Method and device for detachable coupling together of implement and vehicle

Claim 2

Method of detachable coupling together a loader, bucket, crane or other implement, in cantilever fashion to the end of a vehicle, said implement being vertically swingable and being pivotally attached to a vertically extending base and further being provided with a pair of downwardly extending legs, each leg of said pair being respectively spaced outwardly of the base, characterized in that the base of the implement is furnished with one or more coupling means, which essentially in a vertical direction, are detachably coupleable, lockable and self-centering in complementary engaging means located in vertically spaced relationship on the end of the frame of the vehicle, said coupling means on said base extending outwardly therefrom and being T-shaped in configuration, said complementary engaging means having a complementary downwardly extending opening with a transverse slot at the top of said opening for restraining said T-shaped coupling means from horizontal shifting, that the vehicle is driven up to the implement set up on the supporting legs, that the coupling and engaging means are brought into a roughly pre-centered starting position for coupling, that the coupling means on the implement are lowered by the supporting legs relative to the engaging means on the vehicle for effecting the coupling, the coupling and engaging means being automatically centered in relation to one another, brought into engagement, locked and detachably held together, and wherein the coupling means is insertable into and within the engaging means.

Claim 3

Method according to claim 1, characterized in that the raising and lowering are effected hydraulically after the implement, in starting position and not yet coupled to the vehicle, has been, connected to a hydraulic pressure source on the vehicle.

Claim 4

Device for detachable coupling of a loader, bucket crane or other implement in cantilever fashion to The end of a framed vehicle, the implement being of the type which is vertically swingable and pivotally attached to a vertically extending base and which includes a pair of downwardly extending legs, each leg of the pair being respectively spaced outwardly of the base, wherein the device further comprises: vertically tapering T-shaped coupling means furnished on the base of the implement and disposed at two heights, the coupling means extending outwardly from the base; engaging means complementary to the coupling means located in vertically spaced relationship on the end of the frame of the vehicle and having a complementary downwardly extending opening with a transverse slot at the top of the opening for restraining the coupling means from horizontal shifting; and the coupling means being essentially, in a vertical direction, detachably coupleable, lockable and self-centering in the engaging means such that the vehicle is driven up to the implement set up on the supporting legs, that the coupling and engaging means are brought into a roughly pre-centered starting position for coupling, that the coupling means and the implement are lowered by the supporting legs relative to the engaging means on the vehicle for effecting the coupling, the coupling and engaging means being automatically centered in relation to one another, brought into engagement, locked and detachably held together, and wherein the coupling means is insertable into and within the engaging means.

Claim 5

Device for detachable coupling of a loader, bucket crane or other implement in cantilever fashion to The end of a framed vehicle, the implement being of the type which is vertically swingable and pivotally attached to a vertically extending base and which includes a pair of downwardly extending legs, each leg of the pair being respectively spaced outwardly of the base, wherein the device further comprises: vertically tapering T-shaped coupling means furnished on the base of the implement and disposed at two heights, the coupling means extending outwardly from the base; engaging means complementary to the coupling means located in vertically spaced relationship on the end of the frame of the vehicle and having a complementary downwardly extending opening with a transverse slot at the top of the opening for restraining the coupling means from horizontal shifting; and the coupling means being essentially, in a vertical direction, detachably coupleable, lockable and self-centering in the engaging means such that the vehicle is driven up to the implement set up on the supporting legs, that the coupling and engaging means are brought into a roughly pre-centered starting position for coupling, that the coupling means and the implement are lowered by the supporting legs relative to the engaging means on the vehicle for effecting the coupling, the coupling and engaging means being automatically centered in relation to one another, brought into engagement, locked and detachably held together, and wherein the coupling means is insertable into and within the engaging means.

Claim 6

Device according to claim 3, characterized in that the supporting legs are extensible and withdrawable by means of hydraulic cylinders and are connectable to a hydraulic pressure source on the vehicle.

Claim 7

Device according to claim 3, characterized in that one or more of the engaging means are arranged on the vehicle at a height such that they at the same time serve as under-driving protection.
