According to the elevator apparatus for view described in claim 1,
An elevating passage through which the see-through cage ascends and descends is recessed in the outer wall surface of the building and extends in the up-down direction, and has a blow-through structure without a ceiling portion.

A guide member is vertically extended on the inner wall surface of the hoistway. One end of a support member is slidably attached to the guide member, and a see-through cage is supported at the other end in a cantilever state. That is, when looking at the hoistway from the outside of the building,
Only the guide member is visible, and the wires and the counterweight connected to the ceiling portion of the see-through cage are invisible like the conventional elevator apparatus, so that the appearance of the entire building is improved. Further, since it is not necessary to suspend the see-through cage with a wire, there is no power chamber in the upper part of the ascending / descending passage, and the occupant riding on the see-through cage does not feel pressure from above. Further, since there is no hanging structure on the upper part of the cage, the degree of freedom in designing the cage is increased and the aesthetic appearance is improved. In the elevator apparatus for view according to claim 2,

By rotating the drive reel and winding up and rewinding the wire, the cage moves up and down along the guide member. However, the wire and the counterweight are hidden by the guide member and cannot be seen from the outside. Since it is only exposed, it does not spoil the aesthetics of the hoistway.

In the elevator for observation according to the third aspect of the invention, the screw shaft extends vertically in a wall surface at the back of the hoistway. A receiving member whose one end supports a raising / lowering cage is screwed onto the screw shaft. Therefore, when the screw shaft is rotated in the normal and reverse directions, the receiving member moves up and down along with the cage along with the cage. Therefore, since only the screw shaft is exposed in the hoistway, the appearance of the building is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows a building 10 equipped with an elevator for outlook according to the first embodiment. On an outer wall 10A of the building 10, an up-and-down passage 12 having a blow-through structure, which is recessed in a U shape inside the building 10, is formed in the up-down direction. The up-and-down passage 12 is divided by a partition wall 14 extending in the vertical direction, and two see-through cages 16 are arranged so as to be able to move up and down.

The side surface and the ceiling surface of the see-through cage 16 are formed of tempered glass, and the field of view of an occupant riding in the see-through cage 16 is widened in the horizontal and vertical directions. This vertical field of view is for the hoistway 12
Has a blow-through structure and does not have a power chamber for covering the upper portion unlike the conventional case, and thus is greatly enlarged. Further, since the hoistway 12 is a separate section from the building 10, smoke generated by a fire or the like does not flow into the hoistway 12 and can be used as a blame passage. As a safety measure, an entrance protection fence F is attached to the lower part of the hoistway 12 so that no one can enter the hoistway 12.

As shown in FIGS. 2 and 3, the hoistway 12
The wall surface on the back side is concave, and a guide rail 18 made of H-shaped steel extends vertically. In the opening of this recessed portion, a shielding portion 23 extends so as to conceal both widthwise ends of the guide rail 18.

As shown in FIG. 4, a box-shaped moving member 20 having a slit 20A formed in the length direction at a portion corresponding to the web 18A is slidably inserted into the guide rail 18. A roller 22 is rotatably attached to the inside of the moving member 20 so as to sandwich the front flange 18B of the guide rail 18 from both sides.

Further, a base end portion of a cantilevered arm 40 protruding into the hoistway 12 is fixed to the moving member 20. A lift table 42 is stretched over the arm 40, and the see-through cage 16 is placed on the lift table 42.
Is installed.

On the other hand, one end of a wire 24 is connected to the back surface of the moving member 20. This wire 24 is shown in FIG.
As shown in FIG. 5, the guide rail 18 is concealed by the flange 18B (see FIG. 4). Also, wire 2
The other end of 4 is connected to the counterweight 26, and the intermediate part is wound around the drive reel 28 as shown in FIG. The drive reel 28 is rotated by a drive motor 30 to wind and rewind the wire 24. This allows the see-through cage 16 to be guided by the guide rails 18.
The inside of the ascending / descending passage 12 is moved up and down.

