PATENT OFFICE PATENT SPECIFICATION No. 248963 class: 81 b lnt. CIB 65 g expenditure day: 25. August 1966 ADMINISTRAT R width unit ST IN VA Z stacker truck for hand enterprise announced on 11-May 1964 (A 4092/64): Priority of the Aumeldung in France of the 12.Mai 2963 R. 934529) stresses. Beginning of the patent duration: 15.Dezember 1965. The invention refers sees to a stacker truck NR hand enterprise, whose chassis exhibits except the main carrying wheels before this attached Sttltzrollen and possesses vertical Gleitftlhrungen, along which one platform od.dgl, for the admission of the load by means of a hydraulic, by hand controllable lifting mechanism is perpendicularly adjustable. In the case of the well-known Hubstaplem of this design the disadvantage that the stacker truck is obstructed by in front the firmly arranged supporting rollers, at good one which can be loaded resulted to be brought, in order to raise it, if an accordingly high area is not kept free here, in which both the front Sttltzrollen and the Ladeplattform place finds. This disadvantage is avoided in accordance with the invention with Hubstaplem of the mentioned design thereby that the two main wing unit sit at a transverse axis appropriate in the proximity of the vertical sliders and the Sttltzrollen present before the carrying wheels sits at before-rising up mobile arms, by means of which it into one scarcely before the Haupttragrädem situation present withdrawable is. Thus ftlr the Unterfahren of the load is made smaller by the Ladeplattform necessary area. By the Zurtlckziehen of the front Sttltzro! len remains the stability of the stacker truck existing, since this front Sttltzrollen is appropriate for that also in the withdrawn situation still before the bearing positions main wing unit and thus the stacker truck on four points being because of the corners of a trapezoid aufmht. Further characteristics and advantages of the invention come out from that below on the basis the designs erläutesten Ausftlhrungsbeispiel. In the designs a preferential Ausftlhrungsform of the invention is for example represented. Then are Fig. 1 a side view of the entire stacker truck, Fig. 2 a Vordemnsicht of the article of the Fig. 1, Fig. 3 a partial section along the line [...] III in Fig. 9. in larger yardstick, Fig., 4 a partly cut opinion of the article of the Fig. 3, from above, in the Scbmitt along the line IV-IV in Fig. 8, Fig. 5 a partial section of the longitudinal axis of the stacker truck, in particular for the illustration of the Aatriebsmechanismus for the mobile platform, Fig. 6 a cut along the line VI-VI in Fig. 5 in larger yardstick, Fig. 7 a detail opinion for the illustration of a Festste! lorganes ftlr the mobile platform and Fig. 8 an opinion of the article of the Fig. 7 in by the Pfei! VIII characterized line of sight. The chassis of the stacker truck consists those of an axle 10, at each end to a Aehszapfen 11bzw. 12 is extended. the per one of the carrying wheels 13, from a vertical container body the admission of a Druckmirtels, which is welded ia the center of the axle 10, carries 14 r and from a vertical Ftlhmngsträger, which is firmly connected by a connecting link 15 with the upper end of the container body 14. The Ftlhrungsträger exhibits two vertical Gleitftlhmngen 16 and 17, which are connected by means of horizontal rungs 18, among themselves 19.20. The intermediate rung 19 is welded at the connecting link 15, and the lower rung 20 is at horizontal carrying members 2! angesehweißt, which are welded for their part at the axle 10. Between the rungs! a FUhmngsglied 28, which is in same distance from the Gleitfllhtungeu RST and 17, extends 8 and 19 and exhibits a vertical groove 24. - 2 - N 248963 Fahrgestelldes the Hubstaplerswi_rd at the rear side through in-hurry Tragrahmea 25 completed, which is equipped with one into arbitrary direction schwentd arene rear raw one 26, which is montfett in the framework 25 by means of a tlbl2chen absorber mechanism for example a feather/spring or a hydraulic absorber, so that the role of 26 is able, igkeiten due to Unregelm the AufIagefläche when driving around the stacker truck arising impacts to take up. The support frame 25 is fastened b i 27 and 28 to the container body. For the guarantee of a reliable equilibrium of the stacker truck with loading and/or during load and increased safety in the enterprise zttt is an arrangement of withdraw-asked Vordermllen (Fig. planned 3 and 4), which consists of an u-shaped framework, that from one to the wave! 0 parallel Querglted 29 of square cross section and two arms 80 exists; at their free end the per one ¥orderm!! e 8I carry. The arms 80 are has of two upper forks 32 at the same time adjustably, which are tiltable installed onto the axle pivots 11 and/or 