Abstract

PURPOSE:To enable a user to enjoy comfortable rocking by applying the constitution wherein a movable body is supported with an aslant wire and the upper surface of the body oscillates along a convex curved locus. CONSTITUTION:A movable body 7 located above a base body 1 has a box-like body 8 with the lower end thereof open and a storage part 11 is cellularly formed at both sides thereof with divisions 9 at both ends in the widthwise direction thereof. The axial line of a cylindrical lower restriction member 13 is made aslant at an angle of alpha outward toward the front and back sides of the base body 1 for a vertical line, similar to an upper restriction member 6. In addition, the upper restriction member 6 is kept in line with the axial line and one end thereof is weld fixed. Furthermore, the upper restriction member 6 and the lower restriction member 13 have both ends of wires 14 inserted and the upper end of each wire 14 is fixed to the bent part 5 of a crosspiece 4. The lower ends of the wires 14 are secured to a fixing member 12. As the upper surface of the movable body 7 moves along a locus opposite to the locus of the lower end of a pair of the wires 14, the movable body 7 locks along the semi-circular line of convex form with the leading end slightly coming lower than the trailing end, while locking forward.

Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION (Industrial Field of Application) The present invention relates to resting furniture such as beds, sofas or sofa-beds.

(Prior Art) Generally, resting furniture such as the bed, sofa, or sofa-bed is comprised of a base and a portion provided on the base for a user to sit or lie down 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 is lower than when that part swings like in a rocking chair, for example.

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 without 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-rear direction while bending the wire, the upper surface of the movable body is displaced in the front-rear direction while changing the 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 curve like the upper surface of a rocking chair, so a user sitting or lying on the movable body cannot enjoy the comfort that a rocking chair provides. That happened.

In addition, the movable body is swingably supported by wires,
If a large external force is applied, it will swing with a large amplitude in response to the external force. In that case, if the swinging of the movable body is not regulated in any way, there is a risk that the user may fall off the movable body.

Therefore, in order to restrict the swinging of the movable body so that it does not swing above a predetermined amplitude, it is conceivable to cause the movable body to collide with a stopper provided on the base body, for example. However, if the rocking of the movable body is restricted by colliding with a stopper, the impact at the time of the collision is large, which may cause discomfort to the user or cause the user to fall from the movable body.

(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 gentle convex curve like a rocking chair, so it did not have the comfort of a rocking chair. In addition, regulating the swinging of the movable body so that it does not swing with an unnecessarily large amplitude requires a large shock to be applied to the movable body, which also impairs comfort. There were times when I got caught.

This invention was made based on the above-mentioned circumstances, and its purpose is to be able to swing a movable body so that its upper surface draws a gently convex curved surface, and to allow the movable body to move more than necessary. To provide a piece of furniture for rest, which can be prevented from swinging with a large amplitude without giving a large impact to the movable body.

[Structure of the invention]

(Means and effects for solving the problems) In order to solve the above problems, the present invention has a base body and a movable body, and the movable body has an upper end connected to the base body and a lower end of a bendable connecting member. In the resting furniture that is connected to the base and is swingably provided, the connecting member is arranged such that the upper end thereof is inclined outward from the lower end, and at least one of the upper end or the lower end of the connecting member is arranged. At the end of
A regulating member that restricts the swinging of the movable body when the coupling member abuts is disposed opposite to an end of the coupling member.

With such a configuration, the movable body is allowed to swing so that its upper surface draws a gently convex curved surface, and the regulating member prevents the movable body from swinging with an amplitude greater than a predetermined amplitude. We have made it possible to regulate this without causing any major impact.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. 1 and 2 show a sofa as a piece of rest furniture, which sofa is equipped with a basic body 1. FIG. This base 1 is made up of a rectangular frame 2, a pair of vertical bars 3 erected on both sides of the frame 2 in the width direction, and a horizontal bar 4 installed horizontally on the upper end of the vertical bars 3. It is configured. Both ends of the horizontal beam 4 are formed into bent portions 5 bent downward at a predetermined angle α, as shown in FIG.
One end of a cylindrical upper regulating member 6 is fixed by, for example, welding, with its axis perpendicular to the bent portion 5. Therefore, the axis of the upper regulating member 6 is at a predetermined angle α toward the inside of the base body 1 in the front-rear direction with respect to the vertical line.
It is sloping.

