Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to furniture for rest such as beds, sofas, and sofa beds.

(Prior Art) Generally, resting furniture such as the bed, sofa, or sofa bed described above is composed of a base and a portion provided on the base for a user to sit on.

Conventionally, a portion for a user to sit or lie down has been fixedly provided to the base body. As a result, the comfort during use has sometimes been lower than when that part oscillates, such as in a rocking chair.

Therefore, as shown in Utility Model Application No. 61-62726 and Japanese Patent Application No. 61-81735, the applicant proposed a rest area in which the part on which the user sits or lies is swingable relative to the base. I suggested furniture. These prior art techniques have a base body and a movable body, and the movable body is supported with respect to the base body by a wire. Therefore, the movable body can swing while bending the wire.

By the way, in the above-mentioned prior art, when the movable body is not swinging, the wire whose upper end is connected to the base body and whose lower end is connected to the movable body is provided so as to be substantially vertical. Therefore, when the movable body swings, for example, in the front-back direction while bending the wire, the upper surface of the movable body swings back and forth while changing its height in the vertical direction while remaining in a substantially horizontal state. Therefore, the upper surface of the movable body does not move in a gentle convex manner like the upper surface of the rocking chair, so the user sitting or lying on the movable body cannot move comfortably like the rocking chair. There were times when I couldn't get enough sex.

Further, the wire supporting the movable body does not elastically expand or contract due to the load applied by the movable body. Therefore, when the user sits or lies on the movable body, the movable body will not be elastically displaced in response to the user's load, providing good cushioning properties to the user. There were times when I was unable to do so.

(Problem to be solved by the invention) In this way, in conventional rest furniture, the upper surface of the movable body did not swing while drawing a gently convex curved shape like a rocking chair. Comfort like air cannot be obtained, and the movable body is not supported elastically, resulting in poor cushioning properties.

This idea was developed based on the above circumstances, and its purpose is to be able to swing the movable body so that its upper surface draws a gently convex curved shape, and to load the movable body with the load applied to the upper surface. To provide furniture for rest that can exhibit good cushioning properties.

[Structure of the device] (Means and effects for solving the problem) In order to solve the above problem, this device has a base body and a movable body, and this movable body is a bendable body whose upper end is connected to the base body. In the resting furniture connected to the lower end of the connecting member and swingably provided on the base, the connecting member is formed of a stretchable elastic material, and the upper end is inclined outwardly than the lower end. Place it in the state.

With this configuration, the movable body can be swung so that its upper surface draws a gently convex curved surface, and can also exhibit cushioning properties against loads applied to the upper surface.

(Embodiment) An embodiment of this invention will be described below with reference to FIGS. 1 to 4. 2 and 3 show a chair as a piece of rest furniture, which chair is equipped with a basic body 1. FIG. The base body 1 has a ring-shaped base member 2, and a support pipe 3 is vertically provided in the center of the base member 2. A rotating body 4 is rotatably supported by the support pipe 3. As shown in FIG. 4, this rotary body 4 has a double pipe structure consisting of an inner cylinder 5 and an outer cylinder 6 whose upper end faces are closed, and the inner cylinder 5 is rotatably attached to and external to the support pipe 3. It is fitted. A receiver 7 having a spherical upper surface is fitted onto the upper end of the support pipe 3, and the spherical surface of the receiver 7 supports the rotating body 4 so that it can rotate easily.

One ends of two front base pipes 8 and two rear base pipes 9 are fixed to the rotating body 4 at intervals of approximately 90 degrees in the circumferential direction. As shown in FIG. 3, these base pipes 8 and 9 are bent into a substantially crank shape, and one end is located above the other end.

The four base pipes 8 and 9 have seat portions 11a.
A movable body 11 having a back portion 11b and a back portion 11b is supported. That is, the movable body 11 is formed by attaching an elastic material 13 such as urethane foam to a frame 12 whose side surface is curved into a substantially L-shape, and covering the elastic material 13 with an exterior body 14 .

