I Fig. 2 är nospartiet NP has handelen ME i fdrd med att antra dockningsanordningen 1 av hontyp. I Fig. 3 är dockningen fullbordad, dvs. handelen ME är fullgott upptagen i dockningsanordningen 1 av hontyp. Under dockningen fOrskjuts det ladformiga holjet HE i sin langdriktning relativt ramverket FW. Det ladformiga haljet HB forskjuts i framf6rningsriktningen for den elektriska gaffeltrucken T. Farskjutningen av det ladformiga haljet HE till dess slutliga ldge kommer att aktivera en elektrisk stramstdllare ES inuti det ladformiga holjet HB, varvid strOmstallaren ES visas endast schematiskt i Fig. 1-3. Nar salunda det ladformiga haljet HE har forskjutits till sitt slutliga ldge befinner sig den elektriska str6mstallaren ES i operativt lage, dvs. str6m flyter fran kraftkallan PU och genom de elektriska kablarna EC tram till nospartiet NP has handelen ME. Figs. 2 and 3 show schematically how the electric forklift T gradually changes the charging station S. In Fig. 2 the nose portion NP has the trade ME in the process of entering the female type docking device 1. In Fig. 3 the docking is completed, ie. the trade ME is fully occupied in the female-type docking device 1. During docking, the charge-shaped housing HE is displaced in its longitudinal direction relative to the framework FW. The charge-shaped housing HB is displaced in the direction of travel of the electric forklift T. The displacement of the charging-shaped housing HE to its final length will activate an electric tensioner ES inside the charging-shaped housing HB, the current switch ES being shown only schematically in Figs. 1-3. Thus, when the charge-shaped shaft HE has been displaced to its final length, the electric switch ES is in operative position, i.e. current flows from the power source PU and through the electrical cables EC tram to the muzzle NP has the trade ME.

Tva generellt vertikala element 7 (endast ett visas i Fig. 4) stracker sig mellan de horisontella elementen 5, varvid de fyra elementen 5 och 7 bildar holjet 3 has dockningsanordningen 1 av hontyp, varvid haljet 3 har appna dndar. I haljet 3 är en styrenhet 6 anordnad. Vid den dnde av styrenheten 6 som är vdnd framAt, dvs. rarelseriktningen framdt has den elektriska gaffeltrucken T, är anordnad en konkav styryta 8. Denna rarelseriktning framAt är betecknad med pilen F i Fig. 1. Den konkava styrytan 8 definierar en frdmre dnde av styrenheten 6. I centrum av styrytan 8 är en ursparing 9 anordnad, varvid ursparingen 9 har en ldngd/ett djup som är anpassat till ldngden av nospartiet NP has handelen ME. Ett forskjutbart element 10 är anordnat i ursparingen 9, varvid det farskjutbara elementet har ett konkavt parti 11 som är %rant mot ursparingens 9 oppning. Faretrddesvis är det konkava partiet 11 halvsfdriskt far att Astadkomma en fullgod samverkan med nospartiet NP som faretrddesvis likasd är halvsfdriskt. Bakom det farskjutbara elementet 10 är anordnad en andra spiralfjader 12 som pressar det farskjutbara elementet 10 mot den appna dnden av ursparingen 9. I centrum av det konkava partiet 11 har det farskjutbara elementet 10 en appning 11A. Det farskjutbara elementet 10 rar sig i ursparingens 9 axiella riktning. Nar dockningsanordningen 1 av hontyp inte anvands tacker det forskjutbara elementet 10 den oppna anden av ursparingen 9. The female type docking device 1 according to the present invention comprises an outer housing 3 comprising two generally horizontal, flat disc elements 5 which are coated at a certain distance from each other, the distance being fed perpendicular to the plane of the disc-shaped elements 5. An alternative expression is that the disc elements 5 are coated at a certain vertical distance from each other. Two generally vertical elements 7 (only one is shown in Fig. 4) extend between the horizontal elements 5, the four elements 5 and 7 forming the cover 3 having the female-type docking device 1, the cover 3 having the openings. A control unit 6 is arranged in the housing 3.

