Abstract

A pair of frames, one for each end of the vehicle to be lifted, are attached to the chassis or body of the vehicle via special attachment brackets e.g. at (I). Once attached, the vehicle can be raised by drawing a threaded block (E), running on rollers, up an inclined plane of a support structure (L) by turning a nut attached to a length of threaded rod (D) which engages with the threaded (H) block (E). The threaded block drives a pair of lifting struts (F) which are attached to a lifting arm (B), one end of which is pivoted on the frame (L) and the other end of which has a rotating head (C) which is coupled to the vehicle. When each end of the vehicle is raised to a sufficient height, the vehicle can be rotated through 360 degrees and secured at various angles by inserting a pin (J) into the indexing plate (C) on the rotating head. <IMAGE>

Description

CHASSIS TILTER FOR MOTOR CNRS This invention relates to a device for lifting and rotating the chassis of a motor car or the like.

There are a number of systems used to provide access to the underside of motor cars for repair. These include lifting devices such as ramps as well as pits into which the mechanic can descend. The chassis tilter, the subject of this application, however, combines both lifting the car and rotating it around its longitudinal axis to provide very good access to the underside for repair.

The present invention comprises lifting devices for each end of the motor car, or the like. Each of these lifting devices comprises mountings, to permit fixture to the car itself, as well as a pivot mechanism to allow the car to be rotated around a longitudinal axis.

These mountings can be adapted, possibly through the use of specially designed fitments, to fit a wide range of cars.

n specific embodiment of the invention is now described by way of example only, with reference to the accompanying drawings.

Fig. 18 shows the attachment to adapt one of the lifting frames to act as an engine lift.

Referring to Fig. 1. Shows one of a pair of handed frames resting on a pair of legs (K) which run parallel to the centre axis of the chassis to be lifted and joined by a cross frame (A) onto which is welded a support structure (L). A lifting arm (B) is pivoted at one end of the support structure by a pin (G) and can be lifted by the lifting struts (F) which are pivoted at the lifting arm. The bottom ends of the lifting struts are pivoted on the threaded roller lift block (E) which can be drawn up the sloping support structure by the lift screw (D).

The lift screw is rotated at the upper end by the lift screw nut (H).

A rotating head (C) is pinned to the lifting arm (B) so that it can rotate through 360 degrees and has two arms welded to the indexing disc which terminate in two adaptor mounting points (I) onto which can be attached various mountings designed to fix to convenient points on the car to be lifted. These points are typically the bumper mountings. Figs. 7 through 17 illustrate a sample range of such attachments to join the rotating head to the bumper mountings of various cars.

Once the subject car has been attached to the rotating head and lifted to a sufficient height, it can be rotated and locked in position by inserting a locking pin (J) through the index disc.

The lifting frame can be adapted to an engine lift or crane by replacing the rotating head with the attachment as shown in Fig. 18,

Claims

CAR CHASSIS TILTER. CLAIMS.

CLAIM 1. A car chassis tilter comprising a pair of free-standing end frames each with a pivoted lifting arm and rotating head for connection to the car chassis which is raised and lowered by means of a mechanical screw operating on an inclined plane.
CLAIM 2. A car chassis tilter as claimed in CLAIM 1 whereby the pivoted lifting arm and rotating head on each frame is raised by means of drawing a threaded block up an inclined plane on a length of threaded shaft.
CLAIM 3. A car chassis tilter as claimed in CLAIM 2 such that the threaded block moves on the inclined plane on wheels or bearings so that no bending load is transfered to the threaded shaft.
CLAIM 4. A car chassis tilter as claimed in CLAIM 3 whereby the threaded shaft is retained at the upper end such that any downward load placed on the threaded block results in the threaded shaft being placed in tension.
CLAIM 5. A car chassis tilter as claimed in CLAIMS 1, 2, 3, & 4 whereby the threaded block is connected to the lifting arm and hence to the rotating head by a strut or struts which operate in compression to actuate the lifting arm with the movement of the threaded block on the threaded shaft.
CLAIM 6. A car chassis tilter as claimed in CLAIM 1 whereby a rotating head is allowed to revolve through 360 degrees at the lifting end of the lifting arm and to be locked in a variety of positions.
CLAIM 7. A car chassis tilter as claimed under CLAIMS 1 & 6 w"r the rotating head comprises a method of attaching su"-as= brackets to connect a variety of cars to the chassis - tilter frame at each end of the car.
CLAIM 8. A car chassis tilter as claimed under CLAIMS 1, 6 & 7 whereby the connection between the rotating head and the chassis attachment brackets designated as the adaptor mounting points allow the attachment brackets to pivot in the horizontal axis when the adaptor mounting points are parallel to the ground.
CLAIM 9. A car chassis tilter as claimed under CLAIMS 6, 7, & 8 where the adaptor mounting points on the rotating head are set at a position to allow the adaptor mounting points to pivot at a point at variance to the centre pivot of the rotating head such that the chassis to be tilted can be mounted with the centre of gravity of the chassis tri aligned with the centre pivot of the rotating head.
CLAIM 10. A car chassis tilter as described in the Specification and the Description and attached drawings previously submitted.
