Den foreliggende opfindelse angår en styrearm til betjening af en manuel løftevogn, af den art, der omfatter en stang, hvis nedre ende er drejeligt forbundet med en bærer for løftevognens styrende forhjul, 5 et håndtag, som er stift fastgjort på stangen i området ved dennes øvre ende og har form af en ring, som har stangens længdeakse som symmetriakse, og et betjenings-greb, som er drejeligt monteret på stangen omkring en på stangens længdeakse vinkelret omdrejningsakse og 10 strækker sig inden i den af håndtaget dannede ring på en sådan måde, at det af en operatør, som holder håndtaget uden at give slip på dette, kan aktiveres manuelt.BACKGROUND OF THE INVENTION The present invention relates to a control lever for operating a manual lifting car, of the kind comprising a rod, the lower end of which is pivotally connected to a carrier of the lifting front wheel of the lifting vehicle, a handle rigidly secured to the rod in the region thereof. upper end and in the form of a ring having the longitudinal axis of the rod as a axis of symmetry, and an operating handle pivotally mounted to the rod about a rotational axis perpendicular to the longitudinal axis and extending within the ring formed by the handle in such a manner , that it can be manually activated by an operator holding the handle without letting go of it.
Styrearme af den ovenfor nævnte art er velkendte. 15 De anvendes til betjening af eksempelvis de af ansøger fremstillede og under benævnelsen TM 2000 markedsførte løftevogne eller til betjening af transportvogne af den art, som er beskrevet i ansøgers patent FR-2 718 093. På de kendte styrearme er styrearmens stang og håndta-20 get fastgjort til hinanden i to modstående punkter af den af håndtaget dannede ring, idet stangen deler ringens indre rum i to halvrum, som er fuldstændig adskilt fra hinanden. Betjeningsgrebet strækker sig lateralt ud fra en side af stangen i et af de to førnævn-25 te halvrum og kan dreje omkring en akse, som er vinkelret på planet af den af håndtaget dannede ring. Det øvre afsnit af ringen er omtrent vandret og vinkelret på styrearmens stang. Betjeningsgrebet, som tjener til at aktivere en fordeler af hydraulikfluid forbundet med 30 en enhed bestående af hydraulikpumpe og -donkraft for løftevognen, har sædvanligvis tre stillinger, nemlig en neutral stilling, i hvilken betjeningsgrebet strækker sig næsten parallelt med den øvre vandrette del af håndtaget, og to arbejdsstillinger placeret henholdsvis 2 2DK 97 00247 U3 på den ene side og på den anden side af den neutrale stilling.Guide arms of the kind mentioned above are well known. 15 They are used to operate, for example, the lift trucks which are manufactured and marketed by the applicant and referred to as TM 2000 or for the operation of transport trucks of the kind described in the applicant's patent FR-2 718 093. On the known guide arms, the rod and handle 20 The rod is attached to each other at two opposite points of the ring formed by the handle, the rod dividing the inner space of the ring into two half-spaces which are completely separated from each other. The actuating lever extends laterally from one side of the rod in one of the two aforementioned half-spaces and can rotate about an axis perpendicular to the plane of the handle formed by the handle. The upper portion of the ring is approximately horizontal and perpendicular to the rod of the control arm. The control handle, which serves to activate a hydraulic fluid distributor connected to a unit of hydraulic pump and jack for the lift truck, usually has three positions, namely a neutral position in which the control handle extends almost parallel to the upper horizontal portion of the handle. and two working positions located respectively 2 2DK 97 00247 U3 on one side and on the other side of the neutral position.
Ved brug holder løftevognens operatør normalt håndtaget med to hænder, idet de to hænder er placeret 5 på det øvre afsnit af håndtaget, henholdsvis på den ene side og på den anden side af styrearmens stang. Med den beskrevne placering, som er højere end betjenings-grebet, kan operatøren ikke aktivere betjeningsgrebet med mere end én hånd alene, det være sig den højre hånd 10 eller den venstre hånd, alt efter om betjeningsgrebet strækker sig i det ene eller det andet af de to ovenfor nævnte halvrum af den af håndtaget dannede ring. Dette udgør en begrænsning, som nogle gange kan være generende for betjeningen af løftevognen.In use, the operator of the truck normally holds the handle with two hands, the two hands being located 5 on the upper part of the handle, on one side and the other side of the handlebar rod, respectively. With the position described which is higher than the control handle, the operator cannot activate the control handle with more than one hand alone, be it the right hand 10 or the left hand, depending on whether the control handle extends in one or the other of the the two halves mentioned above of the ring formed by the handle. This constitutes a restriction which can sometimes be a nuisance to the operation of the truck.