12. The movement distance of the zurtlckziehbaren u-shaped framework 9.9, 30 in the Rahmengliedem 82 is limited through front attack 33 and rear Ansctdäge 84, which are firmly connected with the arms 30. The QuergHed 29 is with two Schwenklagemrangen 85 (Fig. 2 and 3) equipped, in which a Horizoutalstrebe 36 is tiltable stored, which is firmly connected with two arms 37 and forms with these together a triangle, its point with 27 at the container body 14 (Fig. 1) is eye-guided. Owing to this arrangement the framework can take 29.30 two positions, i.e. one in Fig. for 1 position represented in full lines in that the v, orderen roles of 31 stand before the carrying wheels 13 find and the stability of the stacker truck secure, WAD second, in Fig. ! in interrupted lines represented Stelhmg in that the roles of 8! zurtlekgezogen themselves are and around a slight measure in zurUckgezogeuer position opposite the Tragrädem! 3, “however still before their axle finds. The Anordntmg, those the establishment of the zuruckziehbaren front roles of 3! in the shoved out position as well as their Enttiegelung ftlr the 7.urackziehen made possible, is in Fig. 3 and 4 veranschau/2cht WAD consists of a Pedal40, which is arranged below the same ha of the center of the axle 10 of the car and is stored around an axle 41 ineineman the axle 10 fastened articulated bearing block 42. The pedal 40 is equipped from a baseplate 43 for the swivelling of the pedal with the foot, a camp 44 for the admission of the transverse member 29 of the framework to carrying the roles of 31, furthermore with a vertical edge 45 to the Zurtlckstoßen of the prop 36 and the Quersttlkkes 29 to the rear with the occurrence on the baseplate 43 to the Entfiegeln of the withdrawable framework 99,30. The represented pedal 40 exhibits furthermore an attack 46, which is intended for it, against the lower surface of the axle 10 anzastlltzen themselves, so that it limits the downward turning of the pedal with its manipulation, and one out curvature 47, which is certain to the attack at the rear vertical surface of the axle, in order to limit the Bewegtmgssttecke of the Rllekkehrhewegung of the pedal when releasing the baseplate 43. A Rüclfftlhrfeder 48, those with their an end at the axle 4! befesrigtistund with their other end the lower surface of the axle 10 drove on, is anxious, the pedal against the Ub_tzeigersinn to swivelled (Fig. 3), if one vorderert roles 31 those against an obstacle knock against, zurttckziehen wants, gentlgt it, to step on the baseplate 43 in order to swivel the pedal in the clockwise direction around those axle 42 against the effect of the feather/spring 48. The storage 4z releases then the transverse member 29, and the vertical edge 45 shifts the prop 36 and the transverse stack the 29 so far to the rear that with the Weßterschleben of the stacker truck the obstacle arranges the roles of 31 to withdraw itself as the arms 30 in the forks 32 shift. Around the roles of 3! again to shove out, it gentlgt, to forward-push daz transverse member 29 mk the Euß until it inserts itself again into its storage 44, with what the Vertiegelung in ausgeschoheuer position of the roles of 3! is ensured. On the carrier of the Gleitftlhmngen 16 and 17 ha is installed vetti.kal a slidingable-capable mobile organ, that in Fig. 2 with 50 is characteristic. This mobile organ 50 consists of a vertical framework 51, which is equipped with vertical slots on its rtlctcvvärtigen part, which cooperate with the Gleitfllhrungen 16und 27, and exhibits a platform 52, which is in such a manner tiltable stored at the framework 51 by means of a Schamieres 53 that it can be lifted into the vertical position. In the level of the vertical framework 51 is 55 linking arm at of 54 linked. This laying out arm 54 makes the use of the mobile organ for A possible! s arm for loading with for example Drahtbtlnde! n, like in interrupted lines in Fig. 2 above, gesture of! as per around this the arm arm will reach 54 brought into the horizontal and so far raised the platform 52 that it stands to the framework 51 parallel. The arm arm 54 and the platform 52 incoming goods then by means of any well-known (not represented) high-speed bolting device firmly connected. With the Ven¢endung of the mobile organ 50 in Fig. 1 position, thus during horizontal arrangement of the platform 52, represented in full lines, is fllr the loading and fttt carrying loads a Hilfsverriegelungseinrichmng intended, which makes possible it to strengthen the fixed connection between that platform 52 and the framework 51 and to thus increase security with seizing or placing of loads on the platform 52. This bolting device means is in particular in Fig. represented, and that consists 7 and 8 sehwenkbar around an axle 57 at one of the outside