Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates, in general, to a collapsible chair with a table and, more particularly, to a collapsible chair having a table and designed to be selectively used as a chair, a leisure table with chairs, or an indoor simple table with chairs, thereby being conveniently used for a variety of purposes, the collapsible chair, with the table, also being designed to be convenient to users while carrying or storing it, and requiring only a small area while being used or stored.




2. Description of the Prior Art




A collapsible chair, comprising a plurality of legs, or front, rear, left and right legs, has been proposed and used. In the conventional collapsible chair, the front, rear, left, or right legs cross each other into a front, rear, left or right X-shaped collapsible leg frame. The above leg frames are also coupled to each other at their upper and lower ends using a plurality of front and rear supports and a plurality of front and rear connectors, thus forming a collapsible chair framework. Two back support columns are mounted to the two rear support and the two rear connectors provided at the rear leg frame and supports a back support member. In addition, a seat member is supported by the four connectors of the collapsible framework.




While designing such conventional collapsible chairs, the most important objective is to allow a chair to be easily foldable, thereby being easily and conveniently carried by users and being effectively stored within a limited area. Several types of collapsible chairs, individually having a structure capable of accomplishing the above-mentioned objective, have been proposed and used.




However, such conventional collapsible chairs are problematic in that they are designed to be only used as collapsible and portable chairs, thus being limited in their use.




When it is necessary to use such a collapsible chair with a table, a user has to purchase and carry a separate table in addition to the collapsible chair. This is inconvenient to the user while carrying or storing the table along with the collapsible chair.




In an effort to overcome such a problem experienced in the conventional collapsible chairs, a collapsible leisure table, made of a plastic material and integrated with a plurality of collapsible plastic chairs, has been proposed and somewhat widely used. However, such a collapsible leisure table is problematic in that it is very difficult to carry the table because the table is very heavy and has a large size and volume even when the table is fully collapsed. Due to the large size and volume of the fully collapsed table, it is also difficult to store the table within a limited area. Another problem, experienced in the above collapsible leisure table, resides in that the table is somewhat expensive, thus failing to be generally used.




SUMMARY OF THE INVENTION




Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a collapsible chair, which has a table and is designed to be selectively used as a chair, a leisure table with chairs, or an indoor simple table with chairs, thereby being conveniently used for a variety of purposes.




Another object of the present invention is to provide a collapsible chair, which has a table and is designed to be easily collapsible, thus being convenient to users while carrying or storing it, and requiring only a small area while being used or stored.




In order to accomplish the above objects, the present invention provides a collapsible chair, comprising: two or more collapsible chair units arranged abreast on the chair with a gap being defined between the chair units; a rear vertical guide column positioned in the back of the inside back support column of each collapsible chair unit while extending in parallel to the back support column, the guide column being fixed to the inside one of two rear supports, with the collapsible chair units being coupled to each other into the collapsible single body by two auxiliary connectors, the two auxiliary connectors being individually mounted to the top portion of both the inside back support column and an associated vertical guide column of each of the collapsible chair units; a movable guide member received in each of the guide columns in a way such that the guide member is movable in a vertical direction under the guide of the guide column, with a table being movably coupled to the outside end of the guide members of two collapsible chair units in a way such that the table is rotatable around the two guide members forwardly or backwardly; two front vertical columns individually provided at the inside corner of the front portion of each collapsible chair unit, thus supporting the front portion of the table when the table is positioned horizontally; and an extension provided at each of the two auxiliary connectors so as to allow the two auxiliary connectors to have the same height as that of the two front vertical columns, thus supporting the rear portion of the table when the table is positioned horizontally.

DESCRIPTION OF THE PREFERRED EMBODIMENTS





FIGS. 1

to


6


show a collapsible chair with a table in accordance with the primary embodiment of the present invention. As shown in the drawings, two collapsible chair units


10


and


10


′ are provided at both sides of the collapsible chair of this invention and are integrated with each other into a collapsible single body. Each of the two chair units comprises a plurality of legs, or two front, two rear, two left and two right legs


2


,


4


,


6


and


8


. In the collapsible chair, the two front, rear, left, or right legs


2


,


4


,


6


,


8


cross each other into a front, rear, left or right X-shaped collapsible leg frame. The above leg frames are also coupled to each other at their upper and lower ends using a plurality of front and rear supports


12




a


,


12




b


,


12




c


and


12




d


and a plurality of front and rear connectors


14




a


,


14




b


,


14




c


and


14




d


, thus forming a collapsible chair framework. Two back support columns, or first and second back support columns


15


and


16


are held by the two rear supports


12




c


and


12




d


and the two rear connectors


14




c


and


14




d


which are provided at the rear leg frame and supports a back support member


19


thereon. In addition, a seat member


18


is supported by the four connectors


14




a


,


14




b


,


14




c


and


14




d


of the collapsible chair framework.




