Hereinafter, look at the action and effect of the ship chair having a horizontal maintenance structure according to the first embodiment.

As seen from the front of the ship's traveling direction, as shown in Fig. 2, when the bottom of the hull is inclined forward, gravity acts vertically downward on the horizontal holding means 40 so that the inner frame 20 is rearward (B direction). Rotation of the sheet portion 30 is inclined backward so that the sheet portion 30 is horizontal.

As shown in FIG. 3, when the bottom of the hull is inclined backwards, gravity acts vertically downward on the horizontal holding means 40 so that the inner frame rotates forward (F direction), whereby the seat portion 30 is It is inclined forward and the level of the seat part 30 is maintained.

As shown in FIG. 4, when the bottom of the hull is inclined to the left, gravity acts vertically downward on the horizontal holding means 40 so that the seat 30 is rotated and tilted to the right (R direction) so that the seat portion ( 30) is maintained horizontal.

As shown in FIG. 5, when the hull is inclined to the right, gravity acts vertically downward on the horizontal holding means 40 so that the seat 30 is rotated and tilted to the left (L direction) so that the seat 30 is inclined. Is kept horizontal.

When the bottom of the hull is inclined forward and also to the left, gravity acts vertically downward on the horizontal holding means 40 so that the inner frame 20 rotates rearward (B direction) and the seat portion 30 is tilted backwards. The sheet portion 30 is rotated and tilted to the right (R direction) so that the sheet portion 30 is horizontally maintained (see FIGS. 2 and 4).

When the bottom of the hull is inclined forward and tilts to the right, gravity acts vertically downward on the horizontal holding means 40 so that the inner frame 20 rotates backward (B direction), and the seat portion 30 is tilted backward. The sheet portion 30 is rotated and inclined to the left side (L direction) so that the sheet portion 30 is kept horizontal (see FIGS. 2 and 5).

When the bottom of the hull is also tilted to the left while tilting backwards, gravity acts vertically downward on the horizontal holding means 40 so that the inner frame 20 is rotated forward (F direction) and the seat portion 30 is tilted forward. The sheet portion 30 is rotated and tilted to the right (R direction) so that the sheet portion 30 is horizontally maintained (see FIGS. 3 and 4).

When the bottom of the hull is inclined backwards and also to the right, gravity acts vertically downward on the horizontal holding means 40 so that the inner frame 20 rotates forward (F direction) and the seat portion 30 is tilted forward. The sheet portion 30 is rotated and tilted to the left side (L direction) so that the sheet portion 30 is horizontally maintained (see FIGS. 3 and 5).

As described above, gravity acts vertically downward on the horizontal holding means 40 so that the inner frame 20 and the seat portion 30 move in a direction opposite to the swinging direction of the hull to keep the seat portion 30 horizontal. .

Fig. 9 is an embodiment of the present invention. 2 is a view showing the state of the ship chair having a horizontal holding structure according to the present invention when the ship is inclined to the left and the bottom of the hull is inclined to the left, FIG. Becomes vessel is tilted to the right in a second embodiment of the present invention it shows a state of the vessel chair having a gimbal structure according to the present invention in the case that becomes the bottom of the hull tilting to the right.

Embodiment 2 of the present invention is identical in configuration to that of Embodiment 1 except for the horizontal holding means 40.

As shown in Figure 6, the horizontal holding means 40 of the second embodiment of the present invention is composed of a pyramidal pyramidal weight 41 as in the first embodiment is provided in the lower portion of the seat portion 30, In the lower portion of the inverted pyramid-shaped weight 41 may be further provided with a square columnar weight (42).

When the horizontal holding means 40 is composed of only the inverted pyramidal weight (41), a magnet is attached to the lower surface of the inverted pyramidal weight (41), which is referred to as the upper magnet (M). When the horizontal column 40 is also provided with a rectangular columnar weight (42), the magnet is attached to the lower surface of the rectangular columnar weight (42), which is referred to as the upper magnet (M).

A support plate 90 is provided at the bottom of the hull bottom of the seat part 30, and the support plate 90 is formed in a parabola shape so that the seat part 30 according to the front and rear rotation of the inner frame 20. It has a parabolic surface corresponding to the circumferential surface which is drawn while the upper and rear magnets M move while tilting forward and backward and left and right rotation of the seat part 30.

The front, rear, and left and right ends of the upper surface of the support plate 90 are provided with magnets, respectively, and the lower magnets (A: magnets provided at the front end, B: magnets provided at the rear end, C: provided at the left end). Magnet, D: magnet provided at the right end).

The magnets have an N pole and an S pole, and the same poles have a pushing force and the other poles have a drag force. In the second embodiment, the bottom magnets A, B, C, and D attract the top magnets M. It pulls.

An upper part that moves when the front and rear sides of the seat part 30 are inclined and the left and right sides of the seat part 30 are rotated according to the front and rear rotation of the inner frame 20 among the lower magnets A, B, C, and D. The lower magnets A, B, C, and D, which are located closest to the magnet M, attract the upper magnet M, so that the weight of the horizontal holding means 40 provided in the lower portion of the seat portion 30 is reduced. The center should be easily operated vertically downward.

When the diameter of the support plate 90 is narrower than the width of the seat 30, the lower magnets (A, B, C, D) attached to the front, rear and left and right ends of the upper surface of the support plate 90 is too attached The force of gravity pulls the upper magnet M before the center of gravity of the horizontal holding means 40 reaches vertically downwards, rather it prevents the center of gravity of the horizontal holding means 40 reaching vertically downwards. Since the diameter of the support plate 90 may be formed not narrower than the width of the sheet portion 30.

The upper magnet (M) and the lower magnets (A, B, C, D) is provided as a permanent magnet having a long-term magnetism, it is preferable to provide a neodymium (neodymium) magnet having the strongest magnetic force among the magnets.

Hereinafter, the operation and effects of the ship chair having a horizontal maintenance structure according to the second embodiment.
