Detailed Description
The following description of embodiments of the present invention is based on the accompanying drawings.
Examples
Fig. 1 is a plan view showing an assembled state of a car of an elevator according to an embodiment of the present invention.
The car is configured by arranging a plurality of side plates 2 on each of the left and right sides and the back side in the circumferential direction when viewed from the doorway 1 of the car, and joining them to each other. The side plates 2 can be arranged and connected to the platform 3. That is, a part of the side plates 2 is firmly joined and unitized by the work on the platform 3, and the units are configured to be connectable in consideration of the workability and strength on the platform 3 side.
Fig. 2 is a plan view showing an intermediate state of assembly of one L-shaped self-standing side panel unit in the car.
An L-shaped self-standing side plate unit 4 constituting the left side of the car is assembled to the platform 3 of the car. The L-shaped self-standing side panel unit 4 includes a plurality of side panels 2A, 2B, and 2C located on the left side as viewed from the doorway 1 and one connecting portion side panel 2D located on the back side, and is assembled into an L-shape having a corner portion 5. As will be described in detail later, a folded portion having a U-shaped cross section and folded back toward the back side is formed at an end portion of the coupling portion side plate 2D located on the side of the corner portion 5.
Since each of the side plates used in the L-shaped self-standing side plate unit 4 can be operated by the platform 3, a connecting structure is adopted in which an operator can go around the back side of the connecting structure to firmly connect the side plates. Various connecting structures are adopted between the side plates, so that the assembling operation can be easily carried out. As shown in the figure, the assembled L-shaped self-standing side panel unit 4 is rotated in the arrow direction, and is fixed with the corner 5 being disposed so as to correspond to the corner of the car itself.
Fig. 3 is a plan view showing an intermediate state of assembly of another L-shaped self-standing side panel unit in the car.
As in the case of the L-shaped self-standing side plate unit 4 described above, an L-shaped self-standing side plate unit 6 constituting the right side of the car is assembled to the car bottom 3. The L-shaped self-standing side plate unit 6 includes one connecting portion side plate 2F located on the back side and one side plate 2G, 2H, 2I located on the right side when viewed from the doorway 1, and is assembled into an L-shape having a corner portion 7. At the end of the coupling portion side plate 2F located at the corner portion 7, a folded portion having a U-shaped cross section and folded back to the rear side is formed, as will be described in detail later.
Since the assembly of the L-shaped self-standing side plate unit 6 is performed on the platform 3, the worker can perform the work not only from the inner surface side of each side plate but also around the outer surface side of each side plate, and the assembly work can be easily performed by adopting various connecting structures between the side plates. As shown in the figure, the assembled L-shaped self-standing side panel unit 6 is rotated in the arrow direction, and is fixed in such a manner that the corner 7 corresponds to the corner of the car itself.
Fig. 4 is a plan view showing a state before assembly of a rear intermediate side plate in an elevator car.
In the assembled state of the L-shaped self-standing side plate unit 4 and the L-shaped self-standing side plate unit 6, a space having a size of one side plate is formed between the coupling portion side plate 2D of the L-shaped self-standing side plate unit 4 and the coupling portion side plate 2F of the L-shaped self-standing side plate unit 6. The operation of arranging and connecting one intermediate side plate 2E in this space is also performed from the platform 3 side.
The present invention proposes a method for firmly fixing the intermediate portion side plate 2E between the coupling portion side plate 2D and the coupling portion side plate 2F from the car bottom 3 side in this state. Next, a detailed coupling structure and assembly of the intermediate portion side plate 2E will be described.
Fig. 5 and 6 are enlarged rear views showing a state before and a state after the coupling portion side plate 2F, the intermediate portion side plate 2E, and the coupling portion side plate 2D are coupled.
Fig. 5 and 6 are enlarged rear views, and therefore, the coupling portion side plate 2F, the intermediate portion side plate 2E, and the coupling portion side plate 2D are arranged in this order from left to right. Here, the coupling portion side plate 2F and the coupling portion side plate 2D are configured to be bilaterally symmetrical. In the enlarged rear views of fig. 5 and 6, the joint side plate 2F, the intermediate side plate 2E, the surface portions 2F1, 2E1, 2D1 of the joint side plate 2D, and the folded portions 2F3, 2E3F, 2E3D, 2D3 are visible.
