Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention allows a single-family home for housing to be rotated according to preference, and enables adjustment of daily sunshine hours and summer and winter sunshine hours. , Revolving houses that can change the living environment by making it possible to enjoy changes in the landscape at the same time.

<Prior Art> Conventionally, there is a rotary house as shown in FIG. 5 (JP-A-57-104738). A house 1 of this rotary house is constructed on a rotary bottom plate 2, and drive wheels 3a and idle wheels 3b for rotating the rotary bottom plate 2 are provided near the outer peripheral portion of the rotary bottom plate 2. A plurality of wheels 3 composed of the drive wheels 3a and the idle wheels 3b roll on an annular rail 4 provided on the fixed ground 5. Then, as the wheels 3 roll, the house 1 built on the rotary bottom plate 2 rotates.

<Problems to be Solved by the Invention> However, in the conventional rotary house, the annular rail 4 provided on the fixed ground 5 is provided below the rotary bottom plate 2 on which the house 1 is constructed. Since the wheels 3 are adapted to roll, the house 1 is only mounted on the annular rail 4 and is not fixed to the ground 5. That is, the importance of rotating the house 1 is so great that the stability and safety of the house 1 are not paid so much attention. Therefore, it is completely defenseless against typhoons and earthquakes,
There is a big problem that people cannot live their lives with peace of mind.

A plurality of drive wheels 3a and idle wheels 3b are attached to the outer periphery of the rotating bottom plate 2, that is, the outer periphery of the house 1, and the wheels 3 attached to the outer periphery support the weight of the house 1.
It is necessary to attach several tens of wheels 3 and there is a problem that the structure becomes complicated. Further, if the number is reduced, the diameter of the wheel 3 must be increased.

Furthermore, if the drive wheels 3a are electrically rotated to accurately stop the house 1 at a required position, the drive system becomes a complicated mechanism.

Therefore, an object of the present invention is to provide a rotary house in which a house can be freely rotated by a mechanism and the house can be always fixed in a stable state.

<Means for Solving Problems> In order to achieve the above object, the rotary house of the present invention is mounted on the bottom surface of a house and rotates one raceway ring having a raceway groove and the one raceway wheel. A plurality of teeth formed along the one bearing ring, and the other bearing ring fixed to the foundation and having a bearing groove, the bearing groove of the one bearing ring and the other bearing ring. It is characterized in that it comprises a rolling element interposed between the raceway groove and the raceway groove, and the two races are not separated from each other in the radial direction and the axial direction via the rolling element.

<Operation> When rotating a house, a rotational force is applied from the outside through a plurality of teeth formed along one orbital ring attached to the bottom surface of the house. Then, the one bearing ring is supported by the rolling elements and rotates around the other bearing ring fixed to the foundation, and the house is rotated accordingly. Therefore, the house is rotated by a very simple mechanism. In addition, at that time, one bearing ring attached to the bottom of the house and the other bearing ring fixed to the foundation are not separated by the rolling element interposed between the bearing grooves of both bearing rings. Since the house is fixed to the foundation via both bearing rings and rolling elements, the house is always fixed in a stable state by a simple mechanism and can be rotated and stopped.

<Example> Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an elevational view of the entire house, and the house 10 has a square two-story wooden structure in front. Under the floor in the center of the house 10, a keyhole-shaped underfloor hole 16 consisting of a circular underfloor hole 16a and a subsequent rectangular underfloor hole 16b for concentrating water supply / drainage and electric wiring is dug and surrounded by a concrete foundation 12. I'm out. In order to keep the house 10 horizontal on the circular portion of the foundation concrete 12, a leveling mortar foundation 13 is laid, and as will be described later in detail on the horizontal surface of the leveling mortar foundation 13, with super-sized external teeth. Swivel bearing 1
While the inner ring 21 of No. 1 is fixed, the outer ring 2 is attached to the swivel seat bearing 11.

That is, the entire house 10 is in a state of resting only on the foundation concrete 12 while maintaining the level through the swivel bearing 11. (Outer peripheral steel beam 1 on the outer periphery of the house 10
4c maintains an appropriate clearance with the outer peripheral concrete 30. The swivel bearing 11, as shown in FIG. 3, has an outer ring 20 having outer teeth 29 on its outer peripheral surface, balls 22 as rolling elements, and an inner ring 21. The inner ring raceway surface 32 is provided on the outer circumferential surface of the inner ring 21, while the outer ring raceway surface 31 is provided on the inner circumferential surface of the outer ring 20, and the inner ring raceway surface 32 and the outer ring raceway surface are provided when the outer ring 20 is arranged outside the inner ring 21. A plurality of balls 22 are arranged in a space formed by 31. That is, the outer ring 20 and the inner ring 21 assembled as described above are configured to be vertically and horizontally non-separable via the balls 22. And the outer ring 20
Is supported by the balls 22 and can smoothly rotate around the inner ring 21, and the balls 22 can receive the thrust load applied to the outer ring 20 or the inner ring 21.

The diameter of the swivel bearing 11 is determined so that the house 10 satisfies the following conditions.

(1) The house 10 is stable so as not to tilt.

(2) The floor of the house 10 should not bend due to its weight.

(3) The bearing itself is equipped with a load capacity sufficient to receive the weight of the house 10.

In a practical example, the diameter of the swivel bearing 11 is 1 of the house 10.
It is set to about 1/2 of the side length. By doing so, the above conditions can be satisfied, and the load applied to the floor can be applied almost uniformly, so that the floor structure can be simplified.

A worm speed reducer 18 directly connected to the motor 17 is installed in the square floor under hole 16b of the under floor hole 16, and a small gear 19 that meshes with the external teeth 29 of the slewing bearing 11 is installed on the output shaft of the worm speed reducer 18. It is attached. The motor 17 is electrically wired so that it can be operated from one room of the house 10, and the rotation angle of the house 10 can also be set.

