Description

  The present invention relates to an open stair apparatus that combines an open stair and an elevator.

  Conventionally, the thing of patent document 1 is proposed as a stairway device which combined the staircase and the elevator. The stair device of patent document 1 has a hoistway which comprises an elevator, and the surrounding staircase provided along the outer periphery of this hoistway.

  On the other hand, as a kind of staircase for raising and lowering between the lower floor and the upper floor in a building, an open staircase in which a footboard is separated from a wall panel is known. It is installed between the first floor and the second floor (see, for example, Patent Document 2).

JP 11-343714 A Japanese Patent No. 3732846

  However, the stairway device of Patent Document 1 is a combination of a normal staircase in which a footboard is fixed to a wall panel and an elevator, and cannot combine an open staircase and an elevator.

  Moreover, although the stairway device of patent document 1 is provided with the surrounding staircase along the outer periphery of an elevator, the elevator and the surrounding staircase are not firmly fixed, Therefore, the point of whole structure strength and stability It was insufficient.

  Furthermore, since the stairway device of patent document 1 requires the floor surface for entrances and exits of a staircase and the floor surface for elevators on the second floor separately on the second floor, the floor surface for entrances and exits of the staircase and elevator floors on the second floor are required. The total area with the lobby floor could not be reduced. The elevator getting-on / off lobby is a waiting space for getting on and off the elevator.

  The present invention has been made in view of the above-described circumstances, and an open staircase and an elevator can be combined, and the overall structural strength and stability can be sufficiently increased. It is an object of the present invention to provide an open stairway device that can reduce the total area of the floor surface for the entrance and exit and the floor surface for the elevator entrance / exit.

In order to achieve the above object, the present invention provides an open staircase, an elevator in which a hoisting car is disposed in the hoistway of a structure having a hoistway formed therein, and a floor on the second floor of a house. And a landing that is connected to the surface,
The lower end of the open staircase is fixed to the floor of the first floor of the house, the upper end is fixed to the front end of the landing, and the elevator is disposed behind the landing, and the landing on the structure An open stairway device is provided in which the rear end portion is fixed and the floor of the landing is a lobby for getting on and off the elevator on the second floor.

  The open stairway device of the present invention has an open staircase by installing a landing on the second floor of a house, fixing the lower end of the open staircase to the floor of the first floor of the house, and fixing the upper end to the front end of the landing hall. And elevators can be combined. Moreover, the overall structural strength and stability can be sufficiently increased by fixing the landing area having a large area to the elevator structure. In addition, since the floor of the landing on the second floor is shared as the floor for the entrance and exit of the stairs and the floor for the elevator entrance / exit lobby, the sum of the floor for the entrance and exit of the stairs and the floor of the elevator entrance / exit lobby The area can be reduced, and space can be saved.

  The open stairway device of the present invention can combine an open staircase and an elevator, and can sufficiently increase the overall structural strength and stability. It is possible to save space by reducing the total area of the floor for the entrance and exit lobby.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following examples. 1 to 4 show an embodiment of an open stair apparatus according to the present invention. FIG. 1 is a second floor plan view, FIG. 2 is a first floor plan view, FIG. 3 is a front view, and FIG. FIG.

  The open staircase device 10 of this example includes a straight type open staircase 12, an elevator 14, and a landing 16. A straight-type open staircase is a staircase where the entire staircase is rectangular when viewed from above, and all treads are parallel.

  In the open staircase 12, a plurality of treads 20 are fixed to a pair of parallel girder bodies 18 by attachment members 22. The attachment member 22 may have any configuration as long as the tread plate 20 can be attached to the girder body 18. The lower end of the girder body 18 of the open staircase 12 is fixed to the floor surface 1FL of the first floor of the house by appropriate fittings such as bolts and nuts, and the upper end is bolted to the lower surface of the front end portion of the landing base 34 described later of the landing 16. It is fixed by an appropriate fixture such as a nut. Moreover, the open staircase 12 is arrange | positioned along the wall W at the width direction one end side, and the handrail 26 (refer FIG. 1) is attached to the width direction other end side. In the open staircase 12, the girder body 18 and the mounting member 22 are formed of an aluminum alloy, and the tread board 20 is formed of a wooden board material. However, the materials of these members are not limited.

  The elevator 14 is a so-called home elevator, and a lifting car 32 is disposed in the lifting / lowering path 28 of a substantially rectangular tubular structure 30 having a lifting / lowering path 28 formed therein. The elevator 14 is disposed behind the landing 16, and the rear end of the landing 16 is fixed to the structure 30 by appropriate fixtures such as bolts and nuts. There is no limitation on the lifting mechanism of the elevator 14, and a suitable mechanism such as a rope type that raises and lowers the lifting car 32 using a wire rope as a main rope and a hydraulic type that lifts and lowers the lifting car 32 using a hydraulic jack can be adopted. In the elevator 14, the main body of the structure 30 and the elevator car 28 are formed of an aluminum alloy, and the open / close door of the structure 36 is formed by mounting an acrylic resin plate in a frame made of an aluminum alloy. The material of the member is not limited.

  The landing 16 includes a landing base 34 in which a beam portion is formed inside a square frame, and a landing base plate 36 fixed to the upper surface of the landing base 34. The landing 16 is installed such that its floor is continuous with the floor 2FL on the second floor of the house. Further, the landing base 34 of the landing 16 is fixed to the structure 30 of the elevator 14 by appropriate fixtures such as bolts and nuts. On the second floor, the floor of the landing 16 is used as an elevator lobby for the elevator 14. In the landing 16, the landing base 34 is formed of an aluminum alloy and the landing plate 36 is formed of a wooden board, but the material of these members is not limited.

  In addition, this invention is not limited to embodiment mentioned above, A various change is possible. For example, in this example, a straight-type open staircase is used. However, as shown in FIG. 5A, when viewed from above, an open staircase in which the three steps of the staircase 40 at the top of the staircase turn around is a staircase. (Three-stage type), as shown in FIG. 5 (b), an open staircase with a landing (L-shaped) in which the lower staircase member 44 and the upper staircase member 46 form a right angle at the landing 42 when viewed from above. Mold type), open staircase with landing structure (U-shaped type, not shown) and other structures open so that the orientation of the lower and upper members is reversed in the landing when viewed from above Stairs may be used.

It is a 2nd floor top view which shows one Embodiment of the open stair apparatus which concerns on this invention. It is a 1st floor top view of the open stairway device of FIG. It is a front view of the open stair apparatus of FIG. It is a side view of the open stairway device of FIG. It is explanatory drawing which shows an example of an open staircase.
