table and used, then when you get up from the chair, it is automatically positioned inside the table, making it easy to organize the chair. However, these portable stool tables also had the inconvenience that cleaning work had to be done after removing the chair to the outside of the table and fixing it with a weight or string.

As related prior art, Patent No. 1180862 (Automatic chair folding device for a chair-integrated table) and Patent No. 1090420 (Automatic chair folding device for a chair-integrated table) have a structure that automatically rotates and folds by the elastic force of a spring. When cleaning the inside of the table, it is not only difficult to clean due to the automatically folded chair, but to solve this problem, the worker must pull the chair out of the table and then hold it with their hands or use a weight or string to prevent the table from automatically folding inward during the cleaning work. There were problems such as fixing chairs, which reduced work efficiency and increased worker fatigue.

In order to solve the above problems, the present inventor patented patents No. 1479865 (table with integrated folding chair with reinforced rotation function), No. 1543553 (table with integrated folding chair with easy rotation force adjustment), and No. 1691749 (table with integrated folding chair with easy to assemble function). As described in the table (integrated folding chair with support), when using the chair, the chair is automatically folded when rotated according to the angle of use, and when the chair is rotated beyond the angle of use, the chair can be kept fixed to the outside of the table. It is designed to make cleaning work easy, but

In the above prior arts, the assembly structure and process are complicated because the operating block fixed to the support of the table is screwed or a locking groove is formed in the frame and the operating block is fixed by hanging a pin. In order to put the chair inside the table, it must be pushed in the direction of the table, but this requires a lot of hand movement by the operator, and problems such as the chair not going inside the table due to the difference in pushing force or moving at too fast a speed and causing shock are caused. As a result, we aim to solve this problem through the present invention.

The present invention was devised to solve the above problems. By constructing the conventional fixed operating block in a non-fixed manner, the cumbersome work of fixing the operating block is eliminated, and the chair can be easily folded with one touch to place the chair inside the table. The purpose is to provide a portable stool table that can be moved.

In addition, a speed control member is installed between the fixing bracket and the housing stopper to control the speed at which the chair returns to the inside of the table, and the return speed of the chair is varied for each section to provide a movable stool table that minimizes the shock generated during the folding process. There is another purpose.

The present invention relates to a movable stool table in which a support is connected horizontally to the support angle of the table and a rotating folding member is installed at the front end of the support so that the connected chair can be automatically folded inside the table. The rotating folding member includes: A fixing bracket fixed to one side of the support, a rotating housing installed inside the fixing bracket and connected to the chair, and a housing that is fitted and coupled to the upper and lower sides of the rotating housing and has a pin coupling hole eccentric from the inner center. It consists of a stopper, an eccentric shaft pin installed perpendicularly to the pin coupling hole of the housing stopper, and an eccentric operating member that is connected to the eccentric shaft pin and automatically folds by an elastic pulling action when the rotating housing rotates. ; is an operating table coupled to the eccentric shaft pin and formed with a head, a spring inserted on the axis of the operating table and one side supported by the head, and the operating table and the spring are inserted so that the guide surface of the operating block is connected to the rotating housing by the spring. It is characterized in that it consists of an operating block that is in close contact with the rotating housing and rotates, and the pressing portion of the operating block is supported on the inner wall of the support by the pulling action of the eccentric shaft pin to generate a compressive force on the spring.

The present invention not only allows the chair to automatically fold inside the table through the rotating folding member, but also remains fixed to the outside of the table during cleaning, which has the effect of facilitating cleaning inside the table without being disturbed by the chair. there is

In addition, by constructing the operating block in a non-fixed manner, cumbersome assembly processes such as screw and pin assembly are omitted, which has the effect of simplifying manufacturing.

In addition, when cleaning, if the chair is fixed and slightly pushed with one touch, the fixed state is released by the elastic force of the spring and the chair moves inside the table, making work easier.

In addition, a speed control member is further installed between the fixing bracket and the housing stopper to control the speed at which the chair returns to the inside of the table, and the return speed of the chair is varied for each section, which has the effect of minimizing the shock generated during the folding process.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. Also, in describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

As shown in FIG. 1, the present invention is a chair in which a support 120 is horizontally connected to the support angle 110 of the table 100 and a rotating folding member 200 is installed and connected to the distal end of the support 120 ( 300) relates to a movable stool table that can be automatically folded inside the table 100.

