Abstract

PROBLEM TO BE SOLVED: To provide a pillow with which a comfortable sleep can be provided by changing a form corresponding to the taste or physique of a user by providing a height adjusting means for adjusting the height of a holder for holding the head and an operating means for operating the height adjusting means. SOLUTION: When an operating knob 17 is turned forward, a driving rod 7 is rotated, and a bearing 16 to be screwed with a male screw 8 is moved to right. Since one end of the driving rod 7 is supported by a bearing 15, the distance between the bearings 15 and 16 is extended and driving plates 6a and 6b are turned with a pin 9 as a center and pull down a holder 4 so that the pillow can be made low. In this case, since the one-side ends of the driving plates 6a and 6b are supported by supporters 10 so as to be freely rotated and the other-side ends are supported by sliders 12 so as to be freely rotated and are moved outside while being guided by shaft bodies, the holder 4 and a base part 5 smoothly follow up the motion of driving parts 6. When the operating knob 17 is turned backward, the driving rod 7 is rotated backward and since the gap between the bearings 15 and 16 is reduced, the driving plates 6a and 6b are turned with the pin 9 as a center and push up the holder 4 so that the pillow can be made high.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a use state of a pillow 1 according to the present invention. The pillow 1 is covered with a cover 2 as shown in the sectional view of FIG. 2, and a cushion member 3 and a head are supported inside. A support 4 and a height adjusting means A for adjusting the height of the support 4 are arranged, and an operating means B for operating the height adjusting means A is provided outside.

The cushion material 3 is formed of an elastic member such as urethane foam so as to cover the support 4 and the height adjusting means A. The cushion material may be arranged only on the upper surface of the support 4.

As shown in FIG. 3, the height adjusting means A is made of a synthetic resin such as plastic or a light metal such as aluminum in the shape of a long plate, and the central portion is slightly inward toward the center so that the head is stable during use. A support 4 formed in a curved shape,
It is composed of a drive portion 6 and a drive shaft 7 which are arranged between a base portion 5 formed of a synthetic resin such as plastic or a light metal such as aluminum in a long plate shape.

A substantially L-shaped support piece 10 is fixed near one end of the opposing surfaces of the support 4 and the base 5, and a slot 11 is formed near the other end. A substantially L-shaped sliding piece 12 is arranged. This sliding piece 12 is shown in FIG.
As shown in (a), the elongated hole 11 engages with the shaft bodies 13 formed in the support body 4 and the base portion 5, respectively.
Is guided so as to be movable in the longitudinal direction. A bulge 14 is formed at the end of the shaft 13 to prevent the shaft 13 from coming off.

The drive portion 6 is composed of two drive plates 6a and 6b. The center portions of the drive plates 6a and 6b intersect in an X shape, and the intersecting intersections are rotatably supported by a pin 9. The sliding piece 12 is supported and has one end fixed to the support piece 10 fixed to the support 4 and the base 5, and the other end slidably arranged between the support 4 and the base 5. Are rotatably supported by each of them (see FIGS. 4 (a) and 4 (b)).

As shown in FIG. 2, the drive shaft 7 is engraved with a male screw 8 in the vicinity of its center, one end of which is supported by a bearing 15 which is rotatably supported by the drive plate 6a. A bearing 16 rotatably supported by the drive plate 6b and engraved with a female screw.
The operation knob 17 which is the operation means B is attached to the pillow by screwing it to the outside of the pillow.

According to the pillow having the above structure, the drive shaft 7 rotates when the operation knob 17 is normally rotated as shown in FIG. When the drive shaft 7 rotates in the forward direction, the bearing 16 is screwed into the male screw 8 and moves in the direction of arrow a. Since one end of the drive shaft 7 is supported by the bearing 15, the distance between the bearing 15 and the bearing 16 increases, and the drive plates 6a and 6b rotate about the pin 9 and the upper end moves downward, so that the support 4 The pillow can be lowered because it is pulled down. It should be noted that one end of each of the drive plates 6a and 6b is rotatably supported by the support piece 10, and the other end is rotatably supported by the slide piece 12, and the slide piece 12 is connected to the shaft body 1.
The support 4 and the base portion 5 can smoothly follow the movement of the drive portion 6 because the guide portion 3 moves outward.

Further, when the operation knob 17 is rotated in the reverse direction, the drive shaft 7 is rotated in the reverse direction and the distance between the bearing 15 and the bearing 16 is narrowed, so that the drive plates 6a and 6b are rotated around the pin 9 and the upper end of the drive member is moved. Since it moves upward and pushes up the support 4, the pillow can be raised.

As described above, by operating the operation knob 17, the height of the pillow can be changed according to the physique (adult or child) of the user and his / her preference, and comfortable sleep can be provided. .

In the above-mentioned pillow, the drive unit 6 is composed of two drive plates 6a and 6b intersecting each other in an X shape, but as shown in FIG. 6, it is composed of four drive plates 20 in a pantograph shape. ,
The support piece 10 fixed to the support body 4 and the base portion 5 may be rotatably supported.

Next, another example of the pillow will be described. In this pillow, as shown in FIG. 7 (a), the first support member that supports the head is the first.
Of the side plate 4 and the left and right ends of the first support 41 are bent downward at right angles.
3 is formed, and is configured to move up and down by the height adjusting means A like the above-mentioned support. Left and right ends of the second support 42 are bent downward at right angles to form a side plate 44. The side plate 44 and the side plate 43 of the first support 41 are pivotally supported by a shaft 45, and the first support The second support 42 is provided so as to be rotatable forward and backward with respect to the body 41 (see FIG. 7B). A ball plunger 46 is arranged on one inner surface of one of the side plates 44, and is formed on the outer surface of the side plate 43 of the first support body 41 corresponding to the side plate 44 at an appropriate interval on the movement trajectory of the ball plunger 46. It is provided so that the second support body 42 can be locked by engaging with the engaged recess 47.

According to the pillow having the above structure, the operation knob 17 is turned to operate the height adjusting means A to adjust the height of the first support 41. After adjusting the height, the second support body 42 is forcibly rotated in the front-rear direction against the spring (not shown) of the ball plunger 46, and the second support body 42 is rotated at the optimum angle for stabilizing the head. Stop motion. The ball plunger 46 is an engaging recess 47 formed in the side plate 43 of the first support body 41.
, The second support body 42 can be fixed in a stable state of the head, and a pillow for more comfortable sleep can be realized.

[0020]

According to the pillow of the present invention, by turning the operation knob, the height of the pillow can be easily adjusted according to the preference and the physique of the user, and a comfortable sleep can be obtained. Can be provided.

By adjusting the angle of the support for supporting the head, the user's taste and physique can be adjusted and the head can be stabilized, so that more comfortable sleep can be obtained.
