Description

[Detailed Description of the Invention] This invention relates to a rotating device for a washing stand such as a rotating storage drawer type sink or a washstand for saving indoor space.

Conventionally, as a rotating storage drawer type washstand, both the left and right sides of the washstand are rotatably supported by a frame using pivots, and when in use, the washstand is rotated downward and placed in a horizontal position, and when not in use, the washstand is moved upwards. It is generally known that the washbasin has a structure in which it can be rotated and stored in an inverted state within a frame. The design required a considerable amount of space to allow rotation, and as a result, there was a drawback that sufficient space savings could not be achieved.

The purpose of this proposal is to provide a rotating device for a washing table that allows the rear end of the washing table to rotate within a small space.The features include a pair of left and right upper links on the upright wall of the frame, and the upper links. One end of each of the pair of left and right lower links is rotatably supported on a vertical plane below the base, and the other ends of the pair of upper links and the pair of lower rings are rotatably connected to the left and right side surfaces of the washbasin, respectively. The length of each node and the position of each node are determined based on the fact that the locus of movement of the upper end of the rear end of the washstand when the washstand rotates is approximately on an elongated arc. The locus of movement of the lower end of the rear end is approximately on a horizontally elongated arc.

Embodiments of the present invention will be described below with reference to drawings used for a sink.

In FIG. 1, a frame 1 is a box-like body with an open front, which is composed of a rear wall 2 that stands up, a left side wall that stands up, side walls 3 (the right side wall is not shown), a top plate 4, and a bottom plate 5. A pair of left and right upper brackets 6 are fixed to the center of the inner surface, and a pair of left and right lower brackets 7 are fixed below them, one end of the pair of left and right upper links 8 is attached to the upper bracket 6, and one end of the pair of left and right upper links 8 is attached to the lower bracket 7. one end of the lower link 9 of each is supported swingably on a vertical plane by a shaft 10.11;
The other ends of these upper and lower links 8 and 9 are connected to the sink 14
It is rotatably connected to the left and right sides of the body by shafts 12 and 13, respectively.

As an example, in this example, the axes 10, 11 are on the same vertical line, the distance between the two axes 10, 11 is 40 crn, and the upper link 8 is
The length of the lower link 9 is 28 cm, the length of the lower link 9 is 27 cm,
The distance between the axes 12 and 13 is 15 cm.

Now, when the sink 14, which is in a horizontal state as shown in the second figure, is rotated clockwise, the upper link 8 swings around the shaft 10, causing the shaft 12 at the tip to move on the arc a, and the lower link 9 swings around the shaft 11 and moves the shaft 13 at the tip in an arc, and the compound movement of these shafts 12.13 displaces the center of rotation of the sink 14, thereby causing the sink 14 to move in an arc.
The upper end 15 of the rear end moves on an approximately vertically elongated arc y indicated by a dotted line, and the lower end 16 of the rear end moves approximately on an elongated horizontally arc X indicated by a dotted line. When the upper end 15 is rotated approximately 90 degrees from the horizontal state to the vertical state shown by the imaginary line, the upper end 15 descends in a gentle curve from approximately the apex of the vertically elongated arc y to approximately the midpoint of the arc with a large radius of curvature on the right side, and The upper end 16 moves to the left in a gentle curve (rather, a curve close to a straight line) from approximately the midpoint of the lower side of the horizontally elongated arc X with a large radius of curvature to the left end.

As a result, the space that must be provided between the sink 14 and the rear wall 2 and under the sink for the rotation of the sink 14 can be greatly reduced.

In the present invention, by appropriately changing the design of the length of each node and the position of the node, the shape of the vertically long arc y and the horizontally long arc Various changes can be made depending on the purpose, such as making it possible to reduce the space above.

A faucet head 17 projects from the inner surface of the rear wall 2 to the upper surface of the rear end of the horizontal sink 14, and serves as a stopper to prevent the sink 14 from rotating further in the counterclockwise direction from the horizontal state.

18 is a faucet, 19 is a water receptacle provided below the sink, 20 is a drain pipe, and 21 is a drain hole at the rear end of the sink 14.

Incidentally, a catch male part 22 is provided protruding from the upper surface of both left and right sides of the sink 14, and a catch female part 23 which is to be removably fitted therewith is provided protruding from the inner surface of the rear wall 2, so that the sink 14 is stored in a vertical position. When the catch male part 22 and female catch part 23 are fitted together, the stored state is maintained.

According to the washing table rotating device of this invention, when the washing table is rotated, the upper end of the rear end of the washing table moves approximately on a vertically elongated arc, and the lower end moves on an approximately horizontally elongated arc, thereby moving the washing table and the rear wall. The space between the washing stand and the space below or above the washing stand can be greatly reduced, and accordingly, a compact rotating storage drawer type washing stand can be provided.

Claims (1)

[Claims for Utility Model Registration] A pair of left and right upper links and one end of each of a pair of left and right lower links below the upper links are rotatably supported on a vertical plane on an upright wall surface of the frame, and the pair of upper links The other ends of the pair of lower links are rotatably connected to the left and right sides of the washstand, respectively, to form a four-joint double-lever chain, and the length of each of the above-mentioned joints and the position of each node are determined according to the rotation of the washstand. The washing table rotating device is configured such that the movement locus of the upper end of the rear end of the washing table during washing is approximately on a vertically elongated arc, and the movement locus of the lower end of the right rear end of the washing table is approximately on a horizontally elongated arc.