The rotation folding member 200 of the present invention is installed between the connection frame 310 of the chair 300 and the support 120 supporting the table 100, and has one side of the support 120. A fixing bracket 210 is fixedly installed, a rotating housing 220 is installed on the inside of the fixing bracket 210 and connected to the chair 300, and the rotating housing 220 is fitted and coupled to the upper and lower sides of the rotating housing 220, respectively. A housing plug 230 having a pin coupling hole 232 eccentric from the center, an eccentric shaft pin 240 installed perpendicular to the pin coupling hole 232 of the housing plug 230, and the eccentric shaft pin 240. ) is connected to the eccentric operating member (400) and is automatically folded by an elastic pulling action when the rotary housing (220) rotates;

The eccentric operating member 400 is coupled to the eccentric shaft pin 240 and is fitted with an operating table 410 having a head 411, and is fitted on the axis of the operating table 410 so that one side is attached to the head 411. The supported spring 420, the operating table 410, and the spring 420 are inserted so that the guide surface 431 of the operating block 430 is in close contact with the rotating housing 220 by the spring 420 and the rotating housing ( As 220 rotates, the pressing portion 432 of the operating block 430 is supported on the inner wall of the support 120 by the pulling action of the eccentric shaft pin 240, thereby generating a compressive force on the spring 420. It is characterized by consisting of ;.

The eccentric operating member 400 of the present invention is a technology whose main feature is that the operating block 430 is installed on the support 120 in a non-fixed manner. In the case of the prior art registered by the present inventor (Patent Nos. 1479865, 1543553, and 1691749), all of these operating blocks are fixed, so there was a cumbersome assembly process to fix the operating blocks, and the chair was fixed. In order to put the chair inside the table in the normal state (during cleaning work), it must be pushed in the direction of the table. This requires a lot of hand movement by the worker, and due to the difference in pushing force, the chair does not go inside the table or moves at too fast a speed. There was a problem such as giving an impact, so by constructing the operating block 430 of the present invention in a non-fixed manner, the cumbersome work of fixing the operating block 430 is eliminated, and the chair 300 can be folded in a one-touch manner without difficulty. The chair 300 can be moved inside the table 100.

The eccentric operating member 400 of the present invention consists of an operating table 410, a spring 420, and an operating block 430. The operating table 410 is coupled to the eccentric shaft pin 240, and as the rotating housing 220 rotates, the end of the operating table 410 is connected to the eccentric shaft pin 240 by the eccentric shaft pin 240 fixed to the housing cap 230. It is pulled while drawing a rotation radius of (240). And the spring 420 is configured to generate a pulling force in the direction of the table 100 when the chair 300 is taken out from the table 100, and the inner side of the operating block 430 and the head 411 of the operating table 410 ) are each supported and have an elastic effect. The operating block 430 has a guide surface 431 in close contact with the outer peripheral surface of the rotating housing 220 due to the elastic action of the spring 420, and the pressing portion of the operating block 430 is pressed by the pulling action of the eccentric shaft pin 240. It is configured so that the chair 300 can be returned to the inside of the table 100 by generating a compressive force of the spring 420 while the support 432 is closely supported in the direction of the inner wall of the support 120.

The operating block 430 has an operating hole 433 through which the operating table 410 can be inserted, and a spring insertion portion with a larger diameter than the operating hole 433 in the direction in which the spring 420 is supported. (434) is formed so that the spring 420 can be supported within the operating block 430. In addition, the guide surface 431 of the operating block 430 is formed in an arc shape corresponding to the outer peripheral surface of the rotating housing 220, so that the guide surface 431 can be entirely adhered to the outer peripheral surface of the rotating housing 220. .

In addition, the pressing portion 432 of the operating block 430 is formed to protrude further in the direction in which it is pressed against the support 120, so that it comes into direct contact with the support 120 even at the beginning when the pulling action of the eccentric shaft pin 240 is performed, thereby pressuring the spring 420. ) so that the chair 300 can be returned by the elastic pulling action.

The eccentric operating member 400 of the present invention has a fixing effective angle (a) at which the rotating housing 220 can be fixed by the pulling direction of the eccentric shaft pin acting in the support direction of the pressing part 432, and the fixing effective angle When the rotary housing 220 is further rotated at a certain angle while fixed at (a), the pulling direction of the eccentric shaft pin 240 becomes the opposite direction to the support direction of the pressing unit 432, temporarily pressurizing the pressing unit 432. The chair 300 is automatically folded inside the table 100 by the elastic force of the spring 420, which was compressed as the support of is released, to return to its original state. It is characterized in that it operates divided into an automatic folding angle (b). In this way, the pulling direction of the eccentric shaft pin 240 varies depending on the effective fixing angle (a) and the automatic folding angle (b), so that if the chair 300 is taken out and fixed for cleaning work and slightly pushed in a one-touch method, the spring ( As the fixed state is released by the elastic force of 420, the chair 300 moves inside the table 100.

