Description

LAS MED REGLINGSANORDNING TEKNISKT OMRADE FOreliggande uppfinning avser ett las for en fordonsdOrr for forsvarande eller forhindrande av inbrott och overfall av personer som befinner sig i fordonet. Laset skall vara svart att forcera fran utsidan av fordonet och är speciellt avsett att regla/sparra en i och for sig kand lasmekanism sa att denna inte kan oppnas fran utsidan utan hjalp av en person som befinner sig inne i fordonet. Uppfinningen är framst avsedd for tyngre/kommersiella fordon sasom lastbilar och liknande men kan naturligtvis aven anvandas i andra fordon med lasbara dorrar sasom exempelvis personbilar, entreprenadmaskiner etc. Uppfinningen avser aven ett fordon forsett med ett dorrlas enligt uppfinningen. TECHNICAL FIELD The present invention relates to a lock for a vehicle door for defending or preventing burglary and assault of persons present in the vehicle. The load must be black to force from the outside of the vehicle and is especially intended to lock / lock a per se known welding mechanism so that this can not be opened from the outside without the help of a person who is inside the vehicle. The invention is primarily intended for heavier / commercial vehicles such as trucks and the like, but can of course also be used in other vehicles with weldable doors such as, for example, passenger cars, construction machinery, etc. The invention also relates to a vehicle provided with a door load according to the invention.

TEKNIKENS BAKGRUND De fiesta pA marknaden forekommande fordon är forsedda med lasbara dorrar for att forhindra inbrott och stalder. Manga dorrlas är dock for den initierade relativt enkla att utan omfattande Atgarder manipulera sa att dorren kan Oppnas utifran utan nyckel. Detta är betydande problem dA det blir alit vanligare med inbrott i fordonen och inte minst att sovande forare overrumplas och ranas. Risken for overfall och ran, och aven kapning av fordon, maste minimeras. BACKGROUND ART Most vehicles on the market are equipped with lockable doors to prevent burglary and stalls. However, many door locks are relatively easy for the initiate to manipulate without extensive Atgarder, so that the door can be opened from the outside without a key. This is a significant problem as it is becoming more and more common with burglary in the vehicles and not least that sleeping drivers are surprised and robbed. The risk of assault and robbery, and also hijacking of vehicles, must be minimized.

Forarna viii alltsa garna kunna lasa dorren fran insidan av fordonet pa ett satt som inte är majligt eller atminstone är svart att manipulera fran utsidan. Samtidigt är det viktigt att laset är enkelt att hantera for foraren, t.ex. vid en kris- eller olyckssituation. Ett problem som kan uppsta am ett separat las anordnas som är placerat pa sidan av fordonets ordinarie las och som inte manovreras med hjalp av ordinarie Oppningshandtag är att det kan forsvara utrymning ur fordonet t.ex. i en paniksituation dl sikten i hytten av nag-at skdl kan vara begrdnsad, t.ex. vid marker eller brand. Vid sAdana paniksituationer är det vanligt att fbraren forsaker bppna dbrren pA det invanda vanliga sdttet och kan i hastigheten missa att ett separat sdkerhetslas är aktiverat/lAst. FOr att eliminera risken for sddana mbjligen fatala misstag är det onskvdrt att fordonet alltid kan Oppnas med det vanliga, ordinarie, oppningshandtaget. The drivers will therefore be able to lock the door from the inside of the vehicle in a way that is not possible or at least black to manipulate from the outside. At the same time, it is important that the load is easy to handle for the driver, e.g. in a crisis or accident situation. A problem that can arise if a separate lock is arranged which is placed on the side of the vehicle's ordinary lock and which is not maneuvered with the aid of ordinary opening handles is that it can justify evacuation from the vehicle e.g. in a panic situation dl the view in the cabin of nag-at skdl may be limited, e.g. in case of fields or fire. In such panic situations, it is common for the driver to try to open the doors in the usual way and may quickly miss that a separate safety lock is activated / locked. To eliminate the risk of such potentially fatal mistakes, it is undesirable that the vehicle can always be opened with the usual, ordinary, opening handle.

Manga forsbk har gjorts att lbsa detta inbrottsproblem. Exempelvis har dorrarna ferstdrkts genom att skyddsplAtar monterats for att tdcka ldsets komponenter men det har dndd visat sig svart att gbra en sdker ldsinstallation som kan Oppnas pd vanligt sdtt med dorrens ordinarie bppningshandtag. Many attempts have been made to solve this burglary problem. For example, the doors have been reinforced by fitting protective plates to cover the components of the door, but it has turned out to be black to make a secure door installation that can be opened in the usual way with the door's regular opening handle.

