Description
BACKGR011ND OF TH3i~: INVENTION
This invention relates to a man conveyor such as an escalator.
An escalator which is typical of man conveyors is arranged as follows: Endlessly continuous steps connected one another are placed between a pair of balustrades positioned on the transversel~ both outsides of steps, respectively, and driven by an upper and lower drive units, being guided by tracks on there upper line as well as by another tracks on there return, thereby travelling on tracks. In addition, a pair of endless hand rails, on each side, are guided on the balustrades on their upper line, and by guide rollers on their return run, and travel at the same speed and in the same direction with the endlessly continuous steps.
An escalator of this type includes a main frame body on the both sides consisting of an upper main member and a lower main member, and subsidiary members fixed thereto, thus providing a truss construction. In addition, track supporting members are rigidly connected to the subsid-iary members positioned on the both sides of steps in the transverse direction and cantilever track supporting beams are fixed to the each subsidiary members, while tracks for an upper line of the step are fixed to the track supporting members and the tracks for the return of steps are fixed to the cantilever track supporting beams, respectively.
Step-supporting wheels attached to the side edges of steps roll on the aforesaid tracks, being driven by step chains ;. which connect the steps into an endless form. Guide ; 30 rollers for use with the hand-rails are attached to guide-roller-supporting bases secured to the subsidiary members ~"
z in the main frame body, and roll and guide the handrails on their return. In addition, the lower main members in the main frame body on the both sides are connected together rigidly by connecting members, to which is secured a drip pan adapted to receive lubricating oils fed to step-chains and tracks or dusts carried by pas-sengers. As has been described, the main frame body is of a welded truss construction consisting of upper main members, lower main members and subsidiary members, which 10 are independent of each other, so that a large number of members have to be used. In addition, the subsidiary members in general have varying lengths depending on the positions thereof, i.e., in upper and lower horizontal step portions (entrance and exit portions), or in in-termediate inclined portions. Still furthermore, the subsidiary members should bear various kinds of stresses, unlike the main members, so that subsidiary members of varying sizes and lengths are required, resulting in a complicated main frame body. Yet furthermore, indepen-20 dent members are welded together to provide a trussconstruction, thereby incurring assembly errors and hence lowering the dimensional accuracy of tracks. As a result, there is required an expenditure of much time and efforts for correcting dimensional errors, preparation of materials, quality control of members, and accuracy in assembly. Furthermore, supporting beams and supporting members consist of entirely independent members which are welded to the subsidiary members, thus suffering from the shortcomings similar thereto.
For allowing endless steps to travel smoothly in carrying passengers with safety, the dimensional accuracy Z
of tracks upon attaching should be highly controlled.
However, these rails have to be fixed in supporting members or supporting beams welded to the subsidiary members of a main frame body, resulting in an assembly operation in narrow spaces within the main frame body, with the accompanying lowered operational efficiency, thus dictating much time and efforts and high level of skill. In addition, even if the supporting bases are attached normally or properly, the supporting beams provide a canti-lever construction, so that the sup-porting beams are susceptible to deformation due to vertical loads given by such as passengers, steps and the like, thus leading to improper dimensional accuracy of tracks, thereby hindering smooth travelling of steps.
While description has been had for an escalator in conjunction with the shortcomings thereof, man-conveyors such as electrically driven passages, in general, all suffer from the shortcoming similar thereto.
SUMMARY OF T~E INVENTION
It is an object of the present invention to provide a man-conveyor which is simple in construction and allows easy assembly and dimensional adjustment.
According to the present invention, there is provided a man conveyor comprising: a continuous flight of steps formed from a plurality of steps which are connected with one another by connecting members such as chains into an endless form which is disposed in a longitudinal running direction, each 1~7~;22 of said steps having front and rear wheels on opposing transverse sides; guide tracks disposed beneath said front and rear wheels and extending in the running direction of said steps so as to guide said front and rear wheels; main frame members arranged at opposite transverse sides of said continuous flight of steps and extending the length thereof, each main frame member consisting essentially of an upper and a lower horizontal portion and a vertical por-tion interconnecting said horizontal portions; transverse beams mounted on and interconnecting the upper horizontal portions and tran~sverse connecting members place beneath and interconnecting the lower horizontal portions to form a box-like transverse cross section shape; and supporting brackets independent of the main frame members, and carried by the transverse beams while extending in the longitudinal direction of said flight of steps, said brackets supporting said guide tracks for said front and rear wheels.