A movable body 7 is arranged above the base 1 . This movable body 7 has a box-like body 8 with an open bottom surface. Partition plates 9 are provided along the front-rear direction at both ends in the width direction of the box-shaped body 8, and storage portions 11 are defined on both sides of the box-shaped body 8 by these partition plates 9.

Furthermore, rectangular cylindrical mounting members 12 whose upper surfaces are inclined at the same angle as the bent portions 5 are installed at the lower ends of both ends of the pair of partition plates 9 in the front-rear direction. Each installation requires member 12
A cylindrical lower regulating member 13 is provided on the upper surface of both ends protruding into the accommodation portion 1, and the axis thereof is directed outward in the front-rear direction of the base body 1 at an angle α with respect to the vertical line, similar to the upper regulating member 6.
One end is fixed by welding so that the upper regulating member 6 is aligned with the axis of the upper regulating member 6.

Both ends of a wire 14 serving as a connecting member are inserted through each pair of corresponding upper regulating member 6 and lower regulating member 13 coaxially with each regulating member 6.13. Each wire 14
The upper end is fixed to the bent portion 5 of the horizontal beam 4, and the lower end is fixed to the mounting member 12. That is, a total of four wires 14 provided at both widthwise ends of the base body 1 in the front-rear direction have their upper ends inclined outward in the front-rear direction than their lower ends at an angle α, and these four wires 14 The movable body 7 is swingably supported by the base body 1.

As shown in FIG. 3, each of the above-mentioned regulating members 6.13 has a circumferential wall formed in a rounded portion 15 whose diameter increases in a trumpet shape from one end fixed to the horizontal beam 4 or the mounting member 12 toward the other end. . Therefore, when the movable body 7 swings while bending the wire 14, both ends of the wire 14 come into contact with the inner surface of the rounded portion 15 of each of the regulating members 6.13.

A seat cushion body 16 is provided on the upper surface of the box-like body 8 constituting the movable body 7, and a backrest 17 is provided on the rear end side of the upper surface.
has been erected. This backrest 17 is covered by a back cushion body 18.

According to the sofa configured in this way, if a user (not shown) sits on the seat cushion body 16 and leans on the back cushion body 18 and applies a force in the front and back direction to the movable body 7, the movable body 7 will swing back and forth while bending the wire 14.

A wire 14 that swingably supports the movable body 7 on the base 1
is inclined at an angle α such that the upper end is located further outward than the lower end in the front-rear direction of the base body 1.

When the movable body 7 swings forward, the lower end of the wire 14 on the front end swings in the upward direction as shown by arrow a in FIG. 1, and the lower end of the wire 14 on the rear end swings in the upward direction as shown by the arrow Similarly, it swings in the upward direction. At this time, when comparing the amount by which the lower ends of the wires 14 on the rear end side and the wires 14 on the front end side are displaced in the vertical direction, it is found that the wires 14 on the rear end side whose lower ends are inclined toward the front of the base 1 The amount by which the wire 14 is displaced upward is larger than that of the wire 14 on the front end side whose lower end is inclined toward the rear of the base body 1. Then, within a predetermined range of amplitude, when the movable body 7 swings most forward, the lower end of the wire 14 on the front end side is displaced in the upward direction more than the lower end of the wire 14 on the rear end side. becomes slightly smaller. Therefore, since the upper surface of the movable body 7 traces a trajectory opposite to the locus of the lower ends of the pair of wires 14, the upper surface of the movable body 7 moves forwardly as the movable body 7 swings forward. It will swing while drawing a convex curved arc that descends slightly.

Moreover, when the movable body 7 swings backward, it follows a convex curved trajectory in which the rear end side slightly descends and the front end side rises, contrary to the forward swing. It will oscillate.