However, since the contact point dr belgen next to the center of the control unit 6 and also the center of the recess 9, the control unit 6 will perform a pivoting movement as shown in Figs. 5A and 5B.

Svdngningsrorelsen beror pa att nospartiet NP pafar en kraft pa styrenheten 6 i kontaktpunkten mellan nospartiet NP och den konkava ytan 8. Detta initierar ett moment runt svdngningsaxeln A och en vridning av styrenheten 6 verkstalls. Pa grund av svdngningen av styrenheten 6, den konkava ytan 8 10 och flexibiliteten hos den forsta spiralfjddern HS kommer nospartiet NP hos handelen ME att antra ursparingen 9, se Fig. The pivoting movement is due to the nose portion NP applying a force to the control unit 6 at the point of contact between the nose portion NP and the concave surface 8. This initiates a moment around the pivot axis A and a rotation of the control unit 6 is effected. Due to the pivoting of the control unit 6, the concave surface 8 and the flexibility of the first coil spring HS, the nose portion NP of the trade ME will enter the recess 9, see Figs.

Den fOrsta ventilenheten 26 samverkar med en elektromagnet 27 som är anordnad i det ladformiga holjet HB. Den farsta ventilenheten 26 har dven ett undre lock 47. When it comes to the supply of pressurized, distilled water to the batteries of the electric forklift T, reference is made to Fig. 7 where the components arranged therein inside the charge-shaped housing HB are shown, the charge-shaped housing HB being depleted for clarity. A hose 25 is supplied with pressurized, distilled water extending inside the ladle-shaped casing HB and in the longitudinal direction of the ladle-shaped casing HB. In the embodiment shown, a first portion of the hose 25 is connected to an inlet 48 having a first valve unit 26 while a second portion of the hose 25 is connected to an outlet 49 having an upper lid 46 having the first valve unit 26. The inlet portion of the hose 25 is connected to a water-cold WS outside the charge-shaped housing HB, the water-cooled WS supplying pressurized, distilled water of a certain pressure to the hose 25. The first valve unit 26 cooperates with an electromagnet 27 arranged in the charging-shaped housing HB. The first valve unit 26 also has a lower cover 47.

Den farsta ventilenheten 26 innefattar ett baselement 50 som enligt den visade utfaringsformen har en generellt rektanguldr form. Baselementet 50 är fOrsett med en utskjutande kant 51 som likasa har en rektanguldr, sluten form. I utrymmet innanfor kanten 51 mynnar en dnde av en vattengenomforing WP (ej visad i Fig. 7) och en 0-ring 52 är monterad runt en appning 53 has vattengenomforingen WP. The first valve unit 26 comprises a base element 50 which, according to the embodiment shown, has a generally rectangular gold shape. The base element 50 is provided with a projecting edge 51 which likewise has a rectangular, closed shape. In the space inside the edge 51 an end of a water passage WP (not shown in Fig. 7) opens and an O-ring 52 is mounted around an opening 53 having the water passage WP.

Vattengenomforingen WP strdcker sig mellan utrymmet innanfar kanten 51 och inloppet 48 has den forsta ventilenheten 26. Den farsta ventilenheten 26 innefattar dessutom en platta 54 som har en yttre kontur som passar mot den inre konturen has kanten 51. The water passage WP extends between the space inside the edge 51 and the inlet 48 has the first valve unit 26. The first valve unit 26 further comprises a plate 54 which has an outer contour which fits against the inner contour has the edge 51.

