These main frames 1A and 2A are adjacently arranged and has a total lateral wide WA between the main frames 1A and 2A as shown in Fig. l(b) and Fig. 2.

In Fig. l(a) and Fig. 3, each of newly-established two escalators 3 and 4 comprises a main frame 5A and a main frame 6A, and each of the main frames 5A and 6A is formed with U shape cross-section.

Each of these main frames 5A and 6A is constituted by side frames 5a and 5b and side frames 6a and 6b disposed at both sides, a lateral frame portion Sc and a lateral frame portion 6c for connecting the side frames Sa and 5b, the side frames 6a and 6b and a bottom portion frame 5d and a bottom portion frame 6d.

As shown in Fig. 3, a bottom portion frame 9 connects to between lower portions of the side frames la and ib of the main frames 1A and 2A.

As shown in Fig. 3, a constituting component 7A is arranged in the main frame 5A of the newly-established escalator 3 and a constituting components 8A is arranged in the main frame 6A of the newly-established escalator 4, respectively.

Each of the above constituting components 7A and 8A is constituted by a step 7a and a step 8a, each of the steps 7a and 8a is arranged with an endless shape and can circulate and can move to a side of a forward passage side and at a backward passage side, balustrades 7c and balustrades 8c, each of the balustrades 7c and Sc is supported by the above stated side frames 5a, Sb and 6a, 6b and can stand upright along to the moving directions at both sides of the steps 7a and 8a, hand rails 7b and hand rails 8b, each of the handrails 7b and 8b is guided by peripheral edges of the above stated balustrades 7c and Sc and can move periodically with the steps 7a and 8c.

Each of the above constituting components 7A and 8A is constituted further by an inner deck cover 7d and an inner deck cover 8d, each the inner deck covers 7d and 8d can cover an inside of a base portions of the balustrades 7c and 8c, an outer deck cover 7e and an outer deck cover 8e, each of the outer deck covers 7e and 8e can cover an outside of base portions of the balustrades 7c and 8c, skirt guards 7f which are vertically arranged and can partition between the inner deck cover 7d and the outer deck cover 7e and the step 7a to the forward passage side, skirt guards 8f which are vertically arranged and can partition between the inner deck cover 8d and the outer deck cover 8e and the step 8a to the backward passage side, and rails for guiding the above stated steps 7a and 8a, etc..

The side frames 5a and 6a of the above stated newly-established escalators 3 and 4 are fixed to the side frames la and 2a of the previously-established escalators through connection members 10 as shown in Fig. 3. Further, the bottom portion frames 5d and 6d of the newly-established escalator 3 and 4 are fixed to the bottom portion frame 9 of the previouslyestablished escalators through other connection members 11.

The outer surface portions of the main frames 1A and 1B of the previously-established escalators are covered by the side portion exterior plates 12 and 13 and the bottom portion exterior plate 14. The side portion exterior plates 12 and 13 are fixed to the side frames la and 2a and are provided to extend over from the above stated deck covers 7e and 8e to lower portions of the side frames la and 2a. The bottom portion exterior plate 14 is fixed to the bottom portion frame 9 and covers between the lower ends of the above stated side portion exterior plate 12 and 13.

Next, the procedure of installing the newlyestablished escalators 3 and 4 using a part of the main frames 1A and 2A of the previously-established escalators will be explained.

First of all, as shown in Fig. l(b) and Fig. 2, each of the constituting components of the two previously-established escalators is withdrawn. After that, within the previously-established main frames 1A and 2A, leaving the side frames la and 2a positioned at the most outer portions to the opposite sides and the receiving beam portions le and 2e positioned at the opposite sides, all of the constituting components such as the adjacent side frames 1b and 2b each other, the bottom portions lc and 2c, and the lateral frame portions 1d and 2d, etc. are withdrawn.

Namely, in the previously-established escalators, all constituting components and all constituting members in the a region X performed by meshes (Fig.

l(b)) and a region Y (Fig. 2) are withdrawn. Only the side frames la and 2a and the receiving beam frame portions le and 2e of the most outside portion of the left portion and the right portion of the main frames 1A and 2A are left to remain and then a receiving space for receiving the newly-established escalators 3 and 4 is secured.

Next, as shown in Fig. l(a), Fig. l(b) and Fig. 3, since the bottom portion frame 9 is arranged by spanning between the bottom portion of the side frames la and 2a of the main frames 1A and 2A of the remaining previously-established escalators, a receiving and supporting frame is formed. This receiving and supporting frame receives and supports the main frames 5A and 6A of the newly-established escalators 3 and 4.