Nackdelarna med kdnda losningar är att ldsen alltsd inte Or tillrdckligt sdkra och effektiva. Kdnd teknik visar inte nAgon ldskonstruktion som fbregriper foreliggande uppfinning och som pd ett effektivt, funktionellt och kostnadseffektivt sdtt bidrar till att sdkerstdlla en lasfunktion som ger Onskad sdkerhet for fordonets forare. The disadvantages of cold solutions are that the solution is not sufficiently safe and effective. The prior art does not disclose any wheel construction which embodies the present invention and which in an efficient, functional and cost-effective manner contributes to ensuring a load function which provides undesired safety to the driver of the vehicle.

SAMMANFATTNING AV UPPFINNINGEN Syftet med uppfinningen är att losa ovan ndmnda problem och att pdvisa en ldskonstruktion vars mekanism fbrhindrar eller betydligt forsvdrar ett obnskat intrdng i fordonet genom att fordonets dorrlds manipuleras och Oppnas utifrAn utan medverk- an av en person som vistas inne i fordonet. SUMMARY OF THE INVENTION The object of the invention is to solve the above-mentioned problems and to demonstrate a rail construction whose mechanism prevents or significantly impedes an unwanted entry into the vehicle by manipulating the vehicle door and opening it from the outside without the participation of a person staying inside the vehicle.

Ett ytterligare dndamAl med uppfinningen Or att mekanismen i ldset skall samverka med dOrrens inre bppningshandtag for att fbrenkla ldsning och uppldsning sd att inga ytterligare manoverhandtag skall behova hanteras fer att bppna dorren. A further object of the invention is that the mechanism in the lock should co-operate with the inner opening handle of the door to facilitate loading and unloading so that no additional control handles need to be handled before opening the door.

Ett ytterligare andamal med uppfinningen är att laskonstruktionen skall kunna lasas och lasas upp genom att endast manovrera dorrens vanliga oppningshandtag sa att en snabb och saker upplasning skall kunna utforas. A further object of the invention is that the welding construction should be able to be read and unloaded by only maneuvering the door's usual opening handle so that a quick and things unloading can be performed.

Ett ytterligare andamal med uppfinningen är att mekanismen som forhindrar eller forsvarar manipulation av laset utifran skall samverka med rerliga delar i laset. A further object of the invention is that the mechanism which prevents or defends manipulation of the laser from the outside should co-operate with movable parts in the laser.

Ett ytterligare andamal med uppfinningen är att befintliga las skall kunna kompletteras sa att en laskonstruktion enligt uppfinningen uppnas. A further object of the invention is that existing welds can be supplemented so that a weld construction according to the invention is achieved.

Ett ytterligare andamal med uppfinningen är att laskonstruk- tionen skall vara enkel och funktionell till sin konstruktion, best a av sa fa delar som mojligt och latt kunna byggas in dagens produkt/fordon utan omfattande modifieringar av hyttstomme eller paneldetaljer. A further object of the invention is that the welding construction should be simple and functional in its construction, consisting of as few parts as possible and easy to build into today's product / vehicle without extensive modifications of cab body or panel details.

Ett ytterligare andamal med uppfinningen är att laskonstruktionen skall vara enkel att montera sa att tillverkningen kan ske snabbt och kostnadseffektivt. A further object of the invention is that the welding structure should be easy to assemble so that the manufacture can take place quickly and cost-effectively.

Dessa och ytterligare andamal och fordelar uppnas enligt upp25 finningen genom en anordning definierad av de sardrag som anges i den kannetecknande delen av det sjalvstandiga patentkravet 1. These and further objects and advantages are achieved according to the invention by a device defined by the features set forth in the characterizing part of the independent claim 1.

Uppfinningen är som namnts framst avsedd for tyngre kommersi- ella fordon sasom lastbilar och liknande men kan naturligtvis aven anvandas for andra typer av fordon dar inbrotts- eller overfallsrisk foreligger pa grund av att dorrlaset kan manipuleras fran fordonets utsida. As mentioned above, the invention is primarily intended for heavier commercial vehicles such as trucks and the like, but can of course also be used for other types of vehicles where there is a risk of burglary or assault due to the fact that the door load can be manipulated from the outside of the vehicle.

Uppfinningen uppnas dels genom att anordna en kapsling eller platkapa pi lasets utsida, dvs. att en extra plat med till dorren anpassad form placeras mellan ldset och dorrens yttre plat eller dorrens yttre plastdetaljer, dels en mekanism som aktivt reglar/fixerar laset i lasets spdrrade ldge. The invention is achieved partly by arranging an enclosure or plate cut on the outside of the weld, i.e. that an extra plate with a shape adapted to the door is placed between the door set and the door's outer plate or the door's outer plastic details, and a mechanism that actively regulates / fixes the lock in the locked width of the door.

