The present invention relates to a seating seat in which a seat portion is positioned on the floor surface without forming a separate leg in a restaurant or home, and more particularly, a seating seat which can maintain a stable seating state even if the floor surface is not flat. It is about.

As shown in Fig. 1, the seat 10, generally called a liver chair or a cushion chair, is made of a seat 11 with a cushion and a back portion 12 that can lean on the back, and the legs are integrated. It has an excluded structure. Therefore, the user can rest comfortably by leaning against the back while sitting comfortably on the floor instead of the cushion, which is widely used in restaurants and homes.

The seat part 11 and the back part 12 are manufactured integrally by using aggregated wood or synthetic resin, which is generally called a high-pack, lightweight and high elasticity, and is formed to be bent along a user's body profile to increase seating comfort. And the seat portion 11 is manufactured in a planar state in relation to being placed on the floor.

However, in the conventional seated seat 10 as described above, when the user leans against the backrest forcibly, the backrest part 12 exceeds the elastic limit and the crack occurs around the boundary with the seat part 11 and the backrest is severe. When the part 12 is broken, a safety accident occurs.

In addition, as shown in Figure 2, when the floor is not flat, the seating seat 10 is not able to maintain a horizontal state, so the accident is overturned frequently.

The present invention has been made in consideration of the above-described conventional problems, and the user is not rested even when the user leans against the backrest, and the backrest does not break, and even if the floor is not flat, a seating seat which can always maintain a stable seating state is provided. There is this.

In order to achieve the above object, the present invention is a seat; A backrest portion which is elastically deformed and the backrest angle is changed when an external force is applied; A seat frame supporting the lower part of the seat part; A backrest frame attached to or extended from the rear of the seat frame to contact the back of the user's back or backrest part when the backrest part is elastically deformed by a predetermined angle or more so that the backrest part is elastically deformed by a certain angle or more; And a plurality of flow support members installed on the bottom of the seat frame or the backrest frame and supported on the bottom surface, and flowing according to the state of the bottom surface to maintain a close contact with the bottom surface.

In addition, a plurality of insertion holes may be formed at the bottom of the seat frame, and a ball-shaped joint part may be formed at the upper portion of the flow support member to be inserted into the insertion hole in a state capable of flow.

In addition, a plurality of insertion holes are formed at the bottom of the seat frame, a ball-shaped joint portion is formed at the upper portion of the flow support member, and the insertion hole is inserted into a state in which the connection member is formed to be separated so that they can be matched from side to side. Is coupled, the joint portion of the flow support member may be assembled to enable the flow in the lower inner side of the connecting member in a state in which the connecting member is separated left and right.

The features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments based on the accompanying drawings. Prior to this, terms or words used in the present specification and claims are defined in the technical spirit of the present invention based on the principle that the inventor can appropriately define the concept of the term in order to best describe his or her own design. It must be interpreted to mean meanings and concepts.

As shown in FIGS. 3 to 5, the subject innovation of the present invention includes a seat unit 110, a backrest unit 120, a seat frame 130 supporting the seat unit 110, and the backrest unit 120. When the elastic deformation more than a certain angle back contact with the back of the user's back or back portion 120 by the back frame 120 to limit the elastic deformation over a certain angle and the seat frame 110, the seat frame 110 Is installed on the bottom of the) is composed of a plurality of flow support members 150 to maintain the close contact with the bottom surface while flowing in accordance with the state of the bottom surface.

Since the seat portion 110 and the backrest portion 120 are the same as the conventional one, detailed description thereof will be omitted.

The seat frame 130 supports the lower portion of the seat portion 110 horizontally, preferably in the form of a pipe to minimize the weight.

The seat frame 130 may be fastened to the seat part 110 with a bolt. In this case, the seat part 110 integrally forms a rib 111 at the bottom of the seat part 110 and the rib 111 It is preferable to be bolted to the seat frame 130 via a). This is because the thickness of the seat portion 110 is not only difficult to normal bolt fastening, but also the screw portion of the bolt fastened from the bottom of the seat frame 130 penetrates through the seat portion 110 of the seat portion 110 This is to prevent protruding to the seating surface.

In addition, by forming the ribs 111 it is possible to form a body profile on the seat portion 110 it is possible to maximize the seating feeling. That is, the height of the rib 111 can absorb the profile height. In addition, the bottom shape of the rib 111 is formed in the same shape as the top surface of the seat frame 130 to improve the coupling force between the rib 111 and the seat frame 130.

For example, the seat frame 130 is bent to form an "X" shape, but is not limited thereto. Of course, the seat frame 130 may be formed in various forms.

