Description
Priprava za podpiranje in/ali privzdigovanje vozilaPreparation for supporting and / or lifting the vehicle
Izum se nanaša na pripravo za podpiranje ali privzdigovanje vozil, še zlasti na podporno nogo prikolice, zlasti počitniške prikolice, ali avtodoma ali podobnega vozila.The invention relates to a device for supporting or lifting vehicles, in particular the support leg of a trailer, in particular a caravan, or motorhome or similar vehicle.
Po mednarodni razvrstitvi patentov so izumi te vrste uvrščeni na področje mehanskih, še zlasti teleskopskih priprav za privzdigovanje ali podpiranje vozil na podlagi.According to the international classification of patents, inventions of this kind are classified in the field of mechanical, in particular telescopic devices for lifting or supporting vehicles on the ground.
Pri tem je izum zasnovan na problemu, kako zasnovati pripravo uvodoma omenjene vrste, ki bo obsegala karseda malo sestavnih delov.in bo temu ustrezno lahka, cenena in preprosta za izdelavo, navzlic temu pa bo primerna za uporabo v vsakršnih vremenskih pogojih.The invention is based on the problem of how to design the preparation of the aforementioned type, which will consist of as few components as possible. It will therefore be lightweight, cheap and easy to manufacture, however suitable for use in all kinds of weather conditions.
EP O 597 406 BI predlaga po višini nastavljivo podporno nogo, zlasti za avtodome. Tovrstna noga je pritrjena na šasijo vozila na proti podlagi obrnjeni strani in namenjena za podpiranje in po potrebi tudi za vsaj tolikšno privzdigovanje pripadajočega konca šasije, da je mirujoče vozilo na neravnem terenu možno privzdigniti v približno vodoraven položaj in ga v takem položaju podpreti, s čimer je omogočeno udobno bivanje v vozilu vključno s kuhanjem, pitjem iz kozarcev in podobno. Noga sestoji iz ogrodja s pogonskim sklopom in prigrajene zunanje cevi, v kateri je vstavljena notranja cev, tako da zunanja in notranja noga tvorita teleskopski sklop. Pogonski sklop sestoji iz pogonske gredi, ki je preko prenosnih sredstev povezana z vretenom, ki se nahaja v notranjosti omenjenih cevi, tako da je notranja cev vzdolž zunanje cevi teleskopsko premakljiva s pomočjo omenjenega vretena. Ogrodje je pritrjeno na šasijo vozila, zunanja cev pa je zasukljiva okoli omenjenega ogrodja oz. okoli pogonske gredi.. S tem dosežejo, da je podporna noga premakljiva iz horizontalnega položaja, ki je prikladnejši za vožnjo vozila, v približno vertikalni položaj, v katerem noga podpira vozilo med mirovanjem le-tega, ali obratno. Zasuk podporne noge iz enega v drug položaj s pomočjo vrtenja omenjene pogonske gredi, ki sicer zagotavlja omenjeno nastavljivost po višini oz. premikanje notranje cevi vzdolž zunanje cevi, dosežejo zahvaljujoč sojemalnemu vzvodu, ki je po eni strani pritrjen na omenjenem ogrodju, po drugi strani pa na robu notranje cevi. V ta namen mora biti zunanja cev opremljena z vzdolžno režo, ki dopušča dostop sojemalnega vzvoda do notranje cevi in je temu primemo oslabljena in mora biti zaradi zagotavljanja potrebne nosilnosti in uklonske stabilnosti temu primemo robustna. Sojemalni vzvod je okoli horizontalne osi zasukljivo pričvrščen na ogrodje in hkrati vzmetno podprt, tako da se ob zasuku gredi v eno smer notranja cev premika iz zunanje cevi, hkrati pa se celotna noga proti sili vzmeti premika iz horizontalnega v vertikalni položaj. Pri premikanju pogonske gredi v nasprotno smer se notranja cev pomika v zunanjo cev, na sojemalni element pritiskajoča vzmet pa omogoča sočasno premikanje noge nazaj proti izhodiščnemu horizontalnemu položaju noge. Poleg navedene robustnosti zunanje cevi in temu ustrezne teže, ki je pri opremi vozil vselej vredna pozornosti, se pomanjkljivosti znane podporne noge kažejo tudi v razmeroma velikem številu sestavnih delov, kar vpliva na zahtevnost in stroške izdelave, obenem pa tudi na zanesljivost delovanja, še zlasti ob upoštevanju dejstva, da je večina sestavnih delov med uporabo izpostavljena vremenskim vplivom, nečistočam