In the above chair, the two collapsible chair units


10


and


10


′ are arranged at both sides of the chair while being spaced apart from each other by a distance and are integrated with each other into a collapsible single body using two collapsible X-shaped intermediate frames


3


and


5


.




In order to assemble the two collapsible chair units


10


and


10


′ into a collapsible single body, a rear vertical guide column


21


is positioned in the back of the second back support column


16


of each chair unit


10


,


10


′. The above guide column


21


extends in parallel to the column


16


. The above guide column


21


is fixed to the rear support


12




d


of the rear leg frame. The two chair units


10


and


10


′ are coupled to each other by two auxiliary connectors


25


which are individually mounted to the top portion of each back support column


16


and an associated vertical guide column


21


.




A movable guide member


22


is received in each of the guide columns


21


in a way such that the guide member


22


is movable in a vertical direction under the guide of the guide column


21


. A table


30


is movably coupled to the outside end of the two guide members


22


in a way such that the table


30


is rotatable around the two guide members


22


forwardly or backwardly.




The two auxiliary connectors


25


individually have an extension


25




a


. Due to the extensions


25




a


, the two auxiliary connectors


25


have the same height as that of two front vertical columns


26


. The two front vertical columns


26


are individually provided at the inside corner of the front portion of each collapsible chair unit


10


,


10


′. Therefore, the two extensions


25




a


of the auxiliary connectors


25


and the two front vertical columns


26


support the four corners of the table


30


horizontally.




The table


30


has a horizontal bar


32


, of which both ends meet the two guide columns


21


at right angles. The two guide members


22


are brought into slidable engagement with the horizontal bar


32


of the table


30


in a way such that the guide members


22


are movable in opposite directions along the horizontal bar


32


when the collapsible chair is opened or closed.




An elastic support wire


35


is horizontally provided on the rear edge of the table


30


. When the table


30


is fully collapsed into a vertical position, the above support wire


35


is locked to the locking holes


25




b


formed at the two auxiliary connectors


25


, thus holding the table


30


in the vertical position without allowing the table


30


to be movable.




A locking cap


27


is fitted over the top end of each front vertical column


26


, while the table


30


has a locking slot


37


at each side edge thereof at a position corresponding to each of the caps


27


. Therefore, when the front portion of the table


30


is horizontally held on the two front vertical columns


26


, the two locking caps


27


are fitted into the two locking slots


37


, thus stably supporting the front portion of the table


30


in the horizontal position.




A net bag


40


, which is opened at the top, is provided at the gap defined between the two collapsible chair units


10


and


10


′. The above net bag


40


has four hook rings


42


at the four corners of its top edge. Of the four hook rings


42


, two front rings


42


are removably caught by the two front vertical columns


26


, while the two rear rings


42


are removably caught by the two second back support columns


16


, thus being removably attached to the collapsible chair of this invention.




As shown in

FIG. 10

, showing another embodiment of this invention, an arm rest


50


may be attached to the outside portion of each chair unit


10


,


10


′.




In the drawings, the reference numeral


7


denotes an auxiliary coupling member which is provided at each of the two front vertical columns


26


and the two back support columns


16


. The four auxiliary coupling members


7


are used for hinging the two X-shaped collapsible intermediate leg frames


3


and


5


to the supports


12




b


and


12




d


of the two chair units


10


and


10


′, respectively.




The operational effect of the above collapsible chair with the table will be described hereinbelow.




In order to move the table


30


from a vertical closed position to a horizontal position, or a usable position, the two guide members


22


, slidably assembled with the horizontal bar


32


of the table


30


, are moved upwardly along the two guide columns


21


until the two guide members


22


come into contact with the two auxiliary connectors


25


.




In such a case, the table


30


is moved upwardly along with the guide members


22


.




