CONSTITUTION:When a state of a chair is converted to that of a bed, a screw rod 21 of a back rest body angle adjusting member 22 and a screw rod 30 of a head rest body angle adjusting member 31 are pivotally operated, the back rest body 15 and head rest body 24 are set to the vertical position relative to a seat body 4, a screw rod 12 of a waste rest body angle adjusting member 13 is pivotally operated to set a waist rest body 7 approximately horizontally relative to te seat body 4. On the other hand, a screw rod 39 of a foot rest body angle adjusting member 4 is operatively pivoted to set the foot rest body 33 horizontally same as the seat body 4, and then a screw rod 47 of a foot rest body angle adjusting member 48 is pivotally operated to set a foot rest body 41 horizontally relative to the seat body 4. In the state of either chair or bed, respective drive motors 51, 61, 71, 81, 91 for respective desired expansible means 50, 60, 70, 80, 90 of bodies are driven so that the head rest body 32, head rest body 24, back rest body 15, foot rest body 33 and foot rest body 41 can be extended and contracted to each other.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bed-type chair, which is used for medical treatment in hospitals, for commercial purposes such as barbering and beauty, and for office and home use.

``Prior art'' Conventionally, in hairdressing chairs (Utility Model Application No. 63-54345) and dental treatment chairs (Utility Model Application No. 63-46125), the seat has a backrest and a branch. It has been proposed that the foot rests can be rotated to desired angles.

However, although the backrest and other parts of these chairs rotate relative to the seat, none of the parts turn into a complete bed, and each part, such as the backrest and footrests, is individually moved. Since the chair does not extend or contract, it has drawbacks such as the inability to adjust each part to fit each person's body when in the chair position.

``Object of the present invention'' In view of the shortcomings of the conventional technology, the present invention aims to improve the everyday life of a chair.
Based on the idea of ergonomics, taking into consideration the historical background such as dealing with an aging society and dealing with long hours of desk work due to the spread of office automation equipment, the chair can be used as both a chair and a bed. In order to fit each user's body, the waist support can freely expand, contract, and rotate each part of the body, such as the backrest, the head support, and the multiple foot supports. The objective is to obtain a bed-type chair that can be used in various industrial fields such as beauty, office, and home.

"A Means to Solve the Purpose" The bed-type chair of the present invention includes a seat body, a waist support that is pivotally supported by the seat body and rotates by a waist support angle adjustment member, and a body;
This waist support includes a backrest body that is attached to the body so as to be extendable and retractable directly or via a first horizontal lever and rotated by a backrest body angle adjusting member, and a backrest body that is extendable and retractable directly or via a second horizontal lever. A head holder that is movably attached to the body and rotated by a head holder angle adjusting member is attached to the body, and a first leg holder angle adjusting member that is extendably and retractably attached to the seat body directly or via a third horizontal rod. A first foot holder that rotates with the body, and a second foot holder that is attached to the body so as to be extendable and retractable directly or via a fourth horizontal rod, and that is rotated by a second foot holder angle adjustment member. The second foot rest is characterized by comprising a body.

"Function" When changing from the chair state shown in FIG. 1 to the bed state shown in FIG. 4 or 5, for example, the screw rod 21 of the backrest body angle adjustment member 22 and the first head support body angle adjustment member 31 screw rods 30 are rotated, and the backrest body 15 is
and the first head rest 24 are placed perpendicular to the seat body 4, respectively. Then, the screw rod 12 of the waist receiver angle adjustment member 13 is rotated to tilt the waist receiver until the body 7 is approximately parallel to the seat body 4.

On the other hand, the screw rod 39 of the first foot receiver angle adjusting member 40 is rotated to make the body 33 of the first foot receiver parallel to the seat body 4, and then the second foot receiver angle adjusting member 48 is rotated. The body 41 of the second foot rest may be made horizontal with the seat body 4 by rotating the screw rod 47. Therefore, the bed-type chair By driving 51, 61, 71, 81, and 91, respectively, the second head rest becomes the body 32, the first head rest becomes the body 24, the backrest body 15, the first foot rest becomes the body 33, and the second head rest becomes the body 32. The foot rests allow the bodies 41 to extend and contract with respect to each other.

"Effects of the Present Invention" As is clear from the above description, the present invention has the following effects.

(1) Each threaded rod 1 of the angle adjustment member for winter holidays such as the backrest body
By rotating 2.21.30.39.47, winter vacation can be set to suit each person's body.

(2) You can freely change the form from a tf4 child to a bed or from a bed to a chair.

(3) At least the seat body is 4, the waist support is 7, and the backrest is 15.
The first head rest is divided into six parts: the body 25, the first foot rest is the body, and the second foot rest is the body 41, and the winter vacation can be rotated to the desired angle, so it can be used in hospitals, etc. For the treatment of
It can also be used for professional purposes such as barbering and beauty, as well as office and home use.

(4) The waist support has a first horizontal rod 16 between the body and the backrest body 15, and the backrest body and the first footrest have a second horizontal rod 25 between the body 24, and Since a third horizontal rod 34 is interposed between the seat body and the first leg rest 33, the winter rest 15.24.33 can be extended and contracted to a desired position. At the same time, winter vacation 15.24
．． 33 can be rotated to a desired angle.