in koroziji.EP O 597 406 BI proposes a height-adjustable support leg, especially for motorhomes. Such a leg is attached to the chassis of the vehicle on the opposite side of the vehicle and is intended to support and, if necessary, to raise the corresponding end of the chassis, so that a stationary vehicle on uneven ground can be raised to approximately horizontal position and supported in such a position. a comfortable stay in the vehicle, including cooking, drinking from glasses and the like. The leg consists of a driveline housing and an attached outer tube in which an inner tube is inserted so that the outer and inner legs form a telescopic assembly. The drive assembly consists of a drive shaft which is connected via transmission means to a spindle located inside said tubes so that the inner tube along the outer tube is telescopically movable by said spindle. The chassis is attached to the chassis of the vehicle and the outer tube is rotatable around said chassis (s). This ensures that the support leg is movable from a horizontal position which is more suitable for driving the vehicle to an approximately vertical position in which the support leg rests on the vehicle while it is stationary or vice versa. Rotating the support leg from one position to another by rotating said drive shaft, which otherwise provides said height or height adjustability. the displacement of the inner tube along the outer tube is achieved by the clamping lever, which is fixed on one side to said frame and, on the other, to the edge of the inner tube. For this purpose, the outer tube must be provided with a longitudinal slot that allows the suction lever to access the inner tube, which is thereby weakened and, in order to provide the necessary load-bearing capacity and buckling stability, must be robust. The pivoting lever is pivotally attached to the frame around the horizontal axis and spring-loaded at the same time, so that when the shaft rotates in one direction, the inner tube moves from the outer tube, and at the same time moves the entire leg against the spring force from horizontal to vertical position. When the drive shaft is moved in the opposite direction, the inner tube moves into the outer tube, and the pressure spring on the clamping element allows the leg to be moved back towards the horizontal horizontal position of the leg. In addition to the stated rigidity of the outer tube and the corresponding weight, which is always worthy of attention in the equipment of the vehicles, the disadvantages of the known support leg are also reflected in a relatively large number of components, which affects the complexity and cost of manufacture, as well as the reliability of operation, in particular Considering the fact that most components are exposed to weathering, impurities and corrosion during use.

Predlagana priprava za podpiranje in/ali privzdigovanje vozila po Sl. 1 in 2 sestoji iz okrova 1, v katerem je uležiščen pogonski sklop 2 z okoli vsaj približno horizontalne osi vrtljivo pogonsko gredjo 20, kot tudi iz teleskopske noge 3, ki je okoli gredi 20 zavihtljiva za vsakokrat želen kot, smotrno za vsaj približno ±90°.The proposed preparation for supporting and / or lifting the vehicle according to FIG. 1 and 2 consist of a housing 1 in which the drive assembly 2 is mounted with a rotating drive shaft 20 about at least about the horizontal axis, as well as a telescopic leg 3 which is rotatable about the desired angle about each time by a suitable angle of at least about ± 90 °.
Okrov 1 je prirejen za pritrditev celotne priprave na šasijo ali drug del vsakokratnega vozila in je v prikazanem primeru v osnovi zasnovan kot profil U. Pritrditev okrova 1 na vozilo je izvedljiva npr. s pomočjo ustrezne vijačne zveze, v splošnem pa po izbiri tudi drugače.The housing 1 is adapted to attach the entire chassis assembly or other part of the vehicle in question, and in the example shown is basically designed as a U. profile. by means of a suitable screw connection, and generally optionally otherwise.