Inuti det ladformiga holjet HB är tva styrstanger GB anordnade, varvid styrstangerna GB är del av en bdrkonstruktion inuti det ladformiga hOljet HB. Sasom framgar av Fig. 7 är en del av de elektriska kablarna EC lindade runt en del av styrstdngerna GB, varvid spolarna av de elektriska kablarna EC och de tillhorande partierna av styrstdngerna GB utgor en del av en elektromagnet 27. En forutsattning for detta arrangemang är att styrstangerna GB är utformade av ett magnetiserbart material, normalt jam. Inside the loading-shaped housing HB, two guide rods GB are arranged, the guide rods GB being part of a frame structure inside the loading-shaped housing HB. As shown in Fig. 7, a part of the electric cables EC is wound around a part of the control rods GB, the coils of the electric cables EC and the associated portions of the control rods GB forming part of an electromagnet 27. A prerequisite for this arrangement is that the guide rods GB are formed of a magnetizable material, normally jam.

Elektromagneten 27 innefattar dessutom block 60 av magnetiserbart material, normalt jam, varvid styrstdngerna GB strdcker sig genom blacken 60. Blacken 60 utgar tva poler av elektromagneten 27. Ett tvarstallt element 61 som overbroar styrstangerna GB dr ocksa en del av elektromagneten 27, dvs. det tvdrstallda elementet 61 dr gjort av magnetiserbart 9 material. Nar likstrom flyter i de elektriska kablarna EC kommer spolpartierna, det tvarstallda elementet 61 och jarnblocken 60 att fungera som en elektromagnet 27, dvs. ett magnetfalt etableras mellan polerna 60. The electromagnet 27 further comprises blocks 60 of magnetizable material, normally jam, the guide rods GB extending through the black 60. The black 60 emits two poles of the electromagnet 27. A transverse element 61 which bridges the guide rods GB also houses a part of the electromagnet 27, i.e. the two-dimensional element 61 is made of magnetizable 9 material. When direct current flows in the electrical cables EC, the coil portions, the transverse element 61 and the iron blocks 60 will function as an electromagnet 27, i.e. a magnetic field is established between the poles 60.

I Fig. 8A och 8B ar funktionen has elektromagneten 27 schematiskt visad. Av tydlighetsskal har delar av komponenterna tagits bort. De byre och undre locken 46, 47 är vattentatt hopsatta medelst en tatning 56. In Figs. 8A and 8B, the function of the electromagnet 27 is schematically shown.

I Fig. 8A är elektromagneten 27 aktiv och plattan 54 pressas mot utrymmet innanfor kanten 51 has baselementet 50. Detta innebar att plattan 54 pressar samman 0-ringen 52 och oppningen 53 tillsluts, dvs. det trycksatta vattnet kan endast na tram till anden has vattengenomfOringen WP, dvs. till kontaktpartiet mellan 0-ringen 52 och plattan 54. Detta illustreras medelst pilarna i Fig. 8A. Inget trycksatt vatten kan saledes nâ tram till nospartiet NP has handelen ME. In Fig. 8A, the electromagnet 27 is active and the plate 54 is pressed against the space inside the edge 51 having the base element 50. This meant that the plate 54 compresses the O-ring 52 and the opening 53 is closed, i.e. the pressurized water can only reach the tram to the other has the water passage WP, ie. to the contact portion between the O-ring 52 and the plate 54. This is illustrated by the arrows in Fig. 8A. No pressurized water can thus reach the tram to the muzzle NP has the trade ME.

I Fig. 8B är elektromagneten 27 inaktiv, dvs. ingen likstrOm flyter i de elektriska kablarna EC. Detta betyder att plattan 54 inte pressas mot 0-ringen 52. En utl5sningsfjader 55 inuti den farsta ventilenheten 26 lyfter upp plattan 54 ett visst stycke och trycksatt vatten strOmmar i vattengenomforingen WP, kan passera farbi 0-ringen och oppningen 53 och strommar genom utloppet 49 has den farsta ventilenheten 26. Detta illustreras medelst pilarna i Fig. 8B. In Fig. 8B, the electromagnet 27 is inactive, i.e. no direct current flows in the electrical cables EC. This means that the plate 54 is not pressed against the O-ring 52. A release spring 55 inside the first valve unit 26 lifts the plate 54 a certain distance and pressurized water flows in the water passage WP, can pass the pass ring and the opening 53 and flows through the outlet 49. has the first valve unit 26. This is illustrated by the arrows in Fig. 8B.

