CLASS I NTERNAT I ON ELLSVENSK B 62 j63g: 3 PATENT AND REGISTRATION AGENCY Ans. 207/1962 on 9/1 1962To a drawing PK OLSEN, NYKOBING, DENMARK Bicycle saddle with drop-hard front piece The invention relates to a bicycle saddle with a drop-down front piece, which is rotatably mounted on a fixed stand, with the help of which the saddle can be attached to the bike rack .

Det liar tidigare foreslagits att utforma en cykelsadel med ett nedfallbart framstycke och ett likaledes nedfallbart ryggstod, sâ att sadeln darigcnom kan anpassas individuellt efter cyklisten eller dennes kladsel. Exempelvis ãr det vid vanliga eykelsadlar en olagenhet, att kvinnor iforda en snav kjol ha svart for att sitta ph sadeln pa grund av kjolens langd och darfor ofta maste stalla sig upp pa pedalerna, varigenom korningen blir vinglig och osaker. Vid den kanda eykelsadeln med nedfallbart framstycke och nedfallbart ryggstod aro dessa svangbara delar emellertid endast inskjutna i sadelpinnen och aro darfor Overhuvud taget ej fjadrande, varfor de ej folja rorelserna hos sadelns mittdel, vilken i regel har god fjadring. Vidare fir det vid den kanda sadeln en olagenhet, att mittdelen och framstycket 1 dettas uppfallda 'age ej ligga tatt in-till varandra, och att an skrnvnyckel maste anvandas for att lossa framstycket frail sadelpinnen och delvis utdraga det ur denna, innan nedfallning kan ske. Detta arbete fir besvarligt, och dessutom orsaka mellanrummet mellan framstycket och mittstycket samt skruven for fasthallning air framstycket I uppsvangt lfige, att risk finnes for att cyklistens klader skola fastna i sadelns delar och sanderriva s. It has previously been proposed to design a bicycle saddle with a collapsible front piece and a similarly collapsible backrest, so that the saddle can thereby be individually adapted to the cyclist or his upholstery. For example, in the case of ordinary eykels saddles, it is an anomaly that women wearing a tight skirt have black to sit on the saddle due to the length of the skirt and therefore often have to stand on the pedals, whereby the grain becomes shaky and unsafe. In the case of the well-known eykels saddle with a collapsible front piece and a collapsible backrest, however, these pivotable parts are only inserted into the seat post and are therefore not resilient at all, so they do not follow the movements of the middle part of the saddle, which usually has good suspension. Furthermore, in the case of the known saddle, there is a disadvantage that the middle part and the front piece 1 have not fallen into each other, and that a wrench must be used to loosen the front piece from the seat pin and partially pull it out of it, before falling down. . This work is responsible, and also causes the space between the front piece and the middle piece and the screw for holding the front piece in a suspended position, that there is a risk that the cyclist's clothes will get stuck in the parts of the saddle and sand rips.

Andamalet med uppfinningen är att astadkomma en cykelsadel med ett nedffillbart framstycke, som i uppfallt late ãr fjadrande att det foljer rorelserna hos sadeln i ovrigt. Framstycket skall fiven vara sit anbragt, att dess overdrag tillsammans med ovriga delen av sadeliiverdraget bildar en sammanhangande yta. Vidare skall framstycket kunna fasthallas i sitt lage utan anvandning av utskjutande delar och skall kunna fallas upp och ned endast genom ett enkelt grepp om detsamma. Detta uppnas enligt uppfinningen darigenom, att cykelsadeln bestar av ett främre och ett bakre barstycke, vilka hada firo vridbart lagrade pa. det fasta stiklet omkring en gemensam axel, som ar vinkelrat mot sadelns langdriktning. De hada barstyckena uppbara vardera en -vid sadelns framre resp. bakre ande vridbart lagrad och i vridningsriktningen fjaderpaverkad vipparm, och dessa vipparmar stracka sig Mat mot sadelns mitt pit sadant salt, att de motas i huvudsak ovanfOr barstyckenas gemensanuna vridningsaxel, nar det av det framre barstycket med tillhorande vipparm bestaende framstycket befinner sig i uppsvangt lage, i vilket det Or fastlasbart med hjalp av en snapplasmekanism. Genom denna anordning uppnas, att framstyeket och sadelns av det bakre barstycket med tillhorande vipparm bestaende huvuddel kunna utfOra samtidiga fja.dringsrorelser samt kunna uppbarns av vanliga langsgkende fjadrar understOdda sadeloverdrag, vilka bilda en sammanhangande yta. The object of the invention is to provide a bicycle saddle with a fold-down front piece, which in a striking manner is resilient in that it follows the movements of the saddle in general. The front piece must be fitted so that its cover together with the rest of the saddle cover forms a continuous surface. Furthermore, the front piece must be able to be held in its position without the use of protruding parts and must be able to be folded up and down only by a simple grip on the same. This is achieved according to the invention in that the bicycle saddle consists of a front and a rear bar piece, which had four rotatably mounted on. the fixed stem about a common axis, which is perpendicular to the longitudinal direction of the saddle. The had bar pieces each supported one -at the front resp. rear end rotatably mounted and in the direction of rotation spring-actuated rocker arm, and these rocker arms extend Mat towards the middle pit of the saddle so salt that they are received mainly above the common axis of rotation of the bar pieces, when the front bar piece with associated rocker arm is in raised bearing. in which it Or is weldable by means of a snap-fit mechanism. By means of this device it is achieved that the front piece and the main part of the rear bar piece with associated rocker arm can perform simultaneous suspension movements and can be supported by ordinary longitudinal springs supported saddle covers, which form a continuous surface.