Each of the coupling portion side plate 2F, the intermediate portion side plate 2E, and the coupling portion side plate 2D is formed of a plate material having a U-shaped end cross-sectional shape. Fig. 7 shows a cross-sectional structure of these side panels 2, where the side facing the doorway 1 is a face portion, the side at the back surface is a folded portion, and the portion connecting the face portion and the folded portion is a side portion, the face portion is 2F1, 2E1, 2D1, the folded portion is 2F3, 2E3F, 2E3D, 2D3, and the side portion is 2F2, 2E2F, 2E3D, 2D 3.
In fig. 7, one flat plate-like plate 9FE, 9DE is fixed to the coupling portion side plate 2F and the folded portions 2F3, 2D3 of the coupling portion side plate 2D in the height direction by using rivets, for example. The plates 9FE and 9DE fixed to the coupling portion side plate 2F and the coupling portion side plate 2D extend toward the intermediate portion side plate 2E, and have protrusions 11FE and 11DE at positions facing the folded portions 2E3F and 2E3D of the intermediate portion side plate 2E. On the other hand, the intermediate side plate 2E has engaging holes 13FE and 13DE at positions facing the protrusions 11FE and 11DE of the plates 9FE and 9DE in the folded portions 2E3F and 2E 3D.
As is apparent from the cross-sectional structure of fig. 7, when the intermediate-portion side plate 2E is fitted between the coupling-portion side plate 2F and the coupling-portion side plate 2D from the car bottom 3 side, the pressing position of the intermediate-portion side plate 2E is not at or above the surface alignment position by the plates 9FE, 9DE fixed to the folded-back portions 2F3, 2D3 of the coupling-portion side plate 2F and the coupling-portion side plate 2D, and the projections 11FE, 11DE formed on the plates 9FE, 9DE fixed in the height direction of the folded-back portions 2F3, 2D3 of the coupling-portion side plate 2F and the folded-back portions 2E3F, 2E3D of the intermediate-portion side plate 2E are engaged with the engagement holes 13FE, 13DE formed in the folded-back portions 2E3, 2E 3.
Fig. 5 shows a structure for realizing the fixing/engaging relationship of fig. 7. First, the plates 9FE and 9DE are fixed to the folded portions 2F3 and 2D3 of the coupling portion side plate 2F and the coupling portion side plate 2D so as to extend along the intermediate portion side plate 2E in the height direction. The fixation of the plates 9FE and 9DE is as follows.
Specifically, for example, as shown in fig. 5, a plurality of rivet holes are formed in advance in the folded-back portions 2F3, 2D3 of the coupling portion side plates 2D, 2F located at positions adjacent to the intermediate portion side plate 2E so as to be spaced apart from each other at predetermined intervals in the vertical direction. Further, a plurality of rivet holes 10FE and 10DE are formed in advance so as to be spaced apart from each other in the vertical direction at predetermined intervals also at height positions of the plates 9FE and 9DE corresponding to the plurality of rivet holes in the folded portions 2F3 and 2D3 of the coupling portion side plates 2D and 2F. When the plates 9FE and 9DE are fixed to the folded portions 2F3 and 2D3 of the coupling portion side plates 2D and 2F, the rivet holes 10FE and 10DE formed in the plates 9FE and 9DE and the rivet holes formed in the folded portions 2F3 and 2D3 of the coupling portion side plates 2D and 2F are aligned with each other, and the two are fixed by rivets inserted into the rivet holes. Although rivets are used for fixing the plates, the joining operation is performed in advance in the state shown in fig. 2 and 3, for example, and therefore the joining operation can be performed relatively easily.
In fig. 5, a plurality of headed pins 11FE and 11DE are fixed in advance to the half portions of the plates 9FE and 9DE on the side closer to the intermediate side plate 2E at a predetermined interval in the vertical direction. The headed pins 11FE and 11DE correspond to the projections 11FE and 11DE of fig. 7. Fig. 5 is a rear view, and therefore, the state of each of the headed pins 11FE, 11DE is not clear, but when the plates 9FE, 9DE are viewed from the inside of the car, as shown in fig. 7, each of the headed pins 11FE, 11DE is disposed with its head portion slightly extended toward the inside of the car.