vertical members of the vertical framework 5 of a hook 56! is fastened. This hook 56 is in such a way gekrtlmmt that it arbietet a horizontal counter bearing surface 58 D, on that the Unterflache of the flat - form 52 in particular in Fig. 7 represented way rests. As evident, the platform 52 not by turning around the Schwenldager 53 against the framework 51 can fold itself in the locked position of the hook 56, and this represents an important Sichesungsmaßnahme. The hook wttd in Fig. 7 and 8 represented position of a Blatffeder 59 held, which is fastened to the inside of the hook by means of a screw 59° and whose free end is abgesttltzt against the outside vertical member. In order to solve the fixed connection between the platform 52 and the framework 51, it, on the top of the hook 56 is sufficient to out-rave against the effect of the leaf spring 59, a pressure. The Vertikalversehiebung of of the mobile organ 50 takes place under the drive via a Seilscheäbe 60, which is swivelling installed around an axle 61 in a fork 62, which is rigidly connected to that with a Kude a piston rod 63 of of a hydraulic hoist, which slides in a vertical hydraulic cylinder 64, for the carrier of the Ftlhrungen 16 and 17 is parallel and at the intermediate rung! 9 by means of a Sehelle 65 and to the lower rung 20 by means of a clip 66 is fastened, what latter by means of screws 67 is fastened. The cylinder 64 is in the same axle as the groove 24 of the driving member 23 of the Gleitfllhmngstxägers, and the end of 68 of the axle 61, which carries the quadrant 60, is firmly gefllhrt in this groove 24, so that the piston rod 63 when shoving out from the hydraulic cylinder 64 is continuously geftlhrt and cannot from the axle of the stacker truck not depart. In the Seilrille of the Seilsche£be 60 eLu rope 69 is inserted, its end with 70 in the connecting link! 5 firm driving gesture! the les stacker truck (Fig. 5), during its other end is fastened with 7! to one of the vertical members of the vertical framework 51 of the mobile organ is fastened. The drive of the hydraulic hoist 64 is in particular from Fig. 5 and 6 evidently. The cylinder 64 is at the container body! 4, which is gettlllt with a Dmclmaittel, for example oil, by means of a piping 75 attached, which is attached at the cylinder 64 by means of a screwing sleeve 7ö and ends at a valve body 77, which is fastened by means of screws 78 to the wall of the container body 14. This valve body 77 is to a pump 79, which dived into the argument inside the container body 14, sees attached however in a distance from its ground finds. The valve body exhibits a longitudinal channel 80, into some Dmckmittelzuleitung 8! fllr the cylinder 64 and a Druckmittelaustrittsleßtung 83 ftlr the cylinder 64 munden. These two lines are by the pressure medium reservoir! 4 hindurchgefi] hrt and mtlnden into the pump 79. The line 81 stands itself for the pump with an axial channel 89, 79 in connection, while the Lei tung to 83 see with a Qnerkanal 84 leading in connection rules, that to the Axia! line 89 under rechrem angle " extended, however in the same level as the latter is not. The line 82 is open at their two ends, however their lower Mtlndung is by means of one with 82 ' schematically angedenteten throttle valve lockably, while the connection between the piping 8! and the line 82 with one with 8! “is equipped schematically suggested one-way valve. If one feeds an argument ha the line BP, around this the cylinder Ot zuzufllhren, pushes the pressure of the argument the valve 89” against its seat and takes off the closing link of the valve 81 ', so that the line 8 and the hose 8! leading in connection to be brought. During the pressure at the line 89. Zero become, if thus the cylinder does not become 64 any more fed wixd, the closing link of the valve 8! 'under the effect of the pressure of the argument in the hose 8! against its seat pushed. The transverse channel 84 flows at the lateral surfaces of the pump and stands with the inside of the container! 4 leading has of connection. Into suitable recesses in the valve body 77 and the pump 79 inserted seals 85 ensure the close conclusion of the device. The Dmckmittel is displaced out of the container body 14 into the cylinder 64 by means of a pump 79, which is propelled by means of a piston rod 90, which is stored in the upper TeüdesBehälterkörpers 24. This is suited 90 is by the upper screwed on cover 91 through goes, which locks the Behältexkörper 24. The close conclusion between the piston rod 90 and the cover 91 mash perfectly its, thus the Ö! “not from the container out-seep and the close catch can in arbitrary bskannre,} way posed, for example by means of a poetry be obtained however not there. In its top the piston rod 90 exhibits a longitudinal recess 92, it