Opfindelsen angår en snaplås navnlig til lukning af et vindue, en dør eller lignende, omfattende en basisdel, en til forskydning fra en lukkestilling, mod en fjederkraft indrettet falde med en fremspringende del 5 for indgreb med et slutblik samt et manøvreorgan til at føre falden til en tilbagetrukket åbnestilling, hvor falden også er drejelig i forhold til basisdelen omkring en akse på tværs af retningen for nævnte forskydning, åbnestillingen er en om nævnte akse uddrejet 10 stilling, og der findes et fjedrende organ til at holde falden i en ikke uddrejet stilling parallelt med lukkestillingen.The invention relates to a snap lock, in particular for closing a window, door or the like, comprising a base part, one for displacement from a closing position, against a spring force arranged with a projecting part 5 for engagement with a final look and a maneuvering means for leading the falls to a retracted opening position, wherein the drop is also rotatable relative to the base portion about an axis transverse to the direction of said offset, the opening position is a pivoted position about said axis, and there is a resilient means for holding the drop in a non-extended position in parallel with the closing position.

En sådan snaplås kendes fra DE-fremlæggelses-skrift nr. 1 021 750, som beskriver en lås til en køle-15 skabsdør.Such a snap-lock is known from DE-presenting specification No. 1 021 750, which describes a lock for a refrigerator door.

Pra DE-brugsmønster nr. 71 28 377.7 kendes en snaplås ved brug af hvilken det er muligt at lukke eksempelvis en vindue ved at smække det i, hvorved vinduet låses, forstået på den måde at snaplåsen skal udlø-20 ses aktivt, før vinduet kan åbnes igen.Pra DE usage pattern no. 71 28 377.7 discloses a snap lock by means of which it is possible to close, for example, a window by slamming it in, thereby locking the window, understood in the way that the snap lock must be actively released before the window can opens again.

Undertiden er det ønskeligt at eksempelvis et vindue kan lukkes aktivt mod et pakningstryk ved hjælp af låsen og i andre tilfælde vil det være ønskeligt at en snaplås kan inaktiveres, således at vinduet ikke 25 låses, hvis det smækkes i.Sometimes it is desirable, for example, to open a window actively against a packing pressure by means of the lock and in other cases it is desirable that a snap lock can be deactivated so that the window will not lock if it is slammed into.

Formålet med opfindelsen er at tilvejebringe en snaplås som opfylder de ovennævnte krav.The object of the invention is to provide a snap lock which meets the above requirements.

Dette opfyldes ved hjælp af en snaplås af den indledningsvis anførte art som er særegen ved, at fal-30 den og basisdelen udgør modstående elementer i en fir-leddet mekanisme, idet falden ved sin ene, den fremspringende del omfattende ende ved hjælp af et første hængsel er hængslet til et lænkeled som igen ved hjælp af et andet hængsel er hængslet til basisdelen, falden 35 ved sin anden ende ved hjælp af et tredje hængsel er hængslet til manøvreorganet, som igen ved hjælp af et DK 168406 B1 2 fjerde hængsel er hængslet til basisdelen, og de fire hængslers akser i det væsentlige er indbyrdes parallelle. Herved opnås, at snaplåsen ud over at virke som almindelig snaplås, dels kan lukke et vindue aktivt mod 5 et pakningstryk ved drejning af falden fra den uddrejede åbnestilling til lukkestillingen, idet det fjedrende organ forhindrer snaplåsen i uønsket at springe op, dels kan inaktiveres således, at vinduet eller døren kan lukkes uden at blive låst.This is accomplished by means of a snap-lock of the kind initially provided, which is peculiar in that the trap and base portion constitute opposing elements of a four-joint mechanism, the drop at one end of which protruding part by means of a first hinge is hinged to a link hinge which is again hinged to the base by means of a second hinge, the drop 35 at its other end by a third hinge is hinged to the actuator, which in turn is hinged by a fourth hinge. to the base, and the axes of the four hinges are substantially parallel to one another. This results in that the snap lock, in addition to acting as a regular snap lock, can partly close a window actively against a packing pressure by rotating the drop from the extended opening position to the closing position, the resilient means preventing the snap lock from undesirably opening and partly inactivating it. , that the window or door can be closed without being locked.

