To this end, the motion bed according to the present invention comprises: the upper body supporting unit supporting a user's upper body; a motor which rotates the upper body supporting unit up and down; and a control unit controlling the rotary speed of the rotary shaft of the motor for each stroke section of the upper body supporting unit.

Description

motion bed

The present invention relates to a motion bed, and more particularly, to a motion bed in which the angle of the upper body support part and the leg support part is adjusted.

In general, a bed is a furniture provided in a bedroom for a user to sleep, and is assembled by loading and fixing a mattress on a bed frame such as steel or wood. The mattress may be detachably attached to the bed frame so that it can be replaced with another mattress of the same standard or the same specification.

However, the mattress is a bed component that is substantially in contact with the user's body, and in order to give the user comfort, a plurality of spring members are disposed therein, and a plurality of spring members are weaved through a steel wire, etc. to form a predetermined appearance. After being manufactured to be equipped, it is provided to finish the exterior through a mattress cover made of fabric or cushion material.

Recently, mattresses are not manufactured in a traditional spring member-included method to pursue diversification of their functionality, but are made of latex or sponge materials with improved elastic properties. Attempts to add motion functions to mattresses are increasing.

For example, not a bed used at home, but a bed used in a hospital has a part of the frame that supports the user's body so that activities in the bed are supported without the help of external personnel such as a caregiver during the patient's rehabilitation and treatment period. It is provided to be adjustable.

Republic of Korea Patent Publication No. 10-2096779 (2020.04.03. Announcement) (hereinafter referred to as 'prior art') discloses a 'frame for a motion bed' in which a part of a frame supporting the body is provided so that the angle can be adjusted. have.

The prior art includes a basic frame, an upper body part, a central part, and a lower body part, and is provided so that the angles of the upper body part and the lower body part are adjusted by the operation of the upper body actuator and the lower body actuator installed on the basic frame, front and back on the base frame The moving frame to be moved may be moved as much as the upright angle of the upper or lower body through an operation associated with the upper or lower body, thereby providing comfort and comfort to the user.

However, in the prior art, the angle of the upper body is adjusted by moving the moving frame while the rotating shaft of the motor included in the upper actuator rotates at a constant speed. The motion bed of which the angle is controlled has a problem in that as the upper body part rises, the angle change of the upper body part and the moving speed of the moving frame rapidly increase, giving inconvenience to the user.

In order to solve this problem, the control unit 920 controls the rotation speed of the rotation shaft of the first motor 811 for each stroke section of the upper body support unit 300 so that the speed at which the angle of the upper body support unit 300 is adjusted is inconvenient to the user. can be controlled not to give

Hereinafter, in the control-related description, the second motor 821 for controlling the operations of the first leg support part 500 and the second leg support part 600 is excluded, and the operation of the upper body support part 300 is controlled. Since only the first motor 811, which is a configuration for the following, is used, the first motor 811 will be described as a motor 811 .

When the upper body support unit 300 is in a horizontally unfolded state as shown in FIG. 1 , the end of the rod 813 may be located at the first point P1 . When the upper body support part 300 is in a state of maximum angle adjustment as shown in FIG. 6 , the end of the rod 813 may be located at the third point P3 .

When the rotational speed of the rotating shaft of the motor 811 is constant, from when the end of the rod 813 is located at the first point P1, the rod 813 rotates the center of rotation C of the upper body support part 300.

Here, the third point P3 may be a point P3 at which the rod 813 is orthogonal to a straight line L passing through the center of rotation C of the upper body support unit 300 .

When the rotational speed of the rotating shaft of the motor 811 is constant, from when the end of the rod 813 is located at the first point P1, to the second point P2, the upper body support part 300 gradually slows down. It can be rotated based on the rotation center (C).

Through this, the motion bed 1 according to the embodiment of the present invention may be operated to provide comfort to the user. Specifically, the upper body support unit 300 may be angle-adjusted at a constant speed at the beginning, and then gradually slowly adjusted after the middle period, and then gradually and quickly adjusted at the end. Alternatively, the upper body support unit 300 may be angularly adjusted at a constant speed from the beginning to the end. Alternatively, the upper body support unit 300 may be angle-adjusted at a constant speed from the beginning and then gradually be adjusted at a slower speed at the end. Alternatively, the upper body support unit 300 may be angle-adjusted gradually and rapidly at the beginning, then at a constant speed, and then gradually adjust the angle at a slow speed at the end.
