Description

The present invention relates to a reclining chair or sofa on which a person can sit relaxed, and the inclination and position of the seat and backrest can be easily changed according to the size and preference of the person sitting. In addition, the present invention relates to a chair or a sofa that can exhibit comfort due to the cradle effect because the seating surface and the backrest appropriately swing like a cradle when sitting. The chair or sofa of the present invention can be used not only as an indoor living room, but also as a chair or sofa installed outdoors such as a veranda, a park, a plaza, and a bus stop.

In recent years, it has become increasingly important for people to experience comfort. Conventionally, chairs or sofas that allow people to sit in a relaxed manner are known as chairs in which the rear end of the seat is inclined slightly downward, or chairs in which the upper end of the backrest is inclined slightly backward. It has been.
In addition, a reclining chair that can freely change the inclination angle of its backrest is also known, and its typical structure is that a gear for adjusting the angle of the backrest is incorporated in the connecting part between the seat surface and the backrest, Folding chair with double structure at all times by operating the lever provided at the end and changing the angle of the backrest while releasing the gear to mesh, and the seat and backrest by connecting devices such as hinges When used as a reclining chair, a method of using them as a reclining chair by unfolding them is known.
However, the above-described conventional reclining chair has a problem that it is difficult for a powerless child or woman to operate because the inclination of the seat surface and the backrest is changed by a mechanical gear operation or a large operation work. In addition, considering the conditions that people can relax ergonomically, the depth of the seating surface and the inclination of the seating surface and the backrest where people can relax are different depending on the size and preference of each person. It is required to finely adjust the seat surface tilt angle and backrest tilt angle that can increase relaxation according to the purpose of use such as reading and napping, depending on the size of the seat ing.

It is also becoming more and more important for people to experience fluctuations in a modern society where there are many solid artificial structures. For example, swings swaying in the wind, sun leaking through trees, light reflecting off a puddle of water, light leaking from curtains swaying in the wind, and so on, make people feel comfortable. For this reason, park benches under trees swaying in the wind have the power to unconsciously attract and retain people.
As swinging chairs, there are known rocking chairs, infant cradle and infant chair with automatic swing mechanism, etc., but the movements of rocking chairs are delicate movements such as “fluctuation”. is not. In addition, there are few actual examples of chairs and sofas that are installed indoors and outdoors for ordinary adults and that can be normally seated, other than rocking chairs.

In particular, in (i) which is one of the embodiments of the present invention, when the mounting support position of the seating surface or the backrest is slid back and forth along the wire member, the shape of the wire member changes due to the load. As (4), it is preferable to use a rope-shaped material made of a material whose shape can be changed.
Furthermore, as one of the preferred embodiments of the present invention, it may be mentioned that at least a part of the wire member (4) is composed of an elastic body such as a so-called spring or rubber that slightly expands and contracts in the longitudinal direction. When an elastic body is used in this way, a slight fluctuation is added when sitting on a chair, so that comfort is produced. Moreover, if the part comprised with an elastic body is chosen among wire members (4) and only the wire member which supports a seat surface rear end is made into an elastic body, for example, the elastic force will be felt only on the back side of the seat surface. Subtle adjustment of goodness becomes possible.
One end or both ends of the wire member (4) of the present invention are fixedly or movably attached to and supported by the support leg (3), and are members for hanging and supporting the seating surface and the backrest. Requires at least one set (two in total on the left and right) and has the following feature (i) or (ii).
(I) A set of wire members is formed by stretching two wire members on the left and right sides of the support leg in parallel or in parallel, in the form of spanning the front and the rear, and between the front and rear of the support leg. Composed. Specifically, one end of the wire member is attached to the front of the right support leg, the other end of the wire member is attached to the rear of the right support leg, and the approximate center of the wire member that is not the end is slightly hung The wire member of the length is used. The seat surface and the backrest are suspended and supported at a substantially central portion of the wire member.
Preferably, the seat surface and the backrest are positioned between the pair of wire members, and the seat surface and the backrest slide back and forth independently or connected along the wire members. Thus, the mounting surface is characterized in that the angle of the seating surface and the backrest and the positional relationship with each other can be adjusted.
As an aspect of (ii), the seating surface (1) and / or the backrest (2) is suspended and supported by one or more sets of the wire members (4) suspended from the left and right sides of the support legs. Has been. (See FIG. 14). Specifically, one end portion of the wire member is fixedly or movably attached to and supported by the right support leg, and the other end portion of the wire member is fixed to the rear end portion of the seating surface.
Specifically, as a structure for supporting the seating surface and the backrest by suspending them with a wire member, for example, Embodiment 1 as shown in FIGS. 1 to 6 (when supporting with one set of wires), FIG. 7 to FIG. Embodiment 2 as shown in Fig. 12 (when two seats and an auxiliary wire are used to support the seat and back), Embodiment 3 as shown in Fig. 13 (the seat and back are integrated, The rear end of the seating surface is supported by a wire member), Embodiment 4 as shown in FIG. 14 (the rear end of the seating surface (1) is the mode of (ii), that is, a wire having one end attached to the support leg. Since there is a case where it is supported by hanging by a member), it will be separately described below.