10 I en udførelsesform omfatter det tredje hængsel en hængseltap, som i den ene af falden og manøvreorganet er lejret i et langhul, der strækker sig i retningen for nævnte forskydning, når falden er i lukkestillingen. Langhullet sikrer muligheden for faldens for-15 skydning.In one embodiment, the third hinge comprises a hinge pin which, in one of the traps and the actuator, is housed in a long hole extending in the direction of said displacement when the trap is in the closing position. The long hole ensures the possibility of the fall offset.

I en yderligere udførelsesform er den firledede mekanisme således dimensioneret, at det første, andet og fjerde hængsel i et plan vinkelret på hængselakserne danner en stump vinkel, når falden er i lukkestil-20 lingen, og en spids vinkel, når falden er i åbenstillingen. Herved opnås at falden ved nævnte forskydning i det væsentlige parallelforskydes.In a further embodiment, the four-way mechanism is dimensioned such that the first, second and fourth hinges in a plane perpendicular to the hinge axes form a blunt angle when the fall is in the closing position and a pointed angle when the fall is in the open position. Hereby, the decrease in said displacement is substantially paralleled.

I en videre udførelsesform omfatter snaplåsen et stop, der er således indrettet, at det tredje, 25 første og andet hængsel i et plan vinkelret på hængsel- 0 0 akserne danner en stump vinkel mindre end 180 , nar falden er i åbnestillingen. Herved opnås at snaplåsen ikke er selvlåsende i åbnestillingen.In a further embodiment, the snap lock comprises a stop so arranged that the third, first and second hinges in a plane perpendicular to the hinges 0 form a blunt angle less than 180 when the fall is in the open position. This ensures that the snap lock is not self-locking in the open position.

Endvidere er falden i en udførelsesform udformet 30 i det væsentlige som et L, hvor det første hængsel befinder sig forved L'ets knæk, og det tredje hængsel befinder sig for enden af L'ets lange ben, L'ets korte ben strækker sig væk fra basisdelen og ved sin fjerne ende omfatter en anlægsflade til indgreb med slutblik-35 ket, når falden er i lukkestillingen, og det tilsigtede angrebspunkt for anlægsfladen, det første og det andet DK 168406 B1 3 hængsel i et plan vinkelret på hængselakserne danner en stump vinkel, der er konkav i forhold til den øvrige del af den firledede mekanisme, og den tilsigtede angrebsretning i angrebspunktet i det væsentlige svarer 5 til retningen fra angrebspunktet mod det første hængsel, når falden er i lukkestillingen. Herved opnås, at snaplåsen er selvlåsende i lukkestillingen.Further, in one embodiment, the drop is formed essentially as an L, where the first hinge is adjacent to the L's crack and the third hinge is at the end of the L's long leg, the L's short leg extending away from the base portion and at its distal end a contact surface for engagement with the final look when the fall is in the closing position and the intended point of attack of the contact surface, the first and second hinges in a plane perpendicular to the hinge axes form a blunt angle concave with respect to the other part of the four-way mechanism, and the intended direction of attack at the point of attack substantially corresponds to the direction from the point of attack to the first hinge when the fall is in the closing position. This ensures that the snap lock is self-locking in the closing position.