15 Den foreliggende opfindelse har til formål at afhjælpe denne ulempe ved at tilvejebringe en betjeningsarm til en løftevogn eller lignende vogn, hvor betjeningsgrebet kan aktiveres med lige meget hvilken af operatørens to hænder eller eventuelt med begge 20 hænder samtidig.The present invention aims to alleviate this disadvantage by providing a control arm for a lift truck or similar trolley where the control handle can be actuated with either one of the operator's two hands or possibly with both hands simultaneously.
Med dette formål er styrearmen ifølge den fore-liggende opfindelse ejendommelig ved, at det ringformede håndtag er fastgjort på stangen i et eneste første punkt af ringen, således at der er et frit rum mellem 25 den øvre ende af stangen og et over for det første punkt beliggende andet punkt af ringen, og at betjeningsgrebet er monteret drejeligt ved den øvre ende af stangen og strækker sig langsgående i det nævnte frie rum fra den øvre ende af stangen mod det andet punkt af 30 ringen.For this purpose, the guide arm of the present invention is characterized in that the annular handle is secured to the rod at a single first point of the ring, so that there is a free space between the upper end of the rod and one opposite the first. point is located second point of the ring and the control handle is pivotally mounted at the upper end of the rod and extends longitudinally in said free space from the upper end of the rod towards the other point of the ring.
Betjeningsgrebets omdrejningsakse er fortrinsvis placeret i eller i det væsentlige i planet af den af håndtaget dannede ring, og betjeningsgrebet er kun placeret i dette plan, når det befinder sig i sin 35 neutrale hvilestilling.The axis of rotation of the control handle is preferably located in or substantially in the plane of the ring formed by the handle, and the control handle is placed in this plane only when it is in its neutral rest position.

Betjeningsgrebet har fortrinsvis form som et T, hvor den vandrette stang af Τ'et er parallel med det øvre vandrette afsnit af den af håndtaget dannede ring.Preferably, the operating handle is in the form of a T, where the horizontal bar of the Τ is parallel to the upper horizontal section of the ring formed by the handle.
Den foreliggende opfindelse vil i det følgende blive beskrevet nærmere ved hjælp af to eksempler på udførelsesformer for opfindelsen under henvisning til tegningen, på hvilken fig. 1 viser et perspektivbillede af en løftevogn forsynet med en styrearm ifølge en første udførelses-form for opfindelsen, fig. 2 et billede forfra af det øverste afsnit af styrearmen ifølge fig. 1, fig. 3 et billede snittet gennem linien III-III ifølge fig. 2, idet der i større målestoksforhold ses et betjeningsgreb indbygget i styrearmen, og fig. 4 et til figur 2 svarende billede, som skematisk viser en anden udførelsesform for opfindelsen.The present invention will now be described in more detail by way of two examples of embodiments of the invention with reference to the drawing, in which: 1 is a perspective view of a lift truck provided with a control arm according to a first embodiment of the invention; FIG. 2 is a front view of the upper section of the control arm according to FIG. 1, FIG. 3 is a sectional view taken along line III-III of FIG. 2, where, on a larger scale, a control handle is built into the control arm, and fig. 4 is a view similar to FIG. 2 schematically showing another embodiment of the invention.
