On the other hand, the height adjustment pillow according to the second embodiment of the present invention, there is a difference that does not have a load detection means.

The load cell 16, which is a load detection means presented in one embodiment, is for automatic height adjustment according to load value detection. The present invention provides automatic operation as in the first embodiment with respect to the height adjustment of the pillow and a mode according to the second embodiment It is possible to select a semi-automatic operation mode by operating the selector switch 70.

Reference numeral 40 is a "bracket" for fixing the mover 15 to the base plate 20.

Reference numeral 41 denotes a “roller” for smoothing the sliding motion when the screw holder 31 moves along the surface of the base plate 20.

Reference numeral 42 is a "bracket" for fixing the link 33 rotatably on the baseplate 20.

Reference numeral 43 is a "rotational shaft" rotatably coupling the movable capital body 30 and the link 33, 44 and 45 are "pins", respectively.

Referring to the control flow chart of Figures 1 to 6 and Figure 7 attached to the operation of the height adjustment pillow according to the present invention configured as described as follows.

The present invention, as described above, with respect to the height adjustment of the pillow, the automatic type operation according to the embodiment to which the load detection means is applied, and the switch selection operation of the mode selection switch 70 simply by the load detection means, By semi-automatic operation by the two embodiments are divided. Therefore, the difference is divided into the one according to the load detection information (one embodiment) and the other one (second embodiment) in the height adjustment of the pillow, the rest of the mechanical operation and action is the same.

First, when the power source 50 is applied by operating the on-off switch 60, the power source is basically supplied to the control unit 17 and the drive unit 14 in which the circuit components and the microprocessor constituting the controller are mounted.

When a signal is input to the drive motor 24 according to the control signal of the controller 17, the screw shaft 13 engaged therewith is rotated, and the rotation of the screw shaft 13 is rotated by the rotary pulley 25 and the belt 26. ) Through another screw shaft (13a).

Under the condition that the screw shafts 13 and 13a are continuously rotated in position, the screw holder 31 of the mover 15 coupled thereto moves along the spiral direction machined to the screw shafts 13 and 13a. In addition, in proportion to the movement amount, the mover 15 rises in the direction of the arrow as shown in FIG. 2 while lifting the link 33.

For the sake of explanation, the arrow direction rotation of the mover 15, i.e., the upward movement, is the forward rotation of the drive motor 24.

The driving motor 24 is a motor controlled by the control signal of the controller 17, and the driving motor 24 is capable of driving time, standby, and forward and reverse rotation according to the setting of the controller 17. When the driving motor 24 rotates in this way, the other side mover 15 which is bitten by the same screw shaft 13 is also raised at the same rotation angle in proportion to the movement amount of the screw holder 31 as in FIG. 3. .

The mover 15 moves the screw holder 31 by the rotation of the screw shafts 13 and 13a during the forward rotation, and the end portion is lifted up by the amount of movement continuously to lift the top plate 11 to the lifted position. In the reverse rotation, the lower plate moves downward in the opposite direction to the arrow direction of FIG. 2 to finally move the top plate 11 to a sinking position.

The mover 15 may raise and lower the position of the top plate 11 coupled with the case 12 in the forward and reverse rotation of the driving motor 24 so that the user may move the top plate 11 to the height of the pillow. The position can be calibrated and used as needed. (This is by operating the switch. When the height of the pillow, that is, the top plate 11 reaches the desired height, the switch operation is stopped. It is the same as the operation of selecting the height by lowering the knob by operating the reverse rotation switch, which is a mixture of manual and automatic.)

On the other hand, the present invention is possible through the load cell 16 to automatically change the height of the top plate 11 in response to a change in posture during the use of the pillow.

The load cell 16 is mounted on the mover 15 and directly receives a load pressed from the top plate 11.

As shown in FIG. 3, the load acting on the top plate 11 by "W1" and "W2" is detected by the load cell 16. Here, the load of "W1" and "W2" is the amount of force in response to the pressure that the head or part of the body is entrusted to the surface of the pillow in response to the use of the pillow, the load cell 16 loads this pressing force Is detected and sent to the control unit 17, and the control unit 17 compares the input data value according to the value of the detection information to control the rotational direction corresponding to the rotational direction and the detection value of the drive motor 24.

Here, the technology of reading the load as a value and controlling the signal is a general range of technology. The important thing is that the top plate 11 automatically responds to the pillow after detecting the force pressed by the human body through the load cell 16. It is to adjust the height of the, through this, even without a separate operation during sleep, the height of the pillow itself is adjusted according to the posture change or position correction.

When the top plate 11 is pressed with too much force over the average value that is pressed on average, the force that is pushed in accordance with the change in posture means that the height of the pillow is higher than that of the appropriate standard, and it is necessary to lower and adjust it. And, the optimal position corresponds to the static position, that is, the reference value can be seen as no need to adjust the height anymore.

The reference value may be set based on the weight of the head of the body part, the weight obtained from a normal sleeping posture, and the weight according to various posture changes as data information.

4 is an example of arranging the movers 15 at four locations to detect the weight load of W1 / W2 / W3 / W4, which is an example of a preferred arrangement configuration of the present invention.

According to the present invention, it is possible to select the operation method by the switch circuit configuration shown in FIG. 5 and the mode selection switch shown in FIG.

Figure 7 is a control flow chart for explaining this with reference to the electronic control automatic height adjustment operation of the height adjustment pillow of the present invention, the position of the mover 15 is parallel to the base plate 20 of the case 12 The position is the initial reference position.

When power is supplied to the drive motor 24 (S100), the drive motor 24 is rotated forward and the mover 15 is raised in the initial horizontal position as shown in FIG. Starts to rise (S101).

The weight load detection by the load cell 16 is started by the load pressed by the human body (S102).

The information detected by the load cell 16 is compared with a reference value (S103). If the reference value is within the range, the power supplied to the driving motor 24 is cut off and waits (S104).

Here, when a change in the reference value occurs according to the change in the user's attitude (S105), a change in the reference value occurs and the reference value is again compared (S106).

If the reference value is exceeded, power is supplied to the drive motor 24 (S107), the drive motor 24 is rotated in the reverse direction to lower the height of the top plate 11 of the pillow (S108), and the reference value is again compared to the drive motor. The state of standby mode (S109) is maintained so as to be a continuous operation of controlling the drive power supply of (24).

On the other hand, semi-automatic operation that is distinguished from the automatic operation can be operated through the operation of the simple mode selection switch 70, as shown in FIG.

For example, (a) is the initial neutral position, (b) the height of the pillow, (c) the height of the pillow is lowered, the on-off switch 60 is turned on, and the mode selection switch 70 A), the power is applied to the driving unit 14, and the mover 15 raises and lowers the position of the top plate 11 coupled with the case 12 in accordance with the rotational direction of the driving motor 24. It is possible to give the user can use the position of the top plate 11, which is the height of the pillow, appropriately selected and corrected as necessary.

This is a type of operation in which the height of the pillow, that is, the top plate 11 stops the operation of the switch when it reaches the desired height, and if the height is too high, the operation of the switch lowers the operation motor 24 to reverse the drive motor 24 to select the height. Is the same as

As described above, according to the present invention, the height of the pillow according to manual and semi-automatic and weight loads can be varied by themselves, thereby enabling automatic operation to match the optimum height.

While the invention has been described in connection with the preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such changes and modifications are set forth in the claims. Belongs to the range.