I en yderligere udførelsesform har basiselementet en anlægsflade for montering og en ydre afgrænsning 10 nær det andet hængsel, lænkeleddet har en i forhold til den firledede mekanisme udvendig flade som, når falden er i lukkestillingen, strækker sig fra nævnte ydre afgrænsning af basiselementet i det væsentlige vinkelret på dettes anlægsflade og gennem en bøjning væk fra den 15 øvrige del af den firledede mekanisme til nærheden af det første hængsel. Herved udgør nævnte udvendige flade en anslagsflade for slutblikket, når et vindue monteret med snaplåsen ifølge opfindelsen smækkes i, hvorved lænkeleddet virker som en vægtarm og tvinger falden 20 tilbage mod fjederkraften, idet nævnte bøjning sikrer, at lænkeleddets vægtarm fra det andet hængsel til slut-blikkets anslagspunkt får en tilstrækkelig størrelse til at sikre en pålidelig virkning.In a further embodiment, the base member has an abutment surface for mounting and an outer boundary 10 near the second hinge, the link member having an outer surface relative to the four-way mechanism, which, when the drop is in the closing position, extends substantially from said outer boundary of the base element. perpendicular to its abutment surface and through a bend away from the other 15 of the four-member mechanism to the proximity of the first hinge. Hereby said outer surface forms an impact surface for the final look when a window mounted with the snap lock according to the invention is slammed in, whereby the link joint acts as a weight arm and forces the fall 20 back against the spring force, said bending ensuring that the link arm's weight arm from the second hinge to the end. the gaze's impact point is of sufficient size to ensure a reliable effect.

Det fjedrende organ påvirker fortrinsvis manøv-25 reorganet i retning væk fra åbnestillingen for derved at kunne holde falden i den ikke uddrejede stilling.The resilient means preferably affects the actuator in a direction away from the open position so as to be able to keep the fall in the non-turned position.

I en yderligere udførelsesform omfatter snaplåsen et andet fjedrende organ til at holde falden i åbnestillingen, hvorved lænkeleddet kan omfatte en knast 30 som, når falden er i åbnestillingen, samvirker med det andet fjedrende organ for at holde falden i åbnestillingen. Derved opnås at snaplåsen kan inaktiveres således, at vinduet ikke låses, hvis det smækkes i.In a further embodiment, the snap lock comprises a second resilient means for holding the drop in the open position, whereby the link joint may comprise a cam 30 which, when the drop is in the open position, cooperates with the second resilient member to keep the drop in the open position. This results in that the snap lock can be deactivated so that the window does not lock if it is slammed into.

Opfindelsen vil i det følgende blive forklaret 35 nærmere ved hjælp af et udførelseseksempel under henvisning til tegningen, på hvilken DK 168406 B1 4 fig. 1 viser et snit gennem en snaplås ifølge opfindelsen monteret på eksempelvis en vinduesramme, fig. 2 viser et billede set i retning af pilen II i fig. 1, og 5 fig. 3 et billede svarende til fig. 1 men med snaplåsen i åbnestillingen.The invention will now be explained in more detail by way of an embodiment with reference to the drawing, in which FIG. 1 shows a section through a snap lock according to the invention mounted on, for example, a window frame; FIG. 2 shows a view in the direction of arrow II in FIG. 1 and 5 in FIG. 3 is a view similar to FIG. 1 but with the snap lock in the open position.

Snaplåsen er i fig. 2 vist selvstændigt, medens den i fig. 1 er vist monteret i en vinduesramme 1, som ved hjælp af en pakning 2 er tætnet mod en karm 3.The snap lock is shown in FIG. 2 independently, while the one shown in FIG. 1 is shown mounted in a window frame 1 which is sealed to a frame 3 by means of a gasket 2.

10 På karmen 3 er monteret et slutblikelement 4 til indgreb med snaplåsen.10 On the frame 3 is mounted a final plate element 4 for engagement with the snap lock.

Selve snaplåsen omfatter en falde 5 med en rulle 6, der er monteret drejelig omkring en akse vinkelret på tegningens plan. Falden 5 er ved hjælp 15 af en første hængseltap 7 hængslet til et lænkeled 8, som igen ved hjælp af en anden hængseltap 9 er hængslet til en basisdel 10.The snap lock itself comprises a drop 5 with a roller 6 mounted pivotally about an axis perpendicular to the plane of the drawing. The trap 5 is hinged to a link link 8 by means of a first hinge pin 7, which in turn is hinged to a base part 10 by means of a second hinge pin 9.

