Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wooden swing chair having good cushioning properties.

[0002]

[Prior art]

 Conventionally, a wooden chair is obtained by cutting a plurality of pieces of wood into a predetermined shape, combining the cut pieces with nails or the like, and keeping the angle of the backrest with respect to the seat surface constant.

Also, a sofa or the like has a cushion attached around a wooden frame, and the elasticity of the cushion gives elasticity to the backrest, but the angle is determined by the frame. The angle is constant.

On the other hand, many steel chairs are used for business. Steel chairs are sturdier than wooden ones, but because of their weight, they are mainly fitted with a plate-shaped seat and backrest on a pipe frame.

In recent years, the angle of a steel chair can be adjusted by using a spring or the like to bias a member that supports the backrest toward the front, and press the backrest rearward with the back. Structures are increasing.

[0006]

[Problems to be solved by the invention]

 However, the conventional steel chair has a structure in which the base of the member supporting the backrest is attached to the lower part of the plate-shaped seating surface and rotates around this portion. There is a problem that the angle of the backrest changes suddenly and is not stable.

[0007] Further, since the steel chair is designed for office use, there is also a problem that it cannot be harmonized with the indoor space when used for home use.

Therefore, an object of the present invention is to provide a wooden swing chair that can be used at home by stably changing the angle of the backrest.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the wooden swing chair of the present invention has a built-in cushion inside, a seat having a notch formed on the rear side, and a lower end pivotable to the rear lower end of the seat. And a wooden support member having an intermediate portion disposed so as to be able to fit into the notch, an upper portion protruding upward, and a wooden support member provided at a lower end portion of the support member to bias the upper portion forward. A swing mechanism provided with a biasing means, and a back plate member provided above the support member and capable of swinging back and forth are provided.

The urging means may urge the upper portion to the front side by, for example, pressing a portion below the center of rotation of the support member to the rear side or pulling an upper portion from the center of rotation to the rear side. it can. Since the strut member fits into the notch, the force applied to the strut member can be received by the seat. Furthermore, since the support member is made of wood, it is in harmony with other wooden furniture.

Further, the thickness of the seat portion can be set to 20 cm or more and 45 cm or less. The reason for this setting is that when the length is smaller than 20 cm, the length of the support member is shortened and the turning radius of the back plate member is small. Is too high and it becomes difficult to sit. When the length of the strut member is set to 20 cm or more, the length of the strut member increases, and the turning radius of the back plate member increases. In addition, since the portion that fits into the notch of the support member increases, the support member can be reliably protected.

In the swing mechanism, a center axis provided at a lower end portion of the support member and serving as a rotation center is disposed between the support member and the seat below the center axis. It is also possible to provide a spring member. As the spring member, for example, a leaf spring, a deformed member such as a knob-shaped or a barrel-shaped or a cylindrical coil spring can be used.

[0013] With this configuration, the structure of the swing mechanism can be simplified, and the number of components can be reduced to facilitate manufacture. In addition, since the spring member is disposed below the center axis, the spring member can be built in the seat, and the swing mechanism can be made compact.

It is also possible to provide a plurality of free wheels under the seat. With such a configuration, even when the weight of the seat portion increases, the movement can be easily performed, and the usability at the time of use or storage is good.

Further, it is possible to provide a plurality of sets of the support member, the swing mechanism, and the back plate member in one seat. With this configuration, a plurality of persons can be seated at the same time, and each person can tilt each back plate member at a different angle.

It is also possible to provide a fixed wheel on the lower front side of the seat and to provide a fixed leg on the lower rear side. The fixed wheel rolls by lifting the rear side of the wooden swing chair, so that it can be easily moved. In addition, since a fixed leg is provided, it can be used in a normally stabilized state.