Den i fig. 1 viste løftevogn 1 omfatter grundlæggende et stel 2, en konsol 3, som kan forskydes lodret i forhold til stellet 2, to gaffelarme 4, som strækker sig fra konsollen 3's underdel mod løftevognens bagende, og hvoraf de frie ender hviler på jorden ved hjælp af ruller 5, et par indbyrdes forbundne styrende forhjul 6 og en bærer 7 for de to hjul 6, hvor bæreren er monteret i stellet 2, således at den kan dreje omkring en lodret akse 8. Hjulbæreren 7 bærer oven over stellet 2 en hydraulisk gruppe 9 sammensat af en beholder 11 med hydraulikfluid, en stempelpumpe 12, en enkeltvirkende, hydraulisk donkraft 13, ved hjælp af hvilken konsollen 3 og gaffelarmen 4 kan hæves, og en fordeler af hydraulikfluid (ikke vist). Løftevognen 1 omfatter desuden en betjeningsarm 14, som udgøres af en stang 15 og et håndtag 16, som er stift fastgjort, eksempelvis ved svejsning, på stangen 15 i området ved dens øvre ende. Ved sin nedre ende er stangen 15 4 4DK 97 00247 U3 forsynet med et koblingsstykke 17 i form af en gaffel, ved hjælp af hvilken den er koblet over en vandret akse 18 til den hydrauliske gruppe 9's hus. Huset er stift forbundet med eller ud i ét med hjulbæreren 7. Løfte-5 vognens styrende hjul 6 kan således orienteres ved hjælp af styrearmen 14. Koblingsstykket 17 bærer en knast eller et lille hjul 19, som er excentrisk i forhold til aksen 18, og som ligger an mod den øverste ende af stempelstangen i stempelpumpen 12. Således· kan 10 pumpen 12 aktiveres, når man bevæger styrearmen 14 frem og tilbage omkring aksen 18.The FIG. 1, basically 1 comprises a frame 2, a bracket 3 which can be displaced vertically with respect to the frame 2, two fork arms 4 extending from the bottom of the bracket 3 towards the rear of the lift truck, the free ends of which rest on the ground by means of rollers 5, a pair of interconnected steering front wheels 6 and a carrier 7 for the two wheels 6, the carrier being mounted in the frame 2 so that it can rotate about a vertical axis 8. The wheel carrier 7 carries over the frame 2 a hydraulic group 9 composed of a container 11 with hydraulic fluid, a piston pump 12, a single-acting hydraulic jack 13 by means of which the bracket 3 and the fork arm 4 can be raised, and a distributor of hydraulic fluid (not shown). The lift truck 1 further comprises an operating arm 14, which is constituted by a rod 15 and a handle 16 which is rigidly secured, for example by welding, to the rod 15 in the region at its upper end. At its lower end, the rod 15 4 4DK 97 00247 U3 is provided with a coupling piece 17 in the form of a fork, by means of which it is coupled over a horizontal axis 18 to the housing of the hydraulic group 9. The housing is rigidly connected to or integral with the wheel carrier 7. Thus, the guiding wheel 6 of the lift car can be oriented by the guide arm 14. The coupling piece 17 carries a cam or small wheel 19 which is eccentric to the axis 18, and which abuts the upper end of the piston rod in the piston pump 12. Thus, the pump 12 can be actuated as the control arm 14 moves back and forth around the axis 18.