Pogonski sklop 2 sestoji iz pogonske gredi 20 (Sl. 3 in 4), ki je okoli vsaj približno horizontalne osi vrtljivo uležiščena v okrovu 2. Na gredi 20 je nameščen in proti vsakršnemu zasuku glede na gred 20 v prikazanem primeru s pomočjo zatiča 210 za varovan stožčast zobnik 21. Omenjeni zobnik 21 je prirejen za sodelovanje s stožčastim zobnikom 22, ki je nameščen na vijačnem vretenu 25, ki se nahaja v notranjosti omenjene teleskopske noge 3, in priti vrtenju glede na vreteno 25 zavarovan z zatičem 220. Na ta način je ob vrtenju pogonske gredi 20 v eno ali drugo smer zahvaljujoč omenjenima zobnikoma 21, 22 omogočeno vrtenje vretena 25 v notranjosti noge 3 v vsakokrat ustrezno smer.The drive assembly 2 consists of a drive shaft 20 (Figs. 3 and 4), which is pivoted about at least about the horizontal axis in the housing 2. It is mounted on the shaft 20 and against any rotation relative to the shaft 20 in the example shown by means of a pin 210 for said conical sprocket 21. Said sprocket 21 is adapted to cooperate with a conical sprocket 22 mounted on a helical spindle 25 located inside said telescopic leg 3 and rotated relative to the spindle 25 secured by a pin 220. In this way the rotation of the drive shaft 20 in one direction or another thanks to said gears 21, 22 enables the rotation of the spindle 25 inside the leg 3 in the respective direction in each case.
Teleskopska podporna noga 3 sestoji iz primarne cevi 31, ki je vstavljena v omenjen okrov 1 in je s slednjim okoli pogonske gredi 20 zavihtljivo povezana, nadalje iz sekundarne cevi 32, ki je vstavljena v omenjeno primarno cev 31 in vzdolž slednje premakljiva, kot tudi iz končnega štrclja 33, ki je vstavljen v omenjeni sekundami cevi 32 in vzdolž slednje premakljiv.The telescopic support leg 3 consists of a primary tube 31 which is inserted into said housing 1 and is pivotally connected to the latter around the drive shaft 20, further to a secondary tube 32 inserted into said primary tube 31 and movable along said latter. of the end protrusion 33 which is inserted in said second tube 32 and is movable along the latter.
Omenjeni štrcelj 33, ki je vstavljen v sekundami cevi 32 in vzdolž slednje premakljiv, je na svojem prostem koncu 330 opremljen s podlogo 331, prirejeno za naleganje na vsakokratni podlagi, na nasprotnem t.j. v notranjosti sekundarne cevi 32 nahajajočem se koncu 332 pa z navojno pušo 333, kije prirejena za sodelovanje z vijačnim vretenom 25.Said nozzle 33, inserted within seconds of the tube 32 and movable along the latter, is provided at its free end 330 with a liner 331 adapted to be supported on each base, on the contrary i.e. inside the secondary pipe 32, located at the end 332, with a threaded sleeve 333 adapted to cooperate with the screw spindle 25.
Sekundama teleskopska cev 32, v kateri je vstavljen omenjeni štrcelj 33, je vstavljena v primarni teleskopski cevi 31 in vzdolž slednje premakljiva skupaj z v njej vstavljenim Šircljem 33. V ta namen je sekundama cev 32 na notranjem, proti ogrodju 1 štrlečem koncu 321 opremljena z navojno pušo 322, ki je prirejena za sodelovanje z vijačnim vretenom 25, kot tudi z nasedoma 323, 324 (Sl. 6), ki sta prirejena za sodelovanje z odmičnima vzvodoma 11, 12, ki bosta podrobneje opisana v nadaljevanju. V prikazanem primeru je zunanja površina 325 sekundarne cevi 32 sicer razmeroma razčlenjena, vendar je smiselno po celotnem obodu in po celotni dolžini prirejena notranji površini primarne teleskopske cevi 31, kar pripomore k izvrstnemu vodenju sekundarne cevi 32 vzdolž primarne cevi 31.Secondarily, the telescopic tube 32, in which said projection 33 is inserted, is inserted into the primary telescopic tube 31 and, along the latter, is movable together with the inserts 33. For this purpose, the tube 32 is provided with a threaded end 32 on the inner, towards the frame 1 of the projecting end 321. bushing 322 adapted for engagement with the screw spindle 25, as well as the bushings 323, 324 (Fig. 6) adapted for engagement with the camshafts 11, 12, which will be described in more detail below. In the example shown, the outer surface 325 of the secondary tube 32 is relatively disaggregated, but makes sense along the entire circumference and along the entire length of the inner surface of the primary telescopic tube 31, which contributes to the excellent guidance of the secondary tube 32 along the primary tube 31.