The receiving and supporting frame has a total lateral width WA as shown in Fig. 3 and has U shape crosssection.

At this time point, since the withdrawal of the constituting components and the constituting members of the previously-established escalators and further a partial remodeling of the main frames 1A and 2A are merely carried out, a wide remodeling construction work of the construction building where the escalators are installed is not carried out.

Next, the newly-established escalators 3 and 4 being put side by side are installed in the receiving and supporting frame which is formed with U crosssectional shape having the lateral width of WA. First of all, the newly-established main frames 5A and 6A having a whole lateral wide WB of two escalators part of the newly-established escalators 3 and 4 are fallen down to the above stated receiving and supporting frame along to the perpendicular lines m-n-o-p shown in Fig.

1 and the newly-established main frames 5A and 6A are fixed through the connection members 10 and the connection members 11.

In this time, the steps 7a and 8a can put in to the main frames 5A and 6A in advance, however it is desirable to receive and support the main frames 5A and 6A being existed before a condition of the put-in of the steps 7a and 8a to the receiving and supporting frame, under the consideration of the fixture working according to the connection members 10 and the connection members 11 of the main frames 5A and 6A to the receiving and supporting frame.

After the newly-established main frames 5A and 6A have received in the receiving and supporting frame which has been remodeled the previously-established main frames and have carried out the centering working, the above stated steps 7a and 8a have put into (however, in a case where the steps 7a and 8a have put into the main frames 5A and 6A in advance, the above stated putin working is unnecessary). The balustrades 7c and Sc are arranged to each of the side frames 5a, 5b and 6a, 6b, and the hand rails 7a and 8b are guided through the balustrades 7c and 8c. Further, by the installation of the side portion exterior plates 12 and 13 and the bottom portion exterior plate 14, the installation about the two newly-established escalators 3 and 4 has completed.

Herein, the reasons why the withdrawal of the side frames 1b and 2d, the bottom portions lc and 2c and the lateral frame portions 1d and 2d which are adjacently to the previously-established main frames 1A and 2A is performed will be explained.

As shown in Fig. 2, each of an inner side lateral width WC formed between the both side frames la and 2a and an inner side lateral width WC formed between both side frames 2a and 2b of the previously-established main frames 1A and 2A is about 1/2 width length of the whole lateral width WA. In a case where the main frames 5A and 6A of the newly-established escalators 3 and 4 are intended to receive in each of the inner side lateral widths WC as shown in Fig. l(a), the above stated case will be explained.

The receiving space will be limited according to the above stated each of the inner side lateral widths WC. However, since each of the outer side lateral widths of the newly-established frames 5A and 6A is substantially to same or slightly larger than the inner side lateral width WC of the previously-established main frames 1A and 2A, from the aspect of the working, the receiving for the newly-established main frames 5A and 6A into each of the inner side lateral widths WC of the previously-established main frames 1A and 2A becomes difficult.

In the first mode of the embodiment according to the present invention, the adjacent side frames 1b and 2b, the bottom portions lc and 2c, and the lateral frame portions 1d and 2d are withdrawn. In the previously-established escalators, a width Wb having 100-200 mm can be secured, such a width Wb is a sum width in which a width formed between the side frames 1b and 2b is added to an adjacent interval Wa between each of the escalators being existed originally.

The above stated width Wb is utilized as a receiving afford degree of the newly-established escalators 3 and 4 against the previously-established main frames 1A and 2A. The afford degree having the width Wb is convenient to attain the receiving working and the renewal working for the renewal escalator.

A deep width Ha of the main frames lA and 2A of the previously-established escalators as shown in Fig.

2 is unnecessary to enlarge and can adopt as it is, namely the steps having the same kind shape as usual can use as the steps of the newly-established escalators.

The construction of the newly-established escalators 3 and 4 will be explained referring to Fig.

3.

Within a range of the inner width WA of two previously-established escalators, the main frames 5A and 6A of the two newly-established escalators 3 and 4 having a total lateral width WB is received. The newly-established escalators 3 and 4 comprise the main frames 5A and 6A and the constituting components 7A and 8A.

Namely, the above stated main frames 5A and 6A comprise the outer portion frames 5a, 6a and 5b, 6b, the lateral frames 56 and 6c, and the bottom portions 5d and 6d, etc. Further, the above stated constituting components 7A and 8A comprise the steps 7a and 8a, the hand rails 7b and 8b, and the balustrades 7c and 8c, etc., but omit a driving machine and a safety apparatus in this figure and this constituting components 7A and 8A are necessary to carry out the passenger transportation.