Fig. 1 is a side view of an escalator showing one embodiment of the present invention;
Fig. 2 is an enlarged partial cross-sectional view of the escalator, taken along the line II-II of Fig. l; and Figs. 3 to 6 are cross-sectional views of essential parts of other embodiments of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
An outline of an escalator embodying the present inven-tion will now be described in more detail in conjunction with Figs. 1 and 2. Provided within each of a pair of bal-ustrades 1 is a main frame member 4 of a beam form, which is made of 'I' steel. Each of the main frame members 4 consists of an upper and lower horizontal flange portion . . .~, . --, ~ . .
11~7Z;~'Z
2, 2', respectively, and a vertical web portion 3 between the flange portions 2, 2'. Transverse beams 5 are secured to the upper flange portions 2 of the main frame members 4, while transverse connecting members 6 are secured to the lower flange portions 2'. Thus, there is formed a box-type main frame body. In addition, track supporting brackets 16, 17 are secured to the transverse beams 5, while tracks 9, 10 for the upper line are integrally secured to ~he supporting brackets 16, and tracks 11, 12 for the return run are integrally secured to the support-ing brackets 17. Guide rollers adapted to guide a hand-rail 13 on its return are mounted by the medium of guide-roller supporting brackets (not shown) on the upper edge portions of the main frame members 4.
Front wheels 7 and rear wheels 8 attached to the left and right sides of steps 15 roll and travel on the tracks 9 to 12, while hand-rail 13 travels on the guide rollers on its return.
In this embodiment, an 'I' steel beam having an 'I' shaped cross-section is used as the main frame member 4, while the upper flange portions 2 are coupled together by transverse beams 5, and the lower flange portions 2' are ; coupled together by transverse connecting members 6 which support a drip pan 22 thereon, thereby forming a main frame body. Thus, the main frame body according to the present invention is not of such a construction as that of the prior art, in which independent members are assembled or welded together for providing a truss construction.
In contrast thereto, the construction of the man conveyor according to the present invention is simple, and provides ease of assembly and toughness because of a box-shaped -~ construction of the main frame body.
~ - 5 -. , .
1107;~
As is clear from the foregoing, the construction of the main frame body is simplified, and in addition, the only portions which require dimensional accuracy upon assembly of the main frame body are the upper horizontal flange por-tions 2 of the main frame member 4, to which the transverse beams 5 holding tracks 9 to 12 are to be secured, and to which guide rollers are to be attached, thereby allowing easy assembly and dimensional adjustment of the main frame body. In addition, the supporting brackets 16, 17 for tracks 9 to 12 each support two tracks such as 9, 10 and 11, 12 respectively, thus improving the efficiency of the attaching operation.
Furthermore, the rail supporting brackets 16, 17 are ; secured to the transverse beams 5, so that the rail sup-porting brackets 16, 17 may bear vertical loads acting on the tracks 9 to 12 in the vertical direction, i.e., in the same direction as that of the loads, thus preventing defor-mation of guide rails 9 to 12, and maintaining dimensional accuracy thereof achieved upon assembly, for a long period of time.
; As a result, improper dimensional adjustment of guide rails due to improper assembly, and deformation of guide rails due to loads may be completely prevented, thus avoid-s ing zig-zag travelling of steps and resulting vibrations and noises, so that there may be achieved an escalator pro-viding high and consistent performances for a long period of time.
On the other hand, according to the prior art escala-tor, the rail-supporting members support respective rails individually, and are welded to the main frame body, so that the rails have to be assembled in the main frame body within a limited narrow space therein 7;~,Z
and adjusted for proper dimensions. In contrast thereto, according to this embodiment of the present invention, a pair of tracks 9, 10 for the upper line and a pair of tracks 11, 12 for the return on one side may be inte-grally supported by the supporting brackets, 16, 17, as an integral construction, respectively, and thereafter the assemblies of tracks and supporting brackets may be fixed in the main frame body, respectively. As a resùlt, before the aforesaid tracks are constructed in the main frame body, several tracks may be assembled, thus allow-ing easy dimensional adjustment and an improved attaching operation of the aforesaid assemblies, when assembled into the main frame body Meanwhile, in the embodiment shown in Fig. 2, descrip-tion has been given of the supporting brackets each adapted to integrally support a pair of tracks for an upper line or a return on one side of the escalator, respectively.