Kapslingen är utformad sd att den tdcker/avskarmar ldsets vdsentliga och rorliga delar sett fran dorrens utsida exempelvis om flagon forsaker nd ldset genom att borra eller pi annat satt ta sig genom dorrens yttre stalplat. Kapslingen bestir ldmpligen av en stalplat av sadan tjocklek eller platkvalitet att den är svdr att forcera med en normal borrmaskin. The enclosure is designed so that it covers / shields the essential and movable parts of the door seen from the outside of the door, for example if flakes cause the door by drilling or otherwise getting through the outer steel plate of the door. The housing typically consists of a steel plate of such thickness or plate quality that it is difficult to force with a normal drilling machine.

Reglingen bestir av ett rerligt, t.ex. vrid- eller ledbart, reglingsorgan sdsom t.ex. en hake som kan gd i ingrepp med en rorlig del, en lasarm, i ett i och for sig }cant las i det lage derren är list pa normalt sdtt, dvs. di anvdndaren aktiverat dorrens ldssparr frdn insidan. Reglingsorganet pdverkas via en drags-tang med en lastapp anordnad i dorren exempelvis upptill i ndrheten av sidorutan och ndra derrens bakre stolpe. Ndr ldstappen befinner sig i sitt byre uppstickande andlage är reglingen i laset inte aktiverad och nar lastappen tryckts ned till sitt nedre andldge är reglingen i laset aktiverad. The regulation consists of a real, e.g. rotatable or articulated, regulating means such as e.g. a hook that can be engaged with a movable part, a laser arm, in a per se} cant las in the low derren is a list in the normal way, ie. The user has activated the door's latch from the inside. The control means is actuated via a drawbar with a load pin arranged in the door, for example at the top near the side window and change the rear post of the door. When the load pin is in its overhanging abutment, the control in the lock is not activated and when the load pin is pressed down to its lower end, the control in the lock is activated.

Den uppfinningsenliga losningen medfOr att laset manOvreras frdn fordonets insida genom att en lastapp vid sidorutan manovreras. Oppningshandtaget pi dorrens insida manovreras allts6 pi normalt satt och dras inat av fararen nar darren skall oppnas. I ett forsta moment frigors reglingsorganet, dvs haken vrids undan fran sitt reglingsldge och frigor lasarmen. I ett andra moment manovreras lasarmen. Lastappen vid sidorutan forskjuts uppat samtidigt som haken frigors fran lasarmen. The unloading according to the invention means that the load is maneuvered from the inside of the vehicle by maneuvering a load pin at the side window. The opening handle on the inside of the door is thus maneuvered in the normal way and pulled inwards by the operator when the door is to be opened. In a first step, the control member is released, ie the hook is turned away from its control lever and releases the laser arm. In a second step, the laser arm is maneuvered. The loading pin at the side window is displaced upwards at the same time as the hook is released from the loading arm.

Genom att anvanda en separat reglingsanordning i laset forhindras alltsd att ldsmekanismen i det ordinarie liset kan paverkas utifran och risken for ett oonskat intrang I fordonet fOrsvaras/forhindras och en hOgre sakerhet uppnas. By using a separate control device in the load, the locking mechanism in the ordinary lock can be prevented from being affected from the outside and the risk of an unwanted intrusion into the vehicle is defended / prevented and a higher level of safety is achieved.

Den uppfinningsenliga losningen kraver inte nagra fOrandringar i den befintliga laskonstruktionen vilket medfor att det ar forhallandevis latt, och clamed kostnadseffektivt, att implementera den nya lOsningen i produktionskedjan for nytillverkning av fordon. Uppfinningen gor det av samma skal latt att uppgradera las pa redan tillverkade fordon. 10 Ytterligare sardrag och fordelar med uppfinningen framgar av den foljande, mer detaljerade, beskrivningen av uppfinningen samt av bifogade ritningar och ovriga patentkrav. The solution according to the invention does not require any changes in the existing load construction, which means that it is relatively easy, and claimed to be cost-effective, to implement the new solution in the production chain for new production of vehicles. For the same purpose, the invention makes it easy to upgrade readings on already manufactured vehicles. Further features and advantages of the invention will become apparent from the following, more detailed description of the invention, and from the accompanying drawings and other claims.

Lasarmen 16 Or anordnad att rora sig i vertikal riktning och laset 4 befinner sig i last lage nOr lasarmen 16 Or i sitt byre andlage (som i figuren). Nar lasarmen 16 befinner sig i ett nedre andlage Or laset 4 ()last. Figure 6 shows, for the sake of safety, a view of the welding construction, seen from the rear edge of the door, and the parts included in the welding construction and the laser arm 16 important for the invention are provided with a welding eye 17, but have exposed from the other components of the door 1. The laser arm 16 Or is arranged to move in the vertical direction and the laser 4 is located in the load position when the laser arm 16 Or is in its upper abutment (as in the figure). When the laser arm 16 is in a lower abutment Or the laser 4 () load.