The important portions are jointed according to the short length connection members 10 and the short length connection members 11 and the outer side frame portions la and 2a are jointed to the outer side portion frames 5a and 6a and the bottom plate 9 is jointed to the inner portion frames 5b and 6b, accordingly a necessary strength for constituting as the main frame of the escalator is secured.

On the other hands, the outer deck covers 7e and 8e which are arranged on the base portion of the balustrades 7c and Sc are constituted to have a relationship Mo > Mi, wherein Mo is a width formed between the outer deck covers 7e and 8e which are positioned toward the opposite sides and Mi is a width formed between the outer deck covers 7e and 8e which are positioned toward the center sides.

The two widths Mo and Mi has the relationship of Mo > Mi. The reason why the width Mo is larger than the width Mi is to cover the upper ends of the side portion exterior plates 12 and 13 which are attached to the outer side of the previously-established main 1A and 2A.

As stated in the above, according to the first mode of the embodiment according to the present invention, in accordance with the withdrawal of each of the constituting components of the parallel arrangement previously-established escalators and the side frames ib and 2b which adjacently positioned to the main frames 1A and 2A, etc., the receiving and supporting frame having U cross-section shape is formed.

This receiving and supporting frame can secure a newly enlarged inner portion space in the remained main frames 1A and 2A. As a result, the two newlyestablished escalators 3 and 4 can receive in the receiving and supporting frame with the afford degree.

Further, by the new enlargement according to the withdrawal of each of the constituting components of the parallel arrangement previously-established escalators and the adjacent side frames 1b and 2b of the main frames 1A and 2A, the installation work for the two newly-established escalators 3 and 4 can carry out easily in a short time.

Further, in a case of the installation working of the two newly-established escalators 3 and 4, since the main frames 1A and 2A of the previously-established escalators can be utilized as the scaffolding, as a result the installation of a monopoly scaffolding and the withdrawal of the monopoly scaffolding are unnecessary, thereby the shortening of the construction period can be attained.

Next, a second mode of the embodiment according to the present invention will be explained referring to Fig. 4.

In Fig. 4, the different constructions in comparison with the mode of the first mode embodiment shown in Fig. 3 are that each of the side frames 5a, 5b of the newly-established main frame 5A and the side frames 6a, 6b and the newly-established main frame 6A is connected by a common long length connection member 15 and also each of the side frame la of the previously-established main frame 1A and the side frame 2a of the previously-established main frame 2A is connected by extending of the same common long length connection member 15, thereby the strength for constituting as the main frame of the escalator can be secured. With the above stated structure, the short length connection member 10 which is required by the second mode embodiment can be unnecessary.

Further, in the second mode embodiment according to the present invention, the common long length connection member 15 supports to cross over the abdominal region of the newly-established escalators 3 and 4 and the right and left both end portions of the common long length connection member 15 are connected to the side frame la of the previously-established main frame 1A and the side frame 2a of the previouslyestablished main frame 2A. Accordingly, in comparison with the first mode embodiment, the second mode embodiment has superior stability for supporting the newly-established escalators 3 and 4.

Further, in each of the first mode embodiment and the second mode embodiment according to the present invention, since the receiving beam frame portions le and 2e of the main frames 1A and 2A of the previouslyestablished escalators are diverted as they are, the wide remodeling such as the shaving of the floor of the construction building is unnecessary. Accordingly, it can dispense with the re-cover of the tiles of the floor surface and no construction building work is necessary.

Further, in each of the first mode embodiment and the second mode embodiment according to the present invention, the two newly-established escalators are arranged in the lateral width of the two previouslyestablished escalators. However, according to demand, in the lateral width of the two previously-established escalators, it is possible to arrange a three newlyestablished escalators. Further, in the lateral width of a three previously-established escalators, it is possible to install a three newly-established escalators.

In each of the first mode embodiment and the second mode embodiment according to the present invention, the escalators arranging in parallel and further inclining to the same direction and the method of installing the same are stated. However, it is possible to adopt the present invention to the moving walks arranging in parallel and further inclining to the same direction and further a case where the moving walks arranging in parallel and toward the same direction in the horizontal.

As stated in the above, according to the present invention, without the wide remodeling the space for receiving the plural newly-established passenger conveyors can be secured easily and the renewal of the previously-established passenger conveyor equipment can be carried out in a short time.
