Sperre for låseanordning ved semmenfellbare barnevognerLock for locking device for folding prams
Description
Foreliggende oppfinnelse vedrdrer en sperre for låseanordning ved sammenfellbare barnevogner, hvilken låseanordning innbefatter en låsering som for å hindre utilsiktet sammenfelling skyves over to langstrakte vogndeler som ved sammenfelling av vognen flytter seg fra hverandre. The present invention relates to a locking device for collapsible prams, which locking device includes a locking ring which, in order to prevent accidental folding, is pushed over two elongated parts of the carriage which move apart when the carriage is folded.
Ved sammenfellbare barnevogner må utilsiktet sammenfelling hindres ved hjelp av låseorganer, hvorav et flertall typer er kjent. Da barnevogner (spesielt sittévogner) av forskjellige In the case of collapsible prams, accidental folding must be prevented by means of locking devices, of which a majority of types are known. Then prams (especially prams) of different types
fabrikat sammenfelles på i hovedsaken samme måte,, nemlig ved at hånd--takdelen felles fremad ag nedad samtidig som en i hovedsaken X-formet rammes ben felles sammen, og da låse anordn ingens konstruksjon er be-tinget, av sammenfellingsmåten, dominerer en type av låseanordninger sterkt. Denne låseanordning innbefatter en på hvert håndtaksben anordnet låsering med en storre innerdiarneter enn håndtaksbenenes ytterdiarneter. Da den nedre del av håndtakets ben er leddbart forbundet med barnevognens ramme på sådan måte, at de med håndtaksbenens forbundne rammedeler og håndtaksbenene lbper parallelt med hverandre i barnevognens oppfeldte stillingmen befinner seg i vinkel med hverandre i dens sammenfelte stilling, vil ringene i vognens oppfeldte stilling ved sin egen tyngde gli nedad langs håndtaksbenene og om- manufacture is folded together in essentially the same way, namely by the handle part folding forward and downwards at the same time as the legs of an essentially X-shaped frame are folded together, and then the locking device's construction is conditioned, by the folding method, a type dominates of locking devices strongly. This locking device includes a locking ring arranged on each handle leg with a larger inner diameter than the outer diameter of the handle legs. Since the lower part of the leg of the handle is hingedly connected to the frame of the pram in such a way that the frame parts connected to the handle leg and the handle legs are parallel to each other in the folded position of the pram but are at an angle to each other in the folded position, the rings in the folded position of the pram will by its own weight slide down along the handle legs and around
slutte såvel benene som de med disse parallelle rammedeler, hvorved sammenfelling av vognen hindres. A/ed tilsiktet sammenfelling av barnevognen loftes bare de to låseringer over leddpunktet mellom håndtaksbenene og rammedelene, hvoretter håndtaket uten hindring kan felles fremad og vognen felles sammen. join the legs as well as those with these parallel frame parts, whereby collapsing of the carriage is prevented. A/ed intentional folding of the pram, only the two locking rings are lifted above the joint point between the handle legs and the frame parts, after which the handle can be folded forward without hindrance and the pram can be folded together.
Ovennevnte låsering er særlig fordelaktig da den erThe above locking ring is particularly advantageous as it is
enkel å fremstille, enkel å manovrere og virker automatisk ved vog-nensoppfelling. easy to manufacture, easy to maneuver and works automatically when the vehicle is parked.
Imidlertid har det vist seg at under uheldige omstendig-heter kan barnet som sitter i vognen selv lofte de to ringer, hvilket medforer en av barnets egen tyngde forårsaket umiddelbar sammenfelling av vognen. En viss, om enn liten, risiko finnes også for at ringene ved rystelser eller på annen måte kan bringes ut av sin låsende stil-lin g. However, it has been shown that under unfortunate circumstances the child sitting in the pram can lift the two rings themselves, which causes one of the child's own weight to collapse the pram immediately. There is also a certain, albeit small, risk that the rings can be moved out of their locking style by shaking or in some other way.
Det er således dnskelig å tilveiebringe en sperreanordning som hindrer utilsiktet forflytning av låseringen fra dens låsende stilling. En slik sperre må tilfredsstille et antall krav, It is thus desirable to provide a locking device which prevents accidental movement of the locking ring from its locking position. Such a lock must satisfy a number of requirements,
blant annet må den være lett å bringe i og ut av funksjon, være vanske-lig å lose for et barn, ikke få forringet virkning ved flittig an-vendelse, ikke vesentlig fordyre produktet samt være slik utformet at det er lett å se om sperren er i funksjon eller ikke. among other things, it must be easy to bring in and out of function, be difficult to loosen for a child, not be impaired by frequent use, not significantly increase the price of the product and be designed in such a way that it is easy to see whether the latch is in operation or not.
Et formål med foreliggende oppfinnelse er å tilveiebringe en sperreanordning som oppfyller de ovennevnte krav. An object of the present invention is to provide a locking device which meets the above-mentioned requirements.