Håndtaget 16 har form som en ring. Inden i den af håndtaget 16 dannede ring befinder sig et betjeningsgreb 21, som på stangen 15 er monteret drejeligt 15 omkring en akse 22 (figurerne 2 og 3), som er vinkelret på stangens længdeakse. Betjeningsgrebet 21 er forbundet med den ovenfor nævnte fordeler af hydraulikfluid ved hjælp af et kraftoverførselselement 23 (fig. 3), såsom eksempelvis et kabel eller en kæde. Som vist 20 kan stangen 15 udgøres af et rørformet profil, som eksempelvis har et kvadratisk eller rektangulært tværsnit, og kraftoverførselselementet 23 strækker sig i længderetningen inden i stangen 15 ned til den hydrauliske gruppe 9, hvor det er forbundet med gli-25 deren i den ovenfor nævnte fordeler af hydraulikfluid. Betjeningsgrebet 21 kan indtage tre stillinger, som er benævnt henholdsvis med N, P og E i fig. 3, og hvortil svarer henholdsvis tre stillinger af glideren i fordeleren af hydraulikfluid. I stillingen N eller den 30 neutrale stilling etablerer fordeleren af hydraulikfluid et kredsløb i en lukket ring mellem beholderen 11 og pumpen 12, og enhver frem- og tilbagegående bevægelse af styrearmen 14 omkring aksen 18 har ingen virkning på donkraften 13. I stillingen P eller pum-35 pestillingen etablerer fordeleren af hydraulikfluid en 5 5DK 97 00247 U3 forbindelse mellem pumpen 12 og arbejdskammeret i donkraften 13, således at pumpen 12 ved frem- og tilbagegående bevægelse af styrearmen 14 omkring aksen 18 suger hydraulikfluid fra beholderen 11 og derefter presser det ind i arbejdskammeret i donkraften 13 for at hæve konsollen 3 og gaffelarmene 4. I stillingen E eller udstrømningsstillingen etablerer fordeleren af hydraulikfluid en forbindelse mellem arbejdskammeret i donkraften 13 og beholderen 11, således at konsollen 3 og gaffelarmene 4 sænker sig under indvirkning af deres egne vægte og på grund af den eventuelle last på gaffelarmene 4. Løftevognen 1, som indtil videre er blevet beskrevet, er af velkendt type, og det anses derfor ikke for formålstjenstlig at beskrive den mere detaljeret.The handle 16 is shaped like a ring. Inside the ring formed by the handle 16 is an operating handle 21 which is mounted on the rod 15 pivotally 15 about an axis 22 (Figures 2 and 3) perpendicular to the longitudinal axis of the rod. The control handle 21 is connected to the aforementioned hydraulic fluid distributor by means of a power transmission element 23 (Fig. 3), such as, for example, a cable or a chain. As shown 20, the rod 15 may be a tubular profile having, for example, a square or rectangular cross-section, and the PTO 23 extends longitudinally within the rod 15 down to the hydraulic group 9 where it is connected to the slider 25 in the the above-mentioned advantages of hydraulic fluid. The control handle 21 can occupy three positions, respectively designated N, P and E in FIG. 3 and corresponding to three positions of the slider respectively in the hydraulic fluid distributor. In the N or 30 neutral position, the hydraulic fluid distributor establishes a circuit in a closed ring between the container 11 and the pump 12, and any reciprocating movement of the control arm 14 about the axis 18 has no effect on the jack 13. In the P or pump position -35 pest position, the hydraulic fluid distributor establishes a connection between the pump 12 and the work chamber of the jack 13, so that, upon reciprocating movement of the control arm 14 about the axis 18, the hydraulic fluid sucks from the container 11 and then presses it into the the working chamber of the jack 13 to raise the bracket 3 and the fork arms 4. In the position E or the outflow position, the distributor of hydraulic fluid establishes a connection between the working chamber of the jack 13 and the container 11, so that the bracket 3 and the fork arms 4 are lowered under the influence of their own weights and on due to the possible load on the forks 4. The lift truck 1, as in so far described, are of a well-known type, and it is therefore not considered expedient to describe it in more detail.
Hvor stangen 15 på de kendte løftevogne strækker sig fuldstændig tværs igennem det indre rum af den af håndtaget 16 dannede ring, og er fastgjort til denne i to modstående punkter af ringen, så er håndtaget 16 på styrearmen 14 ifølge den foreliggende opfindelse fastgjort på stangen 15 i et eneste punkt 16a af ringen. Stangen 15 kan forløbe i det indre rum af ringen indtil et punkt placeret lidt fra midten af denne, således at der er et frit rum imellem den øvre ende 15a af stangen 15 og det til ringen hørende punkt 16b, som er beliggende over for punktet 16a. Som vist i fig. 3 befinder betjeningsgrebet 21's omdrejningsakse 22 sig i umiddelbar nærhed af den øvre ende 15a af stangen 15, og betjeningsgrebet 21 strækker sig langsgående fra aksen 22 mod punktet 16b. Kraftoverførselselementet 23 er forbundet med betjeningsgrebet 21 i et punkt 21a af dette, hvor punktet er placeret i omtrent samme højde som omdrejningsaksen 22, når betjeningsgrebet befinder sig i sin neutrale stilling N.Where the rod 15 of the known lift trucks extends completely across the inner space of the ring formed by the handle 16 and is secured thereto at two opposite points of the ring, then the handle 16 of the control arm 14 of the present invention is attached to the rod 15 in a single point 16a of the ring. The rod 15 may extend into the inner space of the ring until a point located slightly from the center thereof, so that there is a free space between the upper end 15a of the rod 15 and the point 16b of the ring, which is opposite the point 16a . As shown in FIG. 3, the axis of rotation 21 of the control lever 21 is in the immediate vicinity of the upper end 15a of the rod 15, and the control lever 21 extends longitudinally from the axis 22 toward the point 16b. The PTO 23 is connected to the control handle 21 at a point 21a thereof, the point being located at approximately the same height as the axis of rotation 22 when the control handle is in its neutral position N.
