Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an elevator car for observation, in which a part of the peripheral wall of the car is made of window glass for the purpose of providing a view from the inside of the elevator car.

[Conventional technology]

A general elevator car that is not for observation has a box-like shape consisting of a peripheral wall that covers the side surfaces, a ceiling plate, and a floor. On the other hand, part of the elevator car is exposed to the outside of the building, and a glass window installed in this exposed part allows passengers to see the scenery outside It is on the side window.

An example of a conventional elevator car for viewing will be described with reference to FIGS. 5 to 7. FIG. 5 is a perspective view showing the entire view elevator car. Although not shown in FIG. 5, the strength of the car is determined by the lower window peripheral wall supporting the lower part of the glass window and the upper window peripheral wall supporting the upper part of the window.
It is maintained by a structure consisting of the side peripheral wall and the rear peripheral wall existing in the non-exposed portion, and a floor and a ceiling plate continuous to these peripheral wall portions. The exterior plate 1 that covers the outer periphery of the upper side of the ceiling plate is for covering the elevator machinery in a good appearance. An intermediate upper exterior plate 2 as a design plate is provided on the outer periphery of the window upper peripheral wall existing under the ceiling plate. Below this middle upper exterior plate 2, there are several columns 3, and below the columns,
There is an intermediate exterior plate 4 that covers the outer periphery of the lower peripheral wall of the window (not shown), and below that, an exterior plate 5 for clearly covering the elevator machinery arranged below the floor (not shown). The ceiling plate, the intermediate exterior plate, and the like in the exposed portion of the car are supported by the columns.

FIG. 6 is a detailed view of the VI-VI cross section of FIG. 5, showing a conventional fixing structure for the window glass 6. An end surface of the window glass 6 is in contact with the column 3 via a cushioning material 7, and a contact portion is sealed by an elastic seal 8. Further, the presser foot in the thickness direction of the window glass 6 is formed by a glass presser 9, and the glass presser 9 is attached to the column 3 by a screw 10. In such a structure, the view of passengers was obstructed at the portion b near the pillar. FIG. 7 is a sectional plan view of FIG. 5, showing a state where the elevator car is exposed to the outside of the building 11.

[Problems to be solved by the invention]

As described above, in the conventional technique, the pillar 3 is provided in the window glass joint,
Since the pillars 3 support the ceiling plate and intermediate exterior plates of the car and fix the window glass, the pillars obstruct the view of passengers from inside the car, narrowing the field of view as well as the entire observation elevator. There was a problem that there was a restriction on the design.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to provide an elevator car for viewing with a wide field of view and excellent design.

[Means for solving problems]

The present invention relates to an elevator having a strength composed of a lower window peripheral wall supporting a lower portion of a glass-covered window and an upper window peripheral wall supporting the upper window, side peripheral walls and a rear peripheral wall of an unexposed portion, a floor and a ceiling plate. The support structure is formed in a car, and a frame body is provided on the side peripheral wall and the ceiling plate in the unexposed portion to form a U-shaped support structure composed of each frame body. The weight of the exposed portion is supported by abutting the protruding portion from the upper part of the body toward the exposed portion of the ceiling plate.

[Action]

It is possible to strengthen each by providing a frame body to the side peripheral wall existing in the non-exposed portion and the ceiling plate existing in the non-exposed portion. By supporting the protruding member from the upper part of the overall U-shaped support structure composed of each frame toward the exposed part of the ceiling plate, the weight of the exposed ceiling plate and intermediate upper exterior plate can be supported. it can.

〔Example〕

(First Embodiment) A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a side view of the observation elevator car, showing the inside of the car by partially cross-sectioning it.
FIG. 2 is a detailed view of section II-II in FIG. FIG. 3 is a perspective view showing only the support structure of FIG. First
In FIG. 2 and FIG. 2, the side peripheral wall 22 and the window lower peripheral wall 23 are fixed to the floor 21 of the car by bolts (not shown).
An intermediate corner exterior plate 24 is fixed to the outer periphery of the side peripheral wall 22 with screws 25. An intermediate lower exterior plate 4, which is a design plate, is fixed to the lower window peripheral wall 23 with screws. A window upper peripheral wall 26 is fixed to the upper portion of the side peripheral wall 22 by bolts and is projected.

Next, a ceiling plate 28 that suspends the ceiling 27 is carried in to the upper portions of these peripheral walls 22 and 26, and is fixed to the side peripheral wall 22 and the window upper peripheral wall 26 by bolts all around, and is a design plate for the window upper peripheral wall 26 and the ceiling plate 28. The intermediate upper exterior plate 2 is fixed with screws. Although not shown in FIG. 1, there is a rear peripheral wall continuous with the side peripheral wall on the rear side of the car.

