Description

Chair combination structure of chair integrated table {CHAIR FOLDING DEVICE FOR TABLE ATTACHED CHAIR}

The present invention relates to a chair coupling structure of a chair-integrated table, and more particularly, in providing a chair coupling structure for a table having a structure in which a chair is automatically aligned in an initial state when the chair is raised after using the chair. By improving the convenience of assembly and parts replacement by simplifying, it can increase the price competitiveness, greatly reduce the cause of breakdown, and by removing the weight from the chair, the chair's support leg is raised to a certain height from the ground. It relates to a chair coupling structure of the chair-integrated table to facilitate the folding operation of the chair and to facilitate the cleaning work.

As is well known, tables are used for various purposes, such as tables for various work tables, meetings, joint classes, and shared tables in schools, government offices, and companies.

A typical table consists of a top plate made of a plate-shaped plate and a frame having a single or multiple legs for supporting the plate, and on both sides of the table, a number of separate chairs for user sitting are used. Will be.

In this case, chairs arranged on both sides of the table are usually disposed in a state separated from the table.

As such, the chair separated from the table causes various problems in use because it moves separately from the table.

First of all, it is good to arrange the chair neatly on the bottom of the table after using the chair, but in practice, the chairs that are actually used are not well organized. If left unaligned, it was awkward to look good, so there was a need for a separate manager to arrange the chair periodically.

As such, when the table and the chair are separated, the chair is easily scattered around the table, difficult to organize and manage, and has a hassle to push the chair into the table after use to tidy it up.

In addition, when cleaning the floor, the chair should be placed on the table and cleaned and then placed back on the floor to align, which has the disadvantage of increasing the difficulty of cleaning.

Because of these problems, the chair-integrated table has a structure in which the chair is pulled out when the frame and the hinge structure are connected to the conventional table and the chair, and the chair is folded and the chair is pushed under the table when not in use. Is proposed and disclosed.

For example, Republic of Korea Utility Model No. 0311562 (published on June 15, 2003) discloses a table having a chair that is automatically folded.

The table having the chair that is automatically folded is to present the table of the structure that the chair is automatically folded when the user stands up from the chair by applying the hinge of the automatic folding structure to the table chair.

That is, according to the table having the chair that is automatically folded, it is configured to be automatically folded by a spring-loaded hinge inside the chair is automatically folded when the chair can be used more efficiently to use the space where the table is placed It is effective and offers the advantage of automatically folding the chair without touching it.

However, the structure is the auxiliary frame is coupled to the horizontal frame, the chair mounting rods on the connecting frame coupled to the hinge to the end of the auxiliary frame is composed of a structure that the weight loaded on the chair acts in the form of twisting back and forth and left and right If there is a disadvantage that the hinge portion is easily transmitted to the hinge portion by the moment force, and the hinge portion is easily damaged, and there is one mounting rod serving as a leg of the chair, which becomes a very unstable state such as shaking or twisting when weight is loaded.

In addition, the structure is a structure in which the chair is lifted up by the self-elasticity of the auxiliary frame and the connecting frame is folded, there is a disadvantage that the folding operation is not properly made when used for a long time.

On the other hand, Republic of Korea Utility Model No. 2010-5049 (2010.5.17. Disclosure) is disclosed a folding chair integrated table, Republic of Korea Patent Publication No. 2012-17489 (2012.2.29) chair connection device of the chair integrated table Is disclosed.

Among the folding chair integrated tables disclosed in Korean Utility Model No. 2010-5049, when the chair connected to the end of the horizontal support frame of the table is rotated outward and rises from the seat after use, the inside of the table is automatically moved by the elasticity of the torsion spring. By folding the chair, the chair connected to the table is always kept aligned at a certain position, which has the advantage of not having to align the chair after use.

However, when the chair is configured to automatically be folded into the table by the elasticity of the torsion spring, the end length of the torsion spring must be configured to be generally long so as to prevent the torsion spring from deviating from the connection hole during the torsional operation of the torsion spring. Due to its structural characteristics, it is very difficult to install the torsion spring by inserting it into the connection hole of the bracket and the coupling hole of the bottom of the spring installation member, which not only makes it difficult to assemble, but also rotates the chair in and outward Even when the rotating housing rotates, the disadvantages such as noise generated due to the friction of the rotating part was exposed.