The backrest frame 140 is manufactured in the shape of a pipe such that the weight is minimized like the seat frame 130. The back frame 140 is attached to the rear of the seat frame 130 or integrally formed to be in contact with the back of the user or the back of the back 120 when the back portion 120 is elastically deformed over a predetermined angle. It is bent.

In this embodiment, as shown in Figure 6, for example, the back frame frame 140 to support the user's back, for example, in this case, the back frame 140 is the elasticity of the back portion 120 It is bent so as not to be located in the deformation region.

Therefore, the backrest part 120 is limited to elastic deformation more than a predetermined angle by the backrest frame 140, so if the user leans against the backrest, the backrest frame is before the backrest part 120 exceeds the elastic deformation limit. Since the back of the user's back or back portion 120 is supported, the back portion is no longer elastically deformed, thereby preventing the back portion 120 from being damaged. Here, the constant angle refers to the angle of the backrest in the elastic deformation state that the backrest portion 120 is set to the maximum allowed in design.

In addition, since the back frame is firmly supported by the user, the user can lean back more comfortably.

On the other hand, the insertion hole 131 is formed in the bottom of the seat frame 130 or the bottom of the back frame 140. The insertion hole 131 is fitted with a flow support member 150 supported on the bottom surface.

On the other hand, the insertion hole 131 may be made through the hole processing in the seat frame 130 or the backrest frame 140, as shown, may be an open end of the seat frame 130 and the backrest frame 140. have.

The flow support member 150 fitted into the insertion hole 131 has a horizontal surface in close contact with the bottom surface and a joint part 151 fitted into the insertion hole 131 in a state capable of flow. The horizontal surface is preferably provided with a non-slip member 152 to improve the grounding force with the bottom surface. The non-slip member 152 is a pad of rubber material having a high coefficient of friction with the bottom surface.

The joint part 151 is completely inserted into the insertion hole 131 through interference fit. Therefore, the flow support member 150 is suspended in the insertion hole 131 and flows around the joint part 151 when an external force is applied.

On the other hand, the joint portion 151 may be made of a material having self-elasticity so as to easily fit in the insertion hole 131. In addition, when the insertion hole 131 is the open end of the seat frame 130, the joint part 151 is inserted so as not to be separated from the insertion hole 131 while the joint part 151 is fitted into the insertion hole 131. The end of the ball 131 may be properly compressed.

Therefore, even if the floor on which the sheet is placed is not flat, the user is concerned with the state of the floor because each of the flow support members 150 installed at the bottom of the seat frame 130 adheres to the bottom while flowing along the floor. You can always maintain a stable seating state without At this time, the flow support member 150 is given a flow force by the vertical load generated by the self load of the seat or the weight of the user.

On the other hand, as shown in Figure 7 and 8, as another embodiment of the present invention, the flow support member 150 is able to flow in the insertion hole 131 via a separate connection member 160. It may be installed.

In this case, the connecting member 160 is separated into a left body 160a and a right body 160b to be symmetrical. The left body (160a) and the right body (160b) is formed so that the projections 164 and grooves 165 corresponding to each other are formed on the opposite surface facing each other and can be matched.

In addition, hemispherical grooves 161 are formed in the lower inner sides of the left body 160a and the right body 160b to surround the joint part 151, respectively, and on the outer circumferential surfaces of the left body 160a and the right body 160b. A protrusion 162 is formed to be in close contact with the inner circumferential surface of the insertion hole 131 to prevent the connection member 160 from being separated. The protrusion 162 is formed in the horizontal direction along the outer circumferential surface. In addition, the lower end of the left body (160a) and the right body (160b) is formed with a locking projection 163 is caught in the insertion hole 131 to prevent the connection member 160 is completely inserted into the insertion hole (131).

The connection member 160 configured as described above is matched in the state where the joint part 151 of the flow support member 150 is seated in the hemisphere groove 161 formed at the bottom thereof, and in the insertion hole 131 in the matched state. The fittings are combined. The flow support member 150 is suspended in the lower portion of the connection member 160, so when the external force is applied, the flow support member 150 may freely flow around the joint part 151.

When the flow support member 150 and the insertion hole 131 are connected using the connection member 160 as in the present embodiment, the connection work between the flow support member 150 and the insertion hole 131 is more simple. The assembly of the flow support member 150 and the insertion hole 131 can be made very stable.

Seated seat according to the present invention configured as described above is because the backrest frame restrains the backrest elastically deformed more than a certain angle, even if the user forcibly rests on the backrest, the backrest is not damaged and the life of the seat is improved as well as the user's. Since the back can be stably supported, seat comfort is also greatly improved.

In addition, the seating seat according to the present invention is able to maintain a stable seating state regardless of the state of the bottom by the flow support member installed on the bottom of the seat frame not only greatly improves seat seating feeling but also psychological according to the rollover of the seat You can expect the effect to relieve anxiety.