Alternatively, Fig. 3 shows a single supporting bracket 18 adapted to integrally support four tracks for upper line and return on one side. Further alternatively, Figs.
4 and 5 show supporting brackets 19, 20 which are each adapted to support four tracks 9, 10 on the upper line on the left and right sides or four tracks 11, 12 on the return on the left and right sides, integrally, at the same bracket. In addition, Fig. 6 shows a single sup-porting bracket 21 which may support eight tracks 9 to 12 for the upper line and return on the both sides integrally.
In case two or more tracks 9 to 12 are integrally supported by a single supporting bracket, the tracks 1~7~2 are fixed to the supporting brackets at intervals of 0.5 to 1.5 m. More particularly, two to eight of guide rails 9 to 12 are rigidly assembled on several track-supporting brackets 16 to 21, and then the brackets are secured to the transversc beams 5 which are in turn secured to the upper flange portions 2 of the main frame members 4 at the same interval as that of the supporting brackets.
As shown in Figs. 4 to 6, transverse connecting por-tions l9a, 20a, 21a may be commonly used as transverse beams 5, and in such a case, rail supporting bases 19 to 21 are directly secured to the main frame members 4, without using the transverse beams 5.
From viewpoints of manufacture and transportation, respective tracks 9 to 12 are generally cut a suitable length as shown by the lines A-A, B-B in Fig. 1. In this embodiment, as well, tracks are secured to their support-ing brackets to provide integral constructions for each division of the escalator.
As is apparent from the foregoing description, the positional relationship of mutual guide rails may be adjusted independently from the dimensional accuracy of the main frame body, and yet the adjustment or assembly of the tracks may be carried out outside of the main frame body, thus providing ease of adjustment. In addition, assembly of tracks and main frame body may be carried out in line with each other, or at the same time, resulting in much improvement in operational efficiency. In addition, track supporting bracket 16 to ; 21 may be secured to the transverse beams 5 before-hand, ~7~
and then tracks 9 to 12 may be secured to the supporting brackets. In this case, two or more track supporting brackets may be secured in position to the main frame body according to a single attaching operation of a beam, thereby saving the effort required for the attaching operation~
While the main frame members 4 of an 'I' shaped cross section ('I' steel) are used in the aforesaid embodiment, a section steel of a 'U' shaped cross section may be used, with their open sides being directed inwardly or outwardly, with the same results achieved as those of the preceding case. In addition, while description has been had for the case of an escalator, the present invention is apparently applicable to general type man-conveyors such as electri-cally driven passages and the like.
As is apparent from the foregoing, the main frame body according to the present invention is not only tough but also its construction is simplified, thereby permitting ease of assembly of respective components such as tracks, as well as ease of adjustment thereof, with the resulting improvement in efficiency of the attaching operation o~
respective components, and reduction in manufacturing cost.
_ g
Front wheels 7 and rear wheels 8 attached to the left and right sides of steps 15 roll and travel on the tracks 9 to 12, while hand-rail 13 travels on the guide rollers on its return.
In this embodiment, an 'I' steel beam having an 'I' shaped cross-section is used as the main frame member 4, while the upper flange portions 2 are coupled together by transverse beams 5, and the lower flange portions 2' are ; coupled together by transverse connecting members 6 which support a drip pan 22 thereon, thereby forming a main frame body. Thus, the main frame body according to the present invention is not of such a construction as that of the prior art, in which independent members are assembled or welded together for providing a truss construction.
In contrast thereto, the construction of the man conveyor according to the present invention is simple, and provides ease of assembly and toughness because of a box-shaped -~ construction of the main frame body.
~ - 5 -. , .
1107;~
As is clear from the foregoing, the construction of the main frame body is simplified, and in addition, the only portions which require dimensional accuracy upon assembly of the main frame body are the upper horizontal flange por-tions 2 of the main frame member 4, to which the transverse beams 5 holding tracks 9 to 12 are to be secured, and to which guide rollers are to be attached, thereby allowing easy assembly and dimensional adjustment of the main frame body. In addition, the supporting brackets 16, 17 for tracks 9 to 12 each support two tracks such as 9, 10 and 11, 12 respectively, thus improving the efficiency of the attaching operation.