(Description of Embodiment 1)
The chair of Embodiment 1 shown in FIGS. 1 to 6 is a view showing a mode in which the seat surface and the backrest are supported by a set of wire members (4a) and (4b).
For example, one end of the right wire member (4a) is fixed or locked to a fixed upper right frame member (3i) positioned in front of the support leg (3), and the other end is behind the support leg (3). It is fixed or locked to the right rear leg (3c) located at the position. Fixing or locking may be performed on other support legs.
The wire member (4a) is a rod-like protrusion provided on the front and rear sides of the seat surface (1) in a bar-like shape in the lateral direction, and below and above the backrest (2). The seat surface and the backrest are suspended and supported by passing through the communication holes provided in the protrusions (2e) and (2f), respectively. The suspended attachment position can slide back and forth along the wire member, and can be fixed at an arbitrary position.
In order to provide both the sliding and fixing functions, for example, a stopper or the like can be used. However, as a preferred aspect of the present invention, when the load on the wire is reduced, the slide moves and the wire is applied. When the load increases, the structure to be fixed includes devising the shape of the communication hole, and using the frictional force between the hole and the wire member to fix and release it. As an example of the shape of the communication hole, various other devised hole shapes such as adopting a letter-shaped shape can be adopted. In addition, it is possible to adopt a device such as winding the wire member through the communication hole once by half a circle around the rod-shaped protrusion, and using such a hole shape and method of passing, Simple and delicate position adjustment can be performed.
In this embodiment 1, it is preferable to use a wire member made of a material such as a string-like rope that can be deformed and generates a frictional locking force due to unevenness on the surface as the wire member.
In this way, the mounting position of the seating surface and the backrest can be moved to any fixed position along the wire member, so it is possible to adjust the position of the seating surface and the backrest before and after and a delicate tilt angle. It becomes. Furthermore, in the case of a configuration in which the seating surface and the backrest are independently separated, it is possible to adjust the distance between each other.
In addition, since the seating surface and the backrest are basically suspended integrally by a pair of wire members, the so-called “fluctuation” can be more effectively experienced as compared to the example of Embodiment 2 described later. It has the merit that can be.

(Description of Embodiment 2)
Next, Embodiment 2 of the present invention shown in FIGS. 7 to 12 will be described.
The chair of embodiment 2 basically uses two sets of wire members (4a) (4b) and (4c) (4d), one (4a) (4b) supports the seat surface (1), and the other (4c) and (4d) are examples in which the backrest (2) is supported. More preferably, the seat member supporting wire members (4a) and (4b) are supported by suspending and supporting only the rear end portion of the seat surface so that the front end portion of the seat surface is stretched between the front legs of the chair. The support member supported by the auxiliary wire (7) and the wire members (4c) and (4d) for supporting the backrest are supported by hanging only the lower end portion of the backrest so as to be slidable, and the upper end portion of the backrest is supported by the chair. There is a chair supported by an auxiliary wire stretched between the rear legs, but this auxiliary wire can be replaced with an auxiliary support member attached between the front legs and a rolling bearing attached to the auxiliary support member. is there.