Primarna cev 31 (Sl. 5) je z okrovom 1 povezana na tak način, da je zasukljiva okoli pogonske gredi 20. V ta namen je primarna cev 31 opremljena z ušesoma 311, 312, ki segata v območje okrova 1, omenjena pogonska gred 20 pa poteka skozi odprtini 31Γ, 312' v omenjenih ušesih 311, 312. Med omenjenima ušesoma 311, 313 primarna cev 31 obsega prečno steno 313 z odprtino 313' za prehod vretena 25. Neposredno nad omenjeno steno 313 se nahaja stožčasti zobnik 22, neposredno pod omenjeno steno pa podložka 250, ki je na vijačno vreteno 25 pričvrščena s pomočjo zatiča 251.The primary tube 31 (Fig. 5) is connected to the housing 1 in such a way that it is rotatable around the drive shaft 20. For this purpose, the primary tube 31 is provided with ears 311, 312 extending into the area of the housing 1, said drive shaft 20. and passes through openings 31Γ, 312 'in said ears 311, 312. Between said ears 311, 313, the primary tube 31 comprises a transverse wall 313 with an opening 313' for the passage of the spindle 25. Directly above said wall 313 is a conical gear 22, directly below said wall being a washer 250 which is secured to the screw spindle 25 by means of a pin 251.
Nadalje sta na osi 10, ki je vgrajena v omenjenem okrovu 1 neposredno ob omenjenih ušesih 311, 312 primarne cevi 31 in ekscentrično glede na vzdolžno geometrijsko os pogonske gredi 20, zasukljivo nameščena odmična vzvoda 11, 12, ki sta vstavljena v primarni cevi 31 in prirejena za sodelovanje z omenjenima nasedoma 323, 324 na čelni ploskvi notranjega konca 321 sekundarne cevi 32.Further, on the axis 10, which is mounted in said housing 1 directly adjacent to said ears 311, 312 of the primary tube 31 and eccentrically with respect to the longitudinal geometric axis of the drive shaft 20, the camshafts 11, 12 which are inserted in the primary tube 31 and adapted to cooperate with said two strands 323, 324 on the face of the inner end 321 of the secondary pipe 32.
Kot rečeno, je omenjeno vijačno vreteno 25 preko stožčastih zobnikov 21, 22 povezano s pogonsko gredjo 20. Ko je priprava z ogrodjem 1 pritrjena na vozilu, se med vožnjo vozila noga 3 nahaja v približno horizontalnem položaju po Sl. 7. Noga 3 je v tem položaju držana zahvaljujoč v okrovu 1 ekscentrično glede na pogonsko gred 20 na osi 10 uležiščenima odmičnima vzvodoma 11, 12, proti katerima je v območju nasedov 323, 324 na svoji proti okrovu obrnjeni čelni ploskvi s pomočjo vretena 25 pritisnjena sekundama cev 32As mentioned, said helical spindle 25 is connected via a bevel gear 21, 22 to the drive shaft 20. When the device with the frame 1 is attached to the vehicle, the foot 3 is in a roughly horizontal position according to FIG. 7. The leg 3 is held in this position thanks to the housing 1 eccentrically with respect to the drive shaft 20 on the axis 10 by the camshafts 11, 12, against which, in the area of the seats 323, 324, the front surface facing the housing is pressed by the spindle 25. seconds pipe 32
Ko vozilo miruje, ga je možno s pomočjo priprave po izumu podpreti ali privzdigniti na tak način, da nogo 3 postopoma premaknemo v vertikalni položaj po Sl. 7, kar dosežemo z vrtenjem pogonske gredi 20 in s tem vretena. Zahvaljujoč vrtenju gredi 20 in vretena 25 se sekundama cev 32 prične premikati vzdolž primarne cevi 31 v smeri vstran od okrova 1, obenem pa se pritisk proti odmičnima vzvodoma 11, 12 postopoma zmanjšuje, kar potem dopušča zasuk noge 3 okoli gredi 20 iz horizontalnega položaja proti vertikalnemu položaju. Na Sl. 7 je ponazorjen eden od vmesnih položajev noge 3, v katerem