Denne oppgave er ifolge oppfinnelsen hovedsakelig lost ved at en sperre av den innledningsvis beskrevne type er gitt de kj.ennetegn.. at den. omfatter e.t„ a.rgan ..soni.er bevegelig.. anbragt på minst...... .den ene av de langstrakte vogndeler for omstilling av partier av organet i hovedsakelig rett vinkel med vogndelene mellom en fdrste og en annen stilling, i hvilke stillinger et av partiene strekker seg inn i låseringens bevegelsesbane og hindrer flytting av låseringen forbi organet. According to the invention, this task is mainly solved by the fact that a barrier of the type described at the outset is given the characteristics... that it. comprises e.t„ a.rgan ..soni.is movable.. placed on at least...... .one of the elongate carriage parts for repositioning parts of the organ at substantially right angles with the carriage parts between a first and another position, in which positions one of the parts extends into the movement path of the locking ring and prevents movement of the locking ring past the body.
En foretrukket utforelseform av sperren ifolge oppfinnelsen kjennetegnes ved at organet er hovedsakelig triangelformet, at dets ene hjorne er svingbart forbundet med minst den ene av de langstrakte vogndeler og at organets to dvrige hjdrner danner nevnte partier og er beliggende på forskjellig avstand fra det fdrstnevnte hjorne. A preferred embodiment of the barrier according to the invention is characterized by the fact that the body is mainly triangular, that one of its corners is pivotally connected to at least one of the elongate carriage parts and that the two opposite corners of the body form said parts and are located at different distances from the first-mentioned corner.
Oppfinnelsen skal i det folgende beskrives nærmere under henvisning til tegningen på hvilken fig. 1 viser skjematisk et barnevognsunderstell av den aktuelle type i oppfeldt stilling og fig. 2 under sammenfelling mens fig. 3 viser i storre målestokk for-bindelsesstedet mellom håndtaket og understellet med sperren ifolge oppfinnelsen. The invention will be described in more detail in the following with reference to the drawing in which fig. 1 schematically shows a pram undercarriage of the type in question in the folded position and fig. 2 during folding while fig. 3 shows on a larger scale the connection point between the handle and the chassis with the latch according to the invention.
Den på fig. 1 og 2 skjematisk viste barnevogn er av konvensjonell type og omfatter et håndtak 1, som er U-formet med benene vendt nedad, og ved disses nedre ender finnes ledd 2 som forbinder håndtaksbenene med flattjern 3, som ved den annen ende bærer vognens forreste hjulaksel.

På fig.1 og 2 vises også en låsering 8, som konvensjo-nelt er anordnet rundt håndtakets 1 ben og glidbar langs benene mellom en forste, låsende stilling (fig. 1) og en annen ikke låsende stilling (fig. 2). Fortrinnsvis er håndtakets begge ben forsynt med hver sin låsering 8.

The locking member 9 is pivotable between a front, a rear and an intermediate position and the fit is such that a certain force is necessary for the organ to swing. In all of these three positions, the locking device prevents movement of the locking ring B upwards (and downwards) past the locking device, as either its front, rear or both corners protrude into the locking ring's path of movement.
For å muliggjøre flytting av låseringen forbi sperreorganet må dette forst trykkes bakover, således at dets forreste hjorne flyttes ut av låseringens bevegelsesbane hvoretter ringen kan flyttes oppad inntil den ligger an mot' sperreorganets bakre hjorne. To enable movement of the locking ring past the locking device, this must first be pushed backwards, so that its front corner is moved out of the locking ring's path of movement, after which the ring can be moved upwards until it rests against the locking device's rear corner.
Med låseringen i denne stilling må deretter sperreorganet skyves fremad således at dets bakre hjorne flyttes ut av ringens bevegelsesbane. Heretter kan låseringen fores fritt oppad langs håndtaksbenet. Sam- With the locking ring in this position, the locking member must then be pushed forward so that its rear corner is moved out of the ring's path of movement. The locking ring can then be fed freely upwards along the handle leg. Sam-
me manøvrering gjentas omvendt ved nedforing av låseringen til låsende stilling. me maneuver is repeated in reverse when lowering the locking ring to the locking position.
Sperreorganet 9 kan fremstilles på en enkel måte og f.eks. bestå av en utstanset platedetalj, eller en passende tykk, triangelformet boyet ståltråd. Sperreorganet er videre hensiktsmessig ytstyrt med en form av fremspring som samvirker med håndtaksbenet for å definere organets forskjellige stillinger. The locking member 9 can be produced in a simple way and e.g. consist of a punched plate detail, or a suitably thick, triangular bent steel wire. The locking member is further suitably equipped with a form of projection which cooperates with the handle leg to define the various positions of the member.
Sperren ifolge oppfinnelsen er enkel å manovrere forThe barrier according to the invention is easy to manoeuvre
en voksen, men hindrer effektivt barnet i å skyve låseringen ut av den låsende stilling. Sperren har i virkeligheten vist seg så -effektiv at det er helt tilstrekkelig å anbringe den ved barnevognens ene side. an adult, but effectively prevents the child from pushing the locking ring out of the locking position. In reality, the barrier has proven so effective that it is completely sufficient to place it on one side of the pram.
