Description

Anordning for svingning av sammenfoldbare lukedeksler. Device for swinging foldable hatch covers.

Oppfinnelsen vedrører en anordning til bruk mellom lukelemmer ved sammenfoldbare lukedeksler for skip. Oppfinnelsen er naturligvis ikke begrenset til anvendelse utelukkende i forbindelse med skip, idet den naturligvis også kan anvendes for lukeåpninger, f. eks. i jernbanevogner, transportvogner og lignende. The invention relates to a device for use between hatch members in collapsible hatch covers for ships. The invention is of course not limited to use exclusively in connection with ships, as it can of course also be used for hatch openings, e.g. in railway wagons, transport wagons and the like.

Egnede sammenfoldbare lukedeksler hvor et hjulvognarrange-ment kan brukes ved manøvreringen er beskrevet i patent nr. 112.480 Suitable collapsible hatch covers where a wheeled trolley arrangement can be used for maneuvering are described in patent no. 112,480

og i patent nr. 115.464.and in patent no. 115,464.

Ifølge oppfinnelsen er det tilveiebragt en anordning ved lukedeksler hvor to sammenstøtende rektangulære lukelemmer er svingbart forbundet med på motstående lukekarmer bevegelige vogner eller lignende og er hengselforbundet med hverandre, slik at lemmene samtidig kan svinges opp til vertikal stilling på vognene med oversiden mot hverandre ved hjelp av en på lemmene virkende kraft. Det som kjennetegner anordningen er at der i den eller de i området mellom vognene og uavhengig av lemmenes svingeforbindelser med vognene anbragte hengselforbindelser mellom lemmene er innskutt et stivt kraft-overførende ledd, hvilket ledd kan overføre krefter fra den ene lukelem til den andre på en slik måte at en svingebevegelse av den ene lukelem relativt vognen bevirker en svingebevegelse av den andre lukelem om dens svingeforbindelse med vognen, idet svingekraften kommer til virkning i hengselforbindelsen. • According to the invention, a device has been provided for hatch covers where two colliding rectangular hatch members are pivotally connected to carriages or the like moving on opposite hatch frames and are hinged to each other, so that the limbs can simultaneously be swung up to a vertical position on the carriages with the upper side towards each other by means of a force acting on the limbs. What characterizes the device is that a rigid force-transmitting joint is inserted into the hinged joints between the limbs located in the area between the carriages and independent of the limbs' swing connections with the carriages, which joint can transmit forces from one hatch member to the other in such a way way that a swinging movement of one hatch member relative to the carriage causes a swinging movement of the other hatch member about its swing connection with the carriage, as the swing force comes into effect in the hinge connection. •

Oppfinnelsen skal forklares nærmere under henvisning til tegningene hvor fig. 1 viser et sideriss av et foretrukket utførel-seseksempel, og fig. 2 viser et planriss. The invention will be explained in more detail with reference to the drawings where fig. 1 shows a side view of a preferred embodiment, and fig. 2 shows a plan view.

Tegningene viser en leddforbindelse mellom to hosliggende lukelemmer, hvilke i fig. 1 er vist i lukket stilling med stiplede linjer og i delvis sammenfoldet stilling ved hjelp av fullt opptrukne linjer. The drawings show a joint connection between two adjacent hatch members, which in fig. 1 is shown in the closed position with dashed lines and in the partially folded position with solid lines.