In addition, the chair automatic folding structure of the chair-integrated table of Republic of Korea Patent No. 549519 (announced on February 2, 2006), the chair-integrated table of appearance type of Republic of Korea Patent No. 752676 (announced on August 29, 2007), Republic of Korea Patent No. 799188 Folding chair-integrated table of No. (2008.1.30. Notification), Folding chair-integrating table of Republic of Korea Patent No. 1067573 (Announcement on September 27, 2011), Chair of Republic of Korea Patent No. 1090420 A large number of documents, such as a chair automatic folding device of an integrated table, disclose a table having a structure capable of automatically pushing a chair under a table.

However, the technical configuration of the chair automatic folding device of the conventional chair-integrated table having the structure as described above is composed of many components to perform the folding operation, it is difficult to assemble and replace the parts, the production cost is high, the cost competitiveness There was a disadvantage in this fall, such a chair automatic folding device is fixed to the chair integral table has to be repeatedly a rotating operation as many times as the user uses the chair from time to time repeatedly had a problem that causes the occurrence of frequent failures.

Hereinafter, a chair coupling structure of a chair integrated table according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In order to explain the preferred embodiments of the present invention, the thicknesses of the lines and the sizes of the components shown in the attached drawings may be exaggerated or omitted for clarity and convenience of description, Terms to be given are terms defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator.

1 and 2 is a perspective view showing the structure of a chair integrated table according to the present invention, Figure 1 is a view showing a state in which the chair is automatically aligned inside the table before the user sits, Figure 2 is a user in the state 1 Figure is a view showing a state in which the chair is rotated outside the table to sit on the chair.

As shown in Fig. 1 and Fig. 2, the chair-integrated table according to the present invention includes a table top plate 10 made of a flat plate and a plurality of table legs 31 for supporting the table top plate 10. It includes a lower frame 30 and a plurality of chairs 20 are integrally assembled to be rotatable about the table legs 31 of the lower frame 30.

At this time, the chair 20 is fixed to the ground through the support leg 21, it is also possible to use a chair 20 having a backrest, as shown in the figure, a circular chair without a backrest (not shown) Can also be used.

In addition, although not shown, the chair 20 is supported and fixed in a structure capable of freely rotating in the desired direction on the support leg (21). This is a universal configuration that can be commonly found in conventional chairs as well as conventional chair integrated table, the detailed description thereof will be omitted.

In the chair-integrated table having the configuration as described above, when the user's weight is not applied to the chair 20, the chair 20 connects the support leg 21 and the table leg 31 of the chair 20. It is characterized by providing a structure that is lifted by its elasticity through the rotation and lifting of the rotating means 40 and folded under the table top plate 10 to be automatically aligned.

1 and 2, the chair coupling structure of the chair integrated table according to the present invention supports and fixes the bottom surface of the chair 20 to the table leg 31 through a horizontal connecting shaft 22. As the support legs 21 of the chair are interconnected, a chair integrated table is configured.

At this time, as shown in Figures 3 to 8, the rotation means 40 between the horizontal connecting shaft 22 and the table leg 31 connecting between the support leg 21 and the table leg 31 of the chair 20 Equipped)

As shown in FIG. 3, the rotating means 40 includes a rotating tube 41 having a T-shaped structure inserted into the table leg 31, and formed on the rotating tube 41 to rotate the rotating tube 41. Guide rail 42 for guiding the rotational direction and the rotational distance of the < RTI ID = 0.0 >), < / RTI > integrally protrudingly fixed on the table leg 31, and sequentially with the guide surfaces 42a, 42b, 42c, 42d of the guide rail 42. The fixed guide shaft 43 which induces the rotation and the elevating of the rotary tube 41 in contact with it, and the elasticity (compression force and elastic restoring force) inserted into the rotary tube 41 and required for the rotation and elevating of the rotary tube 41. It is composed of a spring member 44 that provides a).

That is, the horizontal connecting shaft 22 is inserted into the table leg 31 through the vertical through hole 46 of the rotating tube 41, and is inserted into the horizontal insertion hole 45 extending from the side of the rotating tube 41. One end of the fitting is connected, the table leg 31 and the support leg 21 of the chair 20 are interconnected and integrated.

