Definitions

• the present invention relates to an apparatus for the lat ⁇ eral tilting, or rolling, of a vehicle, comprising an arc ⁇ uate support rail disposed at each vehicle axle, the rails being intended to roll on a substrate and being provided with a lower portion extending beneath the vehicle and a side portion extending at least partly along- one vehicle side, the support rails being securable in the vehicle and interconnectible with one another via a bar extending in the longitudinal direction of the vehicle.
• Apparatuses of this type are previously in a plurality of different designs, for example from SE-B-365 487, DK-B-149 254 and GB-930 486.
• the designs and constructions ac ⁇ cording to these prior publications share, as a common feature, an arcuate support rail which extends in beneath the vehicle and is secured to the vehicle in such a manner that the vehicle, together- with the support rails, may roll laterally so that thereby the underside of the ve ⁇ hicle is made accessible for, for example, repairs.
• the prior art apparatuses suffer from a common drawback in that at least two and, in certain cases, all four vehicle wheels must be dismounted, and so the vehicle must be shored up before the support rails can be' mounted on the vehicle. Naturally, this entails a circumstantial and, in certain cases not entirely risk-free mounting procedure.
• the support rails be provided with engage ⁇ ment devices specially adapted for each vehicle model, the engagement devices abutting against bearing parts in the vehicle body. This circumstance renders this embodiment particularly complex and roundabout to use.
• the present invention has for its object to devise an ap ⁇ paratus of the type mentioned by way of introduction, the apparatus being designed in such a manner as to permit simple and ready securement on the vehicle, without the need for the vehicle to be lifted separately and shored or supported on blocks before mounting can take place.
• the present invention has for its object to realise an ap ⁇ paratus which permits driving-up of the vehicle onto the apparatus and rapid and simple interconnection between the vehicle and the apparatus.
• the present invention also has for its object to realise an apparatus which permits tilt ⁇ ing in any optional direction.
• the invention also has for its object to realise an apparatus which does not prevent opening and closing of vehicle doors when the ve ⁇ hicle is in position in the apparatus.
• each support rail has support members on which the wheels of the vehicle may be driven and secured; and that, for the drive-onoperation, the support rails are provided with portions disposed beneath the support members, the portions being dismount- able or switchable between such positions that, in the one position the support members are located close to the driving substrate, and in the second position the support members are located a distance from the substrate for lat ⁇ eral tilting.
• the support rails also suitably each include approximately semi-circularly curved rails to whose ends are connected mutually approxi- mately parallel upper shanks or bows between which the ve ⁇ hicle is intended to be located, and a transverse strut is secured in the curved rails, the strut being approximately normal to the upper shanks and carrying the support mem ⁇ bers, the portions of the support rails located beneath the transverse strut constituting the dismountable or switchable portions.
• the portions of the support rails loc ⁇ ated beneath the transverse struts are dismountable.
• the portions of the support rails located beneath the transverse struts are pivotally sec ⁇ ured via hinges with pivot axes which are roughly parallel to the transverse struts.

• reference numeral 1 refers to a substrate which may be a workshop floor but could just as well be a surface outdoors.
• Reference numer ⁇ al 2 refers to a vehicle, reference numerals 3 and 4 to the forward and rear support rails, respectively, ref ⁇ erence numeral 5 to a lower longitudinal bar and reference numeral 6 to an upper longitudinal bar.
• a wedge shaped drive-on ramp 7 rests on the substrate 1 and, beneath the vehicle, running ramps 8 and 9 which may be insertable in one an ⁇ other for adjustment of length.
• the wheels 10 and 11, res ⁇ pectively, of the vehicle rest on support members 12 in the form of plates beneath the wheels 10 and 11.
• both the drive-on ramp 7 and the running ramps 8 and 9 are ideally duplicated so that one set of ramps is disposed beneath the left-hand wheel pair of the vehicle, while a corresponding set of ramps is disposed beneath the right-hand wheel pair.
• the ramps may be made of sheet metal material of approximately U-shaped, downwardly open profile, and may be of such di ⁇ mensions that they may be telescopically inserted in one another for length adjustment and for compact storage.
• the forward and rear support rails 3 and 4 are anchored in the lower longitudinal bar 5 and adjustable in the longitudinal di ⁇ rection thereof in that the support rails are connected with sliding sleeves 13' and 14, respectively which are shiftable along the bar 5 and lockable in optional pos ⁇ itions therealong.
• the support rails 3 and 4 are provided with upstanding upper shanks 15 and 16, respectively, disposed on either side of the vehicle 2 and, via sliding sleeves 17 and 18, securable in optional positions along the upper, longitudinal bars 6. It will further be apparent from Fig.
• the apparatus according to the invention has, in the position illus ⁇ trated in the Figure, its support members 12 located at relatively low height above the substrate, whereby the construction height of the ramps 7-9 may be considerably reduced.
• This entails a simple drive-on of the vehicle.
• the support rails 3 and 4 are provided with lower portions 19 and 20 which are either dismount- able from the remaining parts of the support rails or are pivotally connected thereto at positions beneath the sup ⁇ port members 12 and, preferably, also beneath transverse struts 21 which carry the support members 12.
• the lower portions 19 and 20 are secured via hinges 24 which have pivotal axes transverse in relation to the longitudinal direction of the vehicle and are preferably approximately parallel with the above-mentioned transverse struts 21 (see Fig. 3) .
• the apparatus is provided, in both the forward and rears -ends thereof, with an anchorage 22 for cooperation with a lifting device 23, ideally a conventional garage jack.
• the anchorages 22 may, for example, be insertable in for- ward and rear ends of the lower longitudinal bar 5.
