Description

BICYCLE WITH PASSENGER SEAT
The invention concerns a bicycle with a seat for a passenger, especially suited for transporting a child who is offered the opportunity to contribute towards the muscular effort required to make the vehicle move forward. It is known that bicycles, even though they are means of transport designated for only one person, they are sometimes converted, whether for need or recreation, so they may transport a child as a passenger.
It is common knowledge that a bicycle basically consists of a frame, provided with a seat where the rider sits, that runs on the ground by means of a pair of tyred wheels, one with traction at the back and one at the front with steering by means of handlebars.
The rider uses the muscular force of his legs to drive a set of pedals held by the frame and mechanically connected by means of linkage systems to the back traction wheel, while his hands grip the handlebars that act on the fork that holds the front wheel.
The need to transport a child is usually overcome by mounting on the bicycle a detachable seat easily found on the market.
These seats are usually fixed to the frame in a position between the handlebars and the seat or behind the actual seat and over the back wheel. The main inconvenience of known products is that the young passenger, comfortably sitting on the seat, feels he is a dead weight since he neither participates in directing the bicycle nor in the physical effort needed to make it move.
Another inconvenience is that the young passenger does not have the opportunity to learn or exercise the physical motions required to make the vehicle move.
An additional inconvenience is that, in the case where the passenger seat is placed behind the seat, the rider does not have a visual, direct control of the child. The scope of this invention is to overcome the aforementioned inconveniences.
In particular a first scope of this invention is to produce a bicycle that allows a child to be transported safely and comfortably.
Another scope of this invention is to produce a bicycle that gives the child the opportunity to learn the motions necessary to make the vehicle move. An additional scope of this invention is to produce a bicycle that gives the child the opportunity to contribute towards the physical effort of the rider to make the vehicle move. Another scope is to produce a bicycle that gives the rider continuous visual control over the child being transported.
Said scopes are achieved by a bicycle that in accordance with the main claim comprises a frame having a seat and running on the ground by means of a pair of wheels, one driving at the back, mechanically connected by means of first linkage systems to a first set of pedals driven by the rider and held by the frame, and one at the front in line with the back wheel and fixed to a fork connected to handlebars, guided by said rider, being characterised in that they comprise a loadbearing structure, connected with said front wheel, that supports a seat where the passenger sits and a second set of pedals, that can be driven by said passenger and connected by means of second linkage systems to said front wheel.
An advantage of the bicycle invention is that it allows the child to learn the motions for riding and guiding the bicycle in a simple, enjoyable and hazard- free way. Another advantage of the invention is that it allows the child to feel he is playing an active part in guiding the vehicle, thereby increasing his interest. Said scopes and advantages shall be better explained during the description of a preferred form of execution of the invention given as a guideline but not a limitation and illustrated in the attached diagrams, where:
- fig. 1 illustrates a side view of the bicycle invention; - fig. 2 illustrates a front view of the bicycle in fig. 1 ;
- fig. 3 illustrates the side view of part of the linkage system mounted on the back wheel of the bicycle in fig. 1 ;
- fig. 4 illustrates the side view of part of the linkage system mounted on the front wheel of the bicycle in fig. 1 ; - fig. 5 illustrates a detail of a construction component of the bicycle in fig. 1 ;
- fig. 6 illustrates a variant in execution of a detail of a construction component of the bicycle in fig. 1.
The overall bicycle invention is illustrated in fig.'s 1 and 2, where it is generally indicated by 1. It comprises a frame 2, provided with a seat 3, which runs on the ground by means of a back driving wheel 4 and a front wheel 5 with steering, in line with the back wheel 4 and fixed to a fork 6 connected to handlebars 7 that are gripped by the rider C. The back wheel 4, by means of a first linkage system, generally indicated by 8, is connected mechanically to a first set of pedals 9 held by the frame 2 and driven by the rider C.
This first linkage system 8, as illustrated in fig. 3, is protected by a first guard 8a and comprises a first freewheel 10 connected with the back wheel 4 connected, by means of a first chain 11 , to a first chain wheel 12 connected with the first set of pedals 9 driven by the rider C.
The invention involves a loadbearing structure 13 connected with the front wheel 5 of the bicycle 1 , which supports a seat 14 where the passenger P sits and a second set of pedals 15 that can be driven by the passenger P, connected by means of a second linkage system 16 to the front wheel 5. The loadbearing structure 13 consists of a second frame 17 coupled mechanically to the fork 6 and to the handlebars 7 of the bicycle 1 and having clamping devices 18 for the seat 14 and second handlebars 19 for the passenger P to grip. The clamping device 18 of the seat 14, illustrated in detail in fig. 5, comprise a first tube section 20 belonging to the second frame 17 designed to be coaxially coupled to a second tube section 21 belonging to the seat 14 where the two become a connected piece by means of a tube collar 22 fitted with a closing clamp 23. It has to be noted that this type of coupling allows the seat 14 to be both adjusted in height according to the height of the passenger P and to be replaced with a saddle or alternatively with any other, different sized or shaped seat.
The passenger P, sitting on the seat 14, grips the second handlebars 19 coupled to the second frame 17 by clamping devices similar to those described earlier, that allow a quick and simple replacement and adjustment to suit the height of the passenger P.
With regard to the second linkage system 16, illustrated in detail in fig. 4, it is protected by a second guard 11a and consists of a second freewheel 24 connected with the front wheel 5 and connected by means of a second chain 25 to a second chain wheel 26 connected with the second set of pedals 15 driven by the passenger P. According to a variant in execution, illustrated in detail in fig. 6, the second linkage systems 30 consist of a friction wheel 31 connected with the second set of pedals 15 and pressing against the front wheel 5 at contact point 32. In this way the passenger P, by driving the second set of pedals 15, turns the friction wheel 31 , which by friction transmits the movement to the front wheel 5.
The passenger P, sitting on the seat 14, gripping the second handlebars 19 and can decide whether or not to contribute towards the effort in moving the bicycle 1 by driving the second set of pedals 15. Variants in execution may prescribe that the second frame 17 need only be fastened to the fork 6 of the bicycle 1 or to the handlebars 7 of the bicycle 1 and that the second handlebars 19 can also be turned around the vertical axis 30. Since it is a connected part of the steering wheel 5, this gives the passenger P the sensation of playing an active part in guiding the bicycle 1.
However the invention has been described with reference to the attached diagrams, it may undergo changes in construction falling under the claims and thereby protected by this patent.