Falden 5 er endvidere ved hjælp af en tredje hængseltap 11 hængslet til et manøvreelement 12, 20 som igen ved hjælp af en fjerde hængseltap 13 er hængslet til basisdelen 10. Denne har mod vinduesrammen 1 en anlægs flade 14 ud fra hvilken, der strækker sig et par hule ben 15 op i hvilke, der kan skrues skruer for montering af snaplåsen på vinduesrammen 25 1.Furthermore, the trap 5 is hinged to a maneuvering element 12, by means of a third hinge pin 11, which in turn is hinged to the base part 10 by means of a fourth hinge pin 13, which has against the window frame 1 an abutment surface 14 from which extends a pair of hollow legs 15 up into which screws can be screwed for mounting the snap lock on the window frame 25 1.

Manøvreelementet 12 er forsynet med et håndtag i form af en profilstang 16, som strækker sig i retning vinkelret på tegningens plan. Manøvreelementet 12 er endvidere forsynet med et langhul 17, hvori den 30 tredje hængseltap 11 er lejret. Hængseltappen 11 holdes ved hjælp af en trykfjeder 18 i anlæg mod langhullet 17's, set i fig. 1, venstre side. Endvidere er manøvreelementet 12 ved hjælp af en skruefjeder 19 belastet i retning mod uret set i fig. 1 og 3.The maneuvering element 12 is provided with a handle in the form of a profile rod 16 which extends in a direction perpendicular to the plane of the drawing. The maneuvering element 12 is further provided with a long hole 17 in which the third hinge pin 11 is mounted. The hinge pin 11 is held by means of a compression spring 18 against the longhole 17's, as seen in FIG. 1, left side. Furthermore, the actuating element 12 is loaded by means of a screw spring 19 in a counterclockwise direction as seen in FIG. 1 and 3.

35 Når snaplåsen ifølge opfindelsen anvendes som almindelig snaplås, dvs. når vinduesrammen 1 smækkes DK 168406 B1 5 i, vil vinduesrammen 1 passere hen over slutblikele-mentet 4 og det samme vil en del af lænkeleddet 8. Dette har en flade 20, som efter en bøjning skråner i forhold til et plan vinkelret på vinduesrammen l's 5 plan, i retning mod slutblikket 4, som har en tilsvarende skrå flade 21. Den skrå del af fladen 20 vil ramme den skrå flade 21 og blive presset væk fra slut-blikelementet 4, hvorved lænkeleddet 8 virker som en vægtarm og via den første hængseltap 7 presser 10 falden 5 væk fra slutblikelementet 4. Dette er muligt fordi den tredje hængseltap 11 bevæger sig i langhullet 17 mod kraften fra trykfjederen 18. Når såvel lænkeleddet 8 som rullen 6 har passeret den skrå flade 21, vil falden 5 vende tilbage til den i 15 fig. 1 viste lukkestilling, hvorved rullen 6 indgriber med en låseflade 22 på slutblikelementet 4 og låser vinduesrammen 1.When the snap lock according to the invention is used as ordinary snap lock, i.e. when the window frame 1 is slammed in, the window frame 1 will pass over the final sheet element 4 and so will a part of the link joint 8. This has a surface 20 which, after a bend, slopes relative to a plane perpendicular to the window frame 1's. 5, towards the final look 4, which has a corresponding inclined face 21. The inclined portion of the face 20 will hit the inclined face 21 and be pushed away from the end gaze member 4, whereby the linkage member 8 acts as a weight arm and via the first hinge pin 7 pushes the trap 5 away from the final sight element 4. This is possible because the third hinge pin 11 moves in the long hole 17 against the force of the compression spring 18. When both the link joint 8 and the roller 6 have passed the inclined surface 21, the trap 5 will return to the one shown in FIG. 1, the roller 6 engages with a locking surface 22 on the end plate element 4 and locks the window frame 1.

Når vinduet skal åbnes, føres falden 5 til en åbnestilling ved at manøvreelementet 12 ved hjælp af 20 håndtaget 16 drejes i retning med uret set i fig. l og 3 omkring den fjerde hængseltap 13.When the window is to be opened, the trap 5 is brought to an open position by turning the actuating element 12 by means of the handle 16 in a clockwise direction as seen in FIG. 1 and 3 around the fourth hinge pin 13.

