Description

[Detailed explanation of the invention] (Purpose of the invention and problems with the prior art) This invention is an effective simple weighing device that allows elderly people who have difficulty moving their bodies on their own and hospitalized patients to easily measure their weight. It concerns a weighing chair.

BACKGROUND ART During treatment and examinations in hospitals, it is necessary and continuous to weigh inpatients as a document for doctors' medical records.

Hakari, which is conventionally used for weighing in hospitals, places the patient on a platform scale, or for patients with serious illnesses or elderly people who are unable to move, a wheelchair is placed on the platform scale by an attendant. At this time, accurate weighing cannot be performed unless the feet that are on the floor are removed from the floor.

However, for patients who cannot move their legs, elderly people who lack physical strength, and seriously ill people, it may be painful and impossible to raise their legs even slightly.

Another drawback is that it places a heavy physical burden on the nurses who attend the weighing.

This device was developed by the applicant with the aim of solving the above-mentioned difficulties in the structure of the scales currently used for weighing hospitalized patients. It is.

(Structure and Embodiments of the Present Invention) The gist of the present invention is to attach a seat section with a weighing scale built-in to the upper part of the seat frame of the chair body, and attach the seat section to the connecting shaft attached to the side frame of the seat section. A simple weighing system in which a chair-shaped rocking body bent along the body is pivotally supported and assembled integrally with the chair body, and the weight is measured when the lower end of the rocking body leaves the floor. It is related to chairs.

A suitable embodiment of the present invention will be illustrated and explained below.
In the drawings, reference numeral 1 denotes a main body of a chair body showing an embodiment of the present invention, and the frame structure may be a known chair body formed into an appropriate shape. A movable wheel 2 is attached to the rear leg body, and a rubber cap 3 is fitted to the base of the front leg body so that an accompanying assistant or the like can freely push and move a patient or the like sitting on the chair body.

4 is a seat frame of the chair body 1, and a seat part 5 shown in FIG. 2 is mounted on this frame so as to overlap. In the seat part 5, a weight scale 8 is installed in a container frame 7 provided at the lower part of the seat frame 6, and a seat cushion 9 is attached to the top surface of the scale. 10 is a connecting shaft attached to both ends of the seat frame 6, and a swing frame 11 is attached to the connecting shaft.
to support.

The swinging frame is a frame bent along the main body frame 1 of the chair body, and is attached to the chair body 1 together with the seat part 5 so as to swing back and forth about the connecting shaft as a fulcrum. The upper part 11' of the swinging frame is mounted upright along the backrest of the chair body with a slight spacing therebetween. The lower part 11" is a thin plate flap 1 installed below the legs of the chair body, and usually installed horizontally at the lower end.
2 is placed so that it is in contact with the floor. The flap 12 is pivotally supported by a pivot pin 13 so that it can be turned upside down. Reference numeral 14 is a stool installed on the seat frame 6, and reference numeral 15 is an audio or digital measuring instrument meter attached to the chair. 16 is a lead wire electrically connected to the measuring instrument 8.

The meter is equipped with an automatic weighing meter that includes a battery. 18 is a cushion. The seat part 5, which has the weighing scale 8 installed therein, is connected to a chair-shaped swinging frame 11 that is pivotally supported thereon, and is mounted on the seat frame 4 of the chair body, as shown in FIG. The seat part and the seat frame are connected at the four corners by connecting rings 17 and assembled into an integrated weighing chair body.

In this case, the connecting ring is a floating ring connected to the swinging frame so that it can swing slightly back and forth.

The swinging frame is designed so that when the load of a human body sitting on the cushion is placed on the upper frame 11' behind the backrest, the swinging frame swings backward and the flap 12 is moved away from the floor 19. The flap 12 is 5 points above the floor level.
It is designed to be easy to use and has a structure that does not put a burden on the patient who can float about 1 mm. Also, when the swinging frame swings backward and the flap rises, frame 1 remains upright.
Since the lower end of the bent base 20 of 1' comes into contact with the seat frame 6 and prevents it from swinging, the user's weight can be accurately measured by riding directly on a weighing scale attached to the seat of the chair body.

Note that the design may be changed as appropriate in terms of material and structure, and the present invention is not limited to this embodiment.

(Effects of the present invention) The present invention is a new weighing chair assembled into the above-mentioned structure, and even a weak patient or a hospitalized patient who cannot move due to a leg injury can sit on the weighing chair of the present invention and weigh the weight. If you hang it up behind you, the flap on which you rest your legs will rise slightly above the floor, making it easy to measure your weight as you stand on the scale. In this case, the flap is usually a thin plate that is in contact with the floor, so you can easily put your feet on the flap and sit on the chair without raising your feet. Also, in the swing frame, the back frame 11' comes into contact with the backrest of the chair body. Since the seat frame 6 of the seat section functions as a stopper to prevent the swinging frame 11 from swinging as described above, the weight of the human body on the seat is not affected by the chair body, but by the patient. This has the advantage that accurate weighing can be done simply by leaning against the swinging frame behind it.

Furthermore, the chair of this invention is structurally simple and movable, and weighing, which conventionally required the labor of two or three attendants or assistants, can now be done with the light work of one assistant. Therefore, it is highly practical and extremely effective as a weighing chair that simplifies handling and saves labor.