(Support for rear end of seating surface)
As a specific method of supporting the rear end portion of the seating surface, each of the right support leg and the left support leg has a predetermined height from the ground of the right support leg, for example, on the right side. A fixed locking portion (5) for fixing or locking the both end portions of the right side seating surface support wire member (4a) is provided at two locations, the front and the rear. The height of the fixed locking portion may be different from front to back. In the present invention, the term “locking” refers to locking in a state where fixing and releasing are easy.
The wire member (4) is a member whose length is slightly longer than the distance between the fixed locking portions, and its substantially central portion hangs downward from the height of the fixed locking portion, Fixed or locked.
Further, the rear right end (1c) of the seating surface (1) of the present invention is suspended and supported by the substantially central portion of the right seating surface supporting wire member (4a). And since it is suspended and supported at a position where the height of the rear end portion of the seat surface is slightly lower than the height of the front end portion of the seat surface, which will be described later, the seat surface is slightly lower rearward It is so inclined.
As a specific structure for suspending and supporting the rear right end portion (1c) of the seat surface by the right seat surface support wire member (4a), for example, a rod shape that is fixed to the rear of the seat surface and protrudes in a bar shape. This can be done by passing the right side seating surface support wire member (4a) through a hole (6a) provided in the lateral direction at the end of the protrusion (1e). The suspending position can be slid to any position along the wire member, and the hole (6a) and the wire can be changed by devising the shape of the hole (6a) or by devising how to wire the wire member. Using a frictional force with the member (4a), it can be movably fixed at an arbitrary position. Any other movable fixing method can be adopted.
Also in this embodiment 2, it is preferable to use a wire member made of a material such as a cord-like rope that can be deformed and generates a frictional locking force due to surface irregularities.
Thus, since it can be moved to an arbitrary fixed position along the wire member, adjustment of the inclination angle of the seat surface (1) and adjustment of the depth of the seat surface by moving the seat surface (1) back and forth. Is possible.
That is, when the fixed position of the rear end portion of the seating surface is moved forward, as will be described later, the height of the auxiliary support member with which the front end portion abuts and the height of the rear end portion are not substantially changed. Since it shrinks, the inclination of the seating surface increases and the depth also increases. On the other hand, when the fixed position is moved backward, the inclination of the seating surface is reduced and the depth is shortened.

(Support for front end of seat)
On the other hand, as shown in FIG. 7 and the like, the front end portion (1ab) of the seat surface (1) is supported on the auxiliary wire (7) stretched between the left and right front legs in front of the support leg. A mode of placing and supporting is mentioned.
When the auxiliary wire member (7) is installed such that the front end (1ab) of the seating surface (1) is located slightly above the rear end (1cd), the seating surface is slightly later. Inclination is preferable because a relaxed feeling can be obtained when sitting.
The front end (1ab) of the seating surface (1) is in a state of being placed on the auxiliary wire member (7), and the front end and the auxiliary are interlocked with the sliding movement of the rear end (1cd) before and after. The position where the wire member (7) contacts slides back and forth.
At this time, in order to prevent the seating surface from falling if the seating surface (1) comes too far forward, in order to maintain contact while sliding the auxiliary wire and the seating surface on the back side portion of the seating surface. It is preferable to attach a member (such as a kind of partial cover).
As a more preferable mode, in order to counter the force in the inward direction generated by the tension of the auxiliary wire (7) stretched between the front legs, as shown in FIG. Attach it at an angle in the direction of overturning (i.e., attach it so that it is not standing upright on the ground but tilted upward), and attach the end of the auxiliary wire to the lower part of the front leg (specifically, fix between the front legs, It is preferable that the structure be extended and attached to the fixed front frame member (3e)) because the strength and shape stability of the entire chair by the force related to the auxiliary wire (7) can be enhanced.
Further, this auxiliary wire can be replaced by an auxiliary support leg attached between the front legs or a rolling bearing attached thereto.

(Support for backrest)
As a preferable support mode of the backrest (2) of Embodiment 2, only the lower end portion of the backrest is supported by the rear support wire members (4c) and (4d) so as to be slidable, and the upper end portion of the backrest is behind the chair. There is a mode supported by an auxiliary wire stretched between legs, but this auxiliary wire, like the seating surface, can be replaced with a supporting leg attached between the rear legs and a rolling bearing attached thereto. is there.
In particular, it is preferable to support the backrest so that the lower end portions (2c) and (2d) of the backrest are positioned above the rear end portions (1c) and (1d) of the seating surface with a slight gap.
Specifically, in each of the right support leg and the left support leg, for example, on the right side, a predetermined height from the ground of the right support leg (the fixed locking part supporting the seat surface). Fixed locking portions (5c, 5d) for fixing or locking the both end portions of the right rear surface supporting wire member (4c) are provided at two positions, front and rear, above the position.
The right rear support wire member (4c) is a member whose length is slightly longer than the distance between the front fixed locking part (5c) and the rear fixed locking part (5d), and is substantially at the center. The part is below the height of the fixed locking part, but is fixed or locked so as to hang down in a range above the hanging position of the rear end of the seating surface.
Further, the lower right end (2c) of the backrest (2) of the present invention is suspended and supported at the substantially central portion of the right back support wire member (4c).
The specific structure for suspending and supporting the lower right end (2c) of the backrest by the right seat surface support wire member (4c) can be the same as the structure of the seat surface described above. The hanging position of the backrest can also be moved and fixed at an arbitrary position along the wire member.
In addition, because of the suspension support, the lower end (2cd) is installed so that the lower end (2cd) is inclined slightly forward rather than the upper end (2ab) of the backrest (2), so that a relaxed feeling can be obtained when sitting. . In addition, since the angle of the backrest changes by moving the position of the lower end of the backrest back and forth without changing the position of the upper end of the backrest, the user can change the angle according to the purpose of use such as reading or napping. Can be adjusted.
The upper part of the backrest (2) is supported by leaning on an auxiliary wire member (7b) that is fixed and locked at both ends of the support leg constituting the rear leg at two left and right positions of a predetermined height. It is an aspect to do. Similar to the seating surface, this auxiliary wire can be replaced by a supporting leg attached between the rear legs or a rolling bearing attached thereto.
Note that the support position of the upper end portion is not necessarily the end portion, and any position can be selected as long as it is an upper portion that is half or more of the backrest.
In any aspect, since the position of the lower end (2cd) and the upper position of the backrest (2) can be moved slightly back and forth, the inclination angle and position of the backrest can be finely adjusted. .
As described above, in the example of the second embodiment, it is possible to change the inclination angle of the seating surface (1) and the inclination angle of the backrest (2) to be larger than those in the example of the first embodiment. Since the front and back position fluctuation range of the surface and the backrest is wide, there is an advantage that the depth of the seat surface can be adjusted according to the body shape of the person sitting.