The plates 9FE and 9DE are integrally plate-shaped structures that are not divided in the height direction. The height dimension is substantially the same as the same dimension of the coupling portion side plates 2F and 2D and the intermediate portion side plate 2E, and is a dimension in the entire height direction except for a portion shielded by the platform 3 and the ceiling when viewed from the car.
On the other hand, similarly, the folded portions 2E3F and 2E3D are formed on both sides of the middle portion side plate 2E in the width direction, and a plurality of holes 13FE and 13DE such as gourd holes are formed at predetermined intervals in the vertical direction of the folded portions 2E3F and 2E 3D. The long holes 13FE and 13DE are formed at positions corresponding to the headed pins 11FE and 11DE with a corresponding interval. The elongated holes 13FE and 13DE correspond to the engagement holes 13FE and 13DE in fig. 7.
therefore, when the intermediate side plate 2E is slightly raised and pushed in from the platform 3 side to between the coupling portion side plate 2F and the coupling portion side plate 2D as shown in fig. 4, the long holes 13FE and 13DE formed in the folded portions 2E3F and 2E3D are inserted by the head pins 11FE and 11DE attached to the plates 9FE and 9 DE. At this time, the large diameter portions at the lower portions of the elongated holes 13FE and 13DE are inserted by the headed pins 11FE and 11 DE. After the insertion, if the intermediate portion side plate 2E is slightly lowered, the positions of the long holes 13FE and 13DE are also slightly lowered, and the headed pins 11FE and 11DE move to the small diameter portions in the upper portions of the long holes 13FE and 13DE, and as shown in fig. 6, the head portions of the headed pins 11FE and 11DE are brought into a connected state in which the head portions are prevented from coming off. In fig. 6, the folded portions 2E3F, 2E3d of the intermediate side plate 2E are positioned on the back side of the plates 9FE, 9DE, and the long holes 13FE, 13DE are blocked.
As described above, the plates 9FE and 9DE have an integral plate-like structure that is not divided in the height direction, and have a dimension in the entire height direction when viewed from the inside of the car. Therefore, even in the structure assembled by fitting the intermediate portion side plate 2E last, when the intermediate portion side plate 2E and the coupling portion side plates 2D and 2F are coupled, the coupling portions thereof are sealed by the plates 9FE and 9DE over the entire height direction on the back surface side, and function as light blocking members. This prevents various lights in the hoistway from entering the car through the connection portion.
Further, by using the plates 9FE and 9DE, it is possible to attach a plurality of headed pins 11FE and 11DE at predetermined intervals in the height direction thereof, and to firmly connect the connection portion side plate 2F and the intermediate portion side plate 2E at a plurality of positions, and therefore, it is possible to improve the strength of the connection portion.
Fig. 8 and 9 are a plan view and a main portion enlarged view of the coupling portion showing a coupling completed state of the coupling portion side plate 2F and the intermediate portion side plate 2E.
A plate 9FE is disposed on the back side of the folded portion 2F3 of the coupling portion side plate 2F, and the two are fixed by a rivet 14. At this time, the joint side plate 2F and the plate 9FE are already positioned and fixed. Although not shown in detail, the other plate 9DE is similarly fixed to the side of the coupling portion side plate 2D shown in fig. 4. Therefore, as shown in fig. 4, the operator can insert the intermediate portion side plate 2E from the inside of the car into the space between the coupling portion side plate 2D and the coupling portion side plate 2F, and can couple the long holes 13FE and 13DE to the coupling portion side plate 2D and the respective headed pins 11FE and 11DE on the coupling portion side plate 2F side as described above. At this time, the folded portions 13FE and 13DE contact the front sides of the plates 9FE and 9DE of the coupling portion side plates 2F and 2D, and the middle portion side plate 2E is accurately positioned.