Figur 7 slutligen Askddliggor laset 4 och dess ingdende delar mer i detalj och hur den uppfinningsenliga kompletterande reglingsmekanismen gar i ingrepp med den i och for sip kdnda lasarmen 16, och narmare bestamt hur ett hakelement 18 kan vridas in i lAsarmens 16 lAsegla 17. Uppfinningen innefattar ants& ett hakelement 18 ledat kring en forsta axel 19. Hakelementet 18 ar anordnat att pa i ingrepp med lasoglan 17 anordnad i den del av laset 4 som reglar eller reglar upp dess lAsfunktion med hjdlp av t.ex. en nyckel. Vajern 13 är anordnad att pdverka ldsmekanismen via en havarm 25 som kan forskjutas mellan tre olika lagen. Havarmen 25 laser laset 4 nar den ror sip till ett inre andlage A, dvs nar den ror sip axiellt ldngst At hager i figuren 7. I ett mellanldge B, som Or default-lage dit havarmen 25 atergdr automatiskt, nar vajern 13 Or opaverkad och slutligen i ett yttre andlage C paverkar havarmen 25 lasets bppningsfunktion att oppna samtidigt som en upplasningsarm 20, via en klack 21, vrids kring sin axel 22. Uppldsningsarmen 20 pdverkar hakelementet 18, via en rulle 23, att vridas medsols kring axeln 19 och haken 18 vrids ddrmed ur ingreppet med lasoglan 17. Samtidigt trycks dragstangen 14 uppat eftersom den är ledad i rullen 23 och i hakelementet 18. Darmed Or lasarmen 16 mojlig att fOrskjuta till sitt nedre andlage och laset 4 Or mojligt att oppna pa normalt satt, bade fran insidan av dorren 1 och med nyckel fran utsidan av dorren 1. Figure 7 finally shows the laser 4 and its constituent parts in more detail and how the additional control mechanism according to the invention engages with the laser arm 16 known in and for example, and more specifically how a hook element 18 can be turned into the laser sail 17 of the laser arm 16. The invention comprises A hook element 18 is hinged around a first axis 19. The hook element 18 is arranged to engage with the laser eye 17 arranged in the part of the laser 4 which regulates or regulates its laser function by means of e.g. a key. The wire 13 is arranged to actuate the load mechanism via a sea arm 25 which can be displaced between three different layers. The sea arm 25 is laser lased 4 when it moves sip to an inner abutment A, i.e. when it moves sip axially longest At hager in figure 7. In an intermediate bed B, which Or default-lay where the sea arm 25 returns automatically, when the wire 13 Or unaffected and finally, in an outer abutment C, the lever arm 25 causes the opening function of the lock to open at the same time as a loading arm 20, via a lug 21, is rotated about its axis 22. The lifting arm 20 causes the hook element 18, via a roller 23, to rotate clockwise about the shaft 19 and the hook 18 At the same time, the drawbar 14 is pushed upwards because it is articulated in the roller 23 and in the hook element 18. This makes it possible for the laser arm 16 to move to its lower face and the latch 4. It is possible to open in the normal way, both from the inside of the door 1 and with a key from the outside of the door 1.

Vid regling av laset 4 trycks dragstangen 14 manuellt ned mot verkan av en platt och bojd fjader 24 och hakelementet 18 vrids in i lasarmens 16 lasogla 17. Detta Or endast mojligt att gOra nar ldset 4 redan befinner sip i last ldge, dvs nar lasarmen 16 Or i sitt byre andlage. Detta kan astadkommas pa tva satt. Det ena Or att laset 4 lases med nyckel utifran och det andra Or att spdrrhandtaget pa dorrens insida (ej visat), dvs. vid det inre dorrOppningshandtaget, manOvreras sd att havarmen 25 med hjalp av vajern 13 forskjuts till sitt inre andlage A, dvs. at hoger i figuren. When adjusting the latch 4, the drawbar 14 is manually pressed down against the action of a flat and curved spring 24 and the hook element 18 is rotated into the laser eye 17 of the laser arm 16. This is only possible when the load set 4 is already in load, ie when the laser arm 16 Or in his byre andlage. This can be accomplished in two ways. One is that the lock 4 is locked with a key from the outside and the other is that the locking handle on the inside of the door (not shown), ie. at the inner door opening handle, it is operated so that the sea arm 25 with the aid of the wire 13 is displaced to its inner abutment A, i.e. that hooks in the figure.
