Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a flexible chair that can be used in various ways by freely rearranging parts of the chair.

``Problems to be solved by conventional techniques and ideas'' Various types of chairs that can be assembled and chairs that can be folded have been provided in the past.

However, although various improvements have been made to the assembly structure and folding structure of each of these conventional chairs depending on the purpose of each chair, each of these structures only satisfies assembly or folding. For example, a chair that also has a structure that allows parts of the chair to be freely rearranged and used in various ways has not yet been provided.

In particular, in the case of a chair, no matter what the structure, the seat and legs are naturally necessary components for the construction, so depending on the usage, they are never necessary or unnecessary, but the back The stand may or may not be necessary depending on the manner of use. However, in the case of conventional chairs, the presence or absence of a backrest is determined in advance, so they cannot be rearranged freely each time they are used. It had the disadvantage and inconvenience that it could only be used in the

``Means for Solving the Problems'' Therefore, the present invention was developed to effectively solve the problems of conventional chairs. Assuming that the chair is composed of: a pair of crosspieces each having a connecting hole at each end, and a seat plate laid on the top surface excluding a part of the other end of the crosspieces, The legs consist of a pair of inner legs and a pair of outer legs, whose upper and lower parts are connected by connecting reinforcing members, respectively, and each of the inner and outer legs is pivoted in an X-shape at approximately the center. At the same time, a connecting hole is formed in the upper end of each leg member, and each connecting hole of the outer leg member is pivotally connected to the connecting hole on one end side of the above-mentioned crosspiece via a connecting means, and each of the inner leg members is The connecting hole is configured to be pivotally connected to the connecting hole on the other end side of the crosspiece via a connecting means by sandwiching the side members of the backrest portion (to be described later), and the backrest portion is connected to a pair of side members and one side member of the both side members. It consists of a back plate constructed at the upper end of the side surface and a stopper plate installed horizontally at the lower part of the other side surface, and connecting holes are formed at both ends of the pair of side members, and each connecting hole is individually connected to the A configuration is adopted in which the side member can be rearranged and connected to the crosspiece and the inner leg through a connecting means by matching the connecting hole on the other end of the crosspiece to the connection hole of the inner leg.

"Operation" Accordingly, in the present invention, connecting holes bored at both ends of the side members constituting the backrest are selected, and the selected connecting holes are connected to the inner legs of the seat and the legs. By matching the connecting holes in the material and freely connecting the three parts, it is possible to rearrange the chair into at least a chair with a backrest part and a chair without a backrest part, so the chair itself can be used. This will help expand the number of companies.

``Embodiment'' Hereinafter, the present invention will be described in detail based on an embodiment illustrating the present invention.As shown in FIG. It is something that will be done.

Specifically, the first seating portion includes a pair of crosspieces 1, each having connecting holes 1a and 1b formed at appropriate positions at both ends.

The crosspiece 1 and the outer leg members 5 are connected to each other by matching from the inside and pivoting with bolts and nuts 7, and the connecting holes 4a, 4a of the inner leg members 4, 4 are connected to the backrest portion, which will be described later. By sandwiching the side members of the cross members 1, 1, and aligning them with the connecting holes 1b on the other end side of the cross members 1 from the inside, and pivotally connecting them with bolts and nuts 7, the cross members 1 and the inner leg members 4 are connected to each other. Eggplant.

Therefore, the width W ₁ between the outer surfaces of the pair of outer leg members 5, 5 is equal to the width W 1 between the inner surfaces of the two crosspieces 1, 1, but the width W 1 between the outer surfaces of the pair of inner leg members 4, 4 The width dimension _W2 is shorter than W by twice the width of the outer leg member 5 itself in order to allow the interposition of the side members of the backrest between the outer surface of the outer leg member 1 and the inner surface of the outer leg member 1. Set it as follows.

