Abstract

PURPOSE:To always make a reclining chair stable and to smoothly incline a back-rest part by providing a connecting member, whose one end is pivotally joined on the back-rest part and the other end is pivotally joined on a foot-supporting part, at the position lower than that of a pivot between the back-rest part and a seat plate part. CONSTITUTION:Each of the front ends of seat frame members 5, 5' is pivotally joined to each of the points of both leg parts of a U-shaped foot-supporting frame 6, and pivotally supporting arms 8, 8' are fixed on the rear face of a foot-supporting bar 7 provided between both legs of the foot-supporting frame 6. The pivotally supporting arms 8, 8' are pivotally supported at the points of both leg parts of a U-shaped supporting member 11 and the leg parts are slidably inserted separately in a pair of tubular members 10, 10' fixed on a supporting plate 9 provided between both sides of a supporting frame 1. On the other hand, on the rear face of the central part of the foot-supporting bar 7, a pivotally supporting lever 12 is fixed, and between this pivotally supporting lever 12 and a pivotally supporting lever 3a fixed on the under surface of a bottom-reinforcing member 3, a connecting member, or a link 13 is pivotally joined. As for the reclining chair, it is possible that a back-rest part 2 is inclined to the position shown in two-dot chain lines and at this time, the seat frame member 5, 5', the front-supporting frame 6, the supporting member 11 and the connecting member 13 are placed at the position shown in the two-dot chain lines. In this way, the state of a seating person can be turned into a lying state from its seating state as the person is on the seat.

Description

[Detailed description of the invention] Technical field The present invention relates to a supine chair.

BACKGROUND ART A reclining chair is disclosed in Japanese Unexamined Patent Publication No. 154185/1985 filed by the present applicant.

Such a supine-adjustable chair has the disadvantage that it has a large number of parts and is expensive.

SUMMARY OF THE INVENTION Accordingly, the present invention aims to provide a low cost supine chair.

Composition of the Invention The reclining chair according to the present invention includes a machine frame to be placed on the floor, a seat rest pivotally supported at the rear of the machine frame, and a rear end pivoted at the lower end of the front rest member. a seat plate portion that is attached to the seat plate; a foot support that is pivotally connected to a front end of the seat plate member and is rotatable from a position hanging from the seat plate member in a range substantially in a plane with the seat plate member; and the foot support a longitudinal member pivotally connected at one end to the back surface of the machine frame; a cylindrical member slidably fitted onto the longitudinal member and fixed to the front part of the machine frame; the backrest portion and the seat plate portion; The connecting member further below the pivot center position has one end pivotally connected to the backrest portion and the other end pivotally connected to the foot support portion.

Effect of the Invention According to the supine adjustable chair according to the present invention, the seat rest and the seat plate are configured to move forward and backward as the seat rest is tilted and raised, similar to the above-described conventional supine adjustable chair. Therefore, regardless of whether the seated person is in a supine or standing position, the seated person's center of gravity does not fluctuate greatly in the front-back direction of the chair, and the chair is always stable.Moreover, the seat rest is smooth and does not require recovery elastic force. Allows for tilting.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 4.

A reclining chair according to an embodiment of the present invention includes a frame 1 made of, for example, a vibrator member, and the frame 1 is installed on a substantially horizontal flat surface such as a floor via its legs la, la. The upper part of the frame 1, that is, the armrest is part 1b.

At the rear end pivot parts 4, 4' of 1b, a backrest part 2 made of a substantially U-shaped pipe member is pivotally supported with a slight portion left at its lower end. A bottom reinforcing member 3 is fixed between the lower end portions of the backrest portion 2. This bottom reinforcing member 3 rotates about its center line together with the pivoting at the rear end pivot portions 4, 4' of the backrest portion 2. The seat frame members 5, 5', which together with the bottom reinforcing member 3 form the seat, are pivotable at their rear ends at the point where the backrest 2 and the bottom reinforcing member 3 are fixed.

On the other hand, each of the front ends of the seat frame members 5 and 5' has a U-shaped foot support frame 6.
It is pivotally connected to each of the tips of both legs of the foot support 6, and is installed between the both legs of the foot support 6.
' is fixed. The pivot rod 8.8' is a pair of tubular members 10.1 fixed to a support plate 9 installed between the frame 1.
The U-shaped support member 11 is slidably inserted into the U-shaped support member 11, and is pivotally supported at the tips of both legs. On the other hand, a pivot rod 12 is fixed to the back surface of the central part of the foot support 7, and a link 13 is connected between this pivot rod 12 and a pivot rod 3a fixed to the lower surface of the bottom reinforcing member 3. are pivotally connected.

Further, the tubular member 10 can be freely reduced in diameter, and the lever 1
By rotating the lever 14, the diameter of the tubular member 1 can be controlled by a flexible wire (not shown) that is movable within the flexible sheath 15.
0 is reduced in diameter and tightens the support member 11 to form a stopper for the entire movable part including the backrest part 2.

The backrest portion 2 and the seat frame members 5, 5' are provided with a suitable right eye (not shown) to enable a person to sit on the seat.

In the reclining chair having the above-mentioned configuration, as is particularly clear from FIG. 4, it is possible to tilt the backrest portion 2 to the position indicated by the two-dot chain line, and in this case, the seat frame member 5.
5', the foot support 6, the support member 11 and the communication member 13 reach the position shown by the two-dot chain line. Therefore, the seated person transitions from the seated state to the supine state while remaining seated. Note that even if the tubular member 10 is not made to have a diameter that can be reduced freely, but is made into a rigid sleeve, and the stopper is omitted, the backrest portion 2
It was found that the tilted state was maintained and it was sufficiently practical.

Effects of the Invention As described above, in the reclining chair according to the present invention, the backrest is pivotably supported on the frame member that is stationary on the floor, and the seat is supported at a position below the pivot point of the backrest relative to the frame member. Moreover, this seat part is supported on the frame member so as to be able to move freely in the front and back direction, and the leg support is pivotally attached to the tip of the seat part, so that it changes from a vertical position to a horizontal position according to the tilting of the backrest part. Since the seat is connected by a link, when the seated person tilts the backrest while seated, the seat moves forward, and even if the backrest is tilted, the seated person's center of gravity relative to the chair hardly moves, making the chair stable. Furthermore, the rise and fall of the seat portion is linked to the tilting and rising motion of the backrest, and the backrest can be tilted and raised extremely smoothly.

Further, in the chair according to the present invention, each member is formed of a pipe member, which gives a casual impression as a whole, which is preferable.