After the table


30


is completely moved upwardly along with the guide members


22


, the horizontal bar


32


is rotated forwardly around the two guide members


22


, thus being rotated forward and being positioned horizontally.




When the table


30


is positioned horizontally as described above, the two rear corners of the table


30


are supported by the extensions


25




a


of the two auxiliary connectors


25


, while the opposite edges of the front portion of the above table


30


are held on the top ends of the two front vertical columns


26


. Since the height of the two extensions


25




a


is equal to that of the two front vertical columns


26


, the table


30


accomplishes a desired horizontality.




In such a case, the locking cap


27


, fitted over the top end of each front vertical column


26


, is fitted into an associated locking slot


37


formed on the front portion of the table


30


. Therefore, the table


30


is stably held on the two front vertical columns


26


while being almost completely prevented from being undesirably moved to the front, back, left or right.




As described above, the table


30


is horizontally placed at the gap between the two collapsible chair units


10


and


10


′. The collapsible chair, with the horizontally positioned table


30


, may be used for a variety of purposes.




When it is necessary to use the collapsible chair with the table


30


being fully closed, the table


30


is moved from the above-mentioned horizontal position to the vertical position. In order to move the table


30


from the horizontal position to the vertical position, the two locking caps


27


of the front vertical columns


26


are forcibly and manually opened to be moved away from each other, thus releasing the two locking slots


37


of the table


30


from the caps


27


.




The horizontal bar


32


of the table


30


is rotated backwardly around the two guide members


22


, thus allowing the table


30


to have a vertical position.




The table


30


in the vertical position is, thereafter, moved downwardly. In order to move the vertically positioned table


30


downwardly, the two guide members


22


, engaging with the horizontal bar


32


, are moved downwardly along the two guide columns


21


until the table


30


is fully closed.




When the table


30


is fully moved downwardly, the elastic support wire


35


of the table


30


is guided by the locking holes


25




b


of the two auxiliary connectors


25


, thus being brought into engagement with the two auxiliary connectors


25


.




The above table


30


is thus held by the two guide members


22


at the horizontal bar


32


and is held by the auxiliary connectors


25


at the support wire


35


. Therefore, the table


30


in the vertical closed position is stably held without being undesirably moved to the front or back.




When the two collapsible chair units


10


and


10


′ are fully opened with the table


30


being fully closed as described above, the collapsible chair of this invention is used as a double chair without having a table.




In addition, the net bag


40


, opened at the top, is provided at the gap defined between the two chair units


10


and


10


′. The above net bag


40


has four hook rings


42


at the four corners of its top edge and is removably held by both the front vertical columns


26


and the back support columns


16


at the four hook rings


42


. The above net bag


40


may be preferably used as a garbage bag or a container capable of receiving food or a variety of necessaries therein when the chair is used outdoors.




When the arm rest


50


is attached to the outside portion of each chair unit


10


,


10


′ as shown in

FIG. 10

, the chair of this invention may be more convenient to users.




When it is necessary to fully fold the collapsible chair of this invention prior to carrying or storing the chair, the two chair units


10


and


10


′ are easily collapsed at the collapsible intermediate leg frames


3


and


5


provided between the two chair units


10


and


10


′.




When collapsing the chair of this invention, the two guide members


22


of the guide columns


21


, provided at the rear portion of the chair, are moved in opposite direction so as to commonly reach the center portion of the horizontal bar


32


of the table


30


as shown in FIG.


8


. Therefore, it is possible to reduce the size and volume of the chair when the chair is fully collapsed.




Such a small-sized collapsed chair is convenient to users while carrying, storing or transporting the chair.




As described above, the present invention provides a collapsible chair with a table. The collapsible chair is designed to be selectively used as a chair, a leisure table with chairs, or an indoor simple table with chairs, thereby being conveniently used for a variety of purposes. The collapsible chair of this invention also has a net bag which may be preferably used as a garbage bag or a container capable of receiving food or a variety of necessaries therein when the chair is used outdoors. Due to the net bag, the collapsible chair of this invention is more convenient to users.




The above chair, with the table, is designed to be easily collapsible, thus being convenient to users while carrying or storing it, and requiring only a small area while being used or stored.




Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. For example, a part of the construction of the two collapsible chair units may be changed without affecting the functioning of this invention. In a detailed description, the structure of the leg frames and the configuration of both the seat member and the back support member may be somewhat freely modified without affecting the functioning of this invention.