In addition, the guide rail 42 formed on the rotating pipe 41 has a downward curved guide surface 42a, a vertical straight guide surface 42b, and a horizontal straight line, which are required for rotating and descending the rotating pipe 41. The guide surface 42c and the upward curved guide surface 42d are formed as one continuous closed surface.

That is, as shown in the figure, the lower curved guide surface 42a and the upward curved guide surface 42d meet to guide the lower portion of the long rail-shaped guide rail 42 that can guide the fixed guide shaft 43. Starting at the lower end of the guide rail 42, the downward curved guide surface 42a and the upward curved guide surface 42d are formed at the same inclination to a certain height, and then gradually By forming the guide rail 42 of the curve required for the rotation and lifting of the rotating tube 41.

Subsequently, when the downward curved guide surface 42a reaches a predetermined height while drawing the curved guide rail 42 upward, the vertical straight guide surface 42b guides vertically by a predetermined height (or length). The rail 42 is formed, and at the point where the vertical straight guide surface 42b ends, the horizontal straight guide surface 42c horizontally forms the guide rails 42 by a predetermined length L, and the upward curved guide. The uppermost guide rail 42 is formed to meet the surface 42d.

At this time, the downward curved guide surface 42a constituting the guide rail 42 is as shown in FIG. 2 in an initial alignment state (state of FIG. 1) in which the chair 20 is in close contact with the table top plate 10. When the rotating tube 41 is rotated to pull out the chair 20 in the outward direction of the table top plate 10, it acts as a rotating guide surface.

In addition, the vertical straight guide surface 42b rotates the rotating tube 41 to some extent (by the length of the downward curved guide surface 42a) in order to remove the chair 20 in the outward direction of the table top plate 10. When the user is sitting on the chair while applying weight, the rotating tube 41 is momentarily downward while the support leg 21 of the chair 20 acts as a vertical downward guide surface to reach the ground.

In addition, the horizontal straight guide surface (42c) is the user's body shape and the chair 20, although the support leg 21 of the chair 20 is in contact with the ground while the user is sitting on the chair 20 The length of the horizontal straight guide surface 42c when the chair 20 is to be moved further in the outward direction to adjust the distance between the table top plate 10 and the chair 20 according to the habit of sitting on As the rotating tube 41 rotates horizontally by L), the rotating tube 41 acts as a guide surface to secure a space for moving the chair 20.

In addition, the upward curved guide surface 42d is an initial alignment state in which the chair 20 is in close contact with the table top plate 10 when the user does not use the chair 20 while sitting in the chair 20. (Or, the chair is pushed back to the bottom of the table top plate) is automatically returned to the bar, at this time, the rotating tube 41 acts mainly as a guide surface for upward rotation.

Of course, when the chair 20 is returned to the initial alignment state as described above, the fixed guide shaft 43 for guiding the upward rotation of the rotating tube 41 is necessarily guided only along the upward curved guide surface 42d. In some cases, the fixed guide shaft 43 may be sequentially guided along the vertical straight guide surface 42b and the downward curved guide surface 42a.

At this time, as shown in Figures 1 and 2, formed on the rotating tube 41 is inserted into the table leg 31 in accordance with the position of the table leg 31 is arranged on the bottom surface of the table top plate 10. The direction of the rotation curve of the guide rail 42 to be changed.

This is because the rotation direction of the table leg 31 is different depending on the installation position of the chair 20, so the rotation curve design of the guide rail 42 on the rotation pipe 41 in accordance with the rotation direction of the chair 20 It will be formed by adjusting naturally.

On the other hand, the design elements related to the shape and size of the guide rail 42, etc. can be simply changed to various shapes and sizes in consideration of the swing width and the lifting height of the chair by the rotating tube 41, which is It will be appreciated that the design is simple due to the needs of the manufacturer.

The spring member 44 inserted into the pivot tube 41 is disposed between the upper portion of the fixed guide shaft 43 formed on the table leg 31 and the locking jaw 47 formed on the upper portion of the pivot tube 41. As described above, it serves to provide elasticity (compression force and elastic restoring force) required for rotation and lifting of the rotating pipe 41.

At this time, the spring type and the size of the spring for the elasticity and durability of the spring member 44 is only an optional design matter of the manufacturer according to the product to be designed, sufficient for the rotation and lifting of the rotating tube 41 Naturally, the spring member 44 having rigidity is selected.

