Abstract
Description
- The present invention relates to a bridge-type conveyance system for crossing roads and the like. More particularly, the invention relates to a pedestrian bridge-type system for crossing city streets with high traffic levels, suitable to improve road conditions. Such a system is known from US-A-4,821,845.
- It is known that crossing roads is becoming increasingly difficult for pedestrians owing to the growing amount of vehicle traffic.
- Crossing at traffic lights forces pedestrians to wait for the green light in order to cross the road.
- Crossing a road at locations which are not served by traffic lights is particularly dangerous, besides being forbidden by the law; accordingly, vehicle traffic heavily affects the movement of pedestrians in city streets.
- Although the provision of underpasses is functional from the point of view of safety and speed in crossing, it forces pedestrians to walk down and then up stairways, with consequent problems for the disabled and for senior citizens and children.
- The aim of the present invention is to provide a bridge-type conveyance system, particularly for roads and the like, which allows pedestrians to cross automatically and without waiting times and allows to reduce the amount of vehicle emissions inhaled at the roadside.
- Within the scope of this aim, an object of the present invention is to provide a bridge-type conveyance system for crossing roads and the like which does not entail performing an excavation beneath the roadbed, as occurs in the case of the provision of underpasses.
- Another object of the present invention is to provide a bridge-type conveyance system for crossing roads and the like which allows a substantially continuous crossing of the road involved.
- Another object of the present invention is to provide a bridge-type conveyance system for crossing roads and the like which can also be used as a support for advertising billboards and the like.
- Another object of the present invention is to provide a bridge-type conveyance system for crossing roads and the like which is highly reliable, relatively easy to provide and at competitive costs.
- This aim, these objects and others which will become apparent hereinafter are achieved by a bridge-type conveyance system for crossing roads and the like, characterized in that it comprises a box-like structure which is meant to be arranged transversely to a road and to support a plurality of pedestrian-carrying cars traveling along a closed path, said cars being actuated by actuation means which are connected to kinematic means, for the movement of said cars in a continuous cycle along the structure of said bridge-type system from one side of the road to the other.
- Further characteristics and advantages of the invention will become apparent from the description of a preferred but not exclusive embodiment of the bridge-type system according to the invention, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- Figure 1 is a sectional front elevation view of the bridge-type system according to the present invention;
- Figure 2 is a side elevation view of the bridge-type system according to the present invention;
- Figure 3 is a detail view of the bridge-type system according to the present invention;
- Figure 4 is a sectional view of one of the rails for guiding the car that can move along the bridge-type system according to the invention;
- Figure 5 is another detail view of the bridge-type system according to the invention;
- Figures 6 and 7 are sectional views of safety means used in the bridge-type conveyance system according to the invention, illustrated respectively in two operating conditions.
-
- With reference to the above figures, the bridge-type system according to the present invention, generally designated by the reference numeral 1, comprises a supporting frame which is constituted by a plurality of mutually parallel
vertical uprights 2, arranged at each side of the road on which the bridge-type system is arranged, and by a plurality of transverse connectingelements 3, which are suitable to connect thevertical uprights 2. - Figure 1 is a sectional view of the bridge-type system according to the present invention, illustrating four
vertical uprights 2 and three transverse connectingelements 3 which are meant to interconnect the fourvertical uprights 2 arranged on one side of the road to the fourvertical uprights 2 arranged on the opposite side. - The supporting frame has a second plurality of
vertical uprights 2 which are arranged so as to face the first plurality ofvertical uprights 2, at each side of the road, and has a similar plurality of connectingelements 3 which are arranged so as to face the first plurality of connectingelements 3. - In this manner, a substantially box-like structure is provided, also by way of the presence of connecting cross-members 4 which interconnect the first and second pluralities of
vertical uprights 2 and the first and second pluralities of connectingelements 3. - The bridge-type system thus formed is anchored, for example by bolting or the like, to a box-
like structure 5 which is buried at each side of the road and is internally hollow. - The box-like structure has anchoring
elements 6 which are arranged vertically and correspond to the plurality ofvertical uprights 2. - Connection of the bridge-type system according to the invention therefore occurs by connecting the
uprights 2 to theanchoring elements 6. - At least one of the box-
like structures 5 buried at the sides of the road over which the bridge-type system is to be installed is furthermore used to accommodate movement means 10, conveniently constituted by an electric motor, for actuating a plurality ofcars 15 which are meant to follow the profile of the bridge-type system so as to allow pedestrians to cross from one side of the road to the other by using the car. -
Guide rails 18 are provided at two of thevertical uprights 2 and run along two of the connectingelements 3, so as to constitute a closed path between the first plurality ofvertical uprights 2, the second plurality ofvertical uprights 2 on one side of the road, up to the first and second pluralities of vertical uprights at the opposite side of the road. - The plurality of cars move so as to be spaced from each other along said closed path formed by the guide rails 18. The guide rails 18 accordingly form a circuit for the cars.