Snaplåsen vil herved indtage den i fig. 3 viste åbnestilling som afgrænses af, at lænkeleddet 8 slår imod et stop 23. Skruefjederen 19 vil ved sin på-25 virkning af manøvreelementet 12 i retning mod uret søge at føre snaplåsen tilbage til den i fig. 1 viste stilling, men skruefjederen 19 er ikke kraftig nok til at overvinde et indgreb mellem en fjedrende tunge 24 på basisdelen 10 og en knast 25 på lænkeleddet 30 8, hvorfor snaplåsen kan forblive i den i fig. 3 viste åbnestilling. Ved hjælp af håndtaget 15, kan en person imidlertid bringe snaplåsen tilbage til den i fig.The snap-lock will thereby occupy the one shown in FIG. 3, which is defined by the linking link 8 beating against a stop 23. In its action of the actuating element 12 in the counterclockwise direction, the coil spring 19 will attempt to return the snap lock to the one shown in FIG. 1, but the coil spring 19 is not strong enough to overcome an engagement between a resilient tongue 24 on the base member 10 and a cam 25 on the link joint 30 8, so the snap lock may remain in the one shown in FIG. 3. However, by means of the handle 15, a person can return the snap lock to the one shown in FIG.

1 viste lukkestilling. Herved vil rullen 6's centrum i det væsentlige følge den med stiplet linie viste bane 35 26 og det ses heraf, at snaplåsen er i stand til at lukke vinduet aktivt og derved tilvejebringe et pakningstryk mod pakningen 2.1. Hereby, the center of the roller 6 will substantially follow the path 35 26 shown in dotted line, and it can be seen that the snap-lock is able to close the window actively and thereby provide a gasket pressure against the gasket 2.

Af hensyn til snaplåsens gode virkning er en række geometriske og mekaniske krav opfyldt. Således befinder aksen for den første hængseltap 7 sig i fig. l til venstre for forbindelseslinien mellem aksen 5 for rullen 6 og aksen for den anden hængseltap 9. Herved sikres det, at snaplåsen er selvlåsende i lukkestillingen. Endvidere ses det, at akserne for den første, den tredje og den fjerde hængseltap i den i fig. l viste lukkestilling befinder sig på en i det væ-10 sentlige ret linie. Når snaplåsen virker som almindelig snaplås, ved at vinduesrammen 1 smækkes, vil aksen for den tredje hængseltap komme til at ligge ovenfor forbindelseslinien mellem den første og den fjerde hængseltap, og der vil derfor optræde et moment, som 15 søger at dreje manøvreelementet 12 i retning med uret, hvorved snaplåsen ville blive åbnet. Denne drejning modvirkes imidlertid af skruefjederen 19 ved en passende afstemning af denne fjeders styrke i forhold til styrken af trykfjederen 18. Endelig er stoppet 20 23 således indrettet at det sikres, at aksen for den første hængseltap 7, som set i fig. 3 altid befinder sig oven. for forbindelseslinien mellem den anden hængseltap 9 og den tredje hængseltap 11. Herved sikres det, at snaplåsen ikke låser sig selv i åbnestillingen, 25 men altid manuelt kan bringes tilbage til lukkestillingen.For the good effect of the snap lock, a number of geometric and mechanical requirements have been met. Thus, the axis of the first hinge pin 7 is in FIG. 1 to the left of the connecting line between the axis 5 of the roller 6 and the axis of the second hinge pin 9. This ensures that the snap lock is self-locking in the closing position. Furthermore, it is seen that the axes of the first, third and fourth hinge pins of the one shown in FIG. 1, the closing position shown is on a substantially straight line. When the snap lock acts as a regular snap lock by slamming the window frame 1, the axis of the third hinge pin will be above the connecting line between the first and the fourth hinge pin, and a torque will then occur which seeks to rotate the maneuver element 12 in the direction. clockwise, thereby opening the snap lock. However, this rotation is counteracted by the coil spring 19 by an appropriate adjustment of the strength of this spring relative to the strength of the compression spring 18. Finally, the stop 20 23 is arranged to ensure that the axis of the first hinge pin 7, as seen in FIG. 3 is always on top. for the connection line between the second hinge pin 9 and the third hinge pin 11. This ensures that the snap lock does not lock itself in the open position, but can always be manually returned to the closing position.
