Var och en av hjulaxlarna 27 ãr ovridbart lagrad i ett pa fjadern medelst skruvar 30 fastsatt lager 31 (fig. 4). As can be seen from Fig. 13, the collapsible headboard 3 has a generally edge stroke and comprises a bottom frame 6 supporting one seat, the sides of the bottom frame projecting, collapsible side post 7, a footrest 8, a backrest 9 and the seat, side post and the backrest connecting upholstery 10. The bottom frame 6 consists of a rigid frame with two spaced spaced, parallel, longitudinal side frame portions 11, a longitudinal center frame portion 12 and two. the spirits of the side frame parts 11 connecting cross pieces 13. At each of the side frames 11 of each side frame part Oro rotatably mounted two. Side support parts 14, which are hingedly connected to an armrest 15 connecting the upper spirits of the side support members 14 and together with this form the side support 7. Saval footrest is the backrest 9, which rear crosspiece 13 and foldable in the longitudinal direction of the yacht. For holding the footrest and the backrest in striking position, Oro arranged two. pa sidostOden 14 pivotally mounted stirrups 16 resp. 17, on whose transverse parts 18 and 19 the footrest 8 resp. the backrest 9 in the yagn of the use vim. The foldable handle 4 supported by the upper gear 3 is formed on a handle bracket 20, the shins of which are connected to their lower spirits by means of guide members 21. showed lasorgan Oro fastlaslas with said holders. For attachment of the Oyerredet 3 1 striking layer, there is an upwater, spring-loaded welding bracket 23, the transverse part of which extends below the bottom frame and the shins of the eye. which are mounted on the front side support members 14. The side projecting pins 24 are engaged. The handle Or, as shown in Fig. 1, is releasably and articulatedly connected to the side post 7 by means of a longitudinal connection 25 arranged on either side of the carriage, which connects the holder 22 to the armrest 15 and consists of two articulated and mutually weldable links, which allow the adjustment of the handle 4 from the forward-facing layer shown in Fig. 1 to a rearward-facing bearing for flipping the carriage from behind. The chassis 2, which carried the collapsible upper chassis 3, comprises a longitudinal leaf spring 26 arranged on each side of the carriage, wheel axles 27 fixed on the leaf springs, means for connecting the chassis to the collapsible chassis and the above-mentioned connecting parts 5. the wheel axles. The leaf springs 26, which in their respective spirits extend upwards in a bag, are connected to the bottom frame 6 by means of hatred straps 28, which are threaded through a halo in the outer, free spirits of the leaf springs and of the projections 13 outside the side frame parts 11 projecting. The leaf springs are further connected to the bottom frame by means of a loading strap 29 arranged on each side of the carriage, which is received by a ring fixed at approximately the middle of the side frame part 11 and a holding member panned on the leaf spring. Each of the wheel axles 27 is non-rotatably mounted in a bearing 31 fixed to the spring by means of screws 30 (Fig. 4).

Vid den visade utforingsformen besta forbindningsdelarna 5 av distanshylsor, som aro tradda pa de inre andarna av hjulaxlarna 27 samt forsedda med lasorgan for fastlasning av hylsorna pa sagda hjulaxlar. Sasom tydligt visas i fig. 4 besta lasorganen av pa. var sin ande av hylsan anbragta, vridbart lagrade bladfjaderformiga sparrar 32, vilka vardera aro forsedda med en tapp 33, som i laslage skjuter genom ett hal 34 i hylsan samt ingriper med ett periferiellt, ringformigt spar axeln. In the embodiment shown, the connecting parts 5 consist of spacer sleeves which are threaded on the inner spirits of the wheel axles 27 and provided with welding means for welding the sleeves to said wheel axles. As clearly shown in Fig. 4, the welding means consist of pa. rotatably mounted leaf spring-shaped rafters 32, each of which is provided by the sleeve, are each provided with a pin 33 which, in welding, projects through a hole 34 in the sleeve and engages with a peripheral, annular spar shaft.

Hopfallningen av vagnen sker pa. foljande salt: Sedan lasbygeln 23 och lankfarbindningen 25 hragts ur laslage, fallas sidostaden 7 samtidigt med handtaget 4 framat och nediit, varefter fotsttidet och ryggstodet fallas in och handtagsbygeln 20 falles bakat. Darefter borttogas forbindningsdelarna 5 genom att sparren 32 upplyftes och svanges over at endera sidan, varigenom tappen 33 frigares fran sitt ingrepp med sparet 35, sa att fOrbindningsdelen kan dragas bort fran axelanden. Hjulen kunna nu svangas in under averredet 3 samt lampligen fastlasas i detta lage medelst en rem, som spannes om fjadrarna silsom visas i fig. 3. Till foljd av att forbindningsdelarna 5 Aro direkt forbundna med hjulaxlarna erhalles en mycket enkel, tilltalande och stabil konstruktion. The collapse of the carriage takes place on. following salt: After the welding bracket 23 and the langfarb binding 25 have been pulled out of the welding layer, the side post 7 is dropped simultaneously with the handle 4 forwards and downwards, after which the footrest and the backrest are folded in and the handle bracket 20 is dropped backwards. Thereafter, the connecting parts 5 are removed by lifting the raft 32 and pivoting over either side, whereby the pin 33 is released from its engagement with the raft 35, so that the connecting part can be pulled away from the shaft ends. The wheels can now be pivoted under the avertebrate 3 and suitably welded in this layer by means of a strap, which is tensioned about the springs screened in Fig. 3. As a result of the connecting parts 5 being directly connected to the wheel axles, a very simple, attractive and stable construction is obtained.