Therefore, the movable body 7 swings back and forth while its upper surface traces a gently convex curved trajectory, that is, it swings in almost the same state as a rocking chair. That is, although the upper surface of the movable body 7 swings in a gently convex curved trajectory, the comfort provided to the user seated on the movable body 7 is improved.

Note that the trajectory of the upper surface of the movable body 7 can arbitrarily set the curvature of the convex curved surface by changing the inclination angle α of the wire 14.

Furthermore, although the movable body 7 is not installed on the floor like a rocking chair, the frictional resistance during rocking is small, and as a result, noise and vibration are less likely to occur. Therefore, the movable body 7 swings quietly and smoothly. Furthermore, since there is less frictional resistance during swinging, the movable body 7 swings with less damping. In other words, the movable body 7 -
If excessive force is applied, it will oscillate for a long time.

On the other hand, when the movable body 7 swings, both ends of the wire 14 come into contact with the inner surface of the radiused portion 15 of the regulating member 6.13 and curve along the radiused portion 15. Considering the state in which the movable body 7 swings forward, the swing causes both ends of the wire 14 and each regulating member 6 to
．． 13's contact length with the rounded portion 15 gradually increases,
As a result, the free length of the wire 14 becomes progressively shorter. Then, the movable body 7 tries to displace from the front to the top, but
Since upward displacement requires a large amount of energy, upward displacement is likely, so even a slight upward displacement will restrict forward rocking and change the rocking direction to backward. .

Furthermore, if a large external force is applied to the movable body 7 inadvertently,
Since the swinging speed of the movable body 7 becomes faster, the above-mentioned operation is performed rapidly. At that time, the wire 14 of the movable body 7 comes into contact with the curved surface of the rounded portion 15, and the free length of the movable body 7 gradually becomes shorter, and the amplitude of the swing is regulated by shifting upward from the front-back swing. . Therefore,
The movable body 7 collides with the stopper as in the conventional method.
Since the swinging of the movable body 7 can be restricted without giving a large impact to the user, the user seated on the movable body 7 will not be given a large impact.

In addition, in the above embodiment, a trumpet-shaped cylinder was used as the regulating member 6.13, but the regulating member 6.13 is, for example, a fourth member.
As shown in the figure, a straight cylindrical body may be used, and only one end thereof may be formed in the diameter expanding direction to form the rounded portion 15a.

Further, as shown in FIGS. 5 and 6, the connecting member may be a strip steel plate 21 instead of a wire. When the band-shaped steel plate 21 is used as the connecting member, the band-shaped steel plate 21 curves in the thickness direction, but does not curve in the width direction. Therefore, the bending direction of the movable body 7 can be limited to one direction. Also,
The curve direction may be set to -22. This plate material 22 may be curved with a predetermined curvature to form the rounded portion 22a.

In addition, the upper end of the wire is inclined outward from the lower end only in the front-rear direction of the base body, but the upper end is also inclined outward from the lower end not only in the front-rear direction but also in the width direction. Good too. 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 the present invention can be applied not only to sofas but also to beds and sofa beds.

Further, the regulating member may be provided only at either the upper or lower end of the wire.

〔Effect of the invention〕

As described above, the present invention provides a wire that swingably supports a movable body with respect to a base body, and arranges the wire so that its upper end is inclined outward from the lower end, and that the upper and lower ends of the wire are At least one end portion is provided with a regulating member that regulates the swinging of the movable body by coming into contact with the connecting member. Therefore, since the movable body is supported by an inclined wire, the upper surface of the movable body swings smoothly while drawing a convex curved trajectory, just like a rocking chair, allowing the user to enjoy a comfortable rocking motion. Moreover, since there is less resistance during rocking than in a rocking chair, the movable body can be rocked favorably over a long period of time.

In addition, when an unexpected external force is applied to the movable body and it swings with an amplitude exceeding a predetermined value, the end of the wire comes into contact with the regulating member and changes the swing of the movable body from the horizontal direction to the vertical direction.
The swinging of the movable body is restricted.

Therefore, since the movable body is restricted from swinging without causing a large impact, it does not cause much discomfort to the user.