(Description of Embodiment 3)
Next, Embodiment 3 of the present invention shown in FIG. 13 will be described.
The chair of embodiment 3 is basically an example in which the chair of embodiment 2 is simply configured, and since the seat surface (1) and the backrest (2) are connected and integrated, the angle of the seat surface and the backrest is It is fixed.
This is an example in which the rear end portion of the seating surface is supported basically using a set of wire members (4a) and (4b). Preferably, the wire member (4a) for supporting the seating surface supports only the rear end portion of the seating surface so as to be slidable, while the front end portion of the seating surface is stretched between the front legs of the chair. It is an aspect supported by the auxiliary support member (7). In addition, as this auxiliary | assistant support member, a wire-shaped thing may be used, and the member of the material similar to a support leg body, and the rolling support attached to it may be used.
Moreover, at least a part of the wire member (4) and the auxiliary support member (7) is provided with an elastic body such as a rubber or a spring which has strength and weather resistance and is bent or shakes slightly when a load is applied. It is also possible to configure. For example, FIG. 13 shows an example in which a part (4e) of the rear portion of the wire member (4) is made of an elastic body, and the seat surface rear slightly sinks when seated, thereby obtaining a more sense of fluctuation. Can relax.
On the other hand, instead of or in addition to configuring the wire member itself with an elastic body, an elastic structure for receiving the wire member with some elasticity when a load is applied to the wire member, even when the wire member is attached to the support leg May be installed. For example, as shown in FIG. 16 to be described later, a mode in which a spring is wound around the lower part of the leg and a ring-shaped attachment part of the wire member is provided on the upper part of the spring can be adopted.

(Description of Embodiment 4)
Embodiment 4 shown in FIG. 14 is a chair corresponding to the embodiment (ii) of the present invention, unlike Embodiments 1 to 3. In addition, although the example which connected and integrated the seat surface and the backrest is shown in this figure, you may comprise and support each independently.
In the drawing, one end of the wire member (4) is attached to the left and right support legs, specifically to the substantially central portion of the fixed frame member, so as to be slidable back and forth. The other end suspends and supports the rear end of the seating surface (1). Note that both end portions may be attached to the fixed frame member, and the rear end portion of the seating surface may be suspended and supported at a substantially central portion. On the other hand, the front end portion of the seat surface is supported by an auxiliary support member (7) stretched between the front legs of the chair.
Specifically, as a configuration in which the attachment part of the wire member is slidable in the front-rear direction along the fixed frame member, for example, a configuration in which the end of the wire member is ring-shaped and the fixed frame member is passed through the ring, Any configuration such as an engagement configuration found on curtain rails or the like can be employed.
According to this configuration, if the mounting portion of the wire member is slid rearward along the fixed frame member, the inclination of the seating surface and the backrest is reduced, and if the sliding is performed forward, the inclination is increased. The inclination can be easily changed.
However, since the aspect of this Embodiment 4 is suspended with one wire member compared with the aspect of Embodiments 1-3, it is hard to feel a fluctuation. Therefore, you may comprise a wire member with an elastic body. On the other hand, in this aspect, since the wire member itself does not need to be variable, it may be made of a material that emphasizes strength and the like.