Snapplasmekanismen enligt uppfinningen kan lampligen yam framstalld pa det sattet, att den framre vipparmen vid sin bakre ande är fOrsedd med en nedatriktad tapp, som kan ingripa i ett motsvarande hM i den bakre vipparmens framre ande samt fasthallas i detta med hjalp ay en dragfjfider eller torsionsfjader, som stravar att draga den framre vipparmen ned mot det framre barstycket. Nar framstycket skall fallas ned, utloses det latt genom att vipparmen svanges uppat, varpa det kan vridas neat till vertikalt lage. The snap-fit mechanism according to the invention can suitably be designed in such a way that the front rocker arm at its rear end is provided with a downwardly directed pin, which can engage in a corresponding hM in the front end of the rear rocker arm and be held therein by means of a tension spring or torsion spring. , which strains to pull the front rocker arm down towards the front bar piece. When the front piece is to be lowered, it is easily released by swinging the rocker arm upwards, warping it can be turned neatly to a vertical position.

Enligt uppfinningen kan snapplasmekanismen amen utgoras ay en. vid framstyckets framre ande vridbart lagrad lasstang, som vid sin fria undre ande ar utformad med ett hak, som i framstyckets uppfallda lige kan gripa om en tvargfiende lastapp pa sadelns fasta stod. Lasstangen fir m. a. o. krokt sit att den i framstyckets nedfallda lage kan gripa om lastappen med det krokta partiet. Genom denna mekanism utloses framstycket latt saval fran horisontellt som fran vertikalt lage genom att Dupl. kl. 63 g: 2 '1373O — man med ett finger trycker latt uppat mot den under framstycket anbragta lasstangen. According to the invention, the snapplas mechanism amen can be formed in one. at the front end of the front piece a rotatably mounted load bar, which at its free lower spirit is formed with a hook, which in the striking body of the front piece can grip a transverse enemy load pin on the saddle's fixed stand. The load bar, for example, is crooked so that it can grip the load pin with the crooked part in the lowered layer of the front piece. Through this mechanism, the front piece is easily released from horizontal as well as from vertical position by Dupl. at 63 g: 2 '1373O - press lightly with one finger upwards against the load bar placed under the front piece.

FOr att lasstangen i framstyckets uppfallda lage ej skall hoppa ur sitt ingrepp med lts tappen, kan den pa sin oversida vara forsedd med en utskjutande bladfjader, som är placerad sa, att den i framstyckets uppfallda lage anligger mot undersidan av barstyckenas gemensamma vridningsaxel. In order that the load bar in the raised position of the front piece should not jump out of its engagement with the light pin, it may be provided on its upper side with a projecting leaf spring, which is positioned so that in the raised layer of the front piece abuts against the common axis of rotation of the bar pieces.

Anordningen enligt uppfinningen forklaras narmare under hanvisning till bifogade ritning, som visar en utforingsform av cykelsadein enligt uppfinningen. For tydlighetens skull am dock sadeloverdraget och de detta uppbarande fjadrarna utelamnade. The device according to the invention is explained in more detail with reference to the accompanying drawing, which shows an embodiment of a bicycle saddle according to the invention. For the sake of clarity, however, the saddle cover and the springs this supported were omitted.