I detta sammanhang skall namnas att under vissa betingelser kan utlosningsfjadern 55 utelamnas, dvs. expansionen av 0- ringen 52 kommer att lyfta upp plattan 54. In this context, it should be mentioned that under certain conditions the release spring 55 can be omitted, ie. the expansion of the 0-ring 52 will lift the plate 54.

Slangen 25 stracker sig fran utloppet 49 has den forsta ventilenheten 26 och vidare inuti den fOrsta spiralfjadern HS och hela vagen till en andra ventilenhet 28 som dr belagen i nospartiet NP has handelen ME, se Fig. 4 som visar en sprangvy av den andra ventilenheten 28.

According to the embodiment shown, the diameter has the tail 37 slightly smaller than the diameter has the pin 36.

Sasom visas i Fig. 4 dr ett aktiverande stiftelement 40 monterat i batten pa ursparingen 9. Det aktiverande stiftelementet 40 ar monterat i en bakre vagg 41 has styrenheten 6. Det aktiverande stiftet 40 har en central genomgaende passage 42 som stracker sig i axiell riktning av stiftelementet 40. Den fria anden av stiftelementet 40 som ar beldgen i ursparingen 9 ar atminstone delvis konisk. I omradet far den koniska anden är en tvargaende borrning 43 anordnad, varvid borrningen 43 stracker sig fran den centrala passagen 42 till stiftelementets 40 omkrets. Den fria dnden 44 av stiftelementet 40 som är belagen utanfor ursparingen 9 ar avsedd att uppta en slang (ej visad) som transporterar destillerat vatten till batterierna (ej visade) som dr monterade pa den elektriska gaffeltrucken T. As shown in Fig. 4, there is an activating pin member 40 mounted in the batten of the recess 9. The activating pin member 40 is mounted in a rear cradle 41 having the guide unit 6. The activating pin 40 has a central through passage 42 extending in the axial direction of the pin member 40. The free end of the pin member 40 which is the bellows in the recess 9 is at least partially conical. A transverse bore 43 is provided in the area of the conical spirit, the bore 43 extending from the central passage 42 to the circumference of the pin element 40. The free end 44 of the pin element 40 which is located outside the recess 9 is intended to receive a hose (not shown) which transports distilled water to the batteries (not shown) which are mounted thereon on the electric forklift T.

Den andra ventilenheten 28 ar monterad i nospartiet NP pa handelen ME i ett hopsatt tillstand. Den andra ventilenheten 28 är monterad i ett utrymme som befinner sig narheten av nospartiets NP fria ande. Vid nospartiets fria ande dr ett genomgaende axiellt hal AH anordnat. Det hopsatta tillstandet av den andra ventilenheten 28 visas i Fig. 9A-9C som visar dockningen av handelen ME i dockningsanordningen 1 av hontyp. Sasom visas i Fig. 9A och 9B dr packboxen 33 monterad pa tappen 36, dvs. tappen 36 är upptagen i halet 37. The second valve unit 28 is mounted in the nose portion NP on the trade ME in an assembled condition. The second valve assembly 28 is mounted in a space located near the free spirit of the nose portion NP. At the free spirit of the muzzle, a continuous axial hal AH is arranged. The assembled state of the second valve unit 28 is shown in Figs. 9A-9C which show the docking of the trade ME in the female type docking device 1. As shown in Figs. 9A and 9B, the stuffing box 33 is mounted on the pin 36, i.e. the pin 36 is received in the tail 37.

Eftersom diametern has tappen 36 dr nagot storre an diametern has halet 37 dr packboxen 33 monterad pa tappen 36 medelst presspassning. Since the diameter 36 of the pin 36 is slightly larger than the diameter, the tail 37 of the stuffing box 33 is mounted on the pin 36 by means of a press fit.

