Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention can be used for multiple purposes such as medical examination tables, pine surgery, general rest, or whole body beauty, pine surgery, treatments, and facials in beauty salons. To improve a multipurpose chair in which the backrest, the seat part, and the legrest can change from a horizontal state to a state in which the backrest and the legrest are inclined toward the feet.

[Conventional technology]

As a conventional multi-purpose chair of this type,
-10892 and those described in Japanese Patent Publication No. 56-10893 have been proposed.

However, with these multi-purpose chairs, when the backrest and the seatrest rest are tilted downward toward the feet from a bed-like state where the backrest and the seatrest rest are horizontal, the seat remains at the same height. It is something that goes up or down.

Further, although the modification operation is performed manually, even when this is performed using power, the drive mechanism is usually housed below the seat and backrest.

[Problem that the invention seeks to solve]

In the multi-purpose chair described in the above-mentioned publication, or in a multi-purpose chair with similar deformations, the mechanism for deforming the chair is not only complicated and expensive, but also frequently breaks down.

In addition, when sitting or lying down on this multi-purpose chair, it is shaped like a chair with the back and leg rests lowered, and after the patient is seated on it, it is transformed into the desired shape. It is.

However, when it is made into a bed, it needs to have a certain height, and the height of the seat cannot be lower than that, making it difficult to sit on it.

Furthermore, when performing full-body beauty treatments, facial treatments, etc. at a beauty salon, it is convenient for the practitioner to position the equipment on the chest of the recipient.

However, since the mechanism and drive mechanism for the above-mentioned transformation are provided below the seat and backrest,
The legs of the treatment equipment cannot be inserted or installed in this location, and the equipment is installed at a distance from the practitioner, making it difficult to operate the equipment and causing pipes, cords, etc. to be stretched long. This caused an unavoidable inconvenience.

[Means for solving problems]

The present invention is intended to solve the above-mentioned problems of conventional multi-purpose chairs, and allows the transition from the chair form to the bed form by power using a simple mechanism, and when the chair form is formed, the seat The object of the present invention is to lower the patient's body so that it is easy to sit on the patient's body, and to make it possible to install treatment equipment on the chest of the patient and to make it easier to operate the device.

The present invention is intended to achieve the above object, and its means include a backrest substrate, a seat substrate hinged to the backrest substrate, and a leg rest substrate hinged to the seat substrate. , a base provided with a pivot that rotatably supports the backrest board at a position away from a hinge point with the seat; and an extendable base that connects the base with the backrest or the seat. This is achieved by a multi-purpose chair equipped with a cylinder and a connecting rod that connects an arm rod fixed to a legrest base plate and a base.

[Effect]

When the multi-purpose chair of the present invention is in the form of a chair, when the seat is pushed up by extension of the telescoping cylinder, the backrest is rotated horizontally about the pivot.

At this time, the seat moves forward, so the hinge point of the leg rest with the seat also moves forward, and the connecting rod rotates around the connection point with the base, and as it rotates, Since the arm rod also rotates, the legrest rises while becoming horizontal, and the backrest, seat, and legrest are aligned horizontally at the same height on the axis, and the bed shifts to the bed form.

When the telescopic cylinder contracts from this bed form, it performs the opposite operation and returns to the chair form.

〔Example〕

An example of the implementation of the invention will be described below with reference to the drawings.

The base of this multi-purpose chair supports a pivot 5 at the upper end, and has a support pipe 1 and a stand 4 connected on both left and right sides by a connecting pipe 3 having a stand 3a at the lower end.
The base connecting pipe 2 connects the connecting pipe 4 and the connecting pipe 3 and is curved in an arc shape to form a space below.

A seat base plate 10 is bendably hinged to the front end of the back base base 11, and the back base base 11 is pivoted on a pivot 5 at a position away from the hinge point of the seat base base 10. It can be installed freely.

A leg rest board 1 is provided at the front end of the seat board 10.
2 is foldably hinged. Further, a telescopic cylinder 8 is mounted between a mounting bracket 9 provided on the lower surface of the backrest base plate 11 and a mounting bracket 7 provided on the support pipe 1.

This telescopic cylinder 8 is supplied with oil pressure by the rotation of a motor housed in the storage box 16, and expands due to the oil pressure, but contracts when the oil pressure is reduced.

An arm rod 19 is provided on the lower surface of the leg rest board 12.
is fixed, and this arm rod 19 and the connecting pipe 4 of the base are connected by a connecting rod 2 that is rotatable relative to each other.
Connected with 0.