Below, the operating process of the rotation folding member 200 according to the present invention will be described in detail through the drawings.

Figure 5 shows the first state in which the chair 300 is located inside the table 100, and since the eccentric shaft pin 240 is located closest to the operating block 430, the pressing portion 432 of the operating block 430 is supported ( It is not in close contact with the inner wall of 120) and the spring 420 is also exerting only a slight compressive force.

Then, as shown in FIG. 6, when the chair 300 is taken out to the outside of the table 100, the rotating housing 220 rotates along the connecting frame 310 of the chair 300, and the position of the eccentric shaft pin 240 moves to the turning radius. At this time, the operating block 430 moves in the rotation direction and is in contact with and supported by the inner wall of the support 120. When the rotation housing 220 is further rotated in this state, the force to return to the initial state (FIG. 5) is strong due to the elastic force of the spring 420, and the user takes out the chair 300 at the desired angle and then sits down. When you use the table 100 and simply stand up from the chair 300, the chair 300 automatically moves inside the table 100.

Figure 7 shows a state in which the chair 300 is fixed to the outside of the table 100 during cleaning work by rotating the rotating housing 220 to the effective fixing angle (a). In this state, the chair 300 is taken out so that the cleaning tool can easily enter and exit the lower part of the table 100, not at the angle at which the chair 300 is used. In other words, when the rotary housing 220 is rotated to the fixed effective angle (a), the compression state of the spring 420 is maximized and strongly presses the operating block, but the pulling angle of the eccentric shaft pin 240 is close to a straight line. The chair 300 is fixed by maintaining the press portion 432 in a somewhat supported state without strongly pushing the support 120.

Figure 8 is a diagram showing a state in which the fixed state is temporarily released by slightly pushing the chair 300 outward after the cleaning work is completed. Figure 8 shows that the eccentric shaft pin 240 is operated at the automatic folding angle (b) by further rotating the rotary housing 220 at the fixed effective angle (a), and the pulling direction of the eccentric shaft pin 240 is the pressing portion ( As the direction is opposite to the support direction of 432, the pressing portion 432 temporarily falls away from the inner wall of the support 120.

When time passes after letting go of the hand in the state of FIG. 8, the chair 300 is automatically folded inside the table 100 by the elastic force of the compressed spring 420, as shown in FIG. 9. That is, the rotating housing 220 rotates without going through the fixed state of FIG. 7 due to the strong return force of the spring 420.

Figures 8 and 9 are made up of one connection operation, and after completing the cleaning work, when the chair 300 is slightly pushed in the outer direction rather than the inner direction of the table 100, the chair 300 is automatically folded inside the table 100. will be.

In addition, the present invention further installs a speed control member 500 between the fixing bracket 210 and the housing stopper 230 to fix the rotating housing 220 and the housing stopper 230 to the fixing bracket 210 and to use the rotating housing ( By adjusting the return rotation speed of 220, the speed at which the chair 300 moves inside the table 100 during automatic folding can be adjusted.

The speed control member 500 is; 10 to 11, a fixing screw 510 is inserted into the hollow portion 211 of the fixing bracket 210, and the fixing screw 510 is screwed in the center and has a pin hole 521 at an eccentric position. ) is formed on the operating disk 520, and a friction pin 530 that is inserted into the pin hole 521 and has one side in close contact with the contact surface 234 of the housing cap 230.

The speed control member 500 is controlled by speed control as the contact surface 234 of the friction pin 530 and the housing stopper 230 rub against each other. As shown in the drawing, the housing stopper is in contact with the friction pin 530. When the contact surface 234 of 230 is inclined, the frictional force of the friction pin 530 varies depending on the rotation section of the rotating housing 220, and the return rotation speed may change.

That is, the speed of the chair 300 folded inside the table 100 moves quickly up to a certain section and moves slowly at the last part where the chair 300 completely enters the inside of the table 100, so that the chair 300 moves along the table. (100) It is designed to allow rapid folding inward, while moving slowly at the end of the folding process to prevent shock, noise, and breakdown.

In the above, the present invention has been described with reference to the above embodiments, but of course, various modifications are possible within the technical scope of the present invention.