On the other hand, when the guide surface (42a, 42b, 42c, 42d) of the guide rail 42 is formed as described above, the support leg 21 of the chair 20 is lifted by the restoring force of the spring member 44. Since the rotating tube 41 is rotated along the guide rail 42 while the chair is automatically returned to the initial state, the process is instantaneously and collectively performed, so that the chair can be rotated even when the chair is not completely out of the chair. As a result, inconveniences that may cause interference problems due to the contact between the user and the chair exist.

Accordingly, the present invention, as shown in Figures 10 to 12 in order to prevent the inconvenience as described above, in order to prevent the problem of interference due to the contact between the user and the chair that can occur during the automatic return process of the chair 20 in advance. As a part of this, the guide rail 42 has a structure in which a horizontal guide jaw 42e is provided on the upward curved guide surface 42d.

The guide jaw 42e is for limiting the automatic rotation of the rotating tube 41, as shown in Figs. 11 and 12, the fixed guide by the elastic force of the spring member 44 the moment the user leaves the chair As the shaft 43 moves along the downward curved guide surface 42a, the chair 20 is naturally lifted as the pivot tube 41 rises.

Then, as the fixed guide shaft 43 continuously reaches the rotation stage, which is the next stage, the fixed guide shaft is positioned on the guide jaw and the rotation of the rotation tube 41 is restricted.

When the movement is restricted while the fixed guide shaft 43 is in contact with the horizontal guide jaw 42e as described above, the chair 20 is lifted from the ground, that is, maintained.

Therefore, the user can completely escape from the chair 20 in the state in which the rotation is stopped while the chair 20 is lifted up, and the user pushes the chair by applying a little force while the chair 20 is completely removed from the chair 20. As the fixed guide shaft 43 spans the main surface, the guide jaw 42e is out of the guide jaw 42e, and the fixed guide shaft 43 is upwardly curved by the elastic force of the spring member 44. As the downward rotation of the chair 20 is guided along the chair 20, the chair 20 is able to return to an initial state.

On the other hand, the configuration of the rotation means 40 may vary depending on the installation position of the spring member 44.

That is, as shown in Figures 13 to 15, look at the configuration of the rotating means 40 according to another embodiment of the present invention.

The rotation means 40 according to another embodiment of the present invention shown in FIG. 13 is compared with the rotation means 40 shown in FIGS. 3 and 9 when the insertion position of the spring member 44 is changed, Accordingly, in the configuration for compressing and fixing the spring member 40 will have different embodiments.

In other words, in the rotating means 40 according to another embodiment of the present invention, as can be confirmed in more detail with reference to FIGS. 14 and 15, the spring member 44 of the guide rail 42 formed in the rotating pipe 41 is included. It is located downward.

That is, a fixed step 48 is formed on the inner circumferential surface adjacent to the lower side of the guide rail 41 formed on the rotating tube 41, the fixed step 48 is in contact with the upper end of the spring member 44 to press It will play a role.

In addition, the high intelligence shaft 49 protrudes from the fixed guide shaft 43 formed on the table leg 31 at a predetermined distance downward, and the high information shaft 49 supports and fixes the lower end of the spring member. It will play a role.

In other words, the spring member 44 is inserted and seated between the fixed stepped portion 48 formed on the inner circumferential surface of the rotating tube 41 and the high information shaft 49 formed on the table leg 31, thereby providing a spring member 44. It is to be involved in the rotation and lifting action of the rotating tube 41 through the elastic action.

At this time, the lower end portion of the rotating tube 41, the spring member 44 is inserted is formed to a sufficient length to cover the entire length of the spring member 44 so that the spring member 44 is not exposed to the outside. desirable.

In addition, the interference between the inner circumferential surface of the rotating tube 41 and the high information axis 49 protruding from the table leg 31 so that the rotating tube 41 can be smoothly moved up and down is not caused to interfere with each other. It is natural to have a sufficient gap.

Of course, as shown in Figures 11 to 15, as the installation position of the spring member 44 inserted into the rotary tube 41 is changed to the inner peripheral surface of the rotary tube 41 for the mounting of the spring member 44 The fixed step 48 is formed, and correspondingly, the guide rails 42 and the guide surfaces 42a, 42b, 42c, and 42d except for the structural difference in which the high information axis 49 is formed on the table leg 31 are correspondingly formed. The configuration such as the guide jaw 42e and the like is formed in the same manner as the configuration of the rotation means 40 shown in Figs.