made possible, if one lowers dia. piston rod 90, to set in order to make a penetration possible of the lower part of these Ausspamng in the Behälrer 14, the inside of the container with more.der going around air in connection. With each downward stroke of the piston rod 90 for feeding a certain Dmckmitteknenge from the container 24 into the cylinder 64 in the container 14 a counter ceiling is produced, which would know the perfect functioning of the hydraulic device beeintzächrigen. If however the recess 92 sets the inside of the container with the atmosphere in connection, air can enter, and the danger of a Unterdmckes in the container is ausgescha! - tet. In a state of rest nat [lrlich the recess 92 completely outside of the container 14 must be and in a distance from this (Fig. 5). This is obtained by the construction of the descriptive device. The piston rod 90 is at its outside end with 93 at a lever of L-shaped Ausbüdnngangelangt, which exhibits a long operating arm 94 and a firmly associated short arm 95. The short arm 95 is linked by means of a tap 96 at eirier prop 97, which is tiltable stored around a firm axle 98, those in the connecting link 15 the driving gesture! the les stacker truck eye rdnetist.DerBetätigungsarmist, wieausFig.5ersichtiich dauerndmitte1seinerRü more deder 99 in-one-upper position zurtiekfflhrbar, and these feather/spring is angestützt around those axle 96 towards probes and with their an end to the lnnenfläche of the short arm 95, while you have other end at the prop 97 their counter bearing. In this way the feather/spring 99 endeavors to remove the arms 95 and 97 from each other and bewkkt thereby their Schwenknng around the axle 96. Auf diese Weise'befindet itself the Ko! - is benstange 90 in a state of rest in the elevated position within the container 14, and the recess 92 in a distance above the cover 91. DerHydraulikant.rieb completed by a EntleemngsventiI for the cylinder 64, which consists of a screw 100, their threads in a Irmengewinde 101 in the top of the longitudinal channel 80 of the Venfilkörpers 77 larger in the diameter intervenes. This screw 100 serves what latter for the establishment of a ball 102 on its seat, on the height of the hose 83 is, so that the ball 202 locks this hose 88. Tightening and/or Lösen'der screw 100 takes place by means of a bar 108, which by means of a clip 104, which is held along the container body 26 and ends in a Betätigungslmopf 105. Between this operating knob 10 and the clip 104 the bar is surrounded, the release relieved 108 by a feather/spring 106, since it is effective in the same sense (Fig. 1). If one wants to lift nnn the mobile organ 50, to thus operate the hydraulic hoist 64, one must bring the ball to 102 to that she locks the hose 83, by screwing the screw in 100. Then one can take the pump 79 in enterprise and feed the cylinder 64, by schwenten the lever 94 from top to bottom wants one the mobile organ 0 to lower, is sufficient it, to loosen the screw I00 so that the ball 102 does not lock the hose 83 for no more. The mobile organ 50 bewkkt by its Eigeagewicht that the piston 63 in the hydraulic hoist 64 is abgesengt and the argument by the line 75, by which 4 channel 80 of the Venfilkörpers is displaced and by the Quexlmnal 83 into the container body I4. Finally it is to be noticed that the whole stacker truck is maneuverable amels an approximately horizontal dyke el 110, which is tiltable stored around an axle I2I in a fork I12. with the upper rear end of the Behälrerkörpers 14 is firmly connected. The cheeks of the gift! 112 exhibits a number of holes 8 in circle-arc-shaped arrangement, some Verriegeinng of the pole 1! 0 in different intermediate positions between a horizontal and a vertical position permit. The pole 110 lets itself adjust upward into the vertical situation, so that by Vsrmindexung of its space requirement of the stacker trucks also is maneuverable with particularly limited spatial relations. For this purpose the internal end of the pole with two insertable is, normally protrude-loads rest pins 114 equipped, those into appropriate holes I13 of the fork 112 intervenes and the pole] 20 in Fig the I and 5 in vo! len lines represented horizontal position or in an intermediate position lock. By impressions of these rest pins 114 these are unlockable from the punches, so that one then the pole in dash-dotted lines in Fig. 5 represented vertical position to bring can do. The manipulation with the loosening of the rest pins 114 can do of a distant place, for example by the outside end of the pole 1] 0 out, and with the rest pins 114 with arbitrary means, for example by means of a bowden cable, fastened by means of one to the pole, takes place, withdrawing the rest pins 114 effectuation, if the release lever is operated.