These drive reel 28 and drive motor 30
The power chamber 32 in which the
That is, the building 1
Since it is arranged inside 0, see-through cage 16
It does not block the vertical view of the occupants inside.

As shown in FIG. 3, the see-through cage 16
A door 34 is attached to the back side of the so as to be openable and closable. A boarding passage 36 extending between the guide rails 18 is provided on each floor so that the door 34 can be accessed. A shutter-type door 38 is provided at an opening 36A of the boarding passage 36 to shield the elevator passage 12 from the elevator passage 12. This door 38 may be a normal horizontal sliding door type instead of the shutter type if the frontage dimension can be sufficiently taken.

Next, the operation of the elevator for outlook according to this embodiment will be described. The operation system of the elevator for observation is the same as that of a general elevator, and an operation panel is provided in the see-through cage 16 and a boarding passage 36.
Is equipped with a call button. These operation panel and call button are connected to the control device, and when these signals are input to the control device, the drive motor 30 rotates the drive reel 28 to move the see-through cage 16 to the call floor or destination designated floor. It is designed to be moved. When the see-through cage 16 arrives at the calling floor, the door opening / closing device is driven to open / close the doors 34 and 38 so that the passenger can get on and off the boarding passage 36.

Further, since the power chamber 32 does not block the upper portion of the ascending / descending passage 12, the occupant riding on the see-through cage 16 can feel a sense of openness. In addition, see-through cage 16
The counterweight 26 also moves up and down in accordance with the elevation of the building 10. Since the counterweight 26 and the wire 24 are hidden by the guide rails 18, the appearance of the building 10 when viewed from the outside is improved.

Further, since the up-and-down passage 12 is open, smoke generated by a fire or the like does not stay in the up-and-down passage 12 and can be used as a blame passage. Further, it is possible to prevent a fire from spreading because the hoistway 12 becomes a flue (chimney).

Further, since the hoistway 12 thus installed outdoors is not regarded as a vertical hole section according to the Building Standards Law, there is no restriction on fire protection and it is possible to design freely.

The elevating passage 12 does not necessarily have to be provided with a concave outer wall surface, but a slit for a rail may be formed on the outer wall surface and a cage may be supported by a supporting member protruding from this slit. . Further, it is not always necessary to provide the partition wall 14 as shown in FIG. 1, and the partition wall 14 may be made of a transparent member.

Next, the second embodiment will be described. Figure 5
As shown in FIG. 6 and FIG. 6, in the elevator for outlook of the second embodiment, the door 50 for getting on the see-through cage 16 is arranged on the side, and the door 52 correspondingly corresponds to the hoistway. It is arranged on 12 facing wall surfaces.

Therefore, as in the first embodiment, the boarding passage 3
It is not necessary to provide 6 (see FIG. 3), and the see-through cage 16 can be directly boarded from the floor.

If the pry bar on the side of the building 10 is protected, the occupants of the building 10 and the see-through cage 16 can be constructed by making the rear surface of the hoistway 12 glass.
The occupant's field of view can be further expanded.

Next, a third embodiment will be described. Third
In the embodiment, as shown in FIG. 7 and FIG.
The wall surface on the back side is recessed, and a screw shaft 56 extends vertically in the recess 12A. A tubular body 58 whose inner peripheral surface is threaded is screwed into the screw shaft 56. This tube 58 has H
One end of the shape steel 60 is fixed, and the other end projects into the up-and-down passage 12. On top of this H-shaped steel 60, H-shaped steel 62
Are assembled in a cross girder pattern, and the lift table 42 is placed on the table.

In this elevator system for observation, the see-through cage 16 is moved up and down together with the tubular body 58 by rotating the screw shaft 56 in the forward and reverse directions by a turning motor provided below.

As described above, in the third embodiment, the counterweight and the wires are not required, and the structure is simplified, so that the mounting cost of the elevator apparatus can be reduced.