Furthermore, the third backrest portion includes a pair of side members 8, 8.
The pair of side members 8, 8 consists of a back plate 9 horizontally installed on the upper edge of one side of the side members 8, and a stopper plate 10 horizontally installed on the lower part of the other side. 8
Connecting holes 8a and 8b are bored at appropriate positions at both ends of the frame, one of the connecting holes 8a and 8b at both ends is selected, and the selected connecting hole is connected to the connecting hole 1b on the other end of the crosspiece 1 and the inner leg member. By matching the connecting holes 4a of 4 and pivotally connecting the three together with bolts and nuts 7 serving as connecting means, each side member 8 can be freely rearranged and connected to the crosspiece 1 and the inner leg member 4. Nasu.

Therefore, the width dimension between the outer surfaces of the pair of side members 8, 8
W ₃ is equal to the width W between the inner surfaces of the two crosspieces 1, 1, and conversely, the width W ₄ between the inner surfaces of the side members 8, 8 is
It is set to be equal to the width dimension W ₂ between the outer surfaces of the inner leg members 4, 4.

Next, a case will be described in which, in a chair having such a configuration, the backrest portion can be freely rearranged to obtain various usage modes.

First, when converting to a chair with a backrest, as shown in FIGS. 2A and 2B, one end connecting hole 1a of the crosspieces 1 and 1 that constitute the seating part, and the outer leg members 5 and 5 that constitute the legs, The connecting holes 5a of 5 are pivotally connected with bolts and nuts 7 to connect the outer leg members 5 and the crosspieces 1, while the side members 8, 8 constituting the backrest are
The lower end of the crosspieces 1, 1 and the inner leg members 4 are interposed between the connecting holes 1b on the other end side of the crosspieces 1, 1 and the side members 8, 8.
When the lower end connecting hole 8a of the inner leg member 4 and the connecting hole 4a of the inner leg member 4 are pivotally connected with bolts and nuts 7, the side members 8, 8 connect the stopper plate 10 horizontally installed at the lower part of the other side of the side members 8, 8 to each cross member. The seat plate 2 of 1 is connected to the upper surface of the exposed part 3 that is not laid down and is prevented from rotating outward, so that the backrest part can be used as a normal backrest due to this connection. will be defined.

Therefore, in such a state, it can be used as a normal chair with a backrest. Although not specifically shown, if the abutment surface of the stopper plate 10 against the exposed portion 3 is an inclined surface having an arbitrary angle, it is also possible to connect the backrest portion in an inclined state according to the inclination angle. Become.

Next, when changing from this state to a chair without a backrest, as shown in FIGS. A state is obtained in which the side members 8, 8 are placed on the exposed portion 3 on the other end side, and the respective side members 8, 8 are housed in a state parallel to the inside of the crosspieces 1, 1, and the upper ends of each side member 8, 8 are connected. Hole 8
When b is similarly pivotally connected to the connecting hole 1b on the other end side of the crosspiece 1 and the connecting hole 4a of the inner leg member 4 with bolts and nuts 7, the backrest portion is securely stored and connected to the back side of the seating portion, and is completely connected. It will be hidden. In addition, in this state, the back plate 9 constituting the backrest part
A crosspiece 1 that also serves as a seat plate and constitutes a seating section.
1, the seat board is laid over the entire area.

Therefore, in such a state, it is of course possible to use it as a normal chair without a backrest, but it can also be used as a table or a stand or shelf for placing flower pots, etc. Can be expanded.

Furthermore, although the above embodiment is configured as a chair for one person, the length dimensions of each part of the seat, legs, and backrest were lengthened based on the structure of the embodiment. Once set, it can be used as a chaise lounge for multiple people.

In other words, when the chaise longue has a backrest, it can be used as a bench as shown in Figure 4, and when it is replaced with a chaise longue without a backrest, it can be used as a bench as shown in Figure 5. It becomes possible to use In the latter case, as mentioned above, it can be used not only as an edge stand but also as a table, a stand for placing flower pots, etc., or a shelf.