Therefore, the detailed description of the guide rail and the guide surface formed on the rotating means 40 according to another embodiment of the present invention shown in Figure 11 to 15 will be omitted.

Looking at the operation relationship for the chair coupling structure of the chair integrated table according to the present invention having the configuration as described above are as follows.

At this time, in the description of the operating relationship of the present invention, several modified embodiments are shown as described above, which will be described with reference to the rotation means 40 shown in FIGS. 3 and 9.

According to the present invention, first, when the user takes out to sit on the chair 20 in a state in which the chair 20 is in close contact with the table top plate 10 or located on the bottom, a supporting leg configured at the bottom of the chair 20 ( In order to prevent the 21 from being caught on the ground and hinder the rotation operation, the support leg 21 of the chair 20 is configured to float in the air in a state spaced apart from the ground (h). Then, when the weight is loaded on the chair 20, the supporting leg 21 is lowered to be in contact with the ground.

That is, as shown in FIG. 1, in the initial state (that is, the normal state) in which the chair 20 is aligned under the table top plate 10, the support leg 21 floats in the air in a state of being spaced apart from the ground h. Will remain in place.

As shown in FIGS. 5 and 6, the rotation tube 41 receives elasticity by the spring member 44 located in the rotation tube 41, and the rotation tube 41 is centered on the fixed guide shaft 43 at the table leg 31. This is possible because it is moving upward.

When the pivoting tube 41 is lifted about the fixed guide shaft 43 with elasticity according to the expansion of the spring member 44, and thus the support leg 21 connected to the pivoting tube 41 is lifted together. Since the chair 20 is naturally lifted from the ground, the supporting leg 21 of the chair 20 is spaced apart from the ground (h), and the chair 20 is on the table top 10. Folding operation (that is, rotational movement) entering or exiting the bottom is smoothly performed.

When the user intends to use the chair while maintaining the initial alignment of the chair 20 as described above, as shown in FIGS. 2, 7 and 8, the user places the chair 20 on the tabletop ( 10) After the rotational movement in the outward direction from the bottom, if the seating space is secured, the user sits on the chair 20 to apply weight.

When the user's weight is applied to the chair 20, the pivot tube 41 rotates downward along the guide rail 42 about the fixed guide shaft 43 and at the same time, the spring member 44 is compressed to the maximum. Will be. At this time, the support leg 21 of the chair 20 is in contact with the ground is to stably support the chair 20.

As such, the present invention, as shown in the drawings, the chair 20 is normally in the bottom surface of the table top plate 10 or kept in close contact, and when the user pulls out the chair to sit on the chair 20, the table legs As the spring member 44 inserted into the rotating tube 41 installed in the 31 is compressed, elasticity (that is, force) is stored, and when the user leaves the chair 20, the restoring force of the spring member 44 is applied to the spring member 44. By the support leg 21 of the chair 20 is automatically lifted by the rotating tube 41 is rotated to enter the bottom position of the table top plate 10 to be aligned in the initial state.

10 to 12, when the guide jaw 42e is formed on the upward curved guide surface 42d formed on the guide rail 42, the chair is lifted to an initial state. In the process of returning, the user may apply a slight external force to the chair while the chair 20 is restricted by the guide jaw 42e to release the restricted seat and enter the original bottom side of the table top plate 10.

As such, in the case of partially limiting the rotation process of the chair 20 through the guide jaw 42e in the process of returning to the initial state of the chair 20, the user and the chair may occur during the automatic return process of the chair 20. Interference due to contact of the can be prevented in advance.

On the other hand, the present invention as described above in the chair integrated table, the width of the chair 20 is rotated and folded can be variously designed and modified through the shape of the guide rail 42 formed on the rotating pipe 41 It will be appreciated that the present invention is not limited to the above-described embodiments.

In particular, the guide rails 42 formed on the rotating tube 41 are not formed only on one side of the rotating tube 41, but are formed in plural numbers to face each other on the rotating tube 41 as illustrated in FIGS. 9 and 12. By doing so, the rotation and lifting operation of the rotating tube 41 can be more stably achieved.

That is, it is natural that various modifications can be made by a person having ordinary skill in the art without departing from the technical gist of the claims related to the chair coupling structure of the chair integrated table according to the present invention. Do.