I Fig. 9A har nospartiet NP has handelen ME etablerat kontakt med det farskjutbara elementet 10 has II dockningsanordningen 1 av hontyp. Ytterligare farskjutning framat av nospartiet NP kommer att forskjuta det farskjutbara elementet 10 djupare in i ursparingen 9, se Fig. 9B. I positionerna som visas i Fig. 9A och 9B är packboxen 33 monterad pa tappen 36 och trycksatt destillerat vatten i sparen 35 kommer inte att kunna passera f5rbi packboxen 33 eftersom en tdtning är etablerad bade mellan omkretsen hos packboxen 33 och insidan av det cylindriska raret 29 liksom mellan tappen 36 och centrumhalet 37 i packboxen 33. In Fig. 9A, the nose portion NP has the trade ME has established contact with the displaceable element 10 has II of the female type docking device 1. Further forward displacement of the nose portion NP will displace the displaceable element 10 deeper into the recess 9, see Fig. 9B. In the positions shown in Figs. 9A and 9B, the stuffing box 33 is mounted on the pin 36 and pressurized distilled water in the groove 35 will not be able to pass past the stuffing box 33 because a seal is established both between the circumference of the stuffing box 33 and the inside of the cylindrical tube 29. as well as between the pin 36 and the center tail 37 in the stuffing box 33.

Ytterligare farskjutning framat av nospartiet NP kommer att farskjuta det forskjutbara elementet 10 till ett ldge ddr det f5rskjutbara elementet 10 kommer till anliggning mot den bakre vdggen 41 has styrenheten 6 has dockningsanordningen 1 av hontyp. Detta illustreras i Fig. 9C. Nar det farskjutbara elementet 1: kommer till anliggning mot den bakre vaggen 41 är den andra spiralfjddern 12 helt hoptryckt. Under den slutliga fasen av inforandet av nospartiet NP in i ursparingen 9 kommer den fria anden av det aktiverande stiftelementet 40 som dr belaget i ursparingen 9 att stracka sig genom Mien 11A och AU och etablera kontakt med den fria dnden av tappen 36, varvid den koniska utformningen av dessa fria andar kommer att samverka. Sasom framgar av Fig. 9C kommer anden av det aktiverande stiftet 40 att pressa sliden 32 bakat och den tredje spiralfjddern 31 kommer att komprimeras. Under denna forskjutning av sliden 32 kommer packboxen 33 att antra den del av det aktiverande stiftet 40 som är beldget ndrmast den fria anden av det aktiverande stiftet 40 som ar belagen ursparingen 9. Av den anledningen är det lampligt att diametern has den fria dnden av det aktiverande stiftet 40 som upptar packboxen 33 har samma diameter som tappen 36. Sasom framgar av Fig. 9C kan trycksatt, destillerat vatten i sparen 35 nu passera fOrbi tappen 36 och via den tvdrgaende borrningen 43 till den centrala passagen 42 has det aktiverande stiftelementet 40. Det trycksatta, destillerade vattnet fortsdtter darefter till batterierna (ej visade) som ar anordnade pa den elektriska gaffeltrucken T via slangen (ej visad) som är monterad pa den fria anden 44 av det aktiverande stiftet 40 som är beldget utanfOr ursparingen 9. 12 Vid det ± Fig. 9C visade laget av nospartiet NP anligger de forsta och andra elektriska kontaktorganen CM och 13 mot varandra. Further forward displacement of the nose portion NP will advance the displaceable element 10 to a length where the displaceable element 10 comes into abutment against the rear wall 41 having the control unit 6 having the female type docking device 1. This is illustrated in Fig. 9C. When the displaceable element 1: comes into abutment against the rear cradle 41, the second coil spring 12 is completely compressed. During the final phase of the insertion of the nose portion NP into the recess 9, the free spirit of the activating pin element 40 which is coated in the recess 9 will extend through the Mien 11A and AU and establish contact with the free end of the pin 36, the conical the design of these free spirits will interact. As shown in Fig. 9C, the spirit of the activating pin 40 will press the slide 32 backwards and the third coil spring 31 will be compressed. During this displacement of the slide 32, the stuffing box 33 will enter the part of the activating pin 40 which is bellows closer to the free spirit of the activating pin 40 which is coated with the recess 9. For this reason it is appropriate that the diameter has the free end of the the actuating pin 40 receiving the stuffing box 33 has the same diameter as the pin 36. As can be seen from Fig. 9C, pressurized, distilled water in the groove 35 can now pass the pin 36 and via the transverse bore 43 to the central passage 42 the activating pin element 40. The pressurized distilled water then proceeds to the batteries (not shown) mounted on the electric forklift T via the hose (not shown) mounted on the free end 44 of the actuating pin 40 which is bellows outside the recess 9. 12 At the Fig. 9C shows the layer of the nose portion NP abutting the first and second electrical contact means CM and 13 against each other.