In the assembled state up to this point, the exposed window upper peripheral wall 26, the intermediate upper exterior plate 2, and the ceiling 2 are exposed from the side peripheral wall 22 to the window side.
7. Since part of the ceiling plate 28 is in an unsupported overhang state, the weight of this exposed portion causes the window glass fixing portion at the tip of the window upper peripheral wall to hang down.

Therefore, in order to support the weight of the exposed portion, a supporting structure as shown in FIG. 3 is constructed. That is, the side peripheral wall 22 existing in the unexposed portion is reinforced by the frame body formed by the four members 31, 32, 33, 34. This frame is provided in contact with the outer surfaces of the left and right side peripheral walls. A frame body is also provided by the members 34, 35, 36 on the ceiling plate 28 existing in the unexposed portion. All of these members are bolted together to form a U-shaped support structure as a whole.

This support structure supports a cantilever beam 37 which is a projecting member. That is, the support beam 37 is projected from the upper portion of the support structure toward the exposed portion of the ceiling plate 28.
The tip end of the ceiling beam 28 is horizontally fixed by a bolt at the tip end of the support beam 37 that is abutted. The cantilever 37 prevents the window glass fixing portion from hanging down.

Next, the cushioning material 7 is attached to the edges of the window lower peripheral wall 23 and the side peripheral wall 22 that form the window frame, the window glass 6 is inserted, and the window lower peripheral wall 2
3, the window glass retainer 38 is attached to the side peripheral wall 22 and the window upper peripheral wall 26, and the entire periphery of the edge of the window frame is fixed with screws. Then, the window glass 6 is set so as to be positioned at the center of the groove portion, and the window glass 6 is set.
The dimension d between the window glass 6 and the window glass 6 is set to about 10 mm, and the elastic sealing material 8 is inserted all around the gap between the window glass 6 and the window glass retainer 38 and the exterior plates 2 and 4. Finally, the elastic sealing material 8 is inserted into the gap d between the window glasses 6 adjacent to each other in the longitudinal direction between the window glasses 6 (FIG. 2) to complete the assembly.

According to this embodiment, the seam portion of the window glass 6 is only joined by the elastic sealing material 8 of about 10 mm, and the sagging of the window upper peripheral wall 26 of the window glass 6 is supported by the strong support structure. It is prevented by the cantilever 37. Further, since an appropriate gap is always maintained between the upper portion of the window glass 6 and the window upper peripheral wall 26, a safe and wide field of view can be secured without directly applying a load to the window glass 6.

(Second Embodiment) Another embodiment will be described with reference to FIG.

FIG. 4 is a view of the elevator car for observation as seen from the side, similar to FIG. 1, and shows the inside of the car by partially cross-sectioning it. In this embodiment, instead of the cantilever beam 37 shown in FIG. 1 of the first embodiment, a structure composed of three kinds of members is adopted as the projecting member. That is, the L-shaped hanging metal fitting 41 is firmly mounted on the frame body provided on the ceiling plate.
From the tip of the hanging bracket 41, the hanging rod 42 is a ceiling plate.
It is arranged toward the tip of 28. A reinforcing member 43 is arranged on the upper surface of the ceiling plate 28, and the suspension rod 42 is pin-connected to the reinforcing member 43. The other end of the suspension rod 42 is also pin-connected to the suspension fitting 41. The two pin connections are made by the lock nut 44. By using the lock nut 44, the length of the suspension rod between the two pin connections can be adjusted by relatively rotating the suspension rod 42 about its axis.

According to this embodiment, in addition to the same effects as those described above,
By tightening the lock nut 44 to the hanging rod portion, the tip window glass fixing portion can be moved up and down for horizontal adjustment, and there is an effect that a safer and easier adjustment operation can be performed.

〔The invention's effect〕

According to the present invention, the supporting structure is formed on the side peripheral wall and the rear peripheral wall of the unexposed portion, that is, the invisible portion, of the elevator elevator car for viewing, and the projecting member that abuts from this supporting structure. Therefore, the weight of the exposed portion of the ceiling plate can be supported. Therefore, it is possible to eliminate the pillars as in the past, so that it is possible to widen the field of view of passengers and to improve the work efficiency of elevator car assembly work by eliminating the pillars of complicated structure. Therefore, it is possible to provide an elevator car for prospects that is inexpensive and has an excellent design.