• anchorages 22 extend upwardly so as to be located at a greater distance from the substrate 1 than, the- longitudinal bar 5 so -that thereby sufficient space will be created for the lifting device 23, and so that tilting of the apparatus to the position illustrated in Fig. 2 will not result in the anchorage coming into direct contact with the substrate 1 or the distance to the substrate becoming so slight that there is insufficient room for the lifting device.
• the garage jack 23 is simply moved into engagement with the rear anchorage 22, where ⁇ after the lower portion 20 is pivoted down and locked in the rear support rail 4.
• the vehicle stands on an approximately semi-circularly curved rolling path at least partly formed by the two lower portions 19 and 20 of the support rails 3 and 4.
• the lower portions 19 and 20 may be connected to a transverse stay 25 (see Fig. 3) which is lockable in the lower portions but also dismountable or pivotal in relation thereto.
• transverse stay 25 use may, of course, be made of conventional shoring props or blocks to prevent unintentional lateral overturning of the vehicle.
• the support rails 3 and 4 are approximately semi-circularly curved, with the centre of curvature located at a height approximately 20- 30 cm above the average axle height of a normal vehicle.
• This dimensioning of the apparatus according to the pres ⁇ ent invention entails that the centre of curvature of the support rails 3 and 4 will approximately coincide with a horizontal line passing longitudinally of the vehicle through the point of gravity thereof. Hereby, that force which is required for lateral tilting of the vehicle will be minimal.
• the arcuate, or at least approximately arcuately curved, portions of. the support rails 3 and 4 extend up partly along the vehicle sides where they merge in the upper shanks 15 and 16. These upper shanks are of such a height that both of the upper, longitudinal bars 6 will be located above that space which is required for opening and closing the doors of the vehicle.
• trans ⁇ verse strut 21 is rigidly connected to side portions of the support rails 3 and 4 beneath the lower end regions of the side shanks 15 and 16.
• the support members 12 are shiftable in the longitudinal direction of the transverse strut 21 by the intermediary of sliding sleeves 26 on which support plates 27 for the wheels are secured.
• the support plates 27 are provided, on their inner sides fac- ing the centre of the vehicle, with upstanding slip guards 28 which are intended to cooperate with side surfaces on the vehicle wheels and thereby prevent the vehicle from sliding in the longitudinal direction of the transverse strut in connection with tilting.
• chocks 29 For anchoring the vehicle in the apparatus according to the invention, use is made of clamping belts or locking catches which cooperate with the support members 12 and which positively urge the vehicle wheels 10 and 11 against the support members by engagement with the wheels.
• suitable chocks 29 See Fig. 2 which prevent the vehicle wheels from rolling in the longitudinal direction of the vehicle.
• these chocks are securable in the support plates 27 of the sup ⁇ port members 12.
• anchorages 30 flush with the wheel hubs and at least on one side of the apparatus, in which anchorages support portions 31 are ad ⁇ justably secured so that they may be brought into lateral abutment against the rim or wheel hub.
• the support por- tions are adjustable in the horizontal direction for adap ⁇ tation to different vehicle types and the position of the vehicle in the apparatus according to the invention.
• the hinges 24 are also possible according to the invention to place the hinges 24 higher up or immediately on the under ⁇ side of the transverse strut 21.
• the distance from the substrate 1 to the upper side of the support members 12 when the pivotal portions 19 and 20 are pivoted to horizontal positions will be so slight that separate drive-on ramps 7 are no longer needed.
• the support members 12 are instead provided at both ends with oblique downwardly directed ramp surfaces which replace the drive-on ramps.
• Fig. 4 illustrates a modified embodiment of the apparatus according to the present invention in single-sided de ⁇ sign.
• this em ⁇ bodiment like the embodiments described above, is pro ⁇ vided with forward and rear support rails 3 and 4, res- pectively, only the forward rail being shown in the Fig ⁇ ure.
• These support rails are provided with upper, sub ⁇ stantially straight and - in the illustrated position - approximately vertical upper shanks 15, and an approxi ⁇ mately arcuately curved portion 32 which connects with the lower end of the shanks 15 and which merges in a substan ⁇ tially straight portion 33 which is shown in the Figure as lying horizontally on the substrate 1.
• the curvature of the curved portion 32 lies in the order of magnitude of 90 * .
• the curved portion 32 and at least one lower portion of the upper shank 15 are provided with a reinforcement 34 which increases flexural rigidity in this area.
• the tran ⁇ sverse strut 21 extends out horizontally from the lower portion of the reinforcement 34, and, in a central region, is provided with an accommodation sleeve for the lower longitudinal bar 5 so that thereby the forward support rail 3 will be shiftable along this bar.
• An accommodation sleeve is correspondingly provided at the upper end of the upper shank 15 for shiftable accommodation of the upper, longitudinal bar 6.
• the hinges 24 are disposed immediately beneath the trans ⁇ verse strut 21 and fully correspond to the above-mentioned hinges with the same reference numeral. Naturally, the hinges 24 also in this embodiment may possibly be placed as low down as is shown in Fig. 3. In association with the right-hand end in Fig. 4 of the lower straight portion 33, there is provided a sustaining leg 35 whose upper end is secured in the hinge 24 mounted in this position.
• the transverse strut 21 is provided with sliding sleeves 26 for adjustable anchorage of the support members 12 with their slip guards 28.
• the hinges 24 are located im ⁇ mediately adjacent the underside of the transverse strut 21, it is possible according to the invention to place the longitudinal bar 5 on the upper side of the transverse strut in order thereby to reduce the constructional height which the drive-on ramps (either the separate ramps desig ⁇ nated 7 or the ramps directly provided on the support mem ⁇ bers 12) must negotiate.