Vid det ± Fig. 9C illustrerade laget kan bade laddning av batterierna och tillforsel av destillerat vatten till batterierna aga rum. Laddningen, dvs. leverans av likstram, har beskrivits ovan. Tillfarsel av destillerat vatten startar nar batterierna (ej visade) som är anordnade pa den elektriska gaffeltrucken T ar helt laddade. Darvid kommer fladet av likstram i de elektriska kablarna EC att upphara och elektromagneten 27 kommer att inta ett inaktivt lage. Sasom har beskrivits ovan kommer trycksatt vatten darvid att passera farbi den forsta ventilenheten 26 och det trycksatta, destillerade vattnet kommer att na fram till batterierna som ar anordnade pa den elektriska gaffeltrucken T. In the case illustrated in Fig. 9C, both charging of the batteries and supply of distilled water to the batteries can take place. The charge, i.e. delivery of trunks, has been described above. The supply of distilled water starts when the batteries (not shown) arranged on the electric forklift truck are fully charged. Thereby, the surface of the direct current in the electrical cables EC will cease and the electromagnet 27 will assume an inactive state. As described above, pressurized water will then pass the first valve assembly 26 and the pressurized distilled water will reach the batteries provided on the electric forklift T.

I detta sammanhang skall papekas att det ovan beskrivna konceptet med att ha en elektromagnet som styr vattentillforseln under en laddningscykel av batterierna skall ses som en oberoende uppfinning. Detta betyder att den elektriska laddningen av batterierna inte behaver utfaras vid dockning av en handel i en dockningsanordning av hontyp. Laddningen kan utfaras pa alternativa satt. Uppfinningens koncept ar att en elektromagnet aktiveras genom de elektriska kablar EC som tillfor likstrom till batterierna far att ladda dem. Nar laddningen är avslutad kommer tillforseln av likstrom att upphora och elektromagneten 27 är inte langre aktiv. Detta betyder att det farsta ventilelementet 26 appnas och vattentillforseln till batterierna paborjas. In this context, it should be noted that the above-described concept of having an electromagnet that controls the water supply during a charge cycle of the batteries should be seen as an independent invention. This means that the electric charge of the batteries does not have to be carried out when docking a trade in a female-type docking device. The charge can be performed in alternative ways. The concept of the invention is that an electromagnet is activated by the electrical cables EC which supply direct current to the batteries to charge them. When the charging is completed, the supply of direct current will cease and the electromagnet 27 is no longer active. This means that the first valve element 26 is opened and the water supply to the batteries is drilled.

I Fig. 10 visas en alternativ utforingsform av dockningsanordningen 101 av hontyp. I Fig. 10 finns aven en handel ME, varvid denna handel ME i princip är identisk med den ovan beskrivna handelen ME. Av den anledningen har de Asatts samma hanvisningsbeteckning. Fig. 10 shows an alternative embodiment of the female-type docking device 101. In Fig. 10 there is also a trade ME, this trade ME being in principle identical to the trade ME described above. For that reason, they have Asatts the same male designation.

Den huvudsakliga skillnaden mellan dockningsanordningen 35 101 av hontyp och dockningsanordningen 1 av hontyp är att dockningsanordningen 101 av hontyp saknar ett stationart holje. The main difference between the female-type docking device 101 and the female-type docking device 1 is that the female-type docking device 101 lacks a stationary housing.