On the backrest substrate 11, the seat substrate 10, and the legrest substrate 12, there is a mat 1 that can be bent locally.
3,14 are laid out.

Furthermore, armrests 1 are provided on both the left and right sides of the pivot 5.
The rear end portion of the armrest 15 is rotatably fitted into the armrest 15, and the front end portion of the armrest 15 is slidably fitted into a guide pipe 17 fixed from the upper part of the leg rest 12 toward the rear.

A pillow 18 is provided on the mat 13.

In this multi-purpose chair, when the chair is configured as shown in FIG. 1, the motor rotates, hydraulic pressure is supplied to the telescoping cylinder 8, and the telescoping cylinder 8 extends.
The backrest base plate 11 is pushed upward and forward as shown in FIG.

Then, the hinge point of the seat base plate 10 with the backrest base plate 11 moves forward and upward, so that the seat base plate 10 rotates about the pivot 5 in a horizontal direction.

At the same time, the leg rest board 12 also
Since the hinge point moves forward and upward, it moves forward and upward while rotating the connecting rod 20 around the connecting pipe 4.

At this time, due to the shifting relationship of the connecting point 6 between the connecting rod 20 and the arm rod 19, and the hinge points between the leg rest board 12 and the seat part board 10, the arm rod 19 connects the leg rest board as shown in FIG. Rotate it in the horizontal direction.

In this manner, at the time when the telescopic cylinder 8 has finished being extended, the backrest base plate 11, the seat portion 10, and the leg rest base plate 12 form the same horizontal plane, forming a bed.

As the leg rest board 12 is moved, the arm rest 15 is slidably inserted into the guide pipe 17 fixed thereto, so that the arm rest 15 is moved around the pivot 15 as shown in FIG. It rotates in the horizontal direction while sliding on the pipe 17.

When the armrest 15 has finished rotating until it becomes horizontal, it becomes the same horizontal plane as the mats 13 and 14 laid on the horizontal backrest substrate 11, seat substrate 10, and legrest substrate 12,
It becomes part of the top surface of the bed.

When the pressure inside the telescopic cylinder 8 is released and the telescopic cylinder 8 is contracted from the bed configuration shown in FIG. 3, each part operates in the opposite manner to the above to form the chair configuration shown in FIG. 1.

Therefore, when the patient is seated in the chair form of FIG. 1, the seat base plate 10 is lower than the bed form, making it easy for the person to sit on the chair form.

In the case of transitioning to the intermediate form shown in FIG. 2, the angle and height of the face can be set to be suitable for performing facial work at a beauty salon.

Furthermore, when the bed configuration shown in FIG. 3 is used, the seat base plate 10 is raised to a higher height than when the chair configuration is used, so the patient can be placed supine at a height suitable for pine surgery, medical treatment, etc. It is something.

In addition, in this embodiment, as described above, the armrest 15 has been described as having the function of serving as an armrest when it is in the form of a chair, and also has the function of widening the bed surface of the mats 13 and 14 when it is in the form of a bed. 15 is Letgrest 12
Any material may be used as long as it can function as a buffer by expanding and contracting.

Moreover, since the armrest 15 is positioned higher than the seat base plate 10 when it is in the form of a chair,
It is used as an armrest, and when it is in the bed form, it becomes the same horizontal plane as the mats 13 and 14,
It becomes part of the bed surface and can expand the bed surface.

〔Effect of the invention〕

As mentioned above, the present invention can be made into a chair form, a bed form, and an intermediate form, so it can be used for medical treatment tables, pine surgery, general rest, and full body beauty, pine surgery, treatments, and facials at beauty salons. It can be used for multiple purposes such as

Since the middle position of the backrest is supported by a pivot, the height of the seat is lower when it is in chair form, making it easier to sit on, and when it is in bed or intermediate form, the seat rises. , the height is suitable for the treatment, making it easier to perform the treatment.

Moreover, since this type of shape change is performed by power, it is easy to operate, a telescopic cylinder is sufficient as the drive mechanism, and the deformation mechanism is simple, so it can be provided at low cost and there is no risk of failure. .

Furthermore, due to the simplicity of the mechanism, it is possible to create a space on the floor below the seat and backrest.
The legs of the treatment equipment can be placed in this space, the treatment equipment can be positioned on the chest of the practitioner, and the treatment can be performed.

Therefore, the practitioner working near the face of the patient can reach out and operate the treatment equipment, and has the effect of being able to perform the treatment without having to walk around.