Furthermore, the rail supporting brackets 16, 17 are ; secured to the transverse beams 5, so that the rail sup-porting brackets 16, 17 may bear vertical loads acting on the tracks 9 to 12 in the vertical direction, i.e., in the same direction as that of the loads, thus preventing defor-mation of guide rails 9 to 12, and maintaining dimensional accuracy thereof achieved upon assembly, for a long period of time.
; As a result, improper dimensional adjustment of guide rails due to improper assembly, and deformation of guide rails due to loads may be completely prevented, thus avoid-s ing zig-zag travelling of steps and resulting vibrations and noises, so that there may be achieved an escalator pro-viding high and consistent performances for a long period of time.
On the other hand, according to the prior art escala-tor, the rail-supporting members support respective rails individually, and are welded to the main frame body, so that the rails have to be assembled in the main frame body within a limited narrow space therein 7;~,Z
and adjusted for proper dimensions. In contrast thereto, according to this embodiment of the present invention, a pair of tracks 9, 10 for the upper line and a pair of tracks 11, 12 for the return on one side may be inte-grally supported by the supporting brackets, 16, 17, as an integral construction, respectively, and thereafter the assemblies of tracks and supporting brackets may be fixed in the main frame body, respectively. As a resùlt, before the aforesaid tracks are constructed in the main frame body, several tracks may be assembled, thus allow-ing easy dimensional adjustment and an improved attaching operation of the aforesaid assemblies, when assembled into the main frame body Meanwhile, in the embodiment shown in Fig. 2, descrip-tion has been given of the supporting brackets each adapted to integrally support a pair of tracks for an upper line or a return on one side of the escalator, respectively.
Alternatively, Fig. 3 shows a single supporting bracket 18 adapted to integrally support four tracks for upper line and return on one side. Further alternatively, Figs.
4 and 5 show supporting brackets 19, 20 which are each adapted to support four tracks 9, 10 on the upper line on the left and right sides or four tracks 11, 12 on the return on the left and right sides, integrally, at the same bracket. In addition, Fig. 6 shows a single sup-porting bracket 21 which may support eight tracks 9 to 12 for the upper line and return on the both sides integrally.
In case two or more tracks 9 to 12 are integrally supported by a single supporting bracket, the tracks 1~7~2 are fixed to the supporting brackets at intervals of 0.5 to 1.5 m. More particularly, two to eight of guide rails 9 to 12 are rigidly assembled on several track-supporting brackets 16 to 21, and then the brackets are secured to the transversc beams 5 which are in turn secured to the upper flange portions 2 of the main frame members 4 at the same interval as that of the supporting brackets.
As shown in Figs. 4 to 6, transverse connecting por-tions l9a, 20a, 21a may be commonly used as transverse beams 5, and in such a case, rail supporting bases 19 to 21 are directly secured to the main frame members 4, without using the transverse beams 5.
From viewpoints of manufacture and transportation, respective tracks 9 to 12 are generally cut a suitable length as shown by the lines A-A, B-B in Fig. 1. In this embodiment, as well, tracks are secured to their support-ing brackets to provide integral constructions for each division of the escalator.
As is apparent from the foregoing description, the positional relationship of mutual guide rails may be adjusted independently from the dimensional accuracy of the main frame body, and yet the adjustment or assembly of the tracks may be carried out outside of the main frame body, thus providing ease of adjustment. In addition, assembly of tracks and main frame body may be carried out in line with each other, or at the same time, resulting in much improvement in operational efficiency. In addition, track supporting bracket 16 to ; 21 may be secured to the transverse beams 5 before-hand, ~7~
and then tracks 9 to 12 may be secured to the supporting brackets. In this case, two or more track supporting brackets may be secured in position to the main frame body according to a single attaching operation of a beam, thereby saving the effort required for the attaching operation~
While the main frame members 4 of an 'I' shaped cross section ('I' steel) are used in the aforesaid embodiment, a section steel of a 'U' shaped cross section may be used, with their open sides being directed inwardly or outwardly, with the same results achieved as those of the preceding case. In addition, while description has been had for the case of an escalator, the present invention is apparently applicable to general type man-conveyors such as electri-cally driven passages and the like.
As is apparent from the foregoing, the main frame body according to the present invention is not only tough but also its construction is simplified, thereby permitting ease of assembly of respective components such as tracks, as well as ease of adjustment thereof, with the resulting improvement in efficiency of the attaching operation o~
respective components, and reduction in manufacturing cost.