Armrest pipes 15 are provided on both sides of the frame 12.
is attached. This armrest pipe 15 includes a pair of armrest portions 16 bent into an approximately inverted U shape,
A pair of horizontal rod portions 17, both ends of which are continuous, are integrally formed at the lower ends of the front end side and the rear end side of these armrest portions 16. And both ends of the pair of horizontal rod portions 17,
The other ends of the four base pipes 8 and 9 are connected by connecting members 18, respectively. As shown in FIG. 1, the connecting member 18 is made of an elastic material such as rubber and formed into a columnar shape with a parallelogram side surface, and mounting plates 19 are fixed to the upper and lower end surfaces of the column. . One end of a bolt 21 is attached to each mounting plate 19 perpendicularly to the plate surface of the mounting plate 19 by means such as welding. Bolt 2 attached to the upper end of the connecting member 18
1 is inserted into a first through hole 22 formed at the other end of the base pipe 8 or 9;
A nut 23 is screwed onto the protruding end from 2.
Further, the bolt 21 attached to the lower end is inserted into a second through hole 24 bored in the end of the horizontal rod portion 17 of the armrest pipe 15 located below the other ends of the base pipes 8 and 9. This second through hole 24
Similarly, a nut 23 is screwed onto the protruding end from the holder. The center line O of the connecting member 18 is inclined outward with respect to the front-rear direction of the chair, as shown in FIG. 1 or 3. In other words, the center line O of the pair of connecting members 18 connecting the front end sides of the seat portion 11a of the movable body 11 is at an angle with respect to the vertical line such that the upper end is directed more forward (outward) than the lower end. The center line O of the pair of connecting members 18 connecting the rear end sides of the seat portions 11a is tilted at an angle α with respect to the vertical line, with the upper end facing rearward (outward) than the lower end. It is sloping.

According to the chair configured in this way, when a user (not shown) sits on the seat portion 11a of the movable body 11, leans against the back portion 11b, and applies a force in the front and back direction to the movable body 11, the movable body 11 is connected. The member 18 swings back and forth while being elastically deformed.

The four connecting members 18 that swingably support the movable body 11 on the base 1 are inclined at an angle α such that the upper ends thereof are directed outward from the lower ends. Therefore, when the movable body 11 swings forward, the lower end of the connecting member 18 on the front end side swings in the upward direction as shown by arrow a in FIG. It also swings in the upward direction as shown in . At this time, when comparing the amount by which the lower end of the connecting member 18 on the front end side and the rear end side is displaced in the vertical direction, it is found that the lower end is
The connecting member 18 on the rear end side is inclined toward the front of the
The amount by which the lower end is displaced upward is larger than that of the connecting member on the front end side which is inclined toward the rear of the base body 1. Then, within a predetermined range of amplitude, when the movable body 11 swings furthest forward, the lower end of the connecting member 19 on the front end side moves in the upward direction more than the lower end of the connecting member 19 on the rear end side. displacement becomes slightly smaller. Therefore, the upper surface of the movable body 11 draws a trajectory opposite to the locus of the lower end of each of the connecting members 19, so that as the movable body 11 swings forward, the front end side becomes the rear end. It will swing while drawing a convex curved arc that is slightly lower than the sides.

Moreover, when the movable body 11 swings backward,
As the movable body 11 swings backward, contrary to forward swinging, it swings along a convex curved trajectory in which the rear end side slightly descends and the front end side rises.

Therefore, the movable body 11 swings back and forth while its upper surface traces a gentle convex curved trajectory, that is, it swings in substantially the same state as a rocking chair. That is, since the upper surface of the movable body 11 swings in a gently convex curved trajectory, the comfort provided to the user seated on the movable body 11 is improved.

On the other hand, the connecting member 18 that attaches the movable body 11 to the base body 1 is made of an elastic material such as rubber. Therefore, since the movable body 11 is elastically supported by the base body 1, it exhibits good cushioning properties due to the elasticity of the connecting member 19 when a user is seated on the seat portion 11a. Moreover, the movable body 11
swings back and forth against the restoring force of the connecting member 18. Therefore, even if the external force applied to the movable body 11 is large, the restoring force of the connecting member 18 prevents the movable body 11 from swinging too much. This prevents a user sitting on the table from being thrown off.

FIG. 5 shows another embodiment of this invention. In this embodiment, the connecting member 18 is formed using a coil spring 18a, which is an elastic material, instead of rubber. That is, tapered spacers 25 are fixed to both end surfaces of the coil spring 18a, and these spacers 25
The coil spring 25 is connected to the base pipes 8, 9 and the horizontal rod portion 17 of the armrest pipe 15 via these bolts 21.

Even in such a configuration, the same effects as when rubber is used for the connecting member 18 can be obtained.

Note that the connecting member is not limited to the front and back directions of the base.
The upper end may be inclined further outward than the lower end in the width direction as well. In this way, even when the movable body is swung in the width direction, the same effect as when swung in the front-rear direction can be obtained.

Furthermore, it goes without saying that this invention can be applied not only to chairs but also to beds, sofa beds, and the like.

[Effects of the invention] As described above, in this invention, the connecting member that swingably supports the movable body with respect to the base body is formed of an elastic material, and the upper end thereof is inclined more outward than the lower end. I did it like that. Therefore, the upper surface of the movable body swings while drawing a convex curved trajectory just like a rocking chair, allowing the user to enjoy a comfortable swing. Moreover, since the connecting member is made of an elastic material and its elasticity allows the movable body to have cushioning properties against the base body, this also improves the comfort provided to the user.