Selve vognen har henvisningstallet 246 og består av en ram-me 248 hvori et par hjul 25O og 251 er roterbart lagret for samvirke med en skinne 252. Skinnen 252 er anordnet på en lukekarm 42 slik at vognen kan beveges på karmen. Lukelemmen 158 er svingbart forbundet med vognrammen 248 ved hjelp av en forbindelsesbolt 254»og lukelemmen 2l6 er svingbart forbundet med vognrammen 248 ved hjelp av en bolt 256. Et kraftoverførende ledd 258 er svingbart forbundet med sine endedeler til utragende deler 260 og 262 på lukelemmene 158 og 2l6 ved hjelp av bolter 264, resp. 266. Den spesielle geometri i anordningen av det kraftoverførende ledd 258 med hensyn til svingefor-bindelsene 254 og 256 mellom lemmene I58 og 216 og vognrammen 248 er slik at den danner et firestengers leddarrangement, slik at en svingebevegelse av lemmen 158 vil frembringe nedadrettet kraft i leddet 258, hvi.lken kraft frembringer et moment om hengself orbindelsen 256 til lemmen 216. Dette firestengers leddarrangement er slik at det kraft-overførende ledd 258 vil utgjøre drivanordningen for lemmen 216 på grunn av den riktige geometriske anordning av leddet i forhold til lukelemmenes svingepunkter på vognrammen. Det er anordnet en vogn på hver side av lukelemmene. The carriage itself has the reference number 246 and consists of a frame 248 in which a pair of wheels 250 and 251 are rotatably stored for cooperation with a rail 252. The rail 252 is arranged on a hatch frame 42 so that the carriage can be moved on the frame. The hatch member 158 is pivotally connected to the carriage frame 248 by means of a connecting bolt 254 and the hatch member 216 is pivotally connected to the carriage frame 248 by means of a bolt 256. A power transmitting link 258 is pivotally connected with its end parts to projecting parts 260 and 262 on the hatch members 158 and 2l6 by means of bolts 264, resp. 266. The special geometry in the arrangement of the power-transmitting link 258 with regard to the pivoting connections 254 and 256 between the limbs I58 and 216 and the carriage frame 248 is such that it forms a four-bar joint arrangement, so that a pivoting movement of the limb 158 will produce a downward force in the joint 258, which force produces a moment about the hinge connection 256 to the limb 216. This four-bar joint arrangement is such that the force-transmitting joint 258 will constitute the drive device for the limb 216 due to the correct geometrical arrangement of the joint in relation to the hinge points of the hatch limbs on the carriage frame. A carriage is arranged on each side of the hatch members.

Vognarrangementet kan brukes mellom den andre og tredje lukelem i et trelems lukedeksel eller mellom den andre og tredje lukelem i et lukedeksel med fire lemmer, og tilsvarende kan vognarrangementet. anordnes mellom tilsvarende ytterligere lukelempar. Det ønske-de lukelemarrangement er naturligvis avhengig av og bestemmes av dBn The carriage arrangement can be used between the second and third hatch members in a three-member hatch cover or between the second and third hatch members in a four-member hatch cover, and similarly the carriage arrangement can. are arranged between corresponding additional hatch members. The desired slot element arrangement naturally depends on and is determined by dBn

spesielle lukeåpning som skal tildekkes.special hatch openings to be covered.

Under sammenfoldingen av lukelemmene vil løftingen av lemmen I58 ved hjelp av egnede innretninger (ikke vist) overføre en kraft gjennom leddet 258, og det vil tilveiebringes et moment rundt svingepunktet 256 til lemmen 216, slik at lemmen 216 svinger om for-bindelsen 256. Der hvor det brukes et lukelempar vil kraftoverfør-ingsleddet 258 virke som en hjelp til drivsystemet mellom hosliggende lukelemmer i hvert lukelempar under sammenfoldingen av lukelemmene. During the folding of the hatch limbs, the lifting of the limb I58 by means of suitable devices (not shown) will transfer a force through the joint 258, and a torque will be provided around the pivot point 256 of the limb 216, so that the limb 216 swings about the connection 256. There where a hatch limb is used, the power transmission link 258 will act as an aid to the drive system between adjacent hatch limbs in each hatch limb during the folding of the hatch limbs.

Når lukeåpningen skal lukkes, beveger vognen seg i den mot-satte retning hvorved lukedekslet foldes ut til lukket stilling. Det kraftoverførende ledd 258 begrenser lukkingen av en tredje lukelem 2l6 i det tilfelle hvor man har et lukedeksel med tre lukelemmer i avhengighet av bevegelsen til lukelemmen 158. When the hatch opening is to be closed, the carriage moves in the opposite direction whereby the hatch cover unfolds to the closed position. The power-transmitting link 258 limits the closing of a third hatch member 216 in the case where one has a hatch cover with three hatch members depending on the movement of the hatch member 158.

Som før nevnt kan vognarrangementet benyttes i forbindelse med slike lukedekselsystem og manøvreringsanordninger som er vist og beskrevet i norsk patent nr. 112.480 og norsk patent nr. 115.464- As previously mentioned, the carriage arrangement can be used in connection with such hatch cover systems and maneuvering devices as are shown and described in Norwegian patent no. 112,480 and Norwegian patent no. 115,464-