sekundama cev 32 že do določene mere sega iz primarne cevi 31, posledica deloma sproščenega pritiska na odmična vzvoda 11, 12 pa je približno 45-stopinjski zasuk noge 3. Še preden sekundama cev 32 dospe v končni položaj štrlenja iz primarne cevi 31, se noga 3 nahaja v približno vertikalnem položaju, kot posledica še nadaljnjega vrtenja vretena 25 pa se šele potem iz sekundarne cevi 32 po potrebi prične pomikati še štrcelj 33, kar vsekakor kaže na izjemno široke možnosti izbire vsakokrat potrebne dolžine noge 3.When the vehicle is stationary, it can be supported or lifted by the device of the invention in such a way that the leg 3 is gradually moved to the vertical position according to FIG. 7, which is achieved by rotating the drive shaft 20 and thereby the spindle. Thanks to the rotation of the shaft 20 and the spindle 25, the tube 32 begins to move along the primary tube 31 in the direction away from the housing 1 in seconds, while gradually reducing the pressure against the camshafts 11, 12, which in turn allows the leg 3 to rotate from the horizontal position towards vertical position. In FIG. 7 illustrates one of the intermediate positions of the leg 3, in which the pipe 32 extends to a certain extent from the primary pipe 31, resulting in a partially relaxed pressure on the camshafts 11 and 12 results in approximately a 45-degree rotation of the leg 3. Even before the seconds pipe 32 reaching the final projection of the projection from the primary tube 31, the leg 3 is in an approximately vertical position, and as a result of the further rotation of the spindle 25, the projection 33 begins to move further from the secondary pipe 32 if necessary, which certainly indicates extremely wide choices each leg length required 3.
Poleg navedenega se prednost predloženega izuma kaže tudi v preprosti in ceneni izdelavi sicer razmeroma maloštevilnih delov priprave. Z izjemo pogonske gredi 20, vijačnega vretena 25 in osi 10 z odmičnima vzvodoma 11, 12 ter zatičev 210, 220, 251 so namreč vsi preostali deli okrova 1 in noge 3 vključno z zobnikoma 21, 22 pogonskega sklopa izvedljivi iz termoplastične mase, kar je ugodno tako z vidika korozijske obstojnosti kot tudi z vidika preproste in cenene serijske proizvodnje. Dasiravno je predvideno, da so pogonska gred 20, vijačno vreteno 25 in os 10 z odmičnima vzvodoma 11, 12 ter zatiči 210, 220, 251 izvedeni kot kovinski deli, so ti z vidika izdelave prav tako povsem nezahtevni in povrhu vsega izvedljivi npr. bodisi iz nerjavnega jekla ali iz katere od lahkih kovin ali njihovih zlitin, zato so lahko razmeroma lahki in tudi korozijsko obstojni.In addition, the advantage of the present invention lies in the simple and inexpensive manufacture of otherwise relatively small parts of the preparation. With the exception of the drive shaft 20, the screw spindle 25 and the axle 10 with the camshafts 11, 12 and the pins 210, 220, 251, all the remaining parts of the housing 1 and the legs 3 including the gears 21, 22 of the drive assembly are feasible of thermoplastic mass, which is favorable both in terms of corrosion resistance and in terms of simple and inexpensive batch production. It is envisaged that the drive shaft 20, the screw spindle 25 and the axle 10 with the camshafts 11, 12 and the pins 210, 220, 251 are made of metal parts, which, from the point of view of manufacture, are also quite difficult and, above all, feasible, for example. either stainless steel or any of the light metals or their alloys, they can be relatively lightweight and also corrosion resistant.