As described above, the long holes 13FE, 13DE are formed in the folded portions 2E3F, 2E3D of the intermediate side plate 2E, and the headed pins 11FE, 11DE are fixed to the front side of the plate 9 at positions corresponding to the long holes 13FE, 13 DE. The headed pins 11FE and 11DE are made of, for example, resin. Although detailed description is omitted in fig. 5 and 6, the headed pins 11FE and 11DE are fixed to the plates 9FE and 9DE by rivets 16 at opposite head-side ends of the headed pins 11FE and 11DE, and metal washers 15 are interposed between the head-side ends of the headed pins 11FE and 11DE and the rivets 16, as shown in fig. 8. In this way, the metal washer 15 is disposed on the front side of the headed pins 11FE and 11 DE.
Here, although one of the headed pins 11FE and 11DE is illustrated, all of the headed pins 11FE and 11DE disposed at a predetermined interval in the height direction have the same configuration. Such plates 9FE, 9DE are pre-constructed before assembly using a structure having headed pins 11FE, 11 DE.
When the intermediate side plate 2E is slightly lifted up and the headed pins 11FE and 11DE are inserted into the large diameter portions of the long holes 13FE and 13DE formed in the folded portions 2E3F and 2E3D, the folded portions 2E3F and 2E3D are sandwiched between the heads of the headed pins 11FE and 11DE and the plates 9FE and 9 DE. Thereafter, when the intermediate-portion side plate 2E is slightly lowered toward the floor of the car, the headed pins 11FE and 11DE move to the small-diameter portions of the elongated holes 13FE and 13DE, and are firmly connected as shown in the drawing.
As is clear from the description of the connection section, if the headed pins 11FE and 11DE are made of resin, the headed pins 11FE and 11DE can be easily inserted into the elongated holes 13FE and 13DE, or the headed pins 11FE and 11DE can be moved from the large diameter portions to the small diameter portions of the elongated holes 13FE and 13 DE. However, it is also considered that since the resin headed pins 11FE and 11DE deteriorate with time, if the headed pins 11FE and 11DE are sandwiched between the plates 9FE and 9DE and the metal washer 15 in advance, the metal washer 15 can prevent the folded portions 2E3F and 2E3D from falling off even if the headed pins 11FE and 11DE are damaged.
In the above-described embodiment, the headed pins 11FE and 11DE are provided on the side of the coupling portion side plates 2D and 2F, and the long holes 13FE and 13DE are formed on the side of the intermediate portion side plate 2E, but the headed pins 11FE and 11DE and the long holes 13FE and 13DE may be formed in reverse. Among them, since the headed pins 11FE and 11DE, the metal washer 15, and the like can be fixed in advance to the plates 9FE and 9DE, it is preferable to simply form the elongated holes 13FE and 13DE on the intermediate side plate 2E side.
As described above, the elevator car according to the present invention is an elevator car in which an intermediate side plate is mounted between left and right coupling portion side plates disposed on the back side of an elevator floor surface, the elevator car including: left and right coupling portion side plates and an intermediate portion side plate, the left and right coupling portion side plates and the intermediate portion side plate being formed of a plate material having a U-shaped cross section, an end portion of which reaches the folded portion from the surface portion via the side portion; a height-direction plate fixed to the turn-back portions of the left and right coupling-portion side plates and extending toward the middle-portion side plate; and a protrusion provided on one of the folded portion of the intermediate side plate and the extending portion of the plate extending toward the intermediate side plate, and an engagement portion provided on the other, wherein the protrusion and the engagement portion are engaged with each other, whereby the intermediate side plate is mounted between the left and right coupling side plates.
According to patent document 1, the strength is problematic because the engagement structure is formed by the side portions of the plate material having a U-shaped cross section, but according to the structure of the present invention, the strength of the connection portion between the adjacent side plates can be improved by the folded-back portion.
further, according to the embodiment of the present invention, work can be performed from the floor surface. In this case, the plate in the height direction, which is fixed to the folded portions of the left and right coupling portion side plates and extends toward the intermediate portion side plate, functions as a stopper when fitted into the intermediate portion side plate, and therefore, the operation can be performed safely and reliably.
The present invention is not limited to the above-described embodiments, and various modifications are also included. For example, the above-described embodiments are described in detail for the purpose of facilitating understanding of the present invention, and the present invention is not necessarily limited to include all the structures described.
