D~CRIPTION or A PRBFERRED EHBODIHBNT
Referrin4 now to the annexed drawing~, more particularly to Figure 1, the reference numeral 10 deslgnates ln general an emergency supportlng devlce for temporarlly operatlng a blcycle ln case of a flat tlre.
The emergency devlce 10 18 generally U-~haped comprlslng a palr of support arms 12 and 14, each arm lncludlng a ~762~?~
bottom section 16 defining a socket C-shaped in cross-section for slidably receiving therein a top portion 18 which is provlded wlth a deep and vertically extending slot 20. ~he top portion 18 of each arm is also provided S with longitudlnally arranged equally ~paced openings 22 for receiving a locklng ~crew 24 mounted to the bottom portlon 16 of the arm. The various opening~ 22 deflne a plurality of po~itions allowing to adjust the length of each arm a~ deslred.
The arms 12 and 14 are made of metalllc material having the requlred strength characteristics. Alumlnum alloy~ are preferred.
A wheel as~embly 26 ~upporting the emergency device 10 on the ground surface iB mounted to the lower extremitle~ of the arm~ 12 and 14. More partlcularly, the wheel a~e~bly comDrl~es a top spindle 32 on which are fixed two rubber roller~ 28 and 30 po~ltioned at axially spaced locatlon~. The extremltles of the ~plndle 32 are rotatably mounted ln opening 38 provided on the arms 12 and 14. If desired, bearing~ may be provlded ln the openlngs 38 for frlctlon reductlon.
A bottom ~pindle 33, identlcal ln con~truction to the top spindle 32, 1~ mounted ~o the arm~ 12 and 14, whereby IZ76;~1 the rubber rollers of the ~pindles 32 and 33 are in a mutual frictional driving relation.
A variant of the wheel assembly, designed by the reference numeral 26, is illustrated in Flgure S. The dlfference with the previously dl~cu~sed arrangement resides ln the use of a removable cyllndrical spindle 32 adapted to be engaged by the bicycle wheel for driving the bottom ~pindle 33. The spindle 32 1~ mounted t~ the arms 12 and 14 by mean~ of a bolt 37 using a butterfly nut 39 for ea~y dl~as~embly, allowlng to readlly remove the ~lndle 32 when lt is not de~lred to provlde a drlvlng relatlon between the blcycle wheel and the lower ~plndle 33, A further varlant of the emergency devlce 10 1B
illu~trated ln Figure 2, shown installed on the front fork of a blcycle de~lgnated by the reference numeral 100. For an lmproved ~tabllity a support link 102 1~ provlded between the emergency device 10 and the blcycle fork.
More partlcula~ly, the link 102 comprlse~ an angular bracket 103 havlng a lower extremlty ~ecured to the bolt 24 and an upper end provlded with a C clamp 104 engaging the fork 100. The bracket 103 18 cons~ltuted by two llnk members 150 and 152 mounted to each other by a bolt 154.
By untlghtening the bolt 154, the angular relatlonshlp ~27620~
between the link members 150 and 154 may be varied to suit various bicycle frame configurations.
Figure 3 illustrates in detail the structure of the C-clamp 104. It comprise~ a block of metallic material 106 provided with a centrally extending tapped bore 108 receivlng a bolt 110. A hook-llke member 112 is plvotally mounted to the block 106 by the lntermedlary of an elonyated hlnge 114.
The operation of the emergency device 10 is as follow~. In ca~e of a flat tlre, the emergency devlce 10 i~ mounted on the fork carrylng the damaged wheel by removing the nut~ retalnlng the wheel axle to the fork and ~llppln~ the wheel axle end~ lnto the re~pectlve slots 20 of the arm~ 12 and 14. The nuts are then tlghtened with the requlred torque ~o a~ to prevent accldcntal rotatlon of the cmergency ~upportlng device 10 wlth re~pect to the fork 100.
When de#lred to provlde a more ~ecure engagement between ~he emergency ~upportlng devlce 10 and the fork of the bicycle, the embodiment lllu~trated in Flgure 2 can be used. In thl~ ca~e, a supportlng arm 102 i~ provided between each of the arms 12 and 14 and the fork 100 by locking the lower extremlty of the angle bracket 103 to 12762Q~
g the ar~ 12 or 14 by means of the bolt 24 and clamping the respective fork between the C-clamp 104 and the bracket 103. Thi~ i~ achieved slmply by locating the hook-like member 112 behind the fork and tightening the bolt 110 to achieve the clamping action.
The length of each arm 12 and 14 iY adjusted by locatlng the bolt 24 ln the proper hole 22 so that the tlre of the blcycle wheel firmly engage~ the top spindl~
32, between the rubber rollers 28 and 30.
The blcycle can be operated ln a normal fa~hion with the emergency device ln~talled. When the latter ls used to ~upport the front wheel of the blcycle, the latter wlll rotate as the blcycle advances due to the driving relatlonshlp exl~tlng between the wheel a~sembly 26 and the blcycle wheel, allowlng to transfer a braklny actlon exerted on the front blcycle wheel to the wheel assembly o~ the e~eryency devlce. In other words, the braklng ~y~tem on the front wheel of the blcycle remalns operatlonal.
When the emergency devlce 1~ u~ed wlth the rear wheel of the blcycle, as lllustrated in Figure 4, the drlvlng relatlonshlp created wlth the wheel assembly of the e~ergency devlce serves a dual purpose. Flr~tly, lt lZ76Z~l allows the bicycle to be propelled ln a normal fashion, by driving the wheel assembly by means of the rear wheel of the bicycle. Secondly, it allow~ to retain the braking capabill~y on the rear wheel of the bicycle.
It should be understood that the above description of the present lnvention i~ not to be interpreted in any llmltlng manner slnce it has been glven only as an example. Various refinements and modlficatlons are po~sible to the one skilled in the art wlthout departing ~rom the ~plrlt of the inventlon. The SCOpQ of the lnventlon 1~ deflned ln the annexed clalm~.
