Abstract:
Tension apparatus for use e.g. in conjunction with an automobile body straightener, said tension apparatus consisting of a frame (1), an interlocking gear (2) attached to the first end of the frame, and a vertical arm (3) attached to the second end. The interlocking gear consists of two essentially identical locking plates (4, 5) mounted opposite to each other in a mirror-image configuration relative to the horizontal centre axis of the tension apparatus. Each locking plate comprises two joint frames (6, 7) placed at a distance from each other and so positioned that they partially overlap when the locking plates are placed oppositely. Between the joint frames is a tightening means (8), e.g. an eccentric shaft, which can be rotated so as to turn the locking plates relative to each other.
Abstract:
Quick-action fastener designed to be used e.g. for the fastening of the supporting legs of the body clamps of an automobile body straightener, said fastener consisting of a frame, reinforcing plates (1) attached to the frame, a locking element (2) pivoted on the frame, and a tightening means (3) for securing the fastener firmly in place. The tightening means (3) is an eccentric shaft and the locking element (2) is provided with a stop face (4) against which, when the quick-action fastener is being locked in place, the eccentric part of the tightening means is pressed as the eccentric shaft is rotated.
Abstract:
The present invention relates to an arrangement for a longitudinal portable aligner for damaged vehicle bodywork and vehicle chassis, in conjunction with which the aligner consists of a lower part (1) executed as a frame and an upper part (2), a so-called slide, mounted in it in such a way as to be capable of displacement. The aligner is equipped with folding wheels (19) capable of adjustment between a working position, in which the aligner is in contact with the floor, and a transport position, in which the aligner adopts a free position relative to the floor. The invention is characterized in that the wheels (19) are rotatably arranged on a wheel carrier executed as a U-shaped balance arm (17) and so arranged as to engage around the lower part (1) and pivotally mounted on the outsides of the lower part, so that the wheels (19) can be caused to oscillate about the fulcra of the balance arm (17) via the force exerted on the web of the balance arm. The balance arm (17) consits essentially of two two-armed lever arms (18), which are connected to one another via a transverse bridge (20), which then interacts with a locking mechanism (21) for the wheel carrier.
Abstract:
A body clamp for an automobile body straightener, consisting of a main body (2) which can be fastened to a straightener frame beam (1) and has a pair of jaws (3, 4) attached to it, one of which is fixed to the main body and the other (4) turnably mounted on a shaft (5) attached to the main body (2), the body clamp being provided with a closing device (6), e.g. a heart wheel, by means of which the turnable jaw (4) can be pressed against the fixed jaw (3). The closing device (6) is turnably mounted on a shaft (7) attached to the movable jaw (4) so that, when the closing device (6) is pressed (G) against the frame beam (1), it will generate a clamping force (F) between the jaws, with the result that the body clamp is simultaneously fastened to the straightener frame beam (1) when the jaws (3, 4) are closed.
Abstract:
A car body frame straightening apparatus consisting of a frame jig and a rim clamp having an adjustable attachment to the jig frame and comprising of a pair of jaws clamping to the body rim. One jaw (3) of the rim clamp is permanently fixed to a body piece (5) of the rim clamp (2) while the other, an adjustable clamp (4), is clampable by means of an eccentric clamping member (6) against the other jaw (2) in such a way that the rim clamp is clamped by virtue of another set of eccentric elements (7, 8), which exert a clamping effect on the jig frame (1), to attach to the beam frame.
Abstract:
Car body rectifying means (10) comprising a frame (11), and a rectifying table (12) disposed to be movable in vertical direction relative thereto, attachments (13) or equivalent on the rectifying table (12) to which the vehicle can be secured. To the rectifying table (12) of the rectifying means or to a frame portion connected therewith and moving along therewith or to a frame portion (11) which is fixed with reference to the rectifying table has in the horizontal plane slidably been connected a rectifying unit (40). The rectifying unit (40) comprises a frame (41) consisting of a first frame portion (42) and of a second frame portion (70) slidably disposed with reference to said first frame portion, and said rectifying unit (40) comprises means (47, 60) for performing rectifying work both on the frame beams of the car and on the body structures themselves, the rectifying forces being directable on the object to be rectified in horizontal as well as vertical direction.
Abstract:
Procedure in car body rectifying work. In the procedure the vehicle is driven onto the rectifying table (11) of the car body rectifying means (10) and affixed to skirt attachments (12) provided on the rectifying table. The vehicle is raised, while it is on the rectifying table, with the lifting means (16) of the vehicle rectifying means to desired height for the rectifying work. Hereafter the lifting means (16) is removed from under the vehicle and out of functional connection with the rectifying table (11) and the vehicle is left resting on supporting legs (30) connected with the rectifying table (11). The invention also relates to appparatus conforming to the procedure.
Abstract:
The invention pertains to a fixable pivoting element (1, 1 , 1 ) comprising two composite disks (2) provided with spur teeth. The pivoting element is used for force guidance and deflection for restoring deformed vehicle bodies on work benches. The spur toothing (3) consists of a number of outwardly diverging (from the central point to the radial perimeter) tooth flanks which engage in the matching spur toothing of an opposing composite disk (2) and when released can be adjusted radially in small angles. This arrangement permits hitherto unattainable extremely buckle- and bending- resistant rigid force deflections in vehicle bodies with angular deformations. Additional tools, deflection rollers and securing points are no longer necessary. In addition, with the proposed force deflection device, tension and compression forces from the tension beam outward and combinations of these forces can be transmitted to the vehicle body to effect straightening.
