Abstract

A trolley (B), which is adapted to be connected to a wheel-mounted loading trolley (A), has idle wheels (2, 2a) on which it can be wheeled by hand, either alone or together with the loading trolley (A). The trolley (B) further has a motor-driven wheel (4). The wheel (4) and the associated motor (3) are fixed to a tube (9) which is vertically displaceable and rotatably mounted in the chassis (13) of the trolley (B). By an operating handle (10), the tube (9) can be vertically displaced in the chassis (13). The operating handle (10) is articulated to the tube (9) and the chassis (13) by means of a dead-centre elbow mechanism (11). In the one stable position of the elbow mechanism (11), the motor-driven wheel (4) has floor contact in order to drive the trollley (B) and the loading trolley (A), if connected thereto. In the other stable position of the elbow mechanism (11), only the idle wheels (2, 2a) of the trolley (B) have floor contact when the trolley (B) is connected to the loading trolley (A).

Description

501 10 15 20 25 30 35 258 2 mekaniskt hopkopplingsbar med lastvagnen A för motordriv- ning av denna. Hjulet 4 är tillsammans med sin motor 3 förflyttbart vertikalt upp och ned i motorvagnen B, så att hjulet 4 kan bringas till ingrepp med golvet C, varigenom motorvagnen B och den därtill kopplade lastvagnen A kan motordrivas för rörelse på golvet C (fig 2A resp lB), var- vid motorvagnshjulen 2, 2a saknar golvkontakt. I uppläget B och den eventuellt tillkopp- lade lastvagnen A manuellt skjutbara pá golvet C med hand- kraft, med hjälp av hjulen 1, 2a, 2 (fig 1A resp 2B) eller, i det hopkopplade tillståndet, företrädesvis blott med hjälp av hjulen 1, för minskning av tröskelpasserings- av hjulet 4 är motorvagnen problem, varvid vagnen B hänger fritt pà lastvagnen A. Så- som framgàr i figurerna är hjulet 4 placerat baktill på motorvagnen B, bakom hjulen 2, 2a, sà med hjulet 4 i det nedre läget, drivläget, golvkontakt kan fås också med länkhjulen 2a, för drivning av motorvagnen B separat. 501 10 15 20 25 30 35 258 2 mechanically interconnectable with truck A for motor drive thereof. The wheel 4 together with its motor 3 can be moved vertically up and down in the motor car B, so that the wheel 4 can be brought into engagement with the floor C, whereby the motor car B and the truck A connected thereto can be motor driven for movement on the floor C (Figs. 2A and 1B, respectively). ), whereby the motor vehicle wheels 2, 2a have no floor contact. In position B and the possibly coupled truck A can be manually slid on the floor C by hand, by means of the wheels 1, 2a, 2 (fig. 1A and 2B respectively) or, in the coupled condition, preferably only by means of the wheels 1 , to reduce the threshold passage of the wheel 4, the motor vehicle is a problem, the carriage B hanging freely on the truck A. As shown in the figures, the wheel 4 is placed at the rear of the motor vehicle B, behind the wheels 2, 2a, so with the wheel 4 in the lower the position, drive position, floor contact can also be obtained with the castors 2a, for driving the motor vehicle B separately.

För nämnda mekaniska hopkoppling av vagnarna A och B finns hakar 5 pá motorvagnen B och fickor eller stänger 7, 8 pà vagnen A. Haken 5 är ledad och företrädesvis fjäder- belastad, så att först haken 6 bringas till ingrepp med sin ficka eller stång 7 (efter tippning av motorvagnen B medurs i fig 1 och 2), varpå haken 5 bringas till ingrepp med sin ficka eller stång 8. Denna hopkopplingsprincip beskrivs också i EP-Bl-0 281 536, liksom andra här likaså användbara hopkopplingsarrangemang.For said mechanical coupling of the carriages A and B, there are hooks 5 on the motor carriage B and pockets or rods 7, 8 on the carriage A. The hook 5 is hinged and preferably spring-loaded, so that first the hook 6 is brought into engagement with its pocket or rod 7. (after tipping the motor car B clockwise in Figs. 1 and 2), whereupon the hook 5 is brought into engagement with its pocket or rod 8. This coupling principle is also described in EP-B1-0 0 281 536, as well as other coupling arrangements which are also useful here.

