[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is used to connect the seat plate of various folding tables used for leisure use, the seat plate of a stand-alone chair, and a separately manufactured cushion sheet to each other. The present invention relates to a joint structure between a seat plate and a cushion seat, and particularly to a joint structure that enables separation and connection of a seat plate and a cushion seat.

[0002]

[Prior art]

 Generally, the seat plate attached to a conventional folding table is configured to be used as a chair when opened and to be folded inside the table body when folded. Formula tables are commonly used for mobile and leisure use.

[0003]

[Problems to be solved by the invention]

 However, in such a folding table, most of the components including the seat plate are made of a resin injection material that is relatively light and excellent in strength, and the seat plate that is a component of the folding table is also made of resin. It has the disadvantage that it is hard and has a weak cushioning effect because it is made of extruded material. As a solution to these disadvantages, it is possible to carry a cushion or cushion sheet separately and lay it on a seat plate when necessary, but it is inconvenient to prepare a separate cushion or cushion sheet. It is not practical because it can be lost.

[0004] Furthermore, a method of fixing a cushion or a cushion sheet on a seat plate is conceivable. However, if the cushion is completely fixed, the cushion or the cushion may be damaged during use or become dirty when washing. The cushion must be removed from the seat plate, which is troublesome. In order to solve the conventional drawbacks, the present invention combines a separately manufactured cushion sheet on a seat plate to provide a coupling structure that facilitates the coupling and separation of the cushion sheet, and also provides a cushion sheet when the coupling is used. Due to the elasticity of the cushion itself, the seating comfort is improved, the assembly work is easy even in the manufacturing process, the cushion sheet can be easily separated when the cushion sheet is damaged or washed, and the cushion sheet can be replaced. It is intended to be able to be removed for washing.

[0005]

[Means for Solving the Problems]

 The present invention achieves the above object, and in the structure in which the cushion sheet is joined on the seat plate, a large number of through holes are formed in the seat plate, and the cushion sheet has joining holes at predetermined positions corresponding to the through holes. The coupling is inserted and coupled with the through hole and the coupling hole aligned, forming a protrusion on the outside of the upper part of the coupling, and a hole or a hook in the form of a ring on the lower part. It is formed by inserting a ring-shaped member into the hook portion.

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 to 7, the mounting structure of the cushion seat in the folding chair table according to the present invention is the mounting structure of the cushion plate of the seat plate (1) attached to the folding chair table T. Seat mounting structure A large number of through holes (10) are formed in the seat plate (1) to couple the cushion sheet (2) to the upper portion of the seat plate (1). A coupling hole (20) is formed at an arbitrary position corresponding to the hole (10), for example, at each of the four corners, and the coupling device (3) is put together with the through hole (10) and the coupling hole (20). It is configured by inserting and connecting.

[0007] The coupling device (3) has a protruding portion (4) formed outside the upper portion, and a hole or a ring-shaped hook portion (5) formed at the lower portion, and the hook portion (5). Is provided with a ring-shaped member (6) made of an elastic material such as rubber. At this time, the protruding portion (4) located at the upper portion is made larger than the coupling hole (20) of the cushion sheet (2), and the lower portion forming the hook portion (5) is formed at the coupling hole (20) of the cushion sheet (2). 20) and the through hole (10) of the seat plate (1). The ring-shaped member (6) to be inserted into the hooking portion (5) is made of an elastic material such as rubber and is formed sufficiently long. As shown in FIGS. 2 and 3, the coupling hole of the cushion sheet (2) is formed. (20), through the through hole (10) of the seat plate (1), and further through the outside of the seat plate (1), and again fix the tip of the ring-shaped member (6) on the lower part of the protruding portion (4). I can do it.

In this case, as shown in FIG. 4, the hook (5) penetrates between the through hole (50) in the center and the groove (52) formed on the outside. It can be formed in a state where a narrow gap (54) to be connected is formed, or as a simple through hole (50) as shown in FIG. In the embodiment shown in FIG. 4, the ring-shaped member (6) is hung on one side of the notch (52) and forcibly pulled downward toward the through hole (50) to open a narrow gap (54). As a form in which the ring-shaped member (6) can be forcibly inserted so as to reach the through hole (50), the ring-shaped member (6) can be directly connected in a circular shape without partially cutting the ring-shaped member (6). Here, in the example shown in FIG. 4, once the ring-shaped member (6) is inserted into the through hole (50), due to the structural characteristics of the narrow gap (54), unless the ring-shaped member (6) is cut, It is difficult to separate or separate. Further, in the embodiment shown in FIG. 5, the ring-shaped member (6) cannot be inserted directly into the through-hole (50) in the form of a ring, so that a rubber-string-like form is once inserted into the through-hole (50). The front parts on both sides are connected to each other to form a ring-shaped ring member (6).

The above-mentioned protrusion (4) of the coupling (3) is manufactured as an injection-molded product of a resin material. If necessary, as shown in FIG. An auxiliary member (7) such as a permanent magnet or an iron piece is built in the inside of the part (4), while a housing part (8) is formed on one side of the seat plate (1) as shown in FIG. When the coupling member (3) is separated by attaching an easily adhered corresponding member (9) such as an iron piece or a permanent magnet corresponding to the auxiliary member (7) to the inner side of the part (8), It is easy to store and prevents loss.

[0010] The cushion sheet mounting structure of the folding table with the folding chair thus formed is used in the following manner. First, when connecting the cushion sheet (2) to the upper part of the seat plate (1), the through hole (10) and the connecting hole (20) of the cushion sheet (2) are aligned at the upper part of the seat plate (1). Place the cushion seat (2) with the, and insert the ring-shaped member (6) of the coupling (3) through the coupling hole (20) and the through hole (10), and from the bottom of the seat plate (1). The ring-shaped member (6) is grasped and pulled, and the front end thereof is again hung on the protruding portion (4) through the outer surface of the seat plate (1) to be fixed and joined. At this time, the protrusion (4) of the coupling (3) is hooked on the upper part of the coupling hole (20), so that the upper cushion seat (2) and the lower seat plate (1) are securely fixed and coupled. It has become.

On the contrary, when the cushion sheet (2) is to be removed from the seat plate (1), the ring-shaped member ( 6) If the tip of the ring is removed from the protruding part (4), it will be free from the bottom of the seat plate (1) while contracting due to the elastic force of the ring-shaped member (6), and will be connected as it is. When the protrusion (4) of (3) is grasped and pulled upward, the ring-shaped member (6) is easily removed through the through hole (10) and the coupling hole (20). As a result, the cushion sheet (2) can be easily separated from the seat plate (1).

[0012] The coupling (3) thus removed may be lost if left as it is. Therefore, the coupling (3) is stored inside the storage portion (8). By attaching it, it can be stored in a state where it will not be lost inside the storage section (8). In the above-described example, the ring-shaped member (6) is formed in a ring shape with rubber or the like, but is not limited to this, and can be formed of a flexible material such as a string. Of course.
