Abstract
Abstract The present invention concerns a load transfer device for platforms intended for the stacking of articles and exhibiting wheels, in particular for platforms for parking motor vehicles in a garage built in honeycomb style, with parking cells arranged adjacent to a shaft and a movable transport compartment in the shaft, whereby the platforms can be shifted between transport compartment and parking cell by means of crank mechanisms.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
A load transfer device for platforms intended for the stacking of articles and exhibiting wheels, in particular for platforms for parking motor vehicles in a garage built in honeycomb style, with parking cells arranged adjacent to a shaft and a movable transport compartment in the shaft, whereby the platforms can be shifted between transport compartment and parking cells by means of crank mechanisms, two crank mechanisms being arranged in the transport compartment, each being provided with two equally long crank arms, on the end of each of which a roller is provided which engage a slot on the underside of a platform, the center of rotation of each of the crank mechanisms being capable of being pushed out and pulled in in the direction of the platform displacement.
Claim 2
Dependent Claim
128 words
A load transfer device for platforms intended for the stacking of articles and exhibiting wheels, in particular for platforms for parking motor vehicles in a garage built in honeycomb style, with parking cells arranged adjacent to a shaft and a movable transport compartment in the shaft, whereby the platforms can be shifted between transport compartment and parking cells by means of crank mechanisms, two crank mechanisms being arranged in the transport compartment, each being provided with two equally long crank arms, on the end of each of which a roller is provided which engage a slot on the underside of a platform, the center of rotation of each of the crank mechanisms being capable of being pushed out and pulled in in the direction of the platform displacement.
Claim 3
Dependent Claim
24 words
A load transfer device according to claim 1, wherein the two crank mechanisms are capable of being driven synchronously and counter-rotating toward one another.
Claim 4
Dependent Claim
55 words
A load transfer device according to claim 1, wherein the pushing-out and the pulling-in motion of the crank mechanisms takes place simultaneously with the crank rotation, whereby the pushing-out motion of the center of rotation corresponds to a crank rotation of 180* and the pulling-in motion corresponds to a further uninterrupted crank rotation of 180*.
Claim 5
Dependent Claim
32 words
A load transfer device according to claim 1, wherein the centers of rotation of the crank mechanisms are arranged on a frame which is movable in the direction of the platform movement.
Claim 6
Dependent Claim
51 words
A load transfer device according to claim 1, wherein the centers of rotation of the crank mechanisms are arranged on the end of a rocking lever supported in a stationary frame in the transport compartment, the end of this rocking lever being movable essentially in the direction of the platform displacement.
Claim 7
Dependent Claim
33 words
A load transfer device according to claim 5, wherein a further crank mechanism is arranged in the transport compartment, with the roller of this crank mechanism engaging a slot of the rocking lever.
Claim 8
Dependent Claim
77 words
A load transfer device according to claim 6, wherein the crank mechanisms for shifting the platform, as well as the further crank mechanisms for rotating the rocking lever are capable of being driven by a chain drive and/or a gear drive, whereby the working diameter of the sprocket wheels or gear wheels of the drive of the rocking lever is twice as great as that of the sprocket wheels of the crank mechanism for shifting the platform.
Claim 9
Dependent Claim
34 words
A load transfer device according to claim 1 wherein the crank mechanisms are moved at increased speed during the period of a no-load movement, i.e. before or after the crank rollers engage the slots.
Claim 10
Dependent Claim
25 words
A load transfer device according to claim 1, characterized in that it is located asymmetrically in the transport compartment and thus asymmetrically in the shaft.
