Description

Height adjustable bed {A height adjustable bed}

The present invention relates to a height-adjustable bed, and more particularly, to a height-adjustable bed that has a structure that can be used to play as a play space in a normal way to prevent a child with a bad habit falling during sleep in the bed.

In general, a conventional bed is easy to be injured by a child or an adult who has a bad habit of falling off the bed while sleeping, and a guardrail having a predetermined height along both sides edges may be installed to prevent such an injury.

The conventional bed having such a configuration does not have a fall prevention structure at both ends, so when falling from the bed while injured, or when the guard rails installed at both sides are installed to prevent the above injury, Except for the difficulty of utilizing the upper surface of the bed, there was a problem that the height of the bed is high, the room in which the bed is placed can look narrow and give a frustrating feeling.

The present invention has been devised in view of the above-mentioned conventional problems, and its purpose is to prevent a child or a rough adult from falling asleep during sleep without special guard rails installed, and special limitations in normal times. The upper surface of the bed can be used freely, and the height is the same as that of a normal bed, so even if it is placed in a narrow room, it provides a height adjusting bed that does not feel narrow.

1 to 3, the height adjustment bed 10 according to the present invention is a main body 11, a plurality of lifts 12, 13, the support plate 14, the operating lever 15, It consists of a matrix 16.

The main body 11 is a housing having a hollow inside and having an open upper surface, and has a working hole 11a vertically penetrating with a predetermined width and length at a predetermined position at a lower end of one side.

The plurality of lifts (12) (13) is a screw shaft operation method that is generally used when replacing the wheel of the vehicle, etc., the both ends of the four operating members (a) are hinged rotatably to form a lozenge, The connecting portion of the upper and lower ends is supported by a fixing table (b) (c), and the connecting portions of both side ends are provided with a working nut (d) having a screw groove formed on the inner circumferential surface thereof, and a screw shaft (e) formed on the outer circumferential surface (e). ) Is screwed uniaxially with the opposing actuating nut d.

On the upper holder (b) of the lift 12, 13 having the structure as described above, the support members 12a, 13a having a predetermined size are fixedly attached horizontally, and the lower holder of the lift 12, 13 (c) is directly fixed to the inner bottom surface of the main body 11 so as to have a predetermined distance therebetween so that the actuating nut d is positioned on one axis, and the plurality of lifts are formed by a single screw shaft e. 12) The operating nut d of the 13 is screw-assembled so that each lift 12 and 13 is simultaneously moved up and down in accordance with the rotation operation of the screw shaft e.

One end of the strand shaft (e) is provided with a fastener (f) and is disposed on the operating hole (11a) side of the main body 11, is detachably fastened to the operating lever 15 is driven manually forward and reverse rotation do.

The support plate 14 is a plate having a predetermined size and is horizontally fixed on the support members 12a and 13a of the lifts 12 and 13 so that the lift 12 and 13 inside the main body 11. The lifting and lowering operation is performed according to the lifting and lowering operation of), and the matrix 16 is mounted on the upper surface of the support plate 14.

One embodiment of the height-adjustable bed 10 of the present invention having the configuration as described above uses the operation lever 15 after lying the child on the matrix 16 seated on the geothermal plate (14). By rotating the screw shaft (e) of the lift 12, 13 in one direction, the lift 12, 13 is respectively outwardly so that the operating nut (d) is opposed to each other by the rotation of the screw shaft (e) As it is moved, both connecting portions of the operating member (a) are folded and the upper and lower connecting portions are extended, so that the lifts 12 and 13 are lowered.

When the lifts 12 and 13 are lowered, the support plate 14 and the matrix 16 are lowered in conjunction with the lift 12 and 13 inside the main body 11, thereby supporting the support plate 14 and the matrix ( The side of the main body 11 is higher than the matrix 16 by the height of the lowered 16, so that the side of the main body 10 acts as a guardrail, even if the child sleeping in the bed 10 is badly flipped over the bed ( You can sleep comfortably without falling from 10).

In addition, the support plate 14 and the matrix 16 are lifted up to the upper surface of the main body 11 by raising the lift 12 and 13 by rotating the operation lever 15 in the opposite direction except for the sleep time. It can be used as a play space for children or a sofa space where people can sit.

4 shows another embodiment of the lift arrangement of the height adjustment bed 10 according to the present invention.

Lift arrangement structure of another embodiment that can be applied to the height adjustment bed 10 of the present invention is a parallel arrangement.

The parallel arrangements of the lifts 12 and 13 are provided with screw shafts 30 each of which the lifts 12 and 13 are independent, and are fixedly installed in parallel at predetermined intervals on the inner bottom surface of the main body 11. do.

One end of the screw shaft 30 each has a sprocket 31 of a predetermined diameter, the sprocket 31 is connected to each other by a drive chain 32 is connected to both ends circulated circulated have.

A fastener f is mounted on the screw shaft 30 of one of the lifts 12 and 13 and positioned in the operating hole 11a of the main body 11.

Lift arrangement method of another embodiment according to the present invention having the configuration as described above is rotated in one direction after fastening the operating lever 15 to the fastener (f) of the lift 12, of the lift 12 As the screw shaft 30 is rotated, the connecting portions of both ends are folded, and the connecting portions of the upper and lower ends are extended so that the lift 12 is lowered, and the screw shaft of the lift 13 is driven by the driving chain 32. 30 is also interlocked and rotated in the same direction so that the lifts 12 and 13 are simultaneously lowered to receive the support plate 14 and the matrix 16 into the main body 11. In addition, when the actuating lever 15 is rotated in the other direction, the lift 12 and 13 proceed in the reverse direction of the actuation and are lifted up to the support plate 14 and the matrix 16 to the upper surface of the main body 11. It can raise.

According to the present invention described above, it is possible to prevent children or adults who have a bad habit of falling out of bed while sleeping, without using a separate guardrail, and can freely use the upper surface of the bed without any special restrictions. It is the same height as the bed, so even if placed in a narrow room does not give a narrow feeling.