Nämnda vertikala förflyttning av hjulet 4 och dess motor 3 àvägabringas medelst ett med hjulet 4 och dess motor 3 fast förbundet rör 9, ett manöverhandtag 10 och en detaljerna 9 och 10 förbindande dödpunktsknäledsmekanism ll (se fig 3). Manöverhandtaget 10 är ledbart förbundet dels med röret 9 vid 12 dels med ett med motorvagnens chassi 13 (som uppbär hjulen 2, 2a) fast förbundet rör 14 medelst en länk 15, i vilket rör 14 röret 9 är förflytt- bart upp och ned och även kan vridas kring sin längdaxel.Said vertical movement of the wheel 4 and its motor 3 is effected by means of a tube 9 fixedly connected to the wheel 4 and its motor 3, an operating handle 10 and a dead center knee joint mechanism 11 connecting the parts 9 and 10 (see Fig. 3). The operating handle 10 is hingedly connected partly to the tube 9 at 12 and partly to a tube 14 fixedly connected to the chassis 13 (which supports the wheels 2, 2a) by means of a link 15, in which tube 14 the tube 9 is movable up and down and also can be rotated about its longitudinal axis.

Knäledsmekanismen 11 är sådan att för motordrivning pà plant golv C av vagnen A (alla hjulen 1, 2, 2A - eller 10 15 20 25 30 35 501 258 3 blott hjulen 1 - medger golvkontakt) skall knäledsmekanis- men 11 passera från ett läge där handtaget 10 är verti- kalt, streckad linje 10' (centrumaxel), och hjulen 2, 2a är upplyfta från golvkontakt, till ett läge svängt 90°, streckad linje 10", där hjulen 2, 2a släppt golvkontakten (röret 9 vertikalt), varvid ett dödpunktsläge skall ha passerats, såsom antydes med streckad länk 15. Detta för att vilja av operatören skall effektueras för àstadkomman- de av de två stabila ändlägena för drivhjulet 4.The knee joint mechanism 11 is such that for motor drive on flat floor C of the carriage A (all wheels 1, 2, 2A - or only the wheels 1 - allow floor contact) the knee joint mechanism 11 must pass from a position where the handle 10 is vertical, dashed line 10 '(center axis), and the wheels 2, 2a are raised from floor contact, to a position turned 90 °, dashed line 10 ", where the wheels 2, 2a have released the floor contact (pipe 9 vertically), whereby a dead center position must have been passed, as indicated by a dashed link 15. This is so that the will of the operator is effected to achieve the two stable end positions of the drive wheel 4.

Lämplig inställning av rörets 9 slaglängd kan åstad- kommas genom att ledpunkten 16 för länken 15 på röret 14 anordnas på en på röret 14 höjdförskjutbar och i inställt höjdläge fixerbar stoppbussning 17, som vidare är vridbar på röret 14 för att medge vridning av hjulet 4, sá att vagnen A kan styras åt olika håll.Appropriate adjustment of the stroke of the tube 9 can be achieved by arranging the hinge point 16 of the link 15 on the tube 14 on a stop bushing 17 which is displaceable on the tube 14 and fixable in the set height position, which is further rotatable on the tube 14 to allow rotation of the wheel 4. saw that the carriage A can be steered in different directions.

En elektrisk ledning 18 som löper genom röret 9 för- binder elektriska styrdon 19 på handtaget 10 med motorn 3 via styrelektronik 20 för motorn 3, som bl a kan vara in- rättad för hastighetsreglering och reversering av motorn 3. 21 betecknar ett laddningsbart batteri och 22 en bat- teriladdare, som laddas från ett vägguttag genom en el- ledning 23.An electrical line 18 running through the tube 9 connects electrical controls 19 on the handle 10 to the motor 3 via control electronics 20 for the motor 3, which may be arranged, among other things, for speed control and reversing of the motor 3. 21 denotes a rechargeable battery and 22 a battery charger, which is charged from a wall socket by a power cord 23.