- In this manner a sort of closed circuit for the
cars 15 is obtained, which are actuated by themotor 10 by way of kinematic means which are conveniently described hereinafter. - The continuous actuation of the
cars 15 allows pedestrians to cross the road by using said cars, in practice without having to wait, since the passage of the car at the ground and the arrival of a subsequent car are mutually separated by a time interval. - The number of
cars 15 is of course constrained by the length of the bridge-type structure, i.e., by the length of the connectingelements 3, and the purpose is to convey the pedestrians from one side of the road to the other by continuous rotation. - At the corners of the
guide rails 18 there are providedsprockets 20 which allow the passage and travel of achain 21 which supports ashaft 22 so that it is rigidly coupled thereto; said shaft acts as a support for thecar 15. - As shown in detail in Figure 3, the
shaft 22 is rigidly connected to one of the links of thechain 21 on one side and to a link of achain 21, similar to the preceding chain, at the other side. The latter side slides in asimilar guide rail 18 of the box-like structure of the bridge-type system formed by the facing plurality ofuprights 2, which are connected bycross-members 4. - The
shaft 22 that supports thecar 15 further has, on the outside of the connection to thechain 21, at least onewheel 23 for each end of theshaft 22, allowing said car to travel within theguide rail 18, keeping the chain raised and free to slide within the guide rail. - Figure 4 is a sectional view of the substantially C-
shaped guide rail 18 which has asuitable step 24 for the movement of thewheels 23. - A
tooth 45 is provided at the shorter sides of the C-like shape of theguide rail 18 and allows the guided passage of thechain 21. - The
motor 10 is connected, by means of itsdriving shaft 25, to asprocket 26 which is accommodated in the box-like structure 5 that is buried at the sides of the road; saidsprocket 26 is in turn connected, by means of achain 27, to asecond sprocket 28 which is in turn pivoted, by means of apivot 29, to thesprocket 20 which allows to drive thechain 21. - Covering
housings 35, shaped substantially like a circular sector, are provided at the corners of theguide rails 18. - The
cars 15 stop and start, in order to allow pedestrians to access them, preferably in an intermediate position between one vertical upright 2 and the upright that is adjacent thereto, so as to allow easy passage of the pedestrians into and out of thecars 15. - The box-
like structures 5 buried at the sides of the road act as foundations for the bridge-type system and ensure its necessary stability. - Said box-
like structures 5 are furthermore conveniently covered by a covering element so as to be perfectly flush with the roadside paving. - Figures 6 and 7 illustrate safety means for preventing a sudden breakage of the
driving chain 21 from having dangerous consequences. Said safety means conveniently comprise a hook-like element 40 which is pivoted below theguide rail 18 in which thedriving chain 21 runs; said element is provided withelastic means 41 which are suitable to connect its lower end to the edge of said guide rail, whereas its upper hook-shaped end protrudes partially into theguide rail 21. - When the
chain 21 moves, as shown in Figure 6, the links of thechain 21, in their uniform movement (for example toward the left, as indicated by the arrow in Figure 6), press down the head of the hook-like element 40 and can therefore run freely within theguide rail 18. - If the
chain 21 breaks, the hook-like element 40 moves into the position shown in Figure 7 so as to contrast the reverse movement (to the right in the example of Figure 7) of thechain 21, since the elastic means are no longer kept elongated by the lowering of the head of the hook-like element due to the passage of the chain and therefore allow the engagement of said hook-like element with the portion of thechain 21 that moves, in this exemplifying case, to the right. - The bridge-type system structure thus conceived is further covered with a plurality of cladding elements which are suitable to conceal the
uprights 2 and the connectingelements 3 as well as thecross-members 4, allowing only access to thecars 15. - The cladding elements of the bridge-type system according to the invention can be used to apply thereto advertising billboards and the like.
- In practice it has been observed that the bridge-type conveyance system according to the invention fully achieves the intended aim and objects, since it allows easier crossing of the road by pedestrians without having to wait for the idle times inevitably entailed by a traffic light and at the same time it avoids the use of stairways as normally occurs when underpasses are built.
- The bridge-type system thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.
- Thus, for example, it is possible to provide for the presence of two actuation motors, one of which is meant to be used in emergency situations which involve a failure of the motor normally used to drive the cars along the structure of the bridge-like system.
- All the details may also be replaced with other technically equivalent elements.
- In practice, the materials employed, so long as they are compatible with the specific use, as well as the dimensions, may be any according to requirements and to the state of the art.
- The disclosures in Italian Patent Application No. MI98A002869 from which this application claims priority are incorporated herein by reference.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