6 6DK 97 00247 U36 6GB 97 00247 U3
Betjeningsgrebet 21's omdrejningsakse 22 er fortrinsvis placeret i planet af den af håndtaget 16 dannede ring, som vist i fig. 2, eller den strækker sig parallelt med og i nærheden af dette plan, som vist i 5 fig. 3. Under disse forhold befinder betjeningsgrebet 21 sig kun i planet 24 af den af håndtaget 16 dannede ring, når det er i sin neutrale stilling N.The rotary axis 22 of the control lever 21 is preferably located in the plane of the ring formed by the handle 16, as shown in FIG. 2, or extending parallel to and near this plane, as shown in FIG. 3. Under these conditions, the operating handle 21 is in the plane 24 of the ring formed by the handle 16 only when in its neutral position N.
Betjeningsgrebet 21 kan holdes i den ene eller den anden af sine to stillinger N og P ved hjælp af en 10 holdeindretning 25 med en elastisk klinkemekanisme. Som vist i fig. 3 kan holdeindretningen 25 udgøres af en lille rulle 26, som kan rulle på en knast 27 båret af den ene ende af en bladfjeder 28, hvoraf den anden ende er stift fastgjort på stangen 15, uden på denne. Rullen 15 26 er drejeligt monteret i en trissegaffel 29, som er fastgjort på betjeningsgrebet 21 i området ved dets nedre ende, og den rager frem uden for stangen 15 igennem en udskæring 31 i randen af stangen 15's ende, på den ene side af denne. Knasten 27 har på den side, 20 som er i kontakt med rullen 26, to fordybninger 27a og 27b, som definerer henholdsvis stillingen N og P af betjeningsgrebet 21. Når grebet drejes manuelt omkring aksen 22, og rullen 26 går i indgreb med den ene eller den anden af de to fordybninger 27a og 27b, og grebet 25 21 derefter slippes, forbliver dette således i stillingen N eller P svarende til fordybningen 27a eller 27b. Når betjeningsgrebet 21 derimod bringes i stillingen E ved drejning omkring aksen· 22, frigør rullen 26 sig fra knasten 27, og når grebet 21 slippes, føres 30 det automatisk tilbage til sin stilling N ved hjælp af en tilbageføringsfjeder (ikke vist), som er forbundet med glideren i fordeleren af hydraulikfluid.The control handle 21 can be held in one or the other of its two positions N and P by means of a holding device 25 with an elastic clamping mechanism. As shown in FIG. 3, the retaining device 25 may be constituted by a small roller 26 which may roll on a cam 27 supported by one end of a leaf spring 28, the other end of which is rigidly secured to the rod 15, without it. The roller 15 26 is pivotally mounted in a pulley fork 29 which is secured to the operating handle 21 in the region at its lower end, and it protrudes outside the rod 15 through a cut-out 31 at the rim of the end of the rod 15, on one side thereof. The cam 27 has, on the side 20 in contact with the roller 26, two recesses 27a and 27b, respectively defining the positions N and P of the operating handle 21. When the handle is rotated manually around the axis 22 and the roller 26 engages one of the or the other of the two recesses 27a and 27b and the grip 25 21 is then released, thus remaining in position N or P corresponding to the recess 27a or 27b. On the other hand, when the control handle 21 is brought into position E by turning about the axis · 22, the roller 26 is released from the cam 27 and when the handle 21 is released, 30 is automatically returned to its position N by a return spring (not shown) which is connected to the slider in the hydraulic fluid distributor.