Dockningsanordningen 101 av hontyp innefattar en styrenhet 106 som dr svangbar runt en skruv 114 som definierar 13 en svangningsaxel som styrenheten 106 kan svanga/vridas runt. Skruven 114 ar upptagen i ett hal i en botten has styrenheten 106. Skruven 114 dr fOrankrad i ett stationart baselement 104 som ar stelt infast till den elektriska gaffeltrucken (ej visad). Pa motsvarande satt som vid dockningsanordningen 1 av hontyp ar styrenheten 106 has dockningsanordningen 101 av hontyp forsedd med en konkav styryta 108 och en ursparing 109 i centrum av den konkava styrytan 108. Ett forskjutbart element 110 ar anordnat i ursparingen 109. Mellan det stationara baselementet 104 och en del av dockningsanordningen 101 av hontyp dr returfjadrar 115 (endast synliga i Fig. 10) anordnade. The female-type docking device 101 includes a control unit 106 which pivots about a screw 114 which defines a pivot axis about which the control unit 106 can pivot / rotate. The screw 114 is received in a hall in a bottom has the control unit 106. The screw 114 is anchored in a stationary base element 104 which is rigidly attached to the electric forklift (not shown). In the same way as with the female type docking device 1, the control unit 106 has a female type docking device 101 provided with a concave guide surface 108 and a recess 109 in the center of the concave guide surface 108. A slidable element 110 is arranged in the recess 109. Between the stationary base member 104 and a part of the docking device 101 of female type dr return springs 115 (only visible in Fig. 10) are arranged.

Om det finns en felaktig inriktning mellan nospartiet NP has handelen ME och ursparingen 109 kommer nospartiet NP att traffa styrytan 108 vid sidan av ursparingen 109. Detta initierar ett vridande moment pa styrenheten 106, dvs. styrenheten 106 kommer att svanga/vrida sig runt axeln som definieras av skruven 114. If there is a misalignment between the nose portion NP has the trade ME and the recess 109, the nose portion NP will hit the guide surface 108 next to the recess 109. This initiates a rotating moment on the control unit 106, i.e. the control unit 106 will pivot / rotate about the axis defined by the screw 114.

I Fig. 11 visas ett snedstallt lage av styrenheten 106. Fig. 11 shows an inclined layer of the control unit 106.

Av Fig. 11 framgar att vridningen av styrenheten 106 bringar en av returfjadrarna 115 att komprimeras medan den andra returfjadern 115 farlangs. Pa motsvarande satt som beskrivits ovan kommer den rundade formen has nospartiet NP, den konkava styrytan 108 och snedstallningen av styrenheten 106 att sakerstalla att fullgod dockning uppnas aven cm det finns en pfelaktig inriktning mellan handelen ME och dockningsanordningen 101 av hontyp. Fig. 11 shows that the rotation of the control unit 106 causes one of the return springs 115 to be compressed while the other return spring 115 is flanged. In the same manner as described above, the rounded shape has the nose portion NP, the concave guide surface 108 and the inclination of the control unit 106 will ensure that adequate docking is achieved even if there is an erroneous alignment between the trade ME and the female type docking device 101.

Nar handelen ME frikopplas fain dockningsanordningen 101 av hontyp kommer returfjadrarna 115 att farskjuta styrenheten 106 till sitt neutrallage. When the trade ME is disengaged from the female-type docking device 101, the return springs 115 will push the control unit 106 to its neutral position.

Tankbara modifikationer av uppfinningen Vid de ovan beskrivna utforingsformerna dr styrytan 8; 108 konkav. mom ramen for foreliggande uppfinning kan man 35 aven -Lanka sig att styrytan har formen av en stympad kan. 14 Conceivable modifications of the invention In the embodiments described above, the guide surface 8; 108 concave. In the context of the present invention, it can also be seen that the guide surface has the shape of a truncated can. 14