SadaIn är forsedd med ett for montering pa cykelstativet avsett stod 14 med tva barstyc: ken 2 och 9, vilka aro vridbart lagrade pa en _gemensam, av stiidet 14 uppburen axeltapp 1. Barstycket 2 har en vipparm 6, som fir lagrad vridbar omkring en axeltapp 7 vid barstyckets framre ande, och det bakre barstycket 9 har en vipparm 12, som är lagrad vridbar omkring en axel 13 vid barstyckets bakre ande. Vid belastning av sadeln kan barstycket 9 vrida sig omkring axeln 1 under hoptryckning av en fjader 15, och samtidigt uppstar fjadring genom att vipparmen 12 vid sin framre ande med hjalp av en fjader 10 stoder mot stiidet 14. The saddle is provided with a stand 14 intended for mounting on the bicycle frame with two bar pieces 2 and 9, which are rotatably mounted on a common shaft pin 1 supported by the stand 14. 7 at the front end of the bar piece, and the rear bar piece 9 has a rocker arm 12, which is mounted rotatably about an axis 13 at the rear end of the bar piece. When the saddle is loaded, the bar piece 9 can rotate about the shaft 1 under compression of a spring 15, and at the same time suspension arises when the rocker arm 12 at its front end with the aid of a spring 10 abuts against the guide 14.

Vid den visade utforingsformen av sadeln enligt uppfinningen ar sakerheten mot nedfanning tvalaldig genom att tvâ snapplasmekanismer aro anordnade, vilka dock bada kunna betjanas samtidigt darigenom, att man med handerna griper om sadelns framstycke. Den ena snapplasmekanismen utgores av den framre vipparmen 6, som av en fja der 11 drages nedat mot barstycket 2 och som vid sin bakre ande uppbar en tapp 16, vilken kan ingripa i ett motsvarande bal i vipparmens 12 framre arida. Vid vipparmens 6 lyftning mot verkan av fjadern 11 kan tappen. 16 fans upp ur halet, sä att den ej hindrar framstyckets vridning. Fjadern 11 kan ev. ersattas med en. omkring axeltappen 7 monterad torsionsfjader. In the embodiment of the saddle shown according to the invention, the safety against folding down is twofold in that two snap-fit mechanisms are provided, which, however, can both be operated simultaneously by gripping the front of the saddle with the hands. One snap mechanism is constituted by the front rocker arm 6, which is pulled downwards towards the bar piece 2 by a spring 11 and which at its rear spirit carries a pin 16, which can engage in a corresponding bale in the front arid of the rocker arm 12. When lifting the rocker arm 6 against the action of the spring 11, the pin can. 16 fans out of the tail, so that it does not prevent the front piece from turning. The spring 11 can ev. replaced by a. torsion spring mounted around the shaft journal 7.

Den andra snapplasmekanisinen utgores av en lasstang 3, som an lagrad vridbar omkring axeltappen 7 och som pa undersidan av sin fria ande Or forsedd med ett hak, vilket i det visade laget griper om en tvargaende lastapp 4 pa stodet 14. For att lasstangen vid eventuella skakningar ej skall hoppa ur sitt ingrepp med lastappen 4, är den pa sin oversida forsedd med en bladfjader 5, som anligger mot axeltappens 1 undersida. Lasmekanismen utlases vid lyftning av lasstangen 3. The second snap-fit mechanism consists of a load rod 3, which is mounted rotatably about the shaft pin 7 and which on the underside of its free spirit Or is provided with a hook, which in the shown layer grips a transverse load pin 4 on the post 14. In order that the load rod at any shaking should not jump out of its engagement with the load pin 4, it is provided on its upper side with a leaf spring 5, which abuts against the underside of the shaft pin 1. The welding mechanism is unloaded when lifting the welding rod 3.

Nar framstycket svanges neat till vertikalt lage, glider lasstangen 3 Over lastappen 4, och i andlaget ingriper en krokt del av lasstangen bakom lastappen 4, sa att framstycket fasthalles i vertikalt lage. When the front piece is not swung neatly to a vertical position, the load bar 3 slides over the load pin 4, and in the abutment a curved part of the load bar engages behind the load pin 4, so that the front piece is held in a vertical position.

Det Er tydligt, att de visade snapplasmekanismerna aro var for sig tillrackliga for att fasthalla framstycket i uppfallt lage. It is clear that the snap-fit mechanisms shown are individually sufficient to hold the front piece in a striking position.