(Description of Embodiment 5)
Embodiment 5 shown in FIG. 15 and FIG. 16 is a chair of an aspect corresponding to a further development of Embodiment 3 and Embodiment 4.
FIG. 15 shows a mode in which the inclination of the seat and the backrest when used for reading or watching TV is reduced (referred to as “upright mode” for convenience), and FIG. 16 increases the inclination when used for napping. This mode (referred to as “tilt mode” for convenience) can not only adjust the tilt angle of the subtle seating surface (backrest) within the vertical mode and tilt mode, but also between the vertical mode and the tilt mode. It has the merit that the inclination angle of the seating surface (backrest) can be changed with a simple operation.
In the fifth embodiment, the front end portion (1ab) of the seating surface is supported by being placed on the auxiliary support member (7) located in front of the support leg as in the second to fourth embodiments. 15 and the like, the left and right front end portions of the seating surface may be suspended and supported by wire members having one end fixed or locked to the support leg.
And the rear-end part (1cd) of the seat surface is suspended and supported by the wire member (4).
One end (4f) of the wire member (4) that supports the suspension of the rear end of the seating surface is fixedly or movably attached to the front of the support leg, and the other end (4g) is A support leg is movably attached.
The wire member (4g) on the other end side is mounted and supported so as to be slidable along the supporting leg, and the movable mounting portion is positioned on the fixed upper right frame member (3i), and the fixed upper right frame member ( 3i) in the upright mode (FIG. 15) that can slide horizontally and back and forth, slide and move up and down along the right rear leg (3c), and move the fixed upper right frame member (3i) When fixed or locked at a position lower than the height, it is possible to easily change to an inclination mode (FIG. 16) in which the inclination of the seating surface and the backrest is further increased. In the figure, an elastic structure (8) is installed in the attachment portion of the wire member to the right rear leg (3c) to receive the wire member with some elasticity when a load is applied. The configuration is optional, and such a configuration is preferable because the feeling of fluctuation is further increased.
Further, for example, the right rear leg (3c) constituting the support leg and the fixed upper right frame member (3i) for fixing between the right front leg and the right rear leg are connected to form a sliding movement of the movable attachment portion. It is preferable to adopt a configuration that allows smooth operation. This connecting structure may be square or an arched connecting structure as shown in FIGS. 15 and 16 is preferable. On the other hand, when using the upright mode, in order to prevent the attachment part from unintentionally sliding and changing to the tilt mode, the attachment part of the ring-shaped wire member is spontaneously provided at the rear part of the fixed upper right frame member (3i). It is preferable to provide a structure in which a stopper such as an upper protrusion is provided to prevent general movement.
The wire member (4) constituting the embodiment 5 may be a deformable material such as a string-like rope or a stainless steel chain, or a material that is not variable, such as a stainless steel bar or wood. It may be.
The wire member may be formed by one, or may be formed by two wires: a wire member located in front of the attachment site with the rear end of the seat surface and a wire member located behind.
When the wire member is made of a single deformable material, the attachment portion at the rear end portion of the seating surface may be slid along the wire member in the tilt mode. In the upright mode, by slightly moving the movable attachment part back and forth, the slight inclination can be adjusted as in the fourth embodiment of FIG.

In addition, although not shown in the drawings, the length of the auxiliary wire (7) that supports the front end of the seat surface in a suspended manner is adjusted instead of or together with the rear end of the seat surface being moved back and forth. By providing a mechanism or a mechanism for adjusting the height of the auxiliary support member (7 '), the angle of the seating surface can be adjusted by changing the vertical position of the front end portion of the seating surface. The chair of the further aspect which can be made can be made.
Similarly, instead of moving the lower end of the backrest back and forth, or together, the position of the upper end of the backrest can be changed back and forth by changing the position of the auxiliary wire or auxiliary support member in the front-rear direction. You can also adjust the angle.

As described above, the chair of the present invention has at least one set of wire members (4) in which the seating surface and / or the back surface is fixedly or movably attached to and supported by the support legs in the mode (i) or (ii). ), It is characterized by being supported by hanging, and it is possible to experience the comfort of sitting by bouncing or the like when sitting.
More preferably, it can be slid to an arbitrary fixed position along one or more sets of wire members stretched in parallel or in parallel with the front and rear of the support leg, so that the inclination angle of the seat surface (1) can be adjusted, The seat surface (1) can be easily adjusted in the front-rear position, and the reclining shape of the chair can be finely adjusted according to the size and preference of the seated person, and subtle fluctuations can be experienced. it can.