Betjeningsgrebet 21 har i området ved sin frie og modsat sin omdrejningsakse 22 beliggende ende fortrins-35 vis en sådan bredde, at en operatør, som holder håndta- 7 7DK 97 00247 U3 get 16 med to haender, kan aktivere betjeningsgrebet 22 ved hjælp af i det mindste én finger, eksempelvis tommelfingeren, på lige meget hvilken af sine to hænder eller på begge hænder på én gang. Med henblik herpå kan betjeningsgrebet 21, som vist i figurerne 1 og 2, eksempelvis have form som et T, hvor den vandrette stang af T'et er parallel med de til håndtaget 16 hørende to afsnit 16c, 16d, som er placeret henholdsvis på den ene og på den anden side af punktet 16b, og som ved brug normalt holdes af operatøren. Disse to afsnit 16c, 16d strækker sig i det væsentlige vinkelret på stangen 15's længdeakse.The operating handle 21 preferably has a width in the region at its free and opposite end of its axis of rotation 22 such that an operator holding the handle 16 with two hands can activate the operating handle 22 by means of at least one finger, such as the thumb, on either of its two hands or on both hands at once. For this purpose, the control handle 21, as shown in Figures 1 and 2, may, for example, take the form of a T, where the horizontal rod of the T is parallel to the two portions 16c, 16d of the handle 16 located respectively on the one and the other side of the point 16b, which is normally held by the operator during use. These two sections 16c, 16d extend substantially perpendicular to the longitudinal axis of the rod 15.
En skjuler 32 (ikke vist i fig. 3, men synlig i figurerne 1 og 2) er fastgjort på den øvre ende af stangen 15, således at den skjuler den øvre ende af denne, holdeindretningen 25 og den nedre ende af betjeningsgrebet 21. Skjuleren 32 kan udgøres af et lille hus, eksempelvis med form som en bikonveks linse, som vist i figurerne 1 og 2.A concealer 32 (not shown in Fig. 3, but visible in Figures 1 and 2) is secured to the upper end of the bar 15 so that it conceals the upper end thereof, the holding device 25 and the lower end of the control handle 21. The concealer 32 may be constituted by a small housing, for example in the form of a biconvex lens, as shown in Figures 1 and 2.
Fig. 4 viser en anden udførelsesform for opfindelsen, idet denne udførelsesform afviger fra den i figurerne 1 til 3 viste, ved at betjeningsgrebet 21's omdrejningsakse 22 her er vinkelret på planet af den af håndtaget 16 dannede ring. Også her kan en operatør, som holder håndtaget 16 med to hænder, aktivere betjeningsgrebet 21 ved hjælp af den ene eller den anden af sine to hænder, uden at slippe håndtaget 16.FIG. 4 shows another embodiment of the invention, this embodiment differs from the one shown in Figures 1 to 3 in that the rotational axis 22 of the control handle 21 is here perpendicular to the plane of the ring formed by the handle 16. Here, too, an operator holding the handle 16 with two hands can activate the control handle 21 by means of one or the other of his two hands, without releasing the handle 16.
Det er klart, at de ovenfor beskrevne udførelsesformer for opfindelsen udelukkende er beskrivende eksempler og på ingen måde er begrænsende, og fagmanden vil kunne foretage adskillige ændringer uden at bevæge sig uden for opfindelsens rammer. Eksempelvis kan den af håndtaget 16 dannede ring i stedet for at have form som et hjerte have andre former, som er kendte fra teknikkens stade. Desuden kan betjeningsgrebet 21 i DK 97 00247 U3 8 stedet for at være forbundet med en fordeler af hydraulikfluid være forbundet med en bremseindretning for hjulene 6.It is to be understood that the above described embodiments of the invention are merely descriptive examples and are in no way limiting, and those skilled in the art will be able to make several changes without departing from the scope of the invention. For example, instead of having the shape of a heart, the ring formed by the handle 16 may have other shapes known from the state of the art. In addition, instead of being connected to a hydraulic fluid distributor, the operating handle 21 in DK 97 00247 U3 8 may be connected to a brake device for the wheels 6.