2 and 3 are views showing the mounting state of the slewing bearing 11. On the circular portion of the foundation concrete 12, a leveling mortar foundation 13 for adjusting the horizontal level is laid. 27 is an anchor bolt, this basic concrete 1
2 and embedded and fixed in the foundation 13 of mortar. Then, the anchor bolt 27 is installed through the bolt hole 26 of the inner ring 21 of the slewing bearing 11, and the inner ring 21 is firmly fixed to the foundation 13 of the leveling mortar with the nut 28.

FIG. 4 is a plan view showing the structure of the reinforcing steel beam 14 to which the outer ring 20 of the swivel bearing 11 is attached. A main reinforcing steel beam 14a, a sub-reinforcing steel beam 14b, and a peripheral steel beam 14c, which are the reinforcing steel beams 14, are arranged on the outer ring 20 as shown in the figure. Then, in the bolt hole 24 formed in the outer ring 20, the bolt hole 3 of the main reinforcing steel beam 14a and the auxiliary reinforcing steel beam 14b is formed.
4 and put the hexagon bolts 25 into these bolt holes 24 and 34.
Through the main and auxiliary reinforcing steel beams 14a and 14b and the outer ring 20.
Are securely fixed with nuts 35 as shown in FIG. Further, a floor is made on the main and auxiliary reinforcing steel beams 14a and 14c and the outer peripheral steel beam 14c as shown in FIG. 1 to construct a normal house 10.

An oil seal 23 is attached inside the lower end surface of the outer ring 20 so that the lip contacts one end surface of the inner ring 21. Similarly, an oil seal 23 is also attached to the outside of the upper end surface of the inner ring 21 so that the lip contacts one end surface of the outer ring 20. Therefore, the slewing bearing 11 as a whole has a sealed structure, and it is possible to prevent rusting of the balls 22 of the slewing bearing 11, the outer raceway surfaces 31 and 32 of the inner rings, and the intrusion of foreign matter into the raceway surfaces 31 and 32. Further, although the inside of the slewing bearing 11 is filled with grease, a plurality of greasing holes 33a are formed on the inner diameter surface of the inner ring 21 for replenishment, and grease is replenished from the greasing holes 33a. It is like this. The greasing hole 33a is usually plugged with a plug 33b.

When the resident sets the rotation angle according to his / her preference and turns on the switch of the motor 17, the worm speed reducer 18 starts to rotate with the rotation of the motor 17, and the small size of the worm speed reducer 18 is reduced. External tooth 2 meshing with gear 19
The slewing bearing 11 having 9 also starts to rotate at a slow speed of about 1/20 to 1/30 rpm, and the house 10 can be accurately rotated to the set rotation angle. 1/20 ~ 1/30 above
The rotation speed of rpm can be calculated and set by the reduction ratio of the worm speed reducer 18 and the gear ratio of the small gear 19 and the external teeth 29, and is set to a rotation speed that does not cause discomfort to the inhabitants by rotation. It is set.

In this manner, the floor of the house 10 is fixed to the outer ring 20 of the slewing bearing 11 by the plurality of bolts 25 via the reinforcing steel beam 14, and the inner ring 21 that is not separated from the outer ring 20 is fixed to the basic concrete 12 and the flat ring. Since the plurality of anchor bolts 27 embedded in the foundation 13 of the mortar are fixed by the nuts 28 through the anchor bolts 27, the house 10 is slewed by the non-separated slewing bearing 11, and the ground foundation concrete 1
It is securely fixed to 2 and can maintain a very stable state against typhoons and earthquakes.

Further, since the large slewing bearing 11 having a diameter that is approximately half the length of one side of the house is used, the balance of the house 10 is maintained, and the house 10 tilts even during rotation,
It can rotate quietly without shaking.

The house 10 is rotated by the worm reducer 18 having the small gear 19 and the external teeth 29 meshing with the small gear 19 of the worm reducer 18, so that the structure is 1/20 to 1/30 with a simple mechanism.
It is possible to obtain a slow rotation of about rpm and accurately control the rotation.
Therefore, it becomes possible to enjoy the changes in the environment without making the occupants feel uncomfortable.

In the above embodiment, the swivel bearing 11 is composed of the outer ring 20, the ball 22 and the inner ring 21, but the present invention is not limited to this, and the bearing ring fixed to the bottom surface of the house 10 and the foundation are Any bearing may be used as long as the fixed bearing ring and the rolling elements sandwiched between the two bearing rings are not separated. That is, for example, the inner ring may have a T-shaped cross section having an outward protruding portion, the outer ring may have a U-shaped cross section into which the above-mentioned protruding portion of the inner ring can be fitted, and the rollers may be arranged on the fitting surface.

Although the outer ring 20 is driven in the above embodiment, the house 10 may be fixed to the inner ring 21 by turning the outer ring 20 as a base, and the inner ring 21 may be provided with inner teeth to drive the inner ring 21. .

<Effects of the Invention> As is apparent from the above, the rotary house of the present invention has one raceway ring having a raceway groove attached to the bottom surface of the house,
The other race having a raceway groove fixed to the foundation and the rolling element interposed between the raceway grooves are provided, and the two raceways are configured to be inseparable from each other through the rolling body. Therefore, the house can be securely fixed to the foundation via both the bearing rings and the rolling elements, and the house can be freely and accurately rotated by the very simple mechanism.

Further, since a plurality of teeth are formed along the one bearing ring, the distance between the rolling element and the teeth is reduced so that a moment is not generated when the one bearing ring rotates, and the one bearing ring is It can rotate smoothly.
