Abstract

The support for simultaneous changing of the longitudinal position and inclination of the bicycle seat provides mountain bikers to take a more balanced position during riding uphill and thus to overcome technically more demanding sections than they would normally do. The new feature of this mechanism is that it enables the changing of the inclination and shift of the seat during cycling itself. This is enabled also by a remote control with the help of a lever on the handlebar. It consists from an upper part (1) and a lower part (2) which are mutually linked via an axial mechanism (3). The selection of the required position of the seating support is adjusted by the remote control handle (11) which is via a twisted wire (8) which runs along the Bowden cable (9) attached to the handle (10) releasing the conical pin (4) which is located beneath the spring (5) pressed into one of the recesses (6). The prestressing screw (7) adjusts the rigidity of the spring (5).

Description

OPORA ZA SOČASNO SPREMINJANJE VZDOLŽNE LEGE IN NAGIBA KOLESARSKEGA SEDEŽASupport for simultaneous change of the longitudinal position and the inclination of the bicycle seat

Predmet izuma je opora za sočasno spreminjanje vzdolžne lege in nagiba kolesarskega sedeža, ki omogoča spreminjanje položaja sedeža med vožnjo samo.The object of the invention is a support for the simultaneous change of the longitudinal position and tilt of the bicycle seat, which allows changing the position of the seat while driving alone.

Tehnični problem, ki ga rešuje izum omogoča potencialno lažje premagovanje strmih gorsko kolesarskih vzponov in posledično doseganje večje mehanske učinkovitosti.The technical problem solved by the invention makes it easier to overcome steep mountain bike climbs and, consequently, to achieve greater mechanical efficiency.

Inovacija je tako imenovana opora za sočasno spreminjanje vzdolžne lege in nagiba kolesarskega sedeža, ki omogoča gorskemu kolesaiju, da prevozi tehnično zahtevne in strme vzpone z manj naprezanja in večjo mehansko učinkovitostjo. Gorski kolesarji se pri premagovanju strmih vzponov srečujejo s problemom, ki jih nemalokrat prisili v sestop. Namreč, ko se kolo nagne skladno z naklonom vzpona, prične kolesar zaradi sile gravitacije nehote drseti po sedežu nazaj in tako večino telesne teže prenese na zadnje kolo in ni več uravnotežen. Sprednje kolo začne dvigovati in kolesar ni več stabilen ter okreten in je prisiljen sestopiti. Tudi sila s katero lahko kolesar v tem položaju pritiska na pedala je veliko manjša, kot sicer kadar je uravnotežen. Z nagibom sedeža in premikom težišča naprej, katerega omogoča naša inovacija, onemogočimo, da bi kolesar zlezel po sedežu nazaj in ga obdržimo v uravnoteženem položaju ter omogočimo, da kolesar z veliko večjo silo pritiska na pedala. S tem ukrepom prispevamo k večji mehanski učinkovitosti in boljši ekonomičnost pri vožnji v klanec.The innovation is the so-called support for simultaneous change of the longitudinal position and inclination of the bicycle seat, which allows the mountain bike to transport technically demanding and steep climbs with less stress and greater mechanical efficiency. Mountain bikers face a problem that often forces them to descend when overcoming steep climbs. Namely, when the bicycle tilts in accordance with the incline of the incline, due to the force of gravity, the rider starts to accidentally slide backwards on the seat, thus transferring most of his body weight to the rear wheel and no longer balance. The front wheel starts to lift and the rider is no longer stable and agile and is forced to step down. Also, the force with which the rider can press the pedals in this position is much less than otherwise when balanced. By tilting the seat and shifting the center of gravity forward, which is enabled by our innovation, we prevent the rider from sliding across the seat back and keep him in a balanced position and allow the rider to press the pedals with much greater force. This measure contributes to greater mechanical efficiency and better economy when driving uphill.

Do sedaj znane sedežne opore za nastavljanje položaja sedeža med vožnjo so namenjene le spuščanju in zviševanju sedeža, kar pride v poštev pri spustih, ko kolesar želi hitro in enostavno mižati sedež. Tovrstne sedežne onore na ne omoaočaio snrememh v kotil sedeža in premiku naprej. Obstajajo tudi opore, ki služijo kot amortizer za bolj udobno vožnjo, vendar spet v prvi vrsti le za spuste. Reference za zgoraj omenjene sedežne opore:Previously known seat supports for adjusting the position of the seat while driving are intended only for lowering and raising the seat, which is useful for descents when the rider wants to move the seat quickly and easily. Such seating toors do not omoaočaio snrememh into the boiler of the seat and move forward. There are also supports that serve as shock absorbers for a more comfortable ride, but again, primarily for descents. References to the above-mentioned seat supports:

Izum, za katerega želimo pridobiti patent je opora za sočasno spreminjanje vzdolžne lege in nagiba kolesarskega sedeža, ki omogoča pregib in postavitev sedeža v ugoden položaj pri premagovanju strmega vzpona. V oporo vgrajen osni mehanizem omogoča premikanje okoli prečne osi, s čimer spreminjamo tudi nagibni kot sedeža.The invention for which we wish to obtain a patent is a support for the simultaneous change of the longitudinal position and inclination of the bicycle seat, which enables the seat to be folded and positioned in a favorable position when overcoming a steep incline. The axial mechanism built into the support allows it to be moved about the transverse axis, thereby changing the tilting angle of the seat.

Izum je sestavljen iz zgornjega dela(l) in spodnjega (2) dela opore, ki ju povezuje osni mehanizem (3) in omogoča premikanje zgornjega dela (1) v smeri naprej. Spodnji del (2) je fiksiran v okvir kolesa. Konusni zatič (4) z vzmetjo (5) pritiska na konusne reže(6), ki so na vrhu spodnjega dela (2). Prednapetostni vijak(7) uravnava trdoto vzmeti(5). Pletenica (8), ki je preko bovdena (9) speljana do ročke na krmilu (11) za oddaljen nadzor. Ko se pletenico (8) potegne, se preko ročice (lO)konični zatič (4) sprosti in lahko prestavi v drugo vboklino (6) ter postavi zgornji del (1) v drug položaj. Na zgornji del (2) se pritrdi poljubni sedež (12).The invention consists of an upper part (l) and a lower (2) part of the support, which is connected by an axial mechanism (3) and allows the upper part (1) to be moved in a forward direction. The lower part (2) is fixed to the wheel frame. The tapered pin (4) with the spring (5) presses on the tapered slots (6) that are at the top of the lower part (2). The prestressing screw (7) adjusts the spring hardness (5). A braid (8) which is guided through the boom (9) to a handle on the rudder (11) for remote control. When the braid (8) is pulled, the conical pin (4) is released via the lever (10) and can be moved to another recess (6) and the upper part (1) is repositioned. An optional seat (12) is attached to the upper part (2